Description

Technical Field

[0001] This invention belongs to the field of air outlet technology, and particularly relates to an air outlet assembly and a vehicle. Background Technology

[0002] In automotive air conditioning, home appliances, or HVAC (Heating, Ventilation, and Air Conditioning) systems, the air outlet assembly is a key component for regulating airflow direction and volume distribution, and its structural design directly affects user comfort and experience. To achieve more flexible airflow control, existing technologies often employ a double-layer or multi-layer air outlet structure. This involves setting up a first and second air outlet zone with staggered front and rear positions within the housing, each equipped with independent air outlet blade assemblies. This stepped or staggered layout helps create a composite airflow, improving the coverage and gentleness of the air delivery.

[0003] However, in practical applications, achieving synchronized oscillation of the two sets of exhaust blades has become a major technical challenge. Because there is a significant difference in height between the first and second exhaust blades in the airflow direction, using traditional rigid linkages or gears for direct transmission can easily lead to transmission interference, motion jamming, or even mechanical damage due to mismatched spatial angles. To address this issue, some existing solutions use two independent drive motors to control the front and rear blades separately. While this allows for independent oscillation, it not only increases costs and space requirements but also makes it difficult to ensure strict synchronization of the two sets of blades, affecting airflow coordination. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an air outlet assembly that utilizes a single drive component to drive two sets of staggered air outlet zones.

[0005] The objective of this invention can be achieved through the following technical solution: an air outlet assembly, comprising:

[0006] The housing has an air outlet cavity inside, which is divided into a first air outlet area and a second air outlet area. The first air outlet area is provided with a number of first air outlet blades, and the second air outlet area is provided with a number of second air outlet blades. The swing directions of the first air outlet blades and the second air outlet blades are parallel, and the plane where the rotation axis of each first air outlet blade is located is not on the same plane as the plane where the rotation axis of each second air outlet blade is located.

[0007] A drive unit, which is disposed on the outside of the housing, includes a drive shaft, and the drive shaft is connected to the first air outlet blade in a transmission manner;

[0008] A transmission mechanism is disposed between the first air outlet blade and the second air outlet blade to achieve synchronous and unidirectional oscillation of the two. The transmission mechanism includes a universal joint assembly and a connecting member. The universal joint assembly includes a driving member and a driven member connected to each other. The driving member is connected to the rotation shaft of the first air outlet blade and rotates synchronously. The driven member has rotational freedom in at least two non-parallel rotational directions relative to the driving member. The connecting member is connected to the rotation shaft of the second air outlet blade and rotates synchronously. The connecting member has a connecting cavity. The end of the driven member extends into the connecting cavity and forms a limiting fit with the connecting cavity in the circumferential direction. When the driving member drives the driven member to rotate, it forces the connecting member to rotate synchronously, thereby driving the second air outlet blade to oscillate. At the same time, the end of the driven member can slide along the depth direction of the connecting cavity.

[0009] In the above-mentioned air outlet assembly, the end of the driven member is fixedly provided with a sliding part that extends into the connecting cavity. A limiting part is fixedly provided on the sliding part. A limiting groove is formed on the inner wall of the connecting cavity along its depth direction. The limiting part extends into the limiting groove to realize synchronous rotation between the driven member and the connecting member. At the same time, the limiting part can slide in the limiting groove.

[0010] In the above-mentioned air outlet assembly, there are two limiting parts, and the two limiting parts are symmetrically arranged on the sliding part along the sliding axis of the sliding part.

[0011] In one of the above-mentioned air outlet assemblies, the sliding part is a spherical part.

[0012] In the aforementioned air outlet assembly, the driven member includes a transmission part, which is connected to the driving member via a multi-directional rotation structure to achieve at least two non-parallel rotational degrees of freedom. The end of the transmission part extends into the connecting cavity.

[0013] In one of the above-mentioned air outlet assemblies, the driving component includes a drive shaft fork, the multi-directional rotation structure includes a connecting shaft, the drive shaft fork is fixedly mounted on the rotating shaft of the first air outlet blade, the connecting shaft is rotatably mounted on the drive shaft fork, the transmission part is hinged to the connecting shaft, and the axis of the connecting shaft is perpendicular to the rotation axis of the transmission part.

[0014] In one of the above-mentioned air outlet assemblies, the end of the transmission part is integrally formed with a fork-shaped connector, and the two fork arms of the fork-shaped connector are respectively hinged to the opposite sides of the connecting shaft.

[0015] A vehicle comprising the aforementioned air vent assembly.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a universal joint assembly with multiple degrees of freedom and a connecting cavity with limiting fit, even if the rotation axes of the first air outlet blade and the second air outlet blade are not on the same plane, they can still be guaranteed to swing synchronously and in the same direction; only one external drive unit is needed to control the blades of the two air outlet areas at the same time, without the need to set a separate drive device for the second air outlet area, saving space, reducing the number of parts and manufacturing costs.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0026] like Figures 1-6As shown, an air outlet assembly for an automotive air conditioning system is provided. The air outlet assembly includes a housing 100, a drive unit 200, and a transmission mechanism.

[0027] The housing 100 forms an air outlet cavity, which is divided into a first air outlet area 101 and a second air outlet area 102 arranged adjacent to each other. Several parallel first air outlet blades 103 are installed in the first air outlet area 101, and several corresponding second air outlet blades 104 are arranged in the second air outlet area 102. The oscillation direction of each first air outlet blade 103 and second air outlet blade 104 is the same, but their respective axes of rotation are not coplanar—that is, the axes of rotation of all first air outlet blades 103 are located on a first plane, while the axes of rotation of all second air outlet blades 104 are located on a second plane that is parallel to but offset from it.

[0028] The drive unit 200 is fixed to the outside of the housing 100, and its output end is provided with a drive shaft. The drive shaft is connected to the rotating shaft of one of the first air outlet blades 103, thereby driving all the first air outlet blades 103 to swing synchronously.

[0029] A transmission mechanism is provided between the first air outlet zone 101 and the second air outlet zone 102 to achieve synchronous and unidirectional oscillation of the first air outlet blade 103 and the second air outlet blade 104. This transmission mechanism includes a universal joint assembly 300 and a connecting member 105. The universal joint assembly 300 consists of a driving member 301 and a driven member 302. The driven member 302 can rotate freely relative to the driving member 301 in at least two non-parallel directions to accommodate the spatial arrangement where the shafts of the two sets of blades are not in the same plane. The connecting member 105 is connected to the shaft of the second air outlet blade 104 and rotates synchronously.

[0030] The driving member 301 is fixedly connected to the end shaft of the first air outlet blade 103 and rotates synchronously with it; the end of the driven member 302 extends into the connecting cavity 106 inside the connector 105. The two form a limiting fit in the circumferential direction to ensure effective torque transmission. At the same time, the driven member 302 can slide freely in the axial direction (i.e., the depth direction) of the connecting cavity 106.

[0031] When the drive unit 200 is started, the drive shaft drives the first air outlet blade 103 to swing, and the driving member 301 rotates accordingly. The motion is transmitted to the driven member 302 through the universal joint assembly 300, and then rotates synchronously through the limit and drive connector 105. Finally, the second air outlet blade 104 swings at the same angle and direction, so as to achieve consistent adjustment of the air outlet direction of the two areas.

[0032] By setting up a universal joint assembly 300 with multiple degrees of freedom and a connecting cavity 106 with a limiting fit, even if the rotation axes of the first air outlet blade 103 and the second air outlet blade 104 are not on the same plane, they can still be guaranteed to swing synchronously and in the same direction. Only one external drive unit 200 is needed to control the blades of the two air outlet areas at the same time, without the need to set up a separate drive device for the second air outlet area 102, saving space, reducing the number of parts and manufacturing costs.

[0033] Specifically, a sliding portion 303 is fixedly provided at the end of the driven member 302, which extends axially into the connecting cavity 106 inside the connector 105. A limiting portion 304 (e.g., a radially protruding bump) is integrally formed or fixedly connected to the outer peripheral surface of the sliding portion 303. Correspondingly, a limiting groove 107 is formed on the inner wall of the connecting cavity 106 along its depth direction (i.e., axial direction). The cross-sectional shape of the limiting groove 107 matches the limiting portion 304, and the limiting portion 304 is embedded in the limiting groove 107, so that the driven member 302 and the connector 105 form a rigid limiting fit in the circumferential direction. When the driven member 302 rotates with the driving member 301, the limiting portion 304 pushes the side wall of the limiting groove 107, thereby causing the connector 105 to rotate synchronously, and thus driving the second exhaust blade 104 to swing. Meanwhile, since the limiting groove 107 extends along the depth direction of the connecting cavity 106, the limiting part 304 can slide freely in the groove, allowing the sliding part 303 to undergo relative displacement in the axial direction, thus avoiding transmission jamming or stress concentration.

[0034] Two limiting parts 304 are fixedly provided on the sliding part 303 at the end of the driven member 302. These two limiting parts 304 are centrally symmetrically arranged along the sliding axis of the sliding part 303 (i.e., the depth direction of the connecting cavity 106) and located on the outer circumferential surface of the sliding part 303. Correspondingly, two axially extending limiting grooves 107 are formed on the inner wall of the connecting cavity 106, their positions corresponding one-to-one with the two limiting parts 304. When the driven member 302 rotates, the two limiting parts 304 synchronously push the sidewalls of their respective limiting grooves 107, achieving double-point circumferential limiting and effectively preventing the sliding part 303 from deflecting or shaking within the connecting cavity 106.

[0035] The sliding part 303 is integrally constructed as a spherical part, meaning its outer contour is a spherical surface. This spherical part can be embedded in the connecting cavity 106, forming line contact with the inner wall of the connecting cavity 106 in the assembled state. This significantly reduces frictional resistance during relative movement and effectively avoids localized stress concentration caused by manufacturing tolerances, assembly deviations, or temperature changes, thereby preventing jamming during transmission. The limiting part 304 protrudes radially outward along the spherical surface, ensuring effective contact with the limiting groove 107 during spherical sliding.

[0036] Based on the aforementioned air outlet assembly, such as Figure 3As shown, the driven member 302 includes a transmission part 305 constituting the extension of the main body. The proximal end of the transmission part 305 (i.e., the end near the driving member 301) is connected to the driving member 301 via a multi-directional rotation structure. Ensuring that the transmission part 305 has at least two non-parallel rotational degrees of freedom relative to the driving member 301, the distal end (i.e., the end point) of the transmission part 305 extends axially and into the connecting cavity 106 inside the connecting member 105. A sliding part 303 is fixedly provided on this end point, and the sliding part 303 has symmetrically arranged limiting parts 304, which cooperate with the limiting groove 107 on the inner wall of the connecting cavity 106 to achieve synchronous circumferential rotation and axial sliding.

[0037] like Figure 3 As shown, the driving member 301 includes a drive shaft fork 306, which is fixedly mounted on the end of the rotating shaft of the first air outlet blade 103 and rotates synchronously with it. The drive shaft fork 306 has a U-shaped or fork-shaped structure, with an opening space formed between its two side arms. A connecting shaft 307 is provided in this opening space, and its two ends are rotatably supported on the two side arms of the drive shaft fork 306. The drive part 305 of the driven member 302 has a fork-shaped connector 308 integrally formed at its end near the driving member 301. The fork-shaped connector 308 is also U-shaped, with its two fork arms extending outward from the end of the drive part 305 and respectively sleeved on the opposite sides of the connecting shaft 307, forming a rotating pair with the connecting shaft 307 by means of a pin or direct hinge. Thus, the axis of the connecting shaft 307 is perpendicular to the rotation axis of the drive part 305 itself, forming a typical cross-shaped universal joint structure. This structure allows the transmission unit 305 to swing freely in two mutually perpendicular planes relative to the transmission shaft fork 306.

[0038] When the first air outlet blade 103 swings, it drives the drive shaft fork 306 to rotate, and transmits the motion to the fork joint 308 through the connecting shaft 307, thereby driving the transmission part 305 to rotate synchronously. Even if there is a front-to-back misalignment or a slight angular deviation between the blade shafts of the first air outlet area 101 and the second air outlet area 102, the cross shaft structure can still smoothly transmit the rotational motion, ensuring that the second air outlet blade 104 and the first air outlet blade 103 swing synchronously and in the same direction.
