Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning outlets, and more particularly to a concealed automobile air-conditioning outlet assembly. Background Art

[0002] For a long time, the wind direction adjustment method of the air outlet of the car air conditioner mainly relies on manual operation or electric blade adjustment mechanism. In the manual control mode, the driver and passengers need to manually turn the blades of the air outlet to change the air outlet direction. This method is not only inconvenient to operate, but also has limited adjustment accuracy. Although the electric blade adjustment has improved the convenience to a certain extent, it has not essentially gotten rid of the inherent mode of traditional blade adjustment.

[0003] The blade structure design of the traditional automobile air-conditioning outlet is relatively simple. Usually, in the horizontal direction, the blade can rotate within a certain angle range to adjust the left and right wind direction; in the vertical direction, the upper and lower air outlet angles are also changed by rotating the blades. However, this blade adjustment method has many disadvantages. On the one hand, the adjustment range in the vertical direction is extremely limited. Actual use feedback shows that even if the blades are adjusted to the highest or lowest position, it is still difficult for the air outlet direction to accurately avoid the facial area of ​​the driver and passengers. Taking the normal sitting posture of adult drivers and passengers as an example, when the air outlet blades are adjusted to the vertical downward extreme angle, the airflow will still blow to the face, which not only affects the driving experience, but also may have adverse effects on health if it blows directly to the face for a long time. On the other hand, when the air outlet is blocked, the problem of a sharp decrease in air volume will be faced. Because after the traditional air outlet blades are blocked, the cross-sectional area of ​​the air duct is greatly reduced, which significantly reduces the air volume output of the air conditioning system. The reduced air volume will slow down the temperature adjustment speed in the car and cannot meet the needs of drivers and passengers for rapid temperature adjustment in the car. In view of this, we propose a hidden automobile air-conditioning outlet assembly. Summary of the invention

[0012] Preferably, the interior of the elliptical shell is divided into a first chamber, a second chamber and a third chamber by a partition, the first chamber is located at one end of the elliptical shell, the third chamber is located at the other end of the elliptical shell, and the second chamber is located between the first chamber and the third chamber.

[0013] Preferably, the input pipe and the output pipe are located on the outer wall of the second chamber and are provided with a plurality of through holes at equal intervals in a circular shape.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves the existing automobile air-conditioning outlet assembly by arranging a first linear air outlet at the bottom of the instrument panel and a second linear air outlet at the top of the storage box. Since the air outlet direction of the first linear air outlet is inclined downward and the air outlet direction of the second linear air outlet is vertically upward, the air outlet of the first linear air outlet intersects with the air outlet of the second linear air outlet. The air outlet volume of the first linear air outlet and the second linear air outlet is adjusted by controlling the output power of the air-conditioning fan. When the air outlet volume of the first linear air outlet is greater than the air outlet volume of the second linear air outlet, the wind direction facing the passenger compartment is in a downward pressure shape. When the air outlet volume of the second linear air outlet is greater than the air outlet volume of the first linear air outlet, the wind direction facing the passenger compartment is in an upward shape. The present invention solves the problem that the traditional automobile air-conditioning outlet is affected by the installation height and it is difficult to achieve comprehensive and accurate wind direction adjustment in the vertical direction, and achieves comprehensive and flexible vertical wind direction adjustment.

[0016] 2. The cold air or warm air generated by the air-conditioning fan of the present invention enters the input pipe from the side air duct and the central air duct, and then enters the elliptical shell. Since the space of the elliptical shell is much larger than that of the input pipe, the flow velocity of the airflow decreases after entering, and the kinetic energy is converted into static pressure energy, thereby reducing the noise generated by the impact of high-speed airflow. For example, the original high-speed airflow has a faster speed in the input pipe, but after entering the elliptical shell, the speed drops significantly, just like a turbulent water flow entering a wide lake, the water flow speed slows down, and the impact sound also decreases accordingly.

[0017] 3. The third chamber and the first chamber in the present invention are connected by a connecting pipe, forming a structure similar to a resonance chamber. Part of the air volume is injected into the third chamber from the input pipe, and then enters the first chamber through the connecting pipe. When the airflow flows in these two chambers and the connecting pipe, sound waves of a specific frequency will induce resonance of the air in the chamber. During the resonance process, the sound energy is converted into other forms of energy such as heat energy and consumed, thereby achieving a sound-absorbing effect.

[0018] 4. The present invention also increases exhaust resistance by designing a tortuous exhaust path, reduces airflow speed and hinders noise propagation. In the present invention, the airflow enters from the input pipe, passes through the third chamber, the connecting pipe, the first chamber, and is finally output through the output pipe. This process forms a tortuous air duct. The airflow flows in this tortuous air duct and constantly changes direction. Not only does the speed further decrease, but the noise is constantly reflected and absorbed during the propagation process. For example, when noise propagates in the air duct, it encounters the chamber wall and the turning point of the pipe, just like light encounters a reflective surface, and reflection will occur. During multiple reflections, the noise energy gradually weakens, thereby achieving noise reduction.

[0019] 5. In the present invention, several cone tubes are arranged inside the input pipe, the connecting pipe and the output pipe. The cone tube in the middle section is sleeved with a suppression tube. The wind enters through the small end of the cone tube. Due to the cone-shaped internal shape of the cone tube, the wind entering rebounds after diffusion inside and continues to be transmitted. The rebounded wind collides and interferes with the subsequent wind entering, disrupting the original orderly flow of the wind, so that the energy of the airflow is offset and consumed inside. Part of the wind overflows from the inside through the long hole opened on the cone tube, flows through the curved groove opened on the outer wall of the suppression tube, and returns to the original path through the long hole on the cone tube at the other end. When the wind flows in the curved groove, the path becomes tortuous and the flow rate is further reduced. At the same time, when the wind flows in the curved groove, it constantly collides and reflects with the wall of the curved groove, and its energy is gradually consumed in this process. Moreover, the flow of wind in the curved groove will also interfere with the wind overflowing from the long hole, making the flow of wind more chaotic, further reducing noise. The present invention is provided with a double noise suppression channel, which further improves the NVH level. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] like Figures 1 to 14 As shown, the present invention relates to a hidden automobile air-conditioning outlet assembly, comprising an instrument panel 1, a storage box 2 is provided at the bottom of the instrument panel 1, a first linear air outlet 3 is provided at the bottom of the instrument panel 1, a second linear air outlet 4 is provided at the top of the storage box 2, an air duct assembly 5 is connected to the input ends of the first linear air outlet 3 and the second linear air outlet 4, an input end of the air duct assembly 5 is connected to an air-conditioning fan, and a wind noise suppression assembly 6 is provided inside the air duct assembly 5; The first linear air outlet 3 is arranged in a horizontal direction, and a flat air outlet 302 is provided at the air outlet end of the first linear air outlet 3. The inner cavity of the flat air outlet 302 is inclined. The inclined inner cavity of the flat air outlet 302 causes the air outlet direction of the first linear air outlet 3 to be inclined downward. The air outlet direction of the second linear air outlet 4 is vertically upward; The air outlet of the first linear air outlet 3 intersects with the air outlet of the second linear air outlet 4. The air outlet volume of the first linear air outlet 3 and the second linear air outlet 4 is adjusted by controlling the output power of the air-conditioning fan at the input end of the air duct assembly 5. When the air outlet volume of the first linear air outlet 3 is greater than the air outlet volume of the second linear air outlet 4, the wind direction facing the passenger compartment is downward. When the air outlet volume of the second linear air outlet 4 is greater than the air outlet volume of the first linear air outlet 3, the wind direction facing the passenger compartment is upward.

[0036] The present invention improves the existing automobile air-conditioning outlet assembly by arranging a first linear air outlet 3 at the bottom of an instrument panel 1 and a second linear air outlet 4 at the top of a storage box 2. Since the air outlet direction of the first linear air outlet 3 is inclined downward and the air outlet direction of the second linear air outlet 4 is vertically upward, the air outlet of the first linear air outlet 3 intersects with the air outlet of the second linear air outlet 4. The air outlet volume of the first linear air outlet 3 and the second linear air outlet 4 is adjusted by controlling the output power of the air-conditioning fan. When the air outlet volume of the first linear air outlet 3 is greater than that of the second linear air outlet 4, the wind direction facing the passenger compartment is downward. When the air outlet volume of the second linear air outlet 4 is greater than that of the first linear air outlet 3, the wind direction facing the passenger compartment is upward. The present invention solves the problem that the traditional automobile air-conditioning outlet is affected by the installation height and it is difficult to achieve comprehensive and accurate wind direction adjustment in the vertical direction, and achieves comprehensive and flexible vertical wind direction adjustment.

[0037] In the embodiment of the present invention, dynamic control blades 301 are arranged at equal intervals in the horizontal direction on the first linear air outlet 3, and the dynamic control blades 301 control the left and right directions of the air outlet of the first linear air outlet 3; The air outlet end of the second linear air outlet 4 is horizontally provided with blocking bars 401 at equal intervals.

[0038] The dynamic control blade 301 and the blocking bar 401 used in the present invention are prior art. The dynamic control blade 301 has the function of regulating the left and right wind directions, and the blocking bar 401 is used to prevent foreign objects from falling into the second linear air outlet 4, which would affect the air outlet.

[0039] In the embodiment of the present invention, the air duct assembly 5 includes a central air duct 501, a side air duct 502 and a glass air duct 503. The input ends of the central air duct 501, the side air duct 502 and the glass air duct 503 are all connected to the air conditioning fan. The central air duct 501 has one air inlet and two air outlets. The wind noise suppression assembly 6 is connected to the two air outlets of the central air duct 501, and the air inlet and air outlet of the side air duct 502 are each provided with one. The wind noise suppression assembly 6 is also connected to the air outlet of the side air duct 502. The input ends of the central air duct 501, the side air duct 502 and the glass air duct 503 in the present invention are all connected to the air conditioning fan. The cold air or warm air generated by the air conditioner fan in the present invention enters from the central air duct 501, the side air duct 502 and the glass air duct 503 of the air duct assembly 5, the central air duct 501 and the side air duct 502 are input into the wind noise suppression assembly 6, and the glass air duct 503 is directly aimed at the inner wall of the front windshield of the car for defogger.

[0040] In the embodiment of the present invention, the input end of the wind noise suppression component 6 is connected to the output ends of the central air duct 501 and the side air duct 502 , and the output end of the wind noise suppression component 6 is connected to the input ends of the first linear air outlet 3 and the second linear air outlet 4 .

[0041] In an embodiment of the present invention, the wind noise suppression component 6 includes a first shell group 601, a second shell group 602, a noise reduction unit 603 and a suppression unit 604, the input end of the first shell group 601 is connected to the output end of the side air duct 502, the output end of the first shell group 601 is connected to the input end of the first linear air outlet 3, the input end of the second shell group 602 is connected to the output end of the central air duct 501, the output end of the second shell group 602 is connected to the input end of the second linear air outlet 4, the noise reduction unit 603 is arranged inside the first shell group 601 and the second shell group 602, and the suppression unit 604 is arranged inside the noise reduction unit 603.

[0042] In an embodiment of the present invention, the first shell group 601 includes an output end of the first shell group 601 that is adapted in shape to the first linear air outlet 3, and an output end of the second shell group 602 that is adapted in shape to the second linear air outlet 4. The output end of the first shell group 601 is oriented horizontally toward the passenger compartment, and the output end of the second shell group 602 is oriented vertically upward.

[0043] The cold air or warm air generated by the air conditioner fan in the present invention is input into the first shell group 601 from the side duct 502 of the duct assembly 5, and input into the second shell group 602 from the central duct 501, and then input into the first linear air outlet 3 and the second linear air outlet 4 through the first shell group 601 and the second shell group 602 to achieve blowing.

[0044] As another embodiment of the present invention, the noise reduction unit 603 includes an elliptical shell 6031, an input pipe 6032, a connecting pipe 6033 and an output pipe 6034. The elliptical shell 6031 is arranged inside the first shell group 601 and the second shell group 602. The input pipe 6032, the connecting pipe 6033 and the output pipe 6034 are all inserted into the elliptical shell 6031. The suppression unit 604 is arranged inside the input pipe 6032, the connecting pipe 6033 and the output pipe 6034.

[0045] The cold air or warm air generated by the air-conditioning fan of the present invention enters the input pipe 6032 from the side air duct 502 and the central air duct 501, and then enters the elliptical shell 6031. Since the space of the elliptical shell 6031 is much larger than that of the input pipe 6032, the flow velocity of the air flow decreases after entering, and the kinetic energy is converted into static pressure energy, thereby reducing the noise generated by the impact of high-speed air flow. For example, the original high-speed air flow has a faster speed in the input pipe 6032, but after entering the elliptical shell 6031, the speed drops significantly, just like a turbulent water flow entering a wide lake, the water flow speed slows down, and the impact sound also decreases accordingly.

[0046] The third chamber 6037 and the first chamber 6035 in the present invention are connected by a connecting pipe 6033, forming a structure similar to a resonance chamber. Part of the air volume is injected into the third chamber 6037 from the input pipe 6032, and then enters the first chamber 6035 through the connecting pipe 6033. When the air flow flows in these two chambers and the connecting pipe, sound waves of a specific frequency will induce resonance of the air in the chamber. During the resonance process, the sound energy is converted into other forms of energy such as heat energy and consumed, thereby achieving a sound-absorbing effect.

[0047] The present invention also increases exhaust resistance by designing a tortuous exhaust path, reduces airflow speed and hinders noise propagation. In the present invention, the airflow enters from the input pipe 6032, passes through the third chamber 6037, the connecting pipe 6033, and the first chamber 6035, and is finally output through the output pipe 6034. This process forms a tortuous air duct. The airflow flows in this tortuous air duct and constantly changes direction. Not only is the speed further reduced, but the noise is constantly reflected and absorbed during the propagation process. For example, when noise propagates in the air duct, it encounters the chamber wall and the pipe bend, just like light encountering a reflective surface, and reflection will occur. During multiple reflections, the noise energy gradually weakens, thereby achieving noise reduction.

[0048] As another embodiment of the present invention, the interior of the elliptical shell 6031 is divided into a first chamber 6035, a second chamber 6036 and a third chamber 6037 by a partition 6039. The first chamber 6035 is located at one end of the elliptical shell 6031, the third chamber 6037 is located at the other end of the elliptical shell 6031, and the second chamber 6036 is located between the first chamber 6035 and the third chamber 6037.

[0049] As another embodiment of the present invention, the input pipe 6032 and the output pipe 6034 are located on the outer wall of the second chamber 6036 and are provided with a plurality of through holes 6038 in a circular shape and at equal intervals. The air intake route is to be injected from the input pipe 6032, and part of the air volume is injected into the third chamber 6037 through the input pipe 6032, enter the connecting pipe 6033 through the third chamber 6037, enter the first chamber 6035 through the connecting pipe 6033, enter the output pipe 6034 through the first chamber 6035, and be output through the output pipe 6034; Another part of the air volume enters the second chamber 6036 through the through hole 6038 of the input pipe 6032 , and is directly output through the second chamber 6036 through the through hole 6038 of the output pipe 6034 .

[0050] As another embodiment of the present invention, the suppression unit 604 includes a conical tube 6041, a suppression tube 6042, a long hole 6043 and a curved groove 6044. Several conical tubes 6041 are connected in sequence inside the input tube 6032, the connecting tube 6033 and the output tube 6034. The suppression tube 6042 is sleeved on the outer wall of the conical tube 6041. The long holes 6043 are arranged in a circular shape with equal intervals on the conical tube 6041 near the end, and the curved grooves 6044 are arranged in a circular shape with equal intervals on the outer wall of the suppression tube 6042.

[0051] In the present invention, a plurality of cone tubes 6041 are arranged inside the input tube 6032, the connecting tube 6033 and the output tube 6034. The middle cone tube 6041 is sleeved with a suppression tube 6042. The wind enters through the small end of the cone tube 6041. Since the cone tube 6041 has a conical internal shape, the wind entering rebounds after diffusion inside and continues to be transmitted. The rebounded wind collides and interferes with the subsequent wind entering, disrupting the original orderly flow of the wind, so that the energy of the airflow is offset and consumed inside. Part of the wind overflows from the inside through the long hole 6043 opened on the cone tube 6041, flows through the curved groove 6044 opened on the outer wall of the suppression tube 6042, and returns to the original path through the long hole 6043 on the cone tube 6041 at the other end. When the wind flows in the curved groove 6044, the path becomes tortuous and the flow rate is further reduced. At the same time, when the wind flows in the curved groove 6044, it constantly collides and reflects with the wall surface of the curved groove 6044, and its energy is gradually consumed in this process. Moreover, the flow of wind in the curved groove 6044 will also interfere with the wind overflowing from the long hole 6043, making the flow of wind more turbulent, further reducing noise. The present invention is provided with a double noise suppression channel, which further improves the NVH level.

[0052] Working principle: This embodiment provides a hidden automobile air-conditioning outlet assembly. When in use, the air-conditioning system is first used for cooling or heating, and the warm air or cold air is transmitted to the air duct assembly 5 through the air-conditioning fan, and then transmitted to the first linear air vent 3 and the second linear air vent 4 through the air duct assembly 5. The air volume of the first linear air vent 3 and the second linear air vent 4 is adjusted by controlling the output power of the air-conditioning fan. When the air volume of the first linear air vent 3 is greater than that of the second linear air vent 4, the wind direction facing the passenger compartment is downward, and when the air volume of the second linear air vent 4 is greater than that of the first linear air vent 3, the wind direction facing the passenger compartment is upward, thereby realizing large-area adjustment of vertical wind direction. The air intake route of the noise reduction unit 603 is injected from the input pipe 6032. Part of the air volume is injected into the third chamber 6037 through the input pipe 6032, enters the connecting pipe 6033 through the third chamber 6037, enters the first chamber 6035 through the connecting pipe 6033, enters the output pipe 6034 through the first chamber 6035, and is output through the output pipe 6034; another part of the air volume enters the second chamber 6036 through the through hole 6038 of the input pipe 6032, and is directly output through the through hole 6038 of the output pipe 6034 through the second chamber 6036; The air inlet route of the suppression unit 604 is that the air enters through the small end of the cone tube 6041. Since the cone tube 6041 has a conical internal shape, the incoming air rebounds and continues to be transmitted after diffusion inside. Part of the air overflows from the inside through the long hole 6043 opened on the cone tube 6041, flows through the curved groove 6044 opened on the outer wall of the suppression tube 6042, and returns to the original path through the long hole 6043 on the cone tube 6041 at the other end.

[0053] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
