[0001] The present invention belongs to the field of automotive interiors, and particularly relates to a variable vane air outlet structure. Background Art

[0002] Automotive air vents are generally arranged on the instrument panel. In addition, some vehicle models are also equipped with top air vents and rear air vents. Currently, when the vanes swing to the upper and lower limits, the gap between the housing and the vanes is relatively large, and air flows out from the gap, resulting in poor air outlet effect. In addition, the current vane air guiding width is limited, and the air guiding effect is not good. Moreover, when the air blows out to the vane opening, the air outlet is small, and a large amount of flowing air blocks each other at the air outlet, forming an air barrier and ultimately affecting the effective blowing performance. Summary of the Invention

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-11 , the present invention provides the following technical solutions: A variable blade air outlet structure includes an upper blade assembly, a vertical blade assembly, and a lower blade assembly. The vertical blade assembly is between the upper blade assembly and the lower blade assembly. The upper blade assembly includes blade one 1, blade two 2, and upper blade bracket 11. Blade one 1 and blade two 2 are rotatably connected in a top-down manner. Therefore, blade two 2 can rotate around blade one 1. The upper blade bracket 11 is movably clamped on blade one 1 and meshes with one end of blade two 2. Therefore, after blade one 1 rotates, blade two 2 can be driven to rotate in the same direction through the upper blade bracket 11. Since the upper blade bracket 11 is movably clamped with blade one 1, it can move limitedly on blade one 1. After the upper blade bracket 11 and blade one 1 move in the same direction, they will continue to rotate under the action of inertia. Therefore, the rotation angle of blade two 2 will be greater than the rotation angle of blade one 1. When rotating to the limit state, compared with the case where the horizontal length of the upper blade assembly composed of the conventional blade, blade one 1, and blade two 2 is the same, the guiding width of the upper blade assembly composed of blade one 1 and blade two 2 is wider after rotation, and the guiding effect will be more excellent; by driving blade two 2 to rotate through blade one 1, the gap outside blade two 2 can be made smaller than that of the conventional blade, which can better reduce the outflow of excess air from the gap.

[0018] Specifically, a blade three 3 can also be movably and rotatably connected below the blade two 2. The blade three 3 can rotate around the blade two 2. Two torsion springs 12 are sleeved on the blade two 2. The two feet of each torsion spring 12 respectively abut against the blade two 2 and the blade three 3. And the two feet of one torsion spring 12 abut against one surface of the blade 2 and the blade three 3, while the two feet of the other torsion spring 12 abut against the other surface of the blade two 2 and the blade three 3. This enables the blade two 2 and the blade three 3 to rotate in the same direction and at the same angle. After the blade three 3 rotates, it abuts against the limit block 26. The upper blade assembly, the vertical blade assembly and the lower blade assembly are located inside the housing 18. The limit block 26 is arranged on the upper blade bracket 11 or the housing 18. When rotating to the point where the blade three 3 contacts the limit block 26, the blade two 2 continues to rotate, and the blade three 3 will be forced to rotate in the reverse direction around the blade two 2. When rotating to the limit state, compared with the upper blade assembly composed of the blade 1 and the blade two 2, its air guiding width is wider, and the gap outside the blade three 3 is smaller. Therefore, its air guiding effect and blowing effect will be more excellent.

[0019] Specifically, the lower blade assembly includes a blade four 4, a blade five 5, a blade six 6, a blade seven 7, a sub - blade one 8, a sub - blade two 9, two lower blade group brackets 15, two lower blade connecting rods 16 and two lower blade cranks 17. The two lower blade connecting rods 16 respectively connect one ends of the blade four 4 with the blade five 5 and the blade six 6 with the blade seven 7, connecting the blade four 4 with the blade five 5 and the blade six 6 with the blade seven 7. The upper parts of the two lower blade group brackets 15 are respectively movably sleeved on both ends of the blade four 4, the blade five 5, the blade six 6 and the blade seven 7. The blade four 4, the blade five 5, the blade six 6 and the blade seven 7 can rotate on the lower blade group brackets 15. The sub - blade one 8 is movably clamped on the blade four 4, and the sub - blade two 9 is movably clamped on the blade seven 7. The lower parts of the two lower blade group brackets 15 are clamped inside the lower sides of both ends of the sub - blade one 8 and the sub - blade two 9 to fix the distance between the lower sides of the sub - blade one 8 and the sub - blade two 9, enabling the lower ends of the blade four 4, the blade five 5, the blade six 6 and the blade seven 7 to be fixed and the upper ends to move limitedly around the blade four 4 and the blade seven 7 respectively, ensuring that the wind passes through the lower blade assembly and reducing the overflow of excess wind between the sub - blade one 8 and the housing 18 and between the sub - blade two 9 and the housing 18. The lower blade crank 17 is Z - shaped. One end of the lower blade crank 17 is clamped at one end of the blade five 5 and the blade six 6. The lower blade group bracket 15 is located between the lower blade crank 17 and the lower blade connecting rod 16.

[0020] Specifically, the vertical blade assembly includes a plurality of vertical blades 10, two vertical blade brackets 13 and a vertical blade connecting rod 14. The vertical blade brackets 13 are sleeved on both sides of the plurality of vertical blades 10. The vertical blade brackets 13 are connected to the housing 18. The vertical blade connecting rod 14 is connected to one side of the plurality of vertical blades 10, enabling the plurality of vertical blades 10 to swing together.

[0021] Specifically, the upper blade assembly, the vertical blade assembly, and the lower blade assembly are connected to a motor assembly. The motor assembly controls the rotation of the upper blade assembly, the vertical blade assembly, and the lower blade assembly, thereby forming an air guiding channel to blow out the wind. The motor assembly includes a motor bracket 19, a first motor 20, a second motor 21, a first motor crank 22, a second motor crank 23, and a transmission rack 24. The motor bracket 19 is connected to one side of the housing 18. The first motor crank 22 passes through the motor bracket 19 and is respectively connected to the first motor 20 and the first blade 1 at both ends. The upper part of the transmission rack 24 is connected to one end of the first motor crank 22, and the lower part is connected to the other ends of the two lower blade cranks 17. The transmission rack 24 is located outside the first blade 1. One end of the second motor crank 23 is connected to the vertical blade assembly, and the other end is connected to the second motor 21. The first motor 20 drives the rotation of the upper blade assembly and the lower blade assembly, and the second motor 21 drives the rotation of the vertical blade assembly.

[0022] Specifically, a first gear 101 is provided at one end of the first blade 1. One end of the first motor crank 22 is provided with a first spline 2201 and the other end is provided with a fourth gear 2202. The first spline 2201 on the first motor crank 22 is connected to the first motor 20. The first gear 101 meshes with the fourth gear 2202. The first motor 20 drives the rotation of the first blade 1 through the first motor crank 22. A second gear 201 is provided at one end of the second blade 2. A third gear 1101 is provided on the upper blade bracket 11. The second gear 201 and the third gear 1101 are engaged. When the first blade 1 rotates, the third gear 1101 on the first blade 1 drives the rotation of the second gear 201. Tooth marks 2401 are provided on the upper part of the transmission rack 24, and the tooth marks 2401 are adapted to the fourth gear 2201. Since the lower part of the transmission rack 24 is connected to the other ends of the two lower blade cranks 17, the two lower blade cranks 17 are connected to the fifth blade 5 and the sixth blade 6. The fifth blade 5 is connected to the fourth blade 4, and the sixth blade 6 is connected to the seventh blade 7. The movement of the fourth gear 2201 will engage with the tooth marks 2401 to drive the up and down movement of the transmission rack 24, thereby driving the fourth blade 4, the fifth blade 5, the sixth blade 6, and the seventh blade 7 to move together. Two stroke grooves 2402 are provided at the lower part of the transmission rack 24. The other ends of the two lower blade cranks 17 are inserted into the stroke grooves 2402 and slide therein. The two stroke grooves 2402 are curved. Therefore, the movement of the two lower blade cranks 17 in the stroke grooves 2402 will cause the two lower blade cranks 17 to rotate at a specific angle, thereby driving the rotation of the fourth blade 4, the fifth blade 5, the sixth blade 6, the seventh blade 7, the first auxiliary blade 8, and the second auxiliary blade 9.

[0023] Specifically, a cavity 202 is formed in the middle and lower part of the second blade 2. Rods for sleeving the torsion springs 12 are provided at both ends inside the cavity 202, and the two torsion springs 12 are sleeved on the two rods.

[0024] Specifically, the spline 2201 on the motor crank 22 is connected to the motor 20, and one end of the motor crank 23 is provided with a spline 2301, and the spline 2301 is connected to the motor 21.

[0025] Specifically, a panel 25 is connected to the top end of the housing 18, and the wind blows out from the panel 25 after passing through the blade assembly.

[0026] The movement process of the present invention is as follows: Figure 10 , at the beginning, the blade assembly is in the middle blowing state; then the motor 20 drives the blade 1 to rotate through the motor crank 22, and the blade 1 drives the blade 2 to rotate through the upper blade bracket 11. Since the upper blade bracket 11 is movably clamped with the blade 1, the rotation angle of the upper blade bracket 11 and the blade 2 will be greater than the angle of the blade 1 under the action of inertia. Then the blade 2 drives the blade 3 to rotate. Since there is a torsion spring between the blade 2 and the blade 3, the rotation angles of the blade 2 and the blade 3 are the same at the beginning. When the blade 3 continues to rotate and abuts against the limit block 26, the blade 3 will be forced to rotate reversely around the blade 2, thus forming the upper limit blowing state and the lower limit blowing state as shown in Figure 9 , 11 . In addition, the motor 20 will simultaneously drive the transmission rack 24 to move up and down, thereby driving the two lower blade cranks 17 to move in the stroke groove 2402, so that the two lower blade cranks 17 make a specific angle rotation under the action of the stroke groove 2402, thereby driving the blades 4, 5, 6, 7, the auxiliary blade 1 and the auxiliary blade 2 to rotate, and the motor 21 controls the rotation of the vertical blade assembly through the motor crank 23.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
