Description

Technical Field

[0001] The present invention relates to the field of automotive parts, and more specifically, to an automotive air-conditioning air outlet. Background Art

[0002] Air conditioners have become standard components in automobiles. To meet the blowing comfort of passengers, air-conditioning air outlets are specifically provided in front of the seats. At the same time, the air-conditioning air outlets can adjust the wind direction and wind force according to the usage needs of passengers.

[0003] During use, a triple adjustment switch is often provided on one air-conditioning air outlet, which are respectively used to adjust the longitudinal blowing angle, the transverse blowing angle, and the blowing magnitude. To ensure the smoothness of the three adjustments, they are misaligned and adjustment switches are respectively provided for control. At this time, either the transverse adjustment blade or the longitudinal adjustment blade is always arranged inside the air outlet. When the adjustment blade arranged inside passes through the area of the adjustment blade arranged outside, its adjustment effect will be greatly reduced. The adjustment wind direction of the adjustment blade arranged inside is dispersed, and the wind force in the target area is insufficient, resulting in a poor adjustment effect of the adjustment blade arranged inside. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automotive air-conditioning air outlet that can ensure sufficient and concentrated wind force in the target area and can be stably adjusted both horizontally and vertically.

[0005] The technical solution adopted by the present invention to solve the above problems is: an automotive air-conditioning air outlet, including an air outlet duct. The air outlet end of the air outlet duct is provided with a main blade for adjusting the longitudinal air outlet angle and a secondary blade group composed of a plurality of secondary blades for adjusting the transverse air outlet angle. The plurality of secondary blades are arranged in an array on the main blade, and an adjustment switch for simultaneously adjusting the main blade and the secondary blades is further provided on the main blade.

[0006] Compared with the prior art, the advantages of the present invention are as follows: The main blade and the secondary blades are connected, and both the main blade and the secondary blades are arranged at the air outlet end of the air outlet duct. At this time, the air-conditioning air discharged from the air outlet duct passes through the main blade and the secondary blades, and the distance to the target area is the set distance. The wind force is sufficient and concentrated, and the wind direction adjustment is comfortable. In the design of the traditional air outlet, the secondary blades are built-in, so that the air-conditioning air first passes through the secondary blades and then through the main blade. Although the distance of the air-conditioning air reaching the target area remains unchanged when it is discharged from the air outlet duct, the wind direction changed by the secondary blades is interfered. The air-conditioning air adjusted by some of the secondary blades will collide with and rebound from the air outlet duct, forming a wind vortex, resulting in the cancellation of the wind force, and the wind force is reduced and the wind direction is dispersed. Similarly, if the main blade is built-in, the wind force will also be reduced and the wind direction will be dispersed. At the same time, by connecting the main blade and the secondary blades, the purpose of adjusting two wind directions can be achieved through one adjustment switch, reducing the number of adjustment switches at the air outlet, making the design of the air outlet more simple and easy to operate.

[0007] As an improvement of the present invention, one end of the main blade away from the air outlet end is rotatably connected to the air outlet duct, the adjustment switch is arranged at one end of the main blade close to the air outlet end, the secondary blade group includes one driving secondary blade, the adjustment switch drives the driving secondary blade to rotate, and the driving secondary blade can drive other secondary blades to rotate synchronously. Through the above improvement, the purpose of adjusting the main blade and the secondary blade group can be achieved only through one adjustment switch. When the adjustment switch is longitudinally toggled, the main blade can rotate to achieve longitudinal wind direction adjustment. When the adjustment switch is horizontally toggled, the secondary blade group rotates to achieve horizontal wind direction adjustment.

[0008] As an improvement of the present invention, the secondary blade is provided with a fastening groove for fastening on the main blade, the main blade is provided with a row of rotation holes arranged in an array, and the fastening groove is provided with rotation columns for rotatably connecting with the rotation holes. The secondary blade is also provided with connecting columns, and the connecting columns are arranged on the extension line of the fastening groove away from the main blade. Each of the connecting columns is rotatably connected to a transmission rod. Through the above improvement, the design of the fastening groove can fasten the secondary blade on the main blade to achieve the purpose that both the main blade and the secondary blades are arranged at the air outlet end of the air outlet duct. The matching design of the rotation holes and the rotation columns can ensure that when the secondary blade is fastened on the main blade, without affecting the use of the main blade, the secondary blade has the function of adjusting rotation. The design of the connecting columns and the transmission rod can achieve that when the adjustment switch adjusts the driving secondary blade, it can drive other secondary blades to be adjusted together to achieve the purpose of overall adjustment of the secondary blade group.

[0009] As an improvement of the present invention, the rotation hole is formed by the side wall of the main blade and two elastic abutting blocks. An embedding groove connected to the rotation hole is formed between the two abutting blocks. The embedding groove is wedge-shaped. The rotation column is rotationally connected to the rotation hole by passing through the embedding groove. Through this improvement, when the secondary blade is installed on the main blade, the elastic design of the abutting blocks and the design of the embedding groove can make it easier to install the rotation column into the rotation hole. After the rotation column is installed in the rotation hole, it is not easy to disengage from the rotation hole, ensuring the connection quality of the rotation column. At the same time, due to the elastic design of the abutting blocks, when the rotation column rotates, the rotation column rotates more flexibly without jamming.

[0010] As another improvement of the present invention, a connection groove is provided on the secondary blade. The connection groove is provided on the extension line of the fastening groove away from the main blade. The connection column is arranged in the connection groove. A row of rotation connection buckles for rotationally connecting with each connection column is provided on the transmission rod. The end of the rotation connection buckle is arranged in the connection groove. Through this improvement, the overall synchronous transmission connection between multiple secondary blades can be realized. After the rotation connection buckle is buckled with the connection column, it is not easy to disengage between the rotation connection buckle and the connection column. Since the transmission rod is arranged in the air outlet duct, if the rotation connection buckle and the connection column are disengaged, the maintenance difficulty is relatively large. The design that the rotation connection buckle is not easy to disengage from the connection column can effectively ensure the service life of the air outlet duct and reduce the maintenance period.

[0011] As another improvement of the present invention, a driving column is provided on the driving secondary blade. The driving column is arranged in the fastening groove and on the side of the rotation column close to the main blade. A driving groove for cooperating with the driving column is provided on the adjustment switch. When the adjustment switch is toggled left and right, the driving groove drives the driving column to rotate around the rotation column. Through this improvement, the purpose of the adjustment switch to adjust the driving secondary blade is achieved.

[0012] As another improvement of the present invention, a socket groove for buckling with the main blade is provided on the adjustment switch. A limiting buckle is arranged in the socket groove. A horizontally arranged installation limiting block is provided on the main blade. The limiting buckle cooperates with the installation limiting block to prevent the adjustment switch from disengaging from the main blade and ensure the stability of the adjustment switch during horizontal movement. Through this improvement, the installation of the adjustment switch and the main blade is realized, and the stability of the installation and the stability of the adjustment switch driving the secondary blade and the main blade are ensured.

[0013] As an improvement of the present invention, the fastening groove on the driving secondary blade is also buckled with the adjustment switch. Through this improvement, the installation and movement stability of the adjustment switch are ensured, and the situation that the limiting buckle disengages from the installation limiting block when the adjustment switch is longitudinally toggled is avoided.

[0014] As an improvement of the present invention, the secondary blade is a vertically placed circle, and a spherical guide rail for cooperating with the secondary blade to rotate is provided on the air outlet duct. Through this improvement, through the design of the circular shape of the secondary blade and the spherical guide rail, it can be ensured that when the main blade is longitudinally pulled, the smoothness of the main blade pulling can still be guaranteed, and the adjustability of the secondary blade can be maintained. There is mutual independence between the main blade and the secondary blade during adjustment.

[0015] As an improvement of the present invention, transverse guiding steps are provided on both sides of the main blade, and both ends of the notch of the fastening groove are arranged on the guiding steps. Through this improvement, to ensure the smoothness of the transverse adjustment, there will be a gap between the fastening groove and the main blade. However, due to the design of the gap, the centering effect of the fastening between the main blade and the secondary blade will be poor. When the main blade is longitudinally pulled, it is easy to cause uneven stress between the main blade and the secondary blade, with a large force at the end. As a result, when the main blade is longitudinally pulled, it is more likely to cause damage to the main blade or the secondary blade. And through the design that both ends of the notch of the fastening groove are arranged on the guiding steps, it can achieve a small friction force between the main blade and the secondary blade, while ensuring the centering effect of the fastening between the main blade and the secondary blade, and ensuring the connection effect between the main blade and the secondary blade.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Such as Figures 1 - 3As shown, an air outlet of an automotive air conditioner includes an air outlet duct 1. At the air outlet end of the air outlet duct 1, there are main blades 2 for adjusting the longitudinal air outlet angle and a set of secondary blade groups composed of multiple secondary blades 3 for adjusting the lateral air outlet angle. The multiple secondary blades 3 are arranged in an array on the main blades 2. An adjustment switch 4 is also provided on the main blades 2 to simultaneously adjust the main blades 2 and the secondary blades 3.

[0022] One end of the main blade 2 away from the air outlet end is rotatably connected to the air outlet duct 1. The adjustment switch 4 is provided at one end of the main blade 2 close to the air outlet end. The secondary blade group includes a driving secondary blade 3.1. The adjustment switch 4 drives the driving secondary blade 3.1 to rotate, and the driving secondary blade 3.1 can drive other secondary blades 3 to rotate synchronously. A fastening groove 3.2 for fastening on the main blade 2 is provided on the secondary blade 3. A row of rotation holes 2.1 arranged in an array is provided on the main blade 2. A rotation column 3.3 for rotatably connecting with the rotation hole 2.1 is provided in the fastening groove 3.2. A connecting column 3.4 is also provided on the secondary blade 3. The connecting column 3.4 is arranged on the extension line of the fastening groove 3.2 away from the main blade 2. Each connecting column 3.4 is rotatably connected to a transmission rod 5.

[0023] As Figure 2 shown, the rotation hole 2.1 is formed by the side wall of the main blade 2 and two elastic abutting blocks 2.2. An embedding groove 2.3 connected to the rotation hole 2.1 is formed between the two abutting blocks 2.2. The embedding groove 2.3 is wedge-shaped. The rotation column 3.3 is rotatably connected to the rotation hole 2.1 by passing through the embedding groove 2.3.

[0024] A connecting groove 3.5 is provided on the secondary blade 3. The connecting groove 3.5 is arranged on the extension line of the fastening groove 3.2 away from the main blade 2. The connecting column 3.4 is arranged in the connecting groove 3.5. A row of rotation connection buckles 5.1 for rotatably connecting with each connecting column 3.4 is provided on the transmission rod 5. The end of the rotation connection buckle 5.1 is arranged in the connecting groove 3.5.

[0025] A driving post 3.1.1 is provided on the driving secondary blade 3.1. The driving post 3.1.1 is arranged in the fastening groove 3.2 and on the side of the rotating post 3.3 close to the main blade 2. A driving groove 4.1 for cooperating with the driving post 3.1.1 is provided on the adjusting switch 4. When the adjusting switch 4 is toggled left and right, the driving groove 4.1 drives the driving post 3.1.1 to rotate around the rotating post 3.3. A socket groove 4.2 for fastening with the main blade 2 is provided on the adjusting switch 4. A limiting buckle 4.3 is arranged in the socket groove 4.2. A horizontally arranged mounting limiting block 2.4 is provided on the main blade 2. The limiting buckle 4.3 cooperates with the mounting limiting block 2.4 to prevent the adjusting switch 4 from detaching from the main blade 2 and ensure the stability of the adjusting switch 4 during horizontal movement. The fastening groove 3.2 on the driving secondary blade 3.1 also fastens with the adjusting switch 4.

[0026] Such as Figure 1 , Figure 3As shown, the secondary blade 3 is in a vertically placed circular shape, and the air outlet duct 1 is provided with a spherical guide rail 1.1 for cooperating with the secondary blade 3 to rotate. Both sides of the main blade 2 are provided with transversely arranged guide steps 2.5. The two ends of the notch of the buckling groove 3.2 of the secondary blade 3 except for driving the secondary blade 3.1 are arranged on the guide step 2.5, which can play the role of centering the connection between the main blade 2 and the secondary blade 3. When the notch of the buckling groove 3.2 of the secondary blade 3 is separated from the guide step 2.5, when the secondary blade 3 is rotated toward the positive air outlet of the air outlet duct 1 again, the guide slope on the guide step 2.5 can move and guide the centering of the main blade 2. This method can also be used when the secondary blade 3 is buckled onto the main blade 2 to ensure that the secondary blade 3 is buckled. When it is put on the main blade 2, the main blade 2 is centered, and the two ends of the notch of the snap-fit ​​groove 3.2 of the driving secondary blade 3.1 are set on the adjusting switch 4. The adjusting switch 4 is used to realize the centering of the connection between the main blade 2 and the secondary blade 3. During installation, it is necessary to first install the adjusting switch 4 on the main blade 2, and then snap-fit ​​the driving secondary blade 3.1 to the main blade 2 and the adjusting switch 4. Otherwise, due to the design of the installation limit block 2.4, the adjusting switch 4 will not be able to be inserted into the main blade 2. At the same time, it also ensures that after the driving secondary blade 3.1 is installed, the adjusting switch 4 is difficult to detach from the main blade 2, and all the secondary blades 3 are restricted in the spherical guide rail 1.1 and will not expand, thereby achieving mutual snap-fitting and avoiding the risk of detachment. The regulating switch 4 is provided with a guide block 2.6 which cooperates with the guide step 2.5. Due to the design of the installation limit block 2.4 and the limit buckle 4.3, the installation limit block 2.4 is triangular, the inclined surface is used for the smoothness of the installation of the regulating switch 4, and a right-angled side is used to limit the movement of the regulating switch 4. However, its matching structure does not have much effect on the stability of the connection between the regulating switch 4 and the main blade 2, and when the regulating switch 4 is pulled up and down, the limit buckle 4.3 is also prone to abutment and wear with the installation limit block 2.4. At this time, the design of the guide step 2.5 is utilized to design a guide block 2.6 in the sleeve groove 4.2. When the installation of the limit block 2.4 and the limit buckle 4.3 is completed, the guide block 2.6 is abutted against the guide inclined surface of the guide step 2.5, which can effectively ensure the stability of the connection between the regulating switch 4 and the main blade 2. In order to ensure the effect of the abutment between the guide block 2.6 and the guide step 2.5, an elastic soft rubber 6 is designed between the main blade 2 and the regulating switch 4.

[0027] like Figure 3 As shown, in order to ensure the integrity of the air outlet, a switch plate 7 for adjusting the opening and closing of the air outlet duct 1 and the air outlet volume is provided on the inner side of the air outlet duct 1. The switch plate 7 is connected to the switch knob provided on the outer side of the air outlet duct 1 through a gear transmission assembly. The air outlet volume can be adjusted by adjusting the switch 4 knob.
