Description

Technical Field

[0001] The utility model relates to the technical field of automobile air outlets, in particular to a fixing and air leakage prevention structure for air outlet blades. Background Art

[0002] Automobile air condition outlets belong to automobile interior trim parts, generally arranged on the main and sub instrument panels. When the air conditioning refrigeration or heating mode is turned on, the interior environment temperature of the vehicle can be adjusted. By adjusting the air outlet blades, the blowing direction can be changed. As a very important functional and appearance part in automobile interior trim, the convenience and comfort of its operation have always been important aspects concerned by passengers.

[0003] In the prior art, air leakage and slight abnormal noise are likely to occur when the air outlet works, affecting the comfort experience of the driver and passengers. Moreover, the adjustment of the upper and lower blades in the air outlet is carried out through a dial. When the dial is not in use, since most of the dial is directly convex and exposed outside the air outlet, it will affect the overall aesthetics. And because the overall volume of the dial is relatively large, it will generate a large wind resistance, thus affecting the air outlet effect. Summary of the Utility Model

[0004] The utility model provides a fixing and air leakage prevention structure for air outlet blades, which is beneficial to reducing air leakage and abnormal noise, and is also beneficial to conveniently accommodating the convex part of the dial, ensuring the overall aesthetics and air outlet effect.

[0005] In order to solve the problems of the prior art, the utility model discloses a fixing and air leakage prevention structure for air outlet blades, including an air outlet body, an upper blade and a lower blade, and the upper blade and the lower blade are both installed in the air outlet body;

[0006] A fixing bracket is clamped at the middle position inside the air outlet body, and a decorative strip is connected to the outer surface of the fixing bracket;

[0007] Dial housings are arranged at both the left and right ends inside the air outlet body, and the dial housings are both installed on an adjacent upper blade on the same side. A dial protrusion is arranged at the upper end of the dial housing, and the dial protrusion extends downward into the dial housing. A receiving drive assembly is arranged inside each dial housing.

[0008] Further, a foam strip is connected to the lower edge of the air outlet body.

[0009] Further, each receiving drive assembly includes a positive and negative motor, a lead screw, a lifting block and two guide rods. The positive and negative motor is fixed at the bottom inside the dial housing, one end of the lead screw is connected to the power end of the positive and negative motor, and the other end of the lead screw is rotatably connected to the top inside the dial housing.

[0010] Furthermore, there are two lifting blocks, which are respectively fixed to the lower ends on the left and right sides of the toggle protrusion. One of the lifting blocks is threadedly sleeved on the lead screw. Both of the guide rods are fixed to the left and right ends inside the toggle housing, and the lifting blocks are slidably sleeved on the guide rods on the same side.

[0011] Furthermore, a storage battery and a relay are connected to the inner bottom of the toggle housing. The storage battery is connected in series with the relay, and there is a connecting cable between the relay and the forward and reverse motor.

[0012] Furthermore, an opening and closing switch is connected to the upper end of the toggle protrusion. The power connection end of the opening and closing switch is connected to a switch cable buried in the toggle protrusion, and there is a spring cable between the switch cable and the relay.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0014] 1. By installing the fixed bracket in the air outlet body in a snap-fit manner, since there is no gap in the external part of the air outlet body for snap-fit assembly, the only gap is the assembly gap of the plastic part, which is 0.05 mm on one side. This effectively prevents the generation of abnormal noises during the operation of the air outlet. Moreover, after installing the decorative strip, the only air leakage is the air leakage between the gaps. Therefore, the air leakage can be controlled by adjusting the assembly gap to prevent air leakage.

[0015] 2. Through the operation of the storage drive assembly, the toggle protrusion can be conveniently stored in the toggle housing. After the air direction is adjusted, it avoids the long-term exposure of the toggle protrusion outside, which is beneficial to ensuring the overall aesthetics of the air outlet. And the volume of the whole toggle becomes smaller, so the air resistance during air outlet can be reduced, thereby better improving the air outlet effect. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0021] A fixing and air leakage prevention structure for air outlet blades:

[0022] As Figure 1 、 2 shown, in this embodiment, it includes an air outlet body 1, an upper blade 5 and a lower blade 6. The upper blade 5 and the lower blade 6 are both installed inside the air outlet body 1. A fixing bracket 3 is clamped at the middle position inside the air outlet body 1, and a decorative strip 4 is connected to the outer surface of the fixing bracket 3;

[0023] By installing the fixing bracket 3 in the air outlet body 1 in a clamping manner, the clamping method is a common snap-fastener method on the market, so no more details will be described. Since there is no gap in the snap-fastener assembly outside the air outlet body 1, the only gap is the assembly gap of the plastic parts, which is 0.05mm on one side, effectively preventing the generation of abnormal noises during the operation of the air outlet. Moreover, after installing the decorative strip 4, the only air leakage is the air leakage between the gaps. Therefore, the air leakage can be controlled by adjusting the assembly gap, and the air leakage situation can be prevented accordingly.

[0024] As Figure 1 、 2 shown, in this embodiment, a foam strip 2 is connected to the lower border of the air outlet body 1.

[0025] When the air outlet body 1 is installed, the foam strip 2 contacts the pre-installed part. Due to its closed-cell structure, the foam strip 2 has good sound insulation effect and shock absorption performance, which can effectively reduce the wind noise when the air outlet blows air during vehicle driving and improve the riding comfort.

[0026] As Figure 1 、 3, as shown in FIGS. 4, in this embodiment, torsion knob housings 7 are provided at both the left and right ends inside the air outlet body 1. The torsion knob housings 7 are respectively mounted on an adjacent upper blade 5 on the same side. A torsion knob protrusion 8 is provided at the upper end of the torsion knob housing 7. The torsion knob protrusion 8 extends downward into the torsion knob housing 7. A storage drive assembly is provided inside each torsion knob housing 7. Each storage drive assembly includes a reversible motor 10, a lead screw 11, a lifting block 9, and two guide rods 12. The reversible motor 10 is fixed to the inner bottom of the torsion knob housing 7. One end of the lead screw 11 is connected to the power end of the reversible motor 10, and the other end of the lead screw 11 is rotatably connected to the inner top of the torsion knob housing 7. There are two lifting blocks 9, which are respectively fixed to the lower ends on the left and right sides of the torsion knob protrusion 8. One of the lifting blocks 9 is threadedly sleeved on the lead screw 11. The two guide rods 12 are fixed to the left and right ends inside the torsion knob housing 7. The lifting blocks 9 are respectively slidably sleeved on the guide rods 12 on the same side. A storage battery 13 and a relay 14 are connected to the inner bottom of the torsion knob housing 7. The storage battery 13 is connected in series with the relay 14. A connecting cable 18 is connected between the relay 14 and the reversible motor 10. The upper end of the torsion knob protrusion 8 is connected to an opening and closing switch 16. The power connection end of the opening and closing switch 16 is connected to a switch cable 17 buried in the torsion knob protrusion 8. A spring cable 15 is connected between the switch cable 17 and the relay 14.

[0027] When the air guiding direction of the upper blade 5 or the lower blade 6 is adjusted through the cooperation of the torsion knob protrusion 8 and the torsion knob housing 7, since the storage battery 13 supplies power to the relay 14 and the reversible motor 10, and the opening and closing switch 16 is set to control the power supply circuit of the reversible motor 10, by pressing the opening and closing switch 16 and starting the reversible motor 10, the reversible motor 10 will control the lead screw 11 to rotate forward. The lead screw 11 will drive the lifting block 9 to slide downward along the guide rod 12. Therefore, the lifting block 9 will drive the torsion knob protrusion 8 to move into the torsion knob housing 7. At this time, the torsion knob protrusion 8 will compress the spring cable 15 until the torsion knob protrusion 8 is completely received into the torsion knob housing 7, preventing the torsion knob protrusion 8 from being exposed outside for a long time, which is beneficial to ensuring the overall aesthetics of the air outlet. Moreover, the overall volume of the torsion knob becomes smaller, so the air resistance during air outlet can be reduced, thereby better improving the air outlet effect.

[0028] As Figure 1 , 3 , as shown in FIGS. 4, in this embodiment, the reversible motor 10 is fixed to the inner bottom of the torsion knob housing 7. One end of the lead screw 11 is connected to the power end of the reversible motor 10, and the other end of the lead screw 11 is rotatably connected to the inner top of the torsion knob housing 7. There are two lifting blocks 9, which are respectively fixed to the lower ends on the left and right sides of the torsion knob protrusion 8. One of the lifting blocks 9 is threadedly sleeved on the lead screw 11. The two guide rods 12 are fixed to the left and right ends inside the torsion knob housing 7. The lifting blocks 9 are respectively slidably sleeved on the guide rods 12 on the same side.

[0029] When it is necessary to move the knob projection 8 out of the knob housing 7 for use, the forward and reverse motor 10 is controlled to work through the opening and closing switch 16, and the forward and reverse motor 10 controls the screw rod 11 to reverse. The screw rod 11 drives the lifting block 9 to move upward along the guide rod 12 until the lifting block 9 pushes the knob projection 8 out of the knob housing 7. At this time, it is convenient to control the air guiding direction of the upper blade 5 or the lower blade 6 through the knob projection 8, and the operation is convenient.
