Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically, to an automotive air conditioning vent structure and an automotive. Background Technology

[0002] The air vent structure of a car's air conditioning system is an important component of the system. It is usually installed on the dashboard. Users can adjust the air vent angle and air volume by moving the upper and lower air guide blades by turning a knob, thus meeting the air blowing requirements of different passengers.

[0003] To maximize the vertical airflow angle of the air vent, two or more vertical guide vanes are typically required. This results in a larger air vent size, which affects the installation of other components on the car's dashboard and reduces the aesthetics of the car's interior. Summary of the Invention

[0004] The present invention aims to solve the technical problem that the air outlet of the existing automotive air conditioning system occupies a large space.

[0005] On one hand, the present invention proposes an air outlet structure for an automotive air conditioner, including a housing, a lower trim panel, and an air guide assembly. The air guide assembly includes a first upper and lower air guide blade, a second upper and lower air guide blade, and a linkage mechanism. The housing has openings at both ends, with one end of the housing forming an air inlet. The lower trim panel includes a lower trim panel body extending obliquely upwards toward the vehicle. The lower wall of the housing, away from the air inlet, is connected to the first end of the lower trim panel body. The second end of the lower trim panel body is higher than the first end, making the horizontal plane where the second end of the lower trim panel body is located a standard plane. An air outlet channel is formed between the standard plane and the plane where the upper wall of the housing is located. The first upper and lower air guide blades are placed in the air outlet channel, and the second upper and lower air guide blades are located between the standard plane and the lower trim panel body. The first upper and lower air guide blades and the second upper and lower air guide blades are connected by the linkage mechanism.

[0006] The automotive air conditioning outlet structure described in this invention has at least the following advantages compared to existing technologies:

[0007] The automotive air conditioning vent structure can be installed on the car dashboard. The front opening of the housing forms an air inlet, and the lower trim panel is located at the rear end of the lower wall of the housing. The two ends of the lower trim panel are designated as the first end and the second end. Because it extends upwards towards the car, the first end is located below and in front of the second end, or the second end is located above and behind the first end. That is, the first end connects to the rear end of the lower wall of the housing, and the second end is higher than the lower wall of the housing. Additionally, the second end should generally be lower than the upper wall of the housing. This creates an air outlet channel between the horizontal plane of the second end of the lower trim panel and the plane of the upper wall of the housing. When the first upper and lower guide vanes are driven to move the second upper and lower guide vanes via a linkage mechanism, the airflow entering from the air inlet is adjusted and blown out through the air outlet channel, achieving the air outlet function of the air conditioning vent structure. Simultaneously, the second upper and lower guide vanes are located between the horizontal plane of the second end of the lower trim panel and the lower trim panel itself, meaning the second upper and lower guide vanes are below the air outlet channel. This reduces the size of the air outlet, facilitating the installation of surrounding components and enhancing the aesthetics of the car's interior.

[0008] Optionally, the linkage mechanism includes a fixed rod and a movable rod. The fixed rod is installed inside the housing. The two ends of the first upper and lower air guide vanes along the air outlet direction are respectively rotatably connected to the fixed rod and the movable rod. One end of the second upper and lower air guide vanes along the air outlet direction is rotatably connected to the fixed rod, and the other end of the second upper and lower air guide vanes along the air outlet direction is movably connected to the movable rod.

[0009] Optionally, the fixed rod is provided with a limiting groove, which is an arc-shaped limiting groove. The arc direction of the limiting groove matches the rotation direction of the second upper and lower air guide vanes. The second upper and lower air guide vanes are provided with limiting posts that match the limiting groove. The limiting posts are used to move along the limiting groove.

[0010] Optionally, the movable rod is provided with a first guide groove, and the second upper and lower air guide blades are provided with a first guide post that matches the first guide groove. The second upper and lower air guide blades are connected to the movable rod through the first guide post and the first guide groove. The first guide post is used to move along the first guide groove.

[0011] Optionally, the first upper and lower guide vanes are rotatably connected to the movable rod via a rotating shaft. The movable rod is provided with a second guide post, which is located on the side of the first guide groove away from the rotating shaft. The fixed rod is provided with a second guide groove that matches the second guide post. The movable rod is connected to the fixed rod via the second guide post and the second guide groove. The second guide post is used to move along the second guide groove.

[0012] Optionally, the side of the fixing rod away from the air inlet protrudes in a direction away from the air inlet to form a first fixing part and a second fixing part spaced apart. The first upper and lower air guide vanes are rotatably connected to the first fixing part, and the second upper and lower air guide vanes are rotatably connected to the second fixing part. The rotation axes of the second upper and lower air guide vanes and the second fixing part are located in the standard plane.

[0013] Optionally, the car air conditioning vent structure also includes a knob, one end of which extends into the vent channel to be driven and connected to the first upper and lower air guide vanes.

[0014] Optionally, the automotive air conditioning vent structure also includes an upper trim panel, which is located on the upper wall of the housing at the end away from the air inlet, and is installed in conjunction with the housing and the lower trim panel.

[0015] On the other hand, the present invention proposes a car including the aforementioned car air conditioning vent structure. The advantages of this car compared to the prior art are the same as those of the aforementioned car air conditioning vent structure, and will not be repeated here.

[0016] Optionally, two automotive air conditioning vent structures are symmetrically arranged, with the housings of the two automotive air conditioning vent structures connected to each other at the end away from the air inlet, the fixing rods of the air guide components of the two automotive air conditioning vent structures being connected as one unit, and the lower trim panels of the two automotive air conditioning vent structures being connected as one unit.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fitting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] In addition, it should be noted that in the description of the present invention, terms such as "upper," "lower," "front," and "rear" used to indicate orientation in various embodiments are only for simplifying the description of the positional relationships based on the accompanying drawings and do not mean that the elements and devices referred to must be operated in accordance with the specific orientation and limited operation, method, and structure in the specification. Such directional terms do not constitute a limitation on the present invention.

[0028] This paper establishes an XYZ coordinate system, where the X-axis represents the front-to-back direction of the vehicle, with the positive direction representing the front and the negative direction representing the rear; the Y-axis represents the left-to-right direction, with the positive direction representing the left and the negative direction representing the right; and the Z-axis represents the vertical direction, with the positive direction representing the top and the negative direction representing the bottom. It should be noted that the aforementioned X, Y, and Z-axis representations are for ease of description and simplification of the invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0029] like Figure 1-4As shown, this embodiment of the invention provides an air outlet structure for an automotive air conditioner, including a housing 1, a lower trim panel 2, and an air guide assembly 3. The air guide assembly 3 includes a first upper and lower air guide blade 31, a second upper and lower air guide blade 32, and a linkage mechanism. The housing 1 has openings at both ends, with one end of the housing 1 forming an air inlet 11. The lower trim panel 2 includes a lower trim panel body 21 extending obliquely upwards towards the vehicle. The lower wall of the housing 1, away from the air inlet 11, is connected to the first end of the lower trim panel body 21. The second end of the lower trim panel body 21 is higher than the first end, and the horizontal plane where the second end of the lower trim panel body 21 is located is a standard plane. An air outlet channel 12 is formed between the standard plane and the plane where the upper wall of the housing 1 is located. The first upper and lower air guide blade 31 is placed in the air outlet channel 12, and the second upper and lower air guide blade 32 is located between the standard plane and the lower trim panel body 21. The first upper and lower air guide blade 31 and the second upper and lower air guide blade 32 are connected by the linkage mechanism.

[0030] Specifically, the car air conditioning vent structure can be installed in any location, such as the car dashboard or center armrest. For ease of description, the following description uses the installation on the car dashboard as an example. The housing 1 has openings at both ends along the front-rear direction of the car. The front opening of the housing 1 forms an air inlet 11. The first upper and lower air guide blades 31 of the air guide assembly 3 can be connected to the knob 4. The knob 4 drives the first upper and lower air guide blades 31 to move up and down. During the movement, the first upper and lower air guide blades 31 drive the second upper and lower air guide blades 32 to move through the linkage mechanism, thereby realizing the air outlet angle and air volume in the air outlet channel 12. The lower trim panel 2 includes a lower trim panel body 21 and a bent section that mates with the side wall of the housing 1. The lower trim panel body 21 extends from the lower front to the upper rear. The lower trim panel body 21 can be a straight plate or a curved plate, with the two ends of the lower trim panel body 21 being the first end and the second end, respectively. Since it extends obliquely upwards towards the car, the first end is located below and in front of the second end, or in other words, the second end is located above and behind the first end. That is, the first end is connected to the rear end of the lower wall of the housing 1, and the second end is higher than the lower wall of the housing. In addition, the second end should generally be lower than the upper wall of the housing 1, thereby forming an air outlet channel between the horizontal plane where the second end of the lower trim panel body 21 is located and the plane where the upper wall of the housing 1 is located. The second upper and lower air guide vanes 32 can rotate in the standard plane and the space below it. The tilt angle of the lower trim panel body 21 can be determined according to the rotation angle of the second upper and lower air guide vanes 32. The second upper and lower air guide vanes 32 can rotate from a horizontal state to a state parallel to the lower trim panel body 21 to ensure that the air guide angle meets the requirements.

[0031] In this embodiment, when the first upper and lower guide vanes 31 are driven to move the second upper and lower guide vanes 32 via a linkage mechanism, the airflow entering through the air inlet 11 is adjusted and blown out through the air outlet 12, thus realizing the air outlet function of the air conditioning structure. Simultaneously, the second upper and lower guide vanes 32 are located between the horizontal plane of the second end of the lower trim panel body 21 and the lower trim panel body 21, meaning the second upper and lower guide vanes 32 are located below the air outlet 12. Only one upper and lower guide vane needs to be installed in the air outlet 12. Compared to existing solutions that require multiple upper and lower guide vanes in the air outlet duct, the size of the air outlet can be made smaller, reducing the space occupied by the air outlet, facilitating the installation of surrounding components, meeting the installation needs in confined spaces, and also improving the aesthetics of the car interior.

[0032] like Figure 5-6 As shown, optionally, the linkage mechanism includes a fixed rod 33 and a movable rod 34. The fixed rod 33 is installed inside the housing 1. The two ends of the first upper and lower guide vanes 31 along the air outlet direction are respectively rotatably connected to the fixed rod 33 and the movable rod 34. One end of the second upper and lower guide vanes 32 along the air outlet direction is rotatably connected to the fixed rod 33, and the other end of the second upper and lower guide vanes 32 along the air outlet direction is movably connected to the movable rod 34.

[0033] Specifically, the linkage mechanism is located near one side wall of the housing 1. For ease of description, the following description uses the linkage mechanism located near the right side wall of the housing 1 as an example. The fixed rod 33 is located near the right side wall of the housing 1. The upper and lower ends of the fixed rod 33 are connected to the upper wall and the lower wall of the housing 1, respectively. A movable rod 34 can be located on the left side of the fixed rod 33. The right rear end of the first upper and lower guide vanes 31 is rotatably connected to the fixed rod 33 around the first axis, which is along the Y-axis. The right front end of the first upper and lower guide vanes 31 is movably connected to the upper end of the movable rod 34. The left rear end of the first upper and lower guide vanes 31 is rotatably connected to the left side wall of the housing 1 around the second axis. The third axis is collinear with the first axis.

[0034] The right rear end of the second upper and lower guide vanes 32 is rotatably connected to the fixed rod 33 around the third axis. The right front end of the second upper and lower guide vanes 32 is movably connected to the middle of the movable rod 34. The movable connection can be a rotatable connection or a sliding connection, as described below. The second upper and lower guide vanes are connected to the movable rod 34 through the first guide post 322 and the first guide groove 341. The left rear end of the second upper and lower guide vanes 32 is rotatably connected to the left side wall of the housing 1 around the fourth axis. The fourth axis is collinear with the second axis.

[0035] In this embodiment, when the first upper and lower guide vanes 31 are driven to rotate up and down relative to the fixed rod 33 around the first axis, the first upper and lower guide vanes 31 transmit the driving force to the second upper and lower guide vanes 32 through the movable rod 34, so that the second upper and lower guide vanes 32 rotate up and down relative to the fixed rod 33 around the third axis, thereby realizing the simultaneous rotation of the first upper and lower guide vanes 31 and the second upper and lower guide vanes 32 to adjust the air volume and air angle of the air outlet channel 12.

[0036] like Figure 5-6 As shown, optionally, the fixed rod 33 is provided with a limiting groove 331, the limiting groove 331 is an arc-shaped limiting groove, the arc direction of the limiting groove 331 matches the rotation direction of the second upper and lower guide vanes 32, and the second upper and lower guide vanes 32 are provided with limiting posts 321 that match the limiting groove 331, the limiting posts 321 are used to move along the limiting groove 331.

[0037] In this embodiment, the limiting groove 331 can be approximately an arc-shaped limiting groove curving towards the rear of the vehicle. The center of the limiting groove 331 is located on the third axis. The arc direction of the limiting groove 331 is consistent with the rotation direction of the second upper and lower guide vanes 32. When the second upper and lower guide vanes 32 rotate up and down, the rotation angle of the second upper and lower guide vanes 32 can be limited by the movement of the limiting post 321 on them and the limiting groove 331 on the fixing rod 33. The limiting post 321 can be integrally formed with the second upper and lower guide vanes 32 or detachably connected.

[0038] When the limiting post 321 moves to abut against the upper end of the limiting groove 331, the second upper and lower guide vanes 32 are in a horizontal state. When the limiting post 321 moves to abut against the lower end of the limiting groove 331, the second upper and lower guide vanes 32 tilt from the lower front to the upper rear, achieving upward airflow. The center angle corresponding to the limiting groove 331 can be adjusted according to actual needs to achieve adjustment of the upper and lower air outlet angles.

[0039] like Figure 5-6 As shown, optionally, the movable rod 34 is provided with a first guide groove 341, and the second upper and lower guide vanes 32 are provided with a first guide post 322 that matches the first guide groove 341. The second upper and lower guide vanes 32 are connected to the movable rod 34 through the first guide post 322 and the first guide groove 341. The first guide post 322 is used to move along the first guide groove 341.

[0040] Specifically, the middle part of the movable rod 34 is provided with a first guide groove 341. The first guide groove 341 can be a long strip groove. The first guide groove 341 extends along the straight line where the two ends of the movable rod 34 are located. The front right side of the second upper and lower air guide blades 32 can be provided with a first guide post 322. The first guide post 322 can be integrally formed with the second upper and lower air guide blades 32 or can be detachably connected.

[0041] In this embodiment, initially, the first upper and lower guide vanes 31 can drive the second upper and lower guide vanes 32 to move synchronously upward or downward via the movable rod 34. When the limiting post 321 of the second upper and lower guide vanes 32 abuts against the upper or lower end of the limiting groove 331, the first upper and lower guide vanes 31 can continue to rotate. By utilizing the relative movement of the movable rod 34 and the first guide post 322, the second upper and lower guide vanes 32 remain stationary, while the first upper and lower guide vanes 31 continue to move, increasing the adjustment of the air outlet angle.

[0042] like Figure 5-6 As shown, optionally, the first upper and lower guide vanes 31 are rotatably connected to the movable rod 34 via a rotating shaft. The movable rod 34 is provided with a second guide post 342, which is located on the side of the first guide groove 341 away from the rotating shaft. The fixed rod 33 is provided with a second guide groove 332 that matches the second guide post 342. The movable rod 34 is connected to the fixed rod 33 via the second guide post 342 and the second guide groove 332. The second guide post 342 is used to move along the second guide groove 332.

[0043] Specifically, the right front end of the first upper and lower guide vanes 31 can be rotatably connected to the movable rod 34 via a pivot. A second guide post 342 can be provided at the lower end of the movable rod 34. The second guide post 342 can be made of polyoxymethylene thermoplastic crystalline polymer (POM) to improve wear resistance and prevent abnormal noise. The second guide post 342 can be integrally formed with the movable rod 34 or detachably connected. A second guide groove 332 can be provided at the lower end of the fixed rod 33. The second guide groove 332 can be a curved groove, and its position can be determined according to the movement trajectory of the first upper and lower guide vanes 31. The rotation angle of the second upper and lower guide vanes 32 can be limited by the movement of the second guide post 342 and the second guide groove 332.

[0044] Here, the lower wall of the housing 1 is recessed towards the side away from the upper wall of the housing 1 to form a mounting groove, and the lower end of the fixing rod 33 is inserted into the mounting groove.

[0045] In this embodiment, when the second guide post 342 of the movable rod 34 abuts against the lower end of the second guide groove 332, and the limiting post 321 of the second upper and lower guide vanes 32 abuts against the lower end of the limiting groove 331, both the first upper and lower guide vanes 31 and the second upper and lower guide vanes 32 are tilted from the front-lower to the rear-upper direction, at which time the air can be guided to the upper limit position; when the second guide post 342 of the movable rod 34 abuts against the upper end of the second guide groove 332, and the limiting post 321 of the second upper and lower guide vanes 32 abuts against the upper end of the limiting groove 331, the first upper and lower guide vanes 31 are tilted from the front-upper to the rear-lower direction, and the second upper and lower guide vanes 32 are in a horizontal state, at which time the air can be guided to the lower limit position.

[0046] It should be noted that the second upper and lower air guide vanes 32 cannot be rotated to a tilted state from front to upper to rear to lower, mainly to avoid the lower trim panel body 21 obstructing the airflow and preventing the air from being guided to the lower limit position.

[0047] like Figure 4-6 As shown, optionally, the side of the fixing rod 33 away from the air inlet 11 protrudes in a direction away from the air inlet 11 to form a first fixing part 333 and a second fixing part 334 spaced apart. The first upper and lower air guide vanes 31 are rotatably connected to the first fixing part 333, and the second upper and lower air guide vanes 32 are rotatably connected to the second fixing part 334. The rotation axes of the second upper and lower air guide vanes 32 and the second fixing part 334 are located in the standard plane.

[0048] In this embodiment, a first fixing part 333 and a second fixing part 334 are vertically spaced at the rear end of the fixing rod 33. The upper surface of the first fixing part 333 is smooth and roughly matches the curvature of the upper surface of the first upper and lower guide vanes 31, reducing wind resistance and improving aesthetics. The arrangement of the second fixing part 334 is similar to that of the first fixing part. Furthermore, the rotation axis of the second fixing part 334 and the second upper and lower guide vanes 32 are located in a standard plane. When the second upper and lower guide vanes 32 rotate to a horizontal state, they are flush with the second end of the lower trim panel body 21, which is beneficial for the air guidance of the second upper and lower guide vanes 32.

[0049] like Figure 1 , 4 As shown, optionally, the car air conditioning vent structure also includes a knob 4, one end of which extends into the air vent 12 to be driven and connected to the first upper and lower air guide vanes 31.

[0050] In this embodiment, one end of the dial 4 is for hand use, and the other end can be fitted onto the first upper and lower air guide vanes 31. The driver or passenger can adjust the airflow by operating the dial 4.

[0051] In some other embodiments, the air guide assembly 3 may also include left and right air guide blades and connectors. The knob 4 is movably sleeved on the first upper and lower air guide blades 31. One end of the knob 4 extending into the air outlet channel 12 can be connected to the left and right air guide blades through the connectors. Moving the knob 4 left and right drives the left and right air guide blades to move, thereby adjusting the left and right air outlet angle and air volume.

[0052] like Figure 1-2 As shown, optionally, the car air conditioning vent structure also includes an upper trim panel 5, which is located on the upper wall of the housing 1 at the end away from the air inlet 11, and the upper trim panel 5 is installed in conjunction with the housing 1 and the lower trim panel 2.

[0053] In this embodiment, the upper trim panel 5 can be snapped to the rear end of the upper wall of the housing 1, and the lower trim panel body 21 can be snapped to the rear end of the lower wall of the housing 1. The upper trim panel 5 and the lower trim panel 2 serve to decorate the car. At the same time, an air vent is formed between the upper trim panel 5 and the lower trim panel body 21.

[0054] like Figure 1 As shown, another embodiment of the present invention proposes a car including the aforementioned car air conditioning vent structure. The advantages of this car compared to the prior art are the same as those of the aforementioned car air conditioning vent structure, and will not be repeated here.

[0055] like Figure 1 As shown, optionally, two automotive air conditioning vent structures are symmetrically arranged, and the housings 1 of the two automotive air conditioning vent structures are connected to each other at the end away from the air inlet 11. The fixing rods 33 of the air guide components 3 of the two automotive air conditioning vent structures are connected into one piece, and the lower trim panels 2 of the two automotive air conditioning vent structures are connected into one piece.

[0056] In this embodiment, two symmetrically arranged automotive air conditioning vent structures are integrated together to increase the air volume and meet the blowing needs of high-volume applications. Simultaneously, connecting the rear ends of the housings 1 of the two automotive air conditioning vent structures facilitates installation; connecting the fixing rods 33 of the air guide components 3 of the two automotive air conditioning vent structures into one unit facilitates molding; and connecting the lower trim panels 2 of the two automotive air conditioning vent structures into one unit improves the overall aesthetics.

[0057] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, and all such changes and modifications will fall within the scope of protection of the present invention.
