DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 11 As shown, in this scheme, a single-driver driven air outlet device with dual air outlets that changes wind direction is mainly installed in the car compartment. It is used to connect the car compartment with the air outlet of the car air conditioner, and change the wind direction of the hot and cold air blown out of the car air conditioner according to the blowing needs of the passengers.

[0036] An air outlet device with a single driver driving the wind direction change of dual air outlets includes two detachably connected shells 1, each shell 1 has an inner cavity, and each shell 1 has an air inlet 2 and an air outlet 3 connected to the inner cavity; a driving member 10, which is connected between the two shells 1; a swinging member 4 is swingably provided in each inner cavity, and the upper and lower ends of the swinging member 4 are movably abutted against the inner side wall of the inner cavity, and the driving member 10 is used to drive the swinging members 4 in the two inner cavities to swing in the inner cavity; when the swinging member 4 swings in the inner cavity, the air inlet 2 and the air outlet 3 can be isolated, or the inner cavity can be isolated into an upper air outlet 5 and / or a lower air outlet 6.

[0037] The air inlet 2 and the air outlet 3 at both ends of the housing 1 correspond to the air outlet of the vehicle air conditioner and the vehicle compartment respectively. Figure 6 As shown, the swing member 4 separates the interior of the housing 1 into an upper air outlet 5 and a lower air outlet 6. At this time, the wind entering the housing 1 from the air inlet 2 is blown out along the upper air outlet 5 and the lower air outlet 6 formed on both sides of the swing member 4; when the driving member 10 drives the swing member 4 according to Figure 6When the swing member 4 swings to the left in the direction shown, the lower end of the swing member 4 gradually approaches the right inner wall of the housing 1, the lower air outlet 6 is gradually closed and the wind force of the upper air outlet 5 is gradually increased until the swing member 4 swings to the position shown in FIG. Figure 7 In this state, the lower air outlet 6 is completely closed, and the air entering the housing 1 from the air inlet 2 is all blown out from the upper air outlet 5; when the driving member 10 drives the swing member 4 to Figure 6 When the swing member 4 swings to the right, the lower end of the swing member 4 gradually approaches the left inner wall of the housing 1, the upper air outlet 5 is gradually closed and the wind force of the lower air outlet 6 is gradually increased until the swing member 4 swings to Figure 8 In the position shown, the upper air duct 5 is completely closed, and the air entering the housing 1 from the air inlet 2 is all blown out from the lower air duct 6; when the driving member 10 drives the swing member 4 to swing to Figure 9 In the position shown, the swing member 4 is approximately intercepted laterally in the housing 1 and isolates the air outlet 3 from the air inlet 2. At this time, the air outlet 3 device is closed.

[0038] Preferably, the driving member 10 can be a motor or a rotary cylinder, and the detachable connection between the two shells 1 can be realized by a threaded connection, that is, a connecting rod is arranged between the two shells 1, and the connecting sections of the connecting rod along the axial direction are provided with threaded holes, and bolt through holes are provided at the opposite ends of the two shells 1. The bolts pass through the bolt through holes and are connected in the threaded holes to fix the two shells 1.

[0039] Furthermore, the swing member 4 includes a main body plate 7 and a plurality of blades 8 arrayed and distributed on both side walls of the main body plate 7 . The cross section of the blades 8 is arc-shaped, and the blades 8 in the two inner cavities are symmetrically arranged relative to the middle connecting line of the two shells 1 .

[0040] The cross section of the blade 8 is set to an arc shape and the swing members 4 in the two shells 1 are symmetrically arranged along the middle connecting line of the two shells 1, so that the air outlet 3 device can have both wind gathering and dispersed blowing modes in each air outlet state. Specifically, Figure 6 As shown, in this state, the air outlet device is in a state where both the upper air outlet 5 and the lower air outlet 6 are open, and the three-dimensional state of the swing member 4 is set as Figure 3 As shown, in this state, the wind blowing in from the air inlet 2 moves along the side wall of the blade 8 toward Figure 3 When the driving member 10 drives the swing member 4 from Figure 3 The status shown turns to Figure 4 In the state shown (the swing member 4 is turned 180 degrees in the housing 1), the wind blown in from the air inlet 2 in this state moves along the side wall of the blade 8 toward Figure 4The middle position is gathered to achieve the effect of wind gathering. In the case of one-sided air outlet of the upper air outlet duct 5 or the lower air outlet duct 6, due to the arc-shaped arrangement of the cross section of the blade 8 and the symmetrical arrangement of the blade 8, the blade 8 can also present two modes of wind gathering and dispersing.

[0041] Further, the upper and lower ends of the main plate 7 are provided with soft rubber sheets. In the case of one-sided air outlet of the upper air outlet duct 5 or the lower air outlet duct 6 or isolation of the air inlet 2 and the air outlet 3, the upper and / or lower end of the main plate 7 needs to be abutted against the inner wall of the shell 1, and the soft rubber sheets arranged at the upper and lower ends of the main plate 7 are used to increase the sealing performance between the swing member 4 and the inner wall of the shell 1. Preferably, the soft rubber sheets are integrally formed with the main plate 7 or are separately arranged. When the main plate 7 is integrally formed with the soft rubber sheets, the main plate 7 can be made of plastic material, and the main plate 7 and the soft rubber sheets are integrally formed by two-color mold injection molding.

[0042] Further, the output end of the driving member 10 is provided with a driving wheel 9, and each swing member 4 is provided with a first driven member 11 and a second driven member 12 at two ends along the length direction.

One of the second driven members 12 is engaged with the driving wheel 9, and the other second driven member 12 is in transmission connection with the first driven member 11 and the driving wheel 9.

[0043] When working, the driving member 10 drives the driving wheel 9 to rotate, and the driving wheel 9 drives the two first driven members 11 and the two second driven members 12 to rotate when rotating, and the first driven member 11 and the second driven member 12 drive the swing member 4 to swing in the shell 1 when rotating.

[0044] Further, the first transmission wheel 13 is rotationally arranged at the end of the shell 1 away from the other shell 1, and the first transmission wheel 13 is in transmission connection with the first driven member 11. Each shell 1 is provided with a transmission shaft 16, and the two ends of the two transmission shafts 16 are provided with second transmission wheels 14. The two second transmission wheels 14 at the end of the two transmission shafts 16 close to each other are coaxially arranged, and the other two second transmission wheels 14 are engaged with the corresponding first transmission wheels 13. The other second driven member 12 and one of the corresponding second transmission wheels 14 are provided with a third transmission wheel 15.

[0045] The first transmission wheel 13, the second transmission wheel 14, the third transmission wheel 15 and the transmission shaft 16 are used to transmit the output of the driving member 10 to the swing member 4, so as to realize the swing of the swing member 4 in the shell 1.

[0046] The two sides of the swing member 4 along the length direction are eccentrically arranged on the first driven member 11 and the second driven member 12.

[0047] Because the installation position reserved for the air outlet 3 device is small due to the compact space in the vehicle, the shell 1 needs to be made into an upper large and lower small shape. Because the inside of the shell 1 is a taper shape with the upper large and lower small, if the blade 8 directly rotates in the shell 1, the blade 8 will interfere with the inner wall of the shell 1 and cannot complete 180 rotation. If the inside of the shell 1 is made large, the volume of the entire mechanism will be increased. If the structure is made eccentric, the blade 8 will have an upward action in the rotating process, so that the blade 8 can complete the rotating action in the larger space inside the shell 1, without increasing the volume of the shell 1.

[0048] Specifically, the two second followers 12 each include a first driven gear 25, the first driven gear 25 is in transmission connection with the driving wheel 9, and the two first driven gears 25 are coaxially provided with a first connecting piece 26 at one end close to the shell 1. The first connecting piece 26 is provided with a rotating shaft 27 at an end away from the first driven gear 25, the axis direction of the rotating shaft 27 is parallel to the axis direction of the first connecting piece 26, the outer side wall of the rotating shaft 27 is sleeved with a second driven gear 28, the axis direction of the second driven gear 28 is collinearly arranged with the axis direction of the rotating shaft 27, and the second driven gear 28 is provided with two first mounting holes 29. The oscillating piece 4 is provided with two first mounting pins 30 at one end close to the second follower 12, and the first mounting pins 30 are inserted into the first mounting holes 29. The first follower 11 includes a third driven gear 31, the third driven gear 31 is coaxially provided with a second connecting piece 34 at one end close to the oscillating piece 4. The second connecting piece 34 is provided with a second mounting pin 32 at an end away from the third driven gear 31, the axis direction of the second mounting pin 32 is parallel to the axis direction of the second connecting piece 34, the oscillating piece 4 is provided with a second mounting hole 33 at one end close to the first follower 11, the second mounting pin 32 is inserted into the second mounting hole 33, and the axis direction of the second mounting hole 33 is collinear with the axis direction of the second driven gear 28.

[0049] Preferably, the two shells 1 are each provided with a gear groove 35 at one end close to each other, and the second follower 12 is rotationally arranged in the gear groove 35. The gear groove 35 is arranged to prevent the second driven gear 28 from shaking on the shell 1 when the first driven gear 25 drives the second driven gear 28 to eccentrically rotate.

[0050] Further, the scheme also includes a cover plate 24, the cover plate 24 is arranged on the air outlet 3 and divides the air outlet 3 into an upper air outlet 17 and a lower air outlet 18.

[0052] Further, the two side walls of the shell 1 along the length direction are folded towards the middle position of the shell 1 to form air guide walls 23, and the air guide walls 23 and the side wall of the cover plate 24 jointly form the upper air outlet 17 and the lower air outlet 18.

[0053] The air guide wall 23 and the upper surface of the cover plate 24 jointly form the upper air outlet 17 and the lower air outlet 18, so that the wind direction of the air blown out of the shell 1 is more controllable.
