[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.

[0026] In the claims, specification and the above drawings of the present utility model, the terms "front" and "rear" are the same as the front-rear direction of the vehicle body, and the terms "left" and "right" are the same as the left-right direction of the vehicle body. The remaining directional words, unless otherwise clearly defined, such as "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, so they cannot be understood as limiting the specific protection scope of the present invention.

[0027] As people's quality of life improves, their requirements for car comfort are also getting higher and higher. However, the car is stuffy in the summer, and the temperature rises slowly after turning on the air conditioner. In the winter, when the car is outdoors, the temperature inside the car cannot rise in a short time, causing trouble to passengers.

[0028] In order to meet the needs of drivers and passengers for in-car temperature control, multiple air-conditioning outlets are currently installed on the dashboard. However, with the increase in vehicle functions, the number of components installed on the dashboard is increasing, and the shape is getting larger and larger, which squeezes and limits the space for the air-conditioning outlets. If the area of ​​the outlet is too small, it will cause problems such as wind noise, high wind speed, and air volume loss, which will affect the rapid response of in-car temperature control and the comfort of drivers and passengers.

[0029] Since a center speaker is provided in the middle of the dashboard, the surface of the center speaker in the middle of the dashboard will be covered with a center speaker mask with a porous structure. If the sound-permeable holes on the center speaker mask are used as additional air outlets, it is not necessary to occupy the space on the dashboard, and it is not necessary to change the original shape of the dashboard. Therefore, the center air outlet assembly provided by the utility model cleverly utilizes the sound-permeable holes of the center speaker mask as the air outlet, increases the area of ​​the air outlet without occupying the space on the dashboard, and improves the speed of temperature adjustment in the car.

[0030] Please also read Figures 1 to 6 The central air outlet assembly provided by the utility model is now described. The central air outlet assembly includes a central speaker mask 1 and an air outlet duct 5, which is arranged at the periphery of the central speaker; the air inlet of the air outlet duct 5 is connected to the air conditioning system in the vehicle, the air outlet 51 of the air outlet duct 5 is connected to the central speaker mask 1, and part of the sound-transmitting holes 12 on the central speaker mask 1 constitute the air outlet holes 13 of the air outlet duct 5.

[0031] The center air outlet assembly provided by the utility model is provided with an air outlet duct 5 on the periphery of the center speaker, and the sound-transmitting hole 12 on the center speaker mask 1 is directly used as the air outlet 13. There is no need to additionally provide the air outlet 13 on the instrument panel, and other space of the instrument panel is not occupied. The air outlet area of ​​the air outlet 51 in the car can be increased, which is conducive to quickly increasing or decreasing the temperature in the car, thereby improving the experience of the driver and passengers.

[0032] The central air outlet assembly provided by the utility model utilizes the central speaker mask 1 with a large opening area as the air outlet 13, which can meet the sound transmission requirements of the speaker and the air outlet requirements of the air outlet 51.

[0033] In order to avoid affecting the visual effect of the appearance, a sound-permeable cotton 2 with good air permeability is set between the inner side of the center speaker mask 1 and the air outlet duct 5 to prevent the internal structure from leaking out and affecting the appearance; at the same time, the sound-permeable cotton 2 also has the effect of sound absorption and noise reduction and reducing wind speed to enhance the comfort experience of the air outlet. On this basis, the sound-permeable cotton 2 can be made of cotton felt, sponge, felt and other materials with good air permeability.

[0034] In order to enhance the auditory experience of the driver and passengers, the installation position of the center speaker mask 1 is generally towards the ear position of the passenger's head. Therefore, the air outlet area of ​​the added air outlet 13 is also in the passenger's head area, providing a comfortable temperature environment for the passenger.

[0035] In some embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, the air outlet duct 5 is a variable diameter bend, which has an air inlet section 56, an arc-shaped guide section 55 and an expanded outlet section 54 in sequence. The arc-shaped guide section 55 makes the angle between the air inlet direction of the air inlet and the air outlet direction of the air outlet 51 an acute angle; the radius of the expanded outlet section 54 is greater than the radius of the air inlet section 56. Since the air outlet 51 of the in-vehicle air conditioner is designed to avoid noise and excessive wind speed causing discomfort to the human body, the air outlet duct 5 is designed as a variable diameter bend. On the one hand, through the curved design of the arc-shaped guide section 55, the wind energy changes direction when encountering the curved part to achieve weakening and attenuation, thereby reducing the wind speed; on the other hand, the enlarged diameter of the air outlet 51 can also reduce the wind speed and reduce the noise.

[0036] The specific principle is as follows: Since wind speed is closely related to noise, when the air flow speed doubles, the sound power level increases by 15dB. According to the relationship between wind flow, wind speed and cross-sectional area, flow = wind speed × cross-sectional area, that is, the flow and wind speed are inversely proportional. In other words, when the cross-sectional area remains unchanged, the greater the wind speed, the greater the flow; the smaller the wind speed, the smaller the flow. Similarly, when the wind speed remains unchanged, the larger the cross-sectional area, the greater the flow; the smaller the cross-sectional area, the smaller the flow. Therefore, by expanding the air outlet 51, the air outlet speed is reduced at the same flow rate, which can not only improve the softness of the air outlet, but also reduce noise. Among them, flow refers to the volume of fluid (gas or liquid) passing through a cross section per unit time, and wind speed refers to the speed of gas flow.

[0037] Optionally, the angle between the air inlet direction and the air outlet direction of the air outlet duct 5 is greater than 75° (for example, the angle is 75°, 80°, 85°, etc.) to guide the airflow to change direction smoothly and gradually. If the angle is too small, it will generate greater noise and affect the comfort in the car.

[0038] In some embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, the curvature radius of the outer wall of the arc-shaped guide section 55 is greater than the curvature radius of the inner wall thereof, forming a vortex weakening section where the outer wall expands outward. The outer wall of the arc-shaped guide section 55 is designed to expand outward at a larger angle, so that the wind speed has a larger space to swirl and weaken here, and then the wind is discharged through the expanded air outlet 51, the softness of the air outlet will be significantly improved, the noise will be significantly reduced, and the comfort of the passengers in the vehicle will be improved.

[0039] Furthermore, the outer wall of the arc-shaped guide section 55 adopts a large rounded transition of R45mm, which can make the airflows offset each other in the expanded space, reduce the flow rate, prevent the airflow impact sound, and improve the comfort of the passengers in the car. For example, the radius R of the outer wall of the arc-shaped guide section 55 can be 45mm, 50mm, 55mm, 60mm, etc.

[0040] In some embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, the inner diameter of the air outlet duct 5 gradually increases from the air inlet to the air outlet 51. By gradually increasing the inner diameter of the air outlet duct 5, it is avoided that the drop in wind speed is too large, which causes a problem of high noise.

[0041] Under the premise of increasing the air outlet area, the comfort and quietness of the air outlet are also the key points that need to be paid attention to. Therefore, the present application makes multi-faceted improvements to the structure and shape of the air outlet duct 5 to achieve a better comfort experience effect. Therefore, in order to guide the air outlet direction and make the air outlet direction face the side that is beneficial to the human body, in this embodiment, a guide blade 52 is provided on the air outlet 51 of the air outlet duct 5, and the air guide surface of the guide blade 52 is parallel to the air outlet direction of the air outlet 51.

[0042] On this basis, a plurality of guide blades 52 are arranged in parallel at the air outlet 51 to guide the air outlet direction and control the wind speed so as to achieve the purpose of comfortable air outlet experience.

[0043] In some embodiments, see Figure 6 As shown, a muffler fillet 521 is provided at one end of the guide blade 52 away from the air outlet 51, and a muffler slope 522 is provided at one end of the guide blade 52 facing the air outlet 51. The muffler fillet 521 is provided to guide the airflow to smoothly transition and turn, and reduce the noise of the airflow. When the airflow encounters a sharp corner, it will generate a lot of noise, affecting comfort; the muffler slope 522 provided at the air outlet can further expand the effective air outlet area at the outlet, thereby reducing the wind speed, which is also conducive to the comfortable experience of air outlet.

[0044] The air inlet of the air outlet duct 5 needs to be connected to the air outlet 51 of the air conditioning system in the vehicle. In order to ensure the sealing of the connection part and prevent air leakage, a sealing gasket 4 is used to press the connection between the air outlet duct 5 and the air conditioner to improve the air tightness. The sealing gasket 4 can be made of sponge, rubber pad, silicone pad or other sealing parts.

[0045] Regarding the number of air outlet ducts 5, one air outlet duct 5 may be arranged according to the design air outlet requirements, or two or three air outlet ducts 5 may be arranged on concentric circles with the center of the sound-permeable opening 31 of the center speaker as the center of the circle; regarding the fixing method of the air outlet duct 5, a single one may be directly connected to the center speaker mask 1, or it may be riveted, screwed or welded to the center speaker mask 1. If welding is adopted, a welding column 11 may be integrally injection molded on the center speaker mask 1, and the welding column 11 may pass through the reserved hole on the air duct bracket 3, and then welding is performed to improve the firmness of the welding fixation.

[0046] When multiple air outlet ducts 5 are provided, the multiple air outlet ducts 5 can be integrally formed or fixed on the duct bracket 3, and the duct bracket 3 is then fixed together with the center speaker mask 1. Therefore, the present application also includes the duct bracket 3 fixed to the center speaker mask 1, see Figure 1 , Figure 5 and Figure 6 As shown, a sound-transmitting port 31 is provided on the air duct bracket 3 at a position corresponding to the center speaker; and an air outlet duct 5 is provided on the air duct bracket 3 symmetrically along the center line of the sound-transmitting port 31. In this embodiment, a plurality of air outlet ducts 5 are provided to increase the speed of temperature control in the vehicle. They can also be provided symmetrically up and down and evenly arranged along the sound-transmitting port 31.

[0047] In some embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, the air outlet duct 5 includes a first air duct portion 58 and a second air duct portion 59 which are separately arranged, and the air duct bracket 3 is also divided into a first sub-bracket 34 and a second sub-bracket 35. The first air duct portion 58 is fixed on the first sub-bracket 34, and the second air duct portion 59 is connected with the first air duct portion 58 to form a complete air outlet duct 5. In this embodiment, the air outlet duct 5 is designed to be split, so that the first air duct portion 58 can be integrally injection molded with the air duct bracket 3, and the second air duct portion 59 can be separately injection molded, and then fixed together by snap connection, thereby reducing the manufacturing cost and manufacturing difficulty. Among them, the second air duct portion 59 is provided with a second sub-bracket 35 connected with the first sub-bracket 34 at the air outlet 51, so that the air duct bracket 3 can be square or circular in shape. After the two air duct portions are connected, the air duct bracket 3 is fixed to the center speaker mask 1.

[0048] Optionally, the air duct support 3 can be separately injection molded, and after the air outlet ducts 5 are separately injection molded, each air outlet duct 5 is then fixed to the air duct support 3 by snap connection, adhesive connection or screw connection.

[0049] On this basis, a plurality of card connectors 32 and card interfaces 33 that cooperate with each other are provided between the first air duct portion 58 and the second air duct portion 59 .

[0050] See also Figure 5 and Figure 6 As shown, in order to ensure the sealing of the first air duct portion 58 and the second air duct portion 59 after docking, a radially extending rib 57 is provided at the edge where the first air duct portion 58 and the second air duct portion 59 are docked, and the rib 57 can cover the gap after the two are docked.

[0051] In some embodiments, see Figure 1 , Figure 5 and Figure 6 As shown, the air outlet 51 of the first air duct portion 58 is provided with a snap-in groove 53, and the air outlet 51 of the second air duct portion 59 is provided with a guide blade 52, and the guide blade 52 can be inserted into the snap-in groove 53. When the first air duct portion 58 and the second air duct portion 59 are snap-fitted, the guide blade 52 is inserted into the snap-in groove 53 of the first air duct portion 58, and the assembly is simple and convenient.

[0052] Optionally, the air guiding direction of the guide blade 52 can be adjusted. For example, both ends of the guide blade 52 are rotatably connected to the air outlet duct 5, and a rotating motor is set at one end to drive the guide blade 52 to rotate counterclockwise or clockwise by a certain angle, thereby achieving the adjustment of the air outlet direction.

[0053] With the intelligence of the entire vehicle, the air volume of the central air outlet 51 and the air guiding direction of the guide blades 52 can also be intelligently adjusted. Specifically, an electric valve (not shown in the figure) is respectively arranged in each air outlet duct 5, and a switch button for controlling the opening and closing of the electric valve and a wind direction adjustment button for the rotation of the guide blades 52 are installed on the display screen integrated on the dashboard. The opening and closing of the air outlet can be controlled by operating the switch button on the display screen, and the central air outlet 51 can be closed by closing the electric valve; after the temperature inside the vehicle drops to a certain temperature, the central air outlet duct 5 can be closed, and the subsequent cooling can be carried out through the air outlet 51 in front of the dashboard.

[0054] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
