Description

Technical Field

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

[0002] For a long time, the air direction adjustment method of automotive air-conditioning air outlets mainly relies on manual operation or an electric vane adjustment mechanism. In the manual control mode, the driver and passengers need to manually move the vanes of the air outlet to change the air direction. This method is not only inconvenient to operate but also has limited adjustment accuracy. Although the electric vane adjustment improves convenience to a certain extent, it still essentially follows the inherent mode of traditional vane adjustment.

[0003] In a traditional automotive air-conditioning air outlet, the vane structure design is relatively simple. Generally, in the horizontal direction, the vanes can rotate within a certain angle range to achieve left-right air direction adjustment; in the vertical direction, the air outlet angle is also changed by the rotation of the vanes. However, this vane adjustment method has many drawbacks. On the one hand, the adjustment range in the vertical direction is extremely limited. Practical use feedback shows that even when the vanes are adjusted to the highest or lowest position, the air outlet direction is still difficult 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 vanes are adjusted to the vertical downward limit angle, the air flow still blows on the face, which not only affects the driving and riding experience but may also have an adverse impact on health if blown directly on the face for a long time. On the other hand, when blocking the air outlet, there will be a problem of a sharp reduction in air volume. Because after the traditional air outlet vanes are blocked, the cross-sectional area of the air duct is greatly reduced, resulting in a significant reduction in the air volume output of the air-conditioning system. The reduction in air volume will slow down the speed of adjusting the vehicle interior temperature and cannot meet the driver and passengers' demand for quickly adjusting the vehicle interior temperature. In view of this, we propose a hidden automotive air-conditioning air outlet assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a hidden automotive air-conditioning air outlet assembly to solve the technical problem of limited vertical air direction adjustment caused by the use of a hidden air outlet in existing automotive air conditioners.

By controlling the output power of the air-conditioning fan at the input end of the air duct assembly, the air output of the first linear air outlet and the second linear air outlet is adjusted. When the air output of the first linear air outlet is greater than that of the second linear air outlet, the wind direction facing the passenger compartment is in a downward pressing state. When the air output of the second linear air outlet is greater than that of the first linear air outlet, the wind direction facing the passenger compartment is in an upward rising state.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention improves the existing automotive air-conditioning outlet assembly. By providing a first linear air outlet at the bottom end of the instrument panel and a second linear air outlet at the top end 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 from the first linear air outlet intersects with the air from the second linear air outlet. By controlling the output power of the air-conditioning blower and adjusting the air volume of the first linear air outlet and the second linear air outlet, when the air volume of the first linear air outlet is greater than that of the second linear air outlet, the wind direction facing the passenger compartment is in a downward pressing state; when the air volume of the second linear air outlet is greater than that of the first linear air outlet, the wind direction facing the passenger compartment is in an upward rising state. The present invention solves the problem that the traditional automotive 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 realizes comprehensive and flexible vertical wind direction adjustment.

[0022] 2. The cold air or warm air generated by the air-conditioning blower of the present invention enters the input pipe from the side air duct and the central air duct, and then enters the ellipsoidal housing. Since the space of the ellipsoidal housing is much larger than that of the input pipe, 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 the high-speed air flow. For example, the air flow that originally flowed at a high speed in the input pipe has a relatively high speed, but after entering the ellipsoidal housing, the speed drops significantly, just like a turbulent stream flowing into a wide lake, the flow velocity slows down, and the impact sound also decreases accordingly.

[0023] 3. The third chamber and the first chamber in the present invention are connected by a communication 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 communication pipe. When the air flow flows in these two chambers and the communication pipe, sound waves of a specific frequency will cause the 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 the effect of noise reduction.

[0024] 4. The present invention also increases the exhaust resistance by designing a tortuous exhaust path, reduces the air flow velocity and hinders the propagation of noise. In the present invention, the air flow enters from the input pipe, passes through the third chamber, the communication pipe, and the first chamber in sequence, and finally is output through the output pipe. This process forms a tortuous air duct. The air flow flows in this tortuous air duct and continuously changes direction. Not only does the speed further decrease, but the noise is continuously reflected and absorbed during the propagation process. For example, when the noise propagates in the air duct and encounters the chamber wall surface and the pipe turning point, it will be reflected just like light encountering a reflecting surface. During the multiple reflection processes, the noise energy gradually weakens, thereby achieving noise reduction.

[0025] 5. In the present invention, several conical tubes are arranged inside the input tube, the connecting tube and the output tube. A suppression tube is sleeved on the conical tube in the middle section. The air flow enters through the small end of the conical tube. Due to the conical internal shape of the conical tube, the entering air flow diffuses and rebounds inside and then continues to be transmitted. The rebounding air flow collides and interferes with the subsequent entering air flow, disrupting the original orderly flow of the air flow, and causing the energy of the air flow to cancel and consume each other inside. Part of the air flow overflows from the long holes opened on the conical tube and circulates through the curved grooves opened on the outer wall of the suppression tube, and returns to the original path through the long holes on the conical tube at the other end. When the air flow circulates in the curved grooves, the path becomes tortuous and the flow rate further decreases. At the same time, when the air flow flows in the curved grooves, it continuously collides and reflects with the wall surface of the curved grooves, and its energy gradually consumes in this process. Moreover, the flow of the air flow in the curved grooves will also interfere with the air flow overflowing from the long holes, making the flow of the air flow more disordered and further reducing the noise. The present invention is provided with a double noise suppression channel, further improving the NVH level. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The first linear air outlet 3 is arranged horizontally, 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, and 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;

[0049] The air outlet direction of the second linear air outlet 4 is vertically upward;

[0050] The air output of the first linear air outlet 3 intersects with the air output of the second linear air outlet 4. By controlling the output power of the air conditioner blower at the input end of the air duct assembly 5, the air output of the first linear air outlet 3 and the second linear air outlet 4 is adjusted. When the air output 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 in a downward pressing state. When the air output 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 in an upward rising state.

[0051] The present invention improves the existing automotive air conditioner air outlet assembly. By providing a first linear air outlet 3 at the bottom end of the instrument panel 1 and a second linear air outlet 4 at the top end of the storage box 2. Since the air output direction of the first linear air outlet 3 is inclined downward and the air output direction of the second linear air outlet 4 is vertically upward, the air output of the first linear air outlet 3 intersects with the air output of the second linear air outlet 4. By controlling the output power of the air conditioner blower, the air output of the first linear air outlet 3 and the second linear air outlet 4 is adjusted. When the air output 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 in a downward pressing state. When the air output 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 in an upward rising state. The present invention solves the problem that the traditional automotive air conditioner air outlet is affected by the installation height and it is difficult to achieve comprehensive and accurate wind direction adjustment in the vertical direction, and realizes comprehensive and flexible vertical wind direction adjustment.

[0054] The dynamic control blades 301 and the blocking strips 401 adopted in the present invention are prior arts. The dynamic control blades 301 have the function of regulating the left - right wind direction, and the blocking strips 401 are to prevent foreign objects from falling into the second linear air outlet 4, which may affect the air output.

[0055] In an embodiment of the present invention, the air duct assembly 5 includes a central air duct 501, side air ducts 502, and a glass air duct 503. The input ends of the central air duct 501, side air ducts 502, and glass air duct 503 are all connected to an air-conditioning blower. 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. The side air ducts 502 each have one air inlet and one air outlet, and the wind noise suppression assembly 6 is also connected to the air outlet of the side air duct 502. In the present invention, the input ends of the central air duct 501, side air ducts 502, and glass air duct 503 are all connected to an air-conditioning blower. The cold air or warm air generated by the air-conditioning blower in the present invention enters through the central air duct 501, side air ducts 502, and glass air duct 503 of the air duct assembly 5. The central air duct 501 and side air ducts 502 input the wind noise suppression assembly 6, and the glass air duct 503 directly blows against the inner wall of the front windshield of the vehicle for defogging.

[0056] In an embodiment of the present invention, the input end of the wind noise suppression assembly 6 is connected to the output ends of the central air duct 501 and side air ducts 502, and the output end of the wind noise suppression assembly 6 is connected to the input ends of the first linear air outlet 3 and the second linear air outlet 4.

[0057] In an embodiment of the present invention, the wind noise suppression assembly 6 includes a first housing group 601, a second housing group 602, a noise reduction unit 603, and a suppression unit 604. The input end of the first housing group 601 is connected to the output end of the side air duct 502, the output end of the first housing group 601 is connected to the input end of the first linear air outlet 3, the input end of the second housing group 602 is connected to the output end of the central air duct 501, the output end of the second housing group 602 is connected to the input end of the second linear air outlet 4, the noise reduction unit 603 is disposed inside the first housing group 601 and the second housing group 602, and the suppression unit 604 is disposed inside the noise reduction unit 603.

[0058] In an embodiment of the present invention, the output end of the first housing group 601 is adapted to the shape of the first linear air outlet 3, the output end of the second housing group 602 is adapted to the shape of the second linear air outlet 4, the output end of the first housing group 601 faces horizontally towards the passenger compartment, and the output end of the second housing group 602 faces vertically upwards.

[0059] In the present invention, the cold air or warm air generated by the air-conditioning blower enters the first housing group 601 from the side air duct 502 of the air duct assembly 5, enters the second housing group 602 from the central air duct 501, and then blows through the first housing group 601 and the second housing group 602 into the first linear air outlet 3 and the second linear air outlet 4.

[0060] As another embodiment of the present invention, the noise reduction unit 603 includes an ellipsoidal housing 6031, an input pipe 6032, a connecting pipe 6033, and an output pipe 6034. The ellipsoidal housing 6031 is disposed inside the first housing group 601 and the second housing group 602. The input pipe 6032, the connecting pipe 6033, and the output pipe 6034 are all inserted on the ellipsoidal housing 6031. The suppression unit 604 is disposed inside the input pipe 6032, the connecting pipe 6033, and the output pipe 6034.

[0061] The cold air or warm air generated by the air conditioner 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 ellipsoidal housing 6031. Since the space of the ellipsoidal housing 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 the high-speed air flow. For example, the air flow that originally flowed at a high speed in the input pipe 6032 has a high speed, but after entering the ellipsoidal housing 6031, the speed drops significantly, just like a rapid current entering a wide lake, the flow velocity slows down, and the impact sound also decreases accordingly.

[0062] In the present invention, the third chamber 6037 and the first chamber 6035 are connected by the 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 cause the 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 the effect of noise reduction.

[0063] The present invention also increases the exhaust resistance by designing a tortuous exhaust path, reducing the air flow velocity and hindering the propagation of noise. In the present invention, the air flow enters from the input pipe 6032, passes through the third chamber 6037, the connecting pipe 6033, and the first chamber 6035 in sequence, and finally is output through the output pipe 6034. This process forms a tortuous air duct. The air flow flows in this tortuous air duct and continuously changes direction. Not only does the speed further decrease, but the noise is continuously reflected and absorbed during the propagation process. For example, when the noise propagates in the air duct and encounters the chamber wall surface and the pipe turning point, it will be reflected just like light encountering a reflecting surface. During the multiple reflection processes, the noise energy gradually weakens, thereby achieving noise reduction.

[0064] As another embodiment of the present invention, the inside of the ellipsoidal housing 6031 is separated 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 inside the ellipsoidal housing 6031, the third chamber 6037 is located at the other end inside the ellipsoidal housing 6031, and the second chamber 6036 is located between the first chamber 6035 and the third chamber 6037.

[0065] As another embodiment of the present invention, a plurality of through holes 6038 are formed at equal intervals in a ring shape on the outer wall of a part of the second chamber 6036 where the input pipe 6032 and the output pipe 6034 are located. The air inlet route is to inject from the input pipe 6032. A part of the air volume is injected into the third chamber 6037 through the input pipe 6032, enters the communication pipe 6033 through the third chamber 6037, enters the first chamber 6035 through the communication pipe 6033, enters the output pipe 6034 through the first chamber 6035, and is output through the output pipe 6034;

[0066] Another part of the air volume enters the second chamber 6036 through the through holes 6038 of the input pipe 6032 and is directly output through the through holes 6038 of the output pipe 6034 passing through the second chamber 6036.

[0067] As another embodiment of the present invention, the suppression unit 604 includes a tapered pipe 6041, a suppression pipe 6042, a long hole 6043, and a curved groove 6044. A plurality of tapered pipes 6041 are sequentially connected and arranged inside the input pipe 6032, the communication pipe 6033, and the output pipe 6034. The suppression pipe 6042 is sleeved on the outer wall of the tapered pipe 6041. The long holes 6043 are formed at equal intervals in a ring shape on the tapered pipe 6041 near the end. The curved grooves 6044 are formed at equal intervals in a ring shape on the outer wall of the suppression pipe 6042.

[0068] In the present invention, a plurality of tapered pipes 6041 are provided inside the input pipe 6032, the communication pipe 6033, and the output pipe 6034. A suppression pipe 6042 is sleeved on the tapered pipe 6041 in the middle section. The air enters through the small head end of the tapered pipe 6041. Due to the tapered internal shape of the tapered pipe 6041, the entering air diffuses and rebounds inside and continues to be transmitted. The rebounding air collides and interferes with the subsequent entering air, disrupting the original orderly flow of the air and causing the energy of the air flow to cancel and consume each other inside. A part of the air overflows from the inside through the long holes 6043 formed on the tapered pipe 6041, flows through the curved grooves 6044 formed on the outer wall of the suppression pipe 6042, and returns to the original path through the long holes 6043 on the tapered pipe 6041 at the other end. When the air flows through the curved grooves 6044, the path becomes tortuous and the flow rate is further reduced. At the same time, when the air flows in the curved grooves 6044, it continuously collides and reflects with the wall surface of the curved grooves 6044, and its energy gradually consumes in this process. Moreover, the flow of the air in the curved grooves 6044 will also interfere with the air overflowing from the long holes 6043, making the flow of the air more disordered and further reducing the noise. The present invention is provided with a double noise suppression channel, further improving the NVH level.

[0069] Working principle: This embodiment provides a concealed automotive air-conditioning outlet assembly. When in use, first, the air-conditioning system cools or heats the air. The warm or cold air is introduced into the duct assembly 5 by the air-conditioning blower, and then transmitted to the first linear air outlet 3 and the second linear air outlet 4 through the duct assembly 5. By controlling the output power of the air-conditioning blower, the air volume of the first linear air outlet 3 and the second linear air outlet 4 is adjusted. When the air 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 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, realizing large-area adjustment of the vertical wind direction.

[0070] 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 passing through the second chamber 6036.

[0071] The air intake route of the suppression unit 604 is that the air enters through the small end of the tapered pipe 6041. Due to the tapered internal shape of the tapered pipe 6041, the entering air diffuses and rebounds inside and continues to be transmitted.
