Description

Technical Field

[0001] Embodiments of the present disclosure also relate to HVAC systems for vehicle cabins, methods and computer software for controlling vent assemblies, and vehicles having such systems or incorporating such vent assemblies. Background Art

[0002] Modern vehicles are typically provided with an HVAC (heating, ventilation and air conditioning) system for their vehicle cabin. The HVAC system is capable of controlling the temperature within the vehicle cabin (i.e., heating the vehicle cabin or cooling the vehicle cabin), and is capable of directing streams or jets of heated or cooled air into or onto desired areas and / or desired surfaces within the vehicle cabin, such as a windshield (to provide a defog function), or onto the face, body or feet of an individual sitting in the vehicle cabin, or just generally into the cabin volume to promote air movement and change / maintain the cabin temperature. For example, air may be directed into the front footwells, into the central area of ​​the cabin, or onto the upper body or face of the driver. Air is typically directed into the cabin through vents provided in the cabin structure.

[0003] Face level vents may often be provided on the instrument panel to deliver the most noticeable air flow to the user (driver or front passenger). Typically, these vents are configured with functionality that enables the user to adjust the direction of the air flow (e.g., onto or away from the user's face) and adjust the output of the vents according to the user's preference. Conventional air vents have vertical blades for controlling the left and right direction of the air flow and horizontal blades for controlling the up and down direction. The vertical blades are typically manually operated by the user and allow the entire air flow from the vent to be directed from the center of the vent to the left or right side.

[0004] While conventional face vents are located on either side of the driver and on either side of the passenger, the present disclosure contemplates placing the face vents directly in front of the driver (behind the steering wheel) and placing the face vents directly in front of the front passenger. Placing the air vents directly in front of the user requires more options for lateral air flow control to target specific areas and avoid specific areas. Summary of the invention

[0005] Various aspects and embodiments of the present invention provide vent assemblies, HVAC systems, methods and computer software for vehicle cabins, and vehicles having cabins provided with such HVAC systems and one or more such vent assemblies. The vehicle cabin is preferably the cabin of an automobile, but may alternatively be for a truck or other commercial vehicle, a marine vessel, or an aircraft.

[0006] According to one aspect of the present invention, there is provided a vent assembly for a vehicle compartment, the vent assembly comprising:

[0007] a first set of blades and a second set of blades, the first set of blades and the second set of blades each being configured to direct air into a vehicle cabin;

[0008] a first cam path and a second cam path, the first cam path and the second cam path being defined by one or more cams mounted to a rotatable common shaft;

[0009] a first cam follower operatively coupled between the first cam path and the first set of blades and a second cam follower operatively coupled between the second cam path and the second set of blades;

[0010] Wherein, rotation of the common shaft rotates the one or more cams and causes the first and second cam followers to follow respective first and second cam paths, thereby adjusting the relative angles of the first and second sets of blades.

[0011] The first cam path and the second cam path may be defined on respective cam wheel discs, both cam wheel discs being mounted to the shaft. In an alternative implementation, the first cam path and the second cam path may be defined on the same cam wheel disc. For example, the cam wheel disc may have a first face and a second face located on opposite sides of the cam wheel disc, wherein the first cam path may be defined on the first face of the cam wheel disc and the second cam path may be defined on the second face of the same cam wheel disc. In this case, it will be understood that the cam follower will engage with opposite faces of the same cam wheel disc. Alternatively, the first cam path and the second cam path may be defined on the same side of a single cam wheel disc, such as being defined as an inner path and an outer path on the same side of a single cam wheel disc.

[0012] In either of these cases, the cam path may be a track defined on one or more planar surfaces of the cam wheel. The planar surfaces may be perpendicular to the axis of rotation of the common shaft. In this case, the first cam follower and the second cam follower may each include a pin for engaging in the first track and the second track, respectively.

[0013] In the case of two cam wheels, the first cam path and the second cam path can be arranged to face each other. That is, the first cam path can be defined on the side of the first cam wheel facing the second cam wheel, and the second cam path can be defined on the side of the second cam wheel facing the first cam wheel. In this case, at least a portion of the first cam follower and the second cam follower can be slidably contacted with each other between the cam carrying the first cam path and the cam wheel carrying the second cam path. Preferably, the first cam follower and the second cam follower are held against each other between the cam wheels to hold the corresponding pins in the track. In this way, the cam wheel and the cam follower have a compact and self-supporting structure, and the pins are always firmly held in the track without the need for additional fixing elements.

[0014] The cam followers may extend beyond the cam wheel disc and be restricted in movement except in one direction of action parallel to the planar surface of the cam wheel disc, whereby rotation of the common shaft causes the cam followers to move in the direction of action as the cam path changes its position relative to the axis of rotation of the common shaft as it approaches and moves away from the axis of rotation of the common shaft. The direction of action may be radial relative to the axis of the common shaft. Thus, the position of each cam follower in the direction of action depends on the rotational position of the common shaft and the shape of the corresponding cam path.

[0015] The cam follower may be coupled to the set of blades so that each blade in the set is pivoted about its own blade axis when the cam follower moves in the direction of action. The blade axes of each blade in the blade set may be parallel to each other. The relative position of the cam follower in the direction of action determines the corresponding blade configuration.

[0016] Rotation of the common shaft and thus the following of the cam followers in their first and second cam paths allows the respective angles of the first and second sets of blades to be adjusted in different ways. Since parts (but not all) of the two cam paths may coincide, for parts of the common shaft rotation the first and second sets of blades move together (wherein the relative angles of the first and second sets of blades do not change), but for other parts of the common shaft rotation the first and second sets of blades move in different ways (wherein the relative angles of the first and second sets of blades change).

[0017] In this way, rotation of a single shaft may be used to control two different sets of blades in different ways (but not independently).

[0018] Each of the cam paths may define a continuous loop.In this way, a desired blade configuration between two blade sets may be achieved by rotation of the common shaft, and the degree of common shaft rotation required may be minimized by selecting the direction of rotation of the common shaft.

[0019] Although the present technique may be implemented manually by rotating the common shaft directly or indirectly, through manual operation by a user (eg, by turning a dial), preferably a motor is provided to rotate the shaft.

[0020] A (electronic) controller may be provided for controlling the position of the first set of blades and the second set of blades by adjusting the rotational position of the common shaft. The controller may be configured to select the rotational direction of the shaft according to which direction will achieve the desired configuration of the first set of blades and the second set of blades by the smallest shaft rotation.

[0021] While the present technology can be used with either horizontal or angled blades, the blades in both sets can be generally vertical. Particularly with respect to facial vents, this helps achieve a desired air flow configuration to aim at or avoid the driver and / or passengers.

[0022] A vent assembly controlled by a first set of blades and a second set of blades may have the first set of blades and the second set of blades arranged adjacent to each other, whereby a single wide air flow path exits the vent assembly when the blades of the first set of blades and the second set of blades are aligned in the same direction, and two flow paths of different directions exit the vent assembly in divergent directions where they remain separate or in converging directions where they mix to form a single concentrated air flow when the blades of the first set of blades and the second set of blades are oriented differently from each other. The axes of rotation of the blades in each set may be parallel.

[0023] In a ventilation assembly according to the present invention, the first set of blades and the second set of blades are arranged side by side, for example, in a generally horizontal direction across the vehicle dashboard in front of the driver or passenger, and the first set of blades are arranged to the right of the second set of blades, and the first cam path and the second cam path can be defined so that the first set of blades and the second set of blades can be configured into each of the following configurations:

[0024] a first neutral configuration, in which both sets of blades are aligned in the same forward direction,

[0025] The second configuration, in which the two sets of blades are aligned in the same leftward direction,

[0026] The third configuration, in which the two sets of blades are aligned in the same rightward direction,

[0027] a fourth configuration wherein the first set of blades are aligned in a leftward direction and the second set of blades are aligned in a rightward direction to converge and focus the air flow exiting the vent assembly, and

[0028] A fifth configuration, wherein the first set of blades are aligned in a rightward direction and the second set of blades are aligned in a leftward direction to separate the air flow into separate flows.

[0029] In some implementations, the first neutral configuration is arranged to occur twice in a complete rotation of the common shaft. Starting from a first one of the first neutral configurations, rotation of the common shaft in a first direction may move the blades into a second configuration, and rotation of the common shaft in a second direction may move the blades into a third configuration. Starting from a second one of the first neutral configurations, rotation of the common shaft in one direction may move the blades into a fourth configuration, and rotation of the common shaft in an opposite direction may move the blades into a fifth configuration.

[0030] The presence of two neutral positions, each surrounded by a pair of other (related) configurations, provides a natural feeling transition for the user - that is, it is not always necessary to transition through multiple undesirable modes before reaching the desired mode.

[0031] The above arrangement is provided by the shape of the cam path around the axis of the common shaft. The first path may have a rotational symmetry of order 2 around its axis of rotation (and have two mirror symmetry axes), while the second path may have no rotational symmetry (and have one mirror symmetry axis). The first cam path may include two lobes of approximately equal size on opposite sides of the axis of rotation of the common shaft and defining four first path positions, the four first path positions including: two first path minimum positions close to the axis of rotation and offset 180 degrees relative to each other; and two first path maximum positions away from the axis and offset 180 degrees relative to each other and offset about 90 degrees relative to the minimum position. The second path may include: a larger lobed angle, the larger lobed angle is located on one side of the shaft and extends over a maximum range away from the shaft at a rotation position corresponding to about 90 degrees of rotation of the common shaft between the first maximum position and the first minimum position of the first cam path; and a smaller lobed angle is located on the other side of the shaft and extends over a minimum range close to the shaft at a rotation position corresponding to about 90 degrees of rotation of the common shaft between the second maximum position and the second minimum position of the first cam path.

[0032] Therefore, rotation of the common axis within a 360 degree rotation provides four extreme positions, among which:

[0033] 1 The first maximum position of the first cam path coincides with the minimum range of the second cam path;

[0034] 2 The first minimum position of the first cam path is kept coincident with the minimum range of the second cam path;

[0035] 3 the second maximum position of the first cam path coincides with the maximum range of the second cam path; and

[0036] 4 The second minimum position of the first cam path is kept coincident with the maximum range of the second cam path.

[0037] There are also intermediate positions between the four extreme positions, and these positions provide two cases of a first neutral configuration (position 5, position 6 in Table 1 below) and the following two cases (position 7, position 8 in Table 1), in which the first set of blades is in a neutral position and the second set of blades is in a maximum position (e.g., oriented to the left) or a minimum position (i.e., oriented to the right).

[0038]

[0039]

[0040] Table 1

[0041] Table 1 identifies possible arrangements of cam paths and resulting vent configurations. With reference to cam path 1, 2 entries, maximum refers to the maximum distance from the common shaft axis, minimum refers to the minimum distance from the common shaft axis, and intermediate refers to the intermediate position. It can be seen that the mirror symmetry axes of the first cam path and the second cam path are offset by approximately 45 degrees relative to each other.

[0042] It is evident from Table 1 that the cam path arranges the blade assembly to travel through the above configurations as the common shaft rotates through 360 degrees. It is also evident that for changes from one configuration to another, the direction of rotation of the common shaft affects the number of configurations that the vent assembly passes through before reaching the new configuration. The first neutral configuration exists in two different common shaft rotational positions, but which configuration is adjacent to the first neutral configuration depends on which of the two positions (position 5 or position 6 in Table 1, 180 degrees apart) the shaft is oriented in. A controller can be provided to determine the rotational direction required to reach the desired configuration of the vent assembly from the current configuration via the least number of undesirable configurations.

[0043] Therefore, according to an aspect of the present invention, there is provided a method of controlling a vent assembly as defined above, the method comprising:

[0044] determining a current blade configuration of the first set of blades and the second set of blades,

[0045] Select the desired blade configuration,

[0046] determining a minimum rotation angle of the shaft required to configure the first set of blades and the second set of blades into a desired configuration; and

[0047] The control axis rotates by this smaller angle.

[0048] Computer software may be provided which, when executed, is arranged to perform the method defined above.

[0049] It is noted that two undefined configurations (position 7, position 8 in Table 1) result in vent assembly flows that are unlikely to be used in practice. In these positions of the common axis, one set of blades faces forward and the other set of blades is separated from or converges with the set of blades.

[0050] According to one aspect of the invention, there is provided a vehicle comprising a vent assembly as described above, the vehicle comprising a vent outlet in the vehicle cabin, and wherein the vent outlet is disposed directly in front of the front seats of the vehicle. The vent outlet may be disposed directly behind the steering wheel of the vehicle. The first set of blades and the second set of blades may be configured to be in a concentrated mode in which the first set of blades and the second set of blades are angled with respect to each other and air converges into a flow to pass through the steering wheel and toward the driver.

[0051] According to another aspect, there is provided a vent assembly for a vehicle cabin, the vent assembly comprising:

[0052] a first set of blades and a second set of blades, the first set of blades and the second set of blades each for directing air through the vent outlet into a vehicle cabin;

[0054] Wherein, the controller is operable to adjust respective angles of the first set of blades and the second set of blades to rotate toward each other to form a converging air flow.

[0055] According to one aspect of the invention, a vehicle is provided, comprising a vent assembly as described in the preceding paragraphs, wherein the vent outlet is disposed behind a steering wheel of the vehicle, and wherein the convergent air flow is discharged from the vent outlet and through the steering wheel toward a driver of the vehicle.

[0056] Advantageously, such a configuration can be aimed through the steering wheel and between the driver's hands and arms to reach the driver's face.

DETAILED DESCRIPTION

[0120] Figure 1 A vehicle 1 is shown in which the present invention may be used. The vehicle 1 includes a cabin 2 defining an interior space of the vehicle allocated for the driver, passengers and storage. It is desirable that the environment within the cabin 2 be controlled to be comfortable for the driver and passengers, as well as to ensure a clear view out of the windshield and windows (which may be susceptible to fogging depending on temperature and humidity conditions inside and outside the vehicle).

[0121] The vehicle compartment 2 can be served by a variety of vents, each of which can deliver air to different areas (horizontally and / or vertically) of the vehicle compartment 2. Specific areas of the vehicle compartment 2 can be served by controlling the rate at which air flows through the vents serving that area and / or by adjusting the direction of one or more vents. For example, a first group of vents may include one or more facial vents for directing air onto the face and upper body of the driver or front passenger. A second group of vents may include windshield vents for directing air onto the windshield and / or other cabin windows to provide a defog function. A third group of vents can release air into the vehicle footwell space. The present disclosure relates primarily to the first group of vents, and in particular to vents capable of providing adjustable air flow directionality, but the present invention is not limited to facial vents in its application.

[0122] The vehicle cabin 2 is provided with an instrument panel 3 (including an instrument panel and its instruments), and a driver-side vent 5 and a passenger-side vent 4 are provided in the instrument panel 3. These vents are capable of directing air toward the driver and the passenger, respectively. According to the arrangement of the present disclosure, the driver-side vent 5 is provided behind the steering wheel 6 of the vehicle 1. Each of the vents 4, 5 includes an outlet (orifice) not shown in the instrument panel 3, and the instrument panel 3 has a cavity behind the outlet, which is also not shown, and horizontal blades and vertical blades (to be discussed further below) are provided in the cavity, which can be adjusted to direct the air flow out of the orifice. A vent assembly ( Figure 1 ) and the ventilation assembly includes horizontal blades and vertical blades and means for controlling the position (angle) of the horizontal blades and the vertical blades. Ducts (not shown for clarity) are also provided that provide fluid (air flow) communication between the blower 7 (which drives air into the ducts) and the vents 4, 5. The present disclosure is primarily, but not necessarily exclusively, directed to the regulation of the vertical blades (which control the horizontal direction of the air flow) - alternative implementations may apply the techniques described herein to horizontal (or diagonal) blades to affect regulation in other directions of the air flow.

[0123] Reference Figure 2, a simplified vent assembly and control function for a vehicle cabin vent is shown to include a user interface 102, an electronic controller 104, a motor 106, a first cam 108, a second cam 110, a first cam follower 112, a second cam follower 114, a first set of blades 116, and a second set of blades 118. In operation, a user uses the user interface 102 to select an air flow configuration for the vent. This may involve the selection of a desired air flow pattern, an example of which will be described later. In response to the user selection, the controller 104 determines the amount of rotation of the output shaft of the motor 106 required to achieve the desired air flow configuration, and causes the motor 106 to be driven accordingly. The output shaft of the motor 106 is directly or indirectly coupled to both the first cam 108 and the second cam 110. In particular, the first cam 108 and the second cam 110 may both be disposed on the output shaft of the motor 106, or both may be disposed on a common shaft indirectly driven by the motor 106 (e.g., via a gear). Each of the cams 108, 110 defines a different cam path that is engaged by a respective one of the cam followers 112, 114. Because the two cam paths are different, the motion induced in the cam followers 112, 114 is also different (for at least a portion of the rotation of the shaft). The first follower 112 is connected to the first set of blades 116, and the second follower 114 is connected to the second set of blades 116. Because the first cam follower 112 and the second cam follower 114 move in different ways for at least some of their motion cycles (due to the differences in the respective cam paths), the first set of blades 116 and the second set of blades 118 also move in different ways. It will be appreciated that because the two cam paths are driven to rotate together, the motion of the first set of blades and the second set of blades are not independent, but the motion of the first set of blades and the second set of blades is different (for at least a portion of the rotation of the shaft).

[0124] Thus, a single motor 106 is used to drive both sets of vanes 116, 118 within the vent to move in different manners, thereby allowing a variety of different air flow configurations to be achieved with a single motor.

[0125] In an alternative embodiment, no user interface 102, electronic controller 104 or electric motor 106 is provided, and instead, the first cam 108 and the second cam 110 are typically driven by a user manually actuated input device, such as a dial. In this case, the first cam 108 and the second cam 110 can still be mounted to a common shaft, but the common shaft is driven to rotate by the user manually manipulating the input device.

[0126] Reference Figure 3A and Figure 3B , provided above reference Figure 2 A schematic diagram of the structure of the internal components of the vent assembly is schematically described. In fact, Figure 3A and Figure 3B The components shown in the figure will be packaged into a housing and installed in a suitable location (behind the instrument panel 3) within the vehicle's cabin 2. As will be explained below, the vent is particularly well suited for installation within the instrument panel of the vehicle cabin, and most particularly directly in front of the driver, with the vehicle's steering wheel 6 disposed between the driver and the vent. A similar vent, also located within the instrument panel, may be provided in front of the front passenger position.

[0127] exist Figure 3A and Figure 3B , it can be seen that the vent assembly 200 includes a motor 206 having a common output shaft 207. A first cam wheel disc 208 and a second cam wheel disc 210 are each mounted to the common output shaft 207. The first cam wheel disc 208 and the second cam wheel disc 210 are parallel to each other and spaced apart from each other and in a radial plane relative to the shaft 207. Each cam wheel disc carries a cam track 209 and a cam track 211, respectively, on its planar surface facing the other of the cam wheel discs. That is, the cam wheel disc 208 has a cam track 209 defined on its surface facing the cam wheel disc 210, and the cam wheel disc 210 has a cam track 211 defined on its surface facing the cam wheel disc 208. The cam tracks 209, 211 define a cam path. A first cam follower 212 and a second cam follower 214 are operably coupled to the cam wheel discs 208 and 210, respectively. More specifically, the first cam follower 212 is provided at one end thereof with a pin 213 that engages with the cam track 209 of the first cam wheel disc 208. Similarly, the second cam follower 214 is provided at one end thereof with a pin 215 that engages with the cam track 211 of the second cam wheel disc 210.

[0128] The ends of the first cam follower 212 and the second cam follower 214 carrying the pins 213 and 215, respectively, are arranged (and captured) between the two cam wheel discs 208 and 210. That is, with the pins 213 and 215 engaging the respective cam tracks, the portions of the cam followers 212 and 214 in the vicinity of the pins 213 and 215 (and in particular between the cam wheel discs 208 and 210) slidably abut each other, so that the cam followers 212 and 214 can move relative to each other (in a constrained manner) without the pins 213 and 215 being disengaged from the tracks 209 and 211. The first cam follower 212 and the second cam follower 214 are constrained (by means not shown) to move only along the longitudinal axis of the cam followers, which constitutes the direction of action of the cam followers. This direction of action is most effectively radial relative to the axis of rotation of the shaft 207. Therefore, the permitted direction of movement of the cam follower 212 and the permitted direction of movement of the cam follower 214 are parallel. This constraint of the movement of the cam followers 212, 214 can be achieved by a housing (not shown) in which the assembly is disposed. The first cam follower 212 is connected to a set of blades 216 at a position substantially away from the pin 213. In particular, the connection is between the first cam follower 212 and each blade 215 in the set of blades 216. Each blade 215 is rotatably mounted to the interior of the housing by a corresponding pivot 217. When the first cam follower 212 moves along its longitudinal axis, the first cam follower displaces the rod 253 connected to the distributor rod 255, which itself is connected to all blades 251 (at a position on the blade at a distance from the pivot 217). This enables the blades 251 to rotate around the pivot 217, and thus defines different angles within the portion of the vent occupied by the blades 216. This allows the air flow through this portion of the vent to leave the vent in different directions. Similarly, the second cam follower 214 is also connected to the rod 263 and displaces the rod 263 when the second cam follower 214 moves along its longitudinal axis. The rod 263 is connected to the distributor rod 265, which itself is connected to each blade 261 of the second set of blades 218. The distributor rod 265 is connected to the blade 261 at a position on the blade at a distance from the pivot 219. This enables the blade to rotate about the pivot 219 and thus define different angles within the portion of the vent occupied by the set of blades 218. This enables the air flow through this portion of the vent to leave the vent in different directions. Since the two different portions of the vent, respectively occupied by the first set of blades 216 and the second set of blades 218, can direct the air in different directions (away from each other), the air flow from the vent can be controlled very flexibly.

[0129] It will be understood from the above that the inner and outer (or in other words, left and right) vertical blades are separate and can be controlled individually (but not independently). Therefore, in addition to the fully forward (neutral), left and right air flow directions provided by traditional vents, additional modes can also be provided. This includes a divergent mode in which the air is directed away from the center of the vent, which is suitable for aiming at a higher part and missing the driver's or passenger's head for a general cooling mode, and avoids drying the user's eyes or feeling the air flow. This also includes a focused mode in which the air is aimed directly at the center of the vent, which is suitable for aiming directly at the face for rapid cooling, while giving the greatest opportunity to miss the obstruction caused by the steering wheel and the hands on the steering wheel, and also reducing the cold air flowing to the hands.

[0130] Compared to the arrangement of the prior art, providing a focused pattern makes it possible to direct the air flow from both sides toward the center of the vent so that the air flow can plume to the face to the greatest extent for rapid cooling on both the driver's side and the passenger's side. On the driver's side, this also minimizes the air flow blocked by the steering wheel and / or the user's hands on the steering wheel. This is conducive to increasing the flow of cool air to the face and away from the hands to avoid getting the hands cold. By providing two circular cam wheels rotating on a motor, each cam wheel drives a separate pin on the cam follower drive rod, so that the two rods can always be controlled by one motor. This also ensures that no mechanical crossover is required. In addition, two complete cam wheels with annular cam paths rotating on the motor drive separate pins on the drive rod, so that the motor can rotate clockwise or counterclockwise to reach the desired position, thereby reducing the time required to achieve the desired air flow direction.

[0131] Reference Figure 4 and Figure 5 , showing five different air flow configurations that can be achieved using the present technology (see also Table 1 above). In configurations A, D (neutral), both the first set of blades 216 and the second set of blades 218 are parallel to each other and substantially perpendicular to the output face of the vent 400. This causes the air flow from the vent to be perpendicular to the face of the vent and generally toward the driver (e.g. Figure 4(A, D), wherein the vent 400 is behind the steering wheel 402), or alternatively toward the front passenger position in the vehicle cabin. In configuration E (focused), the first set of blades 216 and the second set of blades 218 are angled approximately toward each other, so that the air flow from the corresponding portion occupied by the first set of blades 216 and the second set of blades 218 of the vent converges to form a focused, highly directional air flow toward the driver (for example). This is particularly beneficial because it guides air through the steering wheel and guides air between the driver's hands and arms and onto the driver's face and body. Conventionally, since the steering wheel, the driver's arms and hands represent significant obstacles when the vents are set on both sides of the steering wheel, it is difficult or impossible to achieve this level of directionality to the driver. In configuration C (divergent), the first set of blades 216 and the second set of blades 218 are angled approximately away from each other, so that the air flow from the corresponding portion occupied by the first set of blades 216 and the second set of blades 218 of the vent diverges. In this case, as in the case of configuration E, the air flow generally avoids the steering wheel and the driver's arms and hands, but in contrast to configuration E, the air flow is not directed onto the driver, but rather is directed around the driver to more generally cool the vehicle cabin. In configuration B (inboard), the first set of blades 216 and the second set of blades 218 are parallel to each other and angled toward a first side of the vent so that the air flow from the corresponding portions of the vent occupied by the first set of blades 216 and the second set of blades 218 exit the vent in the same direction to provide cooling to the first side of the vent in the vehicle cabin. Similarly, in configuration F (outboard), the first set of blades 216 and the second set of blades 218 are parallel to each other and angled toward a second side (opposite to the first side) of the vent so that the air flow from the corresponding portions of the vent occupied by the first set of blades 216 and the second set of blades 218 exit the vent in the same direction to provide cooling in the vehicle cabin at the second side of the vent.

[0132] Figure 5 shows how the rotation of the motor and thus the rotation of the two cam wheels can generate a reference Figure 4 and the different configurations described in Table 1 above. Figure 5 In FIG. 5 , an illustrative output shaft position of motor 206 is indicated by line 510. The positions of rails 209, 211 are also shown in FIG. Figure 5 It can be seen that when the output shaft of the motor rotates (such as Figure 5The tracks / cam paths 209, 211 rotate with the output shaft of the motor as it passes through the various stages (progressively counterclockwise as shown in FIG. 1 , although clockwise rotation is possible as discussed elsewhere). Where the cam paths 209, 211 coincide on the axis of the cam followers 212, 214, the vanes 251, 261 adopt the same angular orientation. As the output shaft rotates counterclockwise (as viewed), the vent configuration is shown as gradually changing through stages A to F. Figure 5 At stage A in the output shaft, the output shaft is at the initial position (0°). At this rotational position of the output shaft, the two sets of blades are parallel and in the neutral position, corresponding to Figure 4 The motor 206 then rotates 45° at stage B, corresponding to an angle of 315°. Here, the two sets of blades are still parallel, but are now angled to direct air out to one side of the vent, corresponding to Figure 4 The motor 206 then rotates another 90° at stage C, corresponding to an angle of 225°. Here, the two sets of blades are angled away from each other, corresponding to Figure 4 Then, the motor 206 rotates another 45° at stage D, corresponding to an angle of 180°. Here, the two sets of blades are parallel again and in a neutral position, corresponding to Figure 4 The motor then rotates another 45° at stage E, corresponding to an angle of 135°. Here, the two sets of blades are angled toward each other, corresponding to Figure 4 The motor then rotates another 90° at stage F, corresponding to an angle of 45°. Here, the two sets of blades are parallel again, but are now angled to direct the air out the other side of the vent (compared to stage B). This corresponds to Figure 4 After completing the rotation, the motor can then move back to the initial position of phase A, thereby restoring the neutral configuration.

[0133] From this, it will be understood that when the motor (and its output shaft) rotates, the two sets of blades move. For certain parts of the rotation, such as between phase A and phase B and between phase F and phase A, the two sets of blades may move in the same way, e.g., remain parallel and change direction together. For other parts of the rotation, such as between phase B and phase C, between phase C and phase D, between phase D and phase E, and between phase E and phase F (and in the opposite direction), the two sets of blades move in different ways, resulting in relative motion (change in relative angle) between the blades.

[0134] For the sake of completeness, Figure 5The final orientation of the blades at two angles of motor rotation not shown in the figure, namely 270 degrees and 90 degrees (positions 3 and 7 in Table 1), would not normally be used because it would result in one set of blades being in a neutral position and the other set of blades directing the air into a neutral forward flow or away from a neutral position, which would not have much application. Possibly, one set of blades being in a neutral position and the other set of blades directing the air away from a neutral position might have application for directing a portion of the flow through the steering wheel at the driver's face and the remainder being directed into the body of the vehicle cabin, but this would lose the advantage of, for example, Figure 4 The benefit of the two air streams colliding and being focused through the steering wheel and away from the hands holding the steering wheel is evident in (E).

[0135] It will be appreciated that the motor 206 can be driven in either direction. For any given desired vent configuration, this can be achieved by either clockwise or counterclockwise rotation of the output shaft of the motor 206. However, depending on the current air flow configuration, the amount of rotation required may not be the same in the two rotational directions. Therefore, it is desirable to select the direction of motor rotation that will require the minimum amount of rotation (angle) based on the current and desired vent configurations, because (assuming a fixed motor speed) this can be achieved more quickly and with the fewest intermediate (and unselected) stages. The controller is configured to select the motor rotation direction and the amount of motor rotation based on the current rotational position (current stage) and the desired vent configuration. This can be achieved, for example, by means of a lookup table. In Figure 5 In the example, two neutral positions are provided (corresponding to Figure 4 Configuration A in ). From the first neutral position (stage A), the inboard or outboard airflow direction ( Figure 4 Configurations B and F in the embodiment can be achieved without any intermediate stages by rotating the motor 45 degrees. From the second neutral position (stage D), converging (configuration E) or diverging (configuration C) air flows can be achieved without any intermediate stages.

[0136] With this approach, by using a full rotation of the actuator (motor), any desired air flow direction can be achieved in less time than with a conventional cam-controlled actuator. In particular, by appropriately defining the cam path, all desired air flow directions are provided at different rotational positions of the actuator and the cam. Specifically, a different cam path is provided for each side of a (set of) blades, and the different cam paths are driven by a single actuator, which enables a robust and time-saving movement of the blades to reach the position desired by the customer. It will be understood that advantageously, even a rotation of up to 180° is required to reach a position (by utilizing two directions of rotation).

[0137] Different cam paths can be shown in the figure, especially Figure 3A and Figure 5One of the paths (the first path defined by track 211) may have two orthogonal planes 275, 277 about its axis of rotation (and mirror symmetry - see Figure 5 (A)), while the second path defined by track 209 may not have rotational symmetry (and one plane 279 of mirror symmetry). The first path may include two substantially equal sized protrusions at opposite sides of the path's axis of rotation, and the second path may include a generally elliptical shape with a single side protrusion that is smaller than an elliptical shape. The planes of symmetry 275, 277 of the first path 211 are each offset by 45 degrees relative to the plane of symmetry 279 of the second path 209. Collectively, these shaped cam paths are capable of providing the various configurations described herein. The shape of the cam path defines the sequence of "modes" (blade configurations) that a customer or motor can cycle through.

[0138] Reference Figure 6 as well as Figure 2 , a schematic flow chart explaining the process of vent adjustment using the above-described present device is provided. At step S1, a user interacts with the user interface 102 to select a desired vent configuration. This may, for example, include interacting with a touch screen display or manipulating a physical input control, such as a switch or dial. At step S2, the controller 104 determines the direction and amount of rotation required to achieve the desired vent configuration based on the current rotational position of the motor output shaft and the cam wheel. At step S3, the motor is typically driven at a predetermined speed until the output shaft, on which the cam wheel is disposed, has been rotated to the correct angle for the desired vent configuration. At step S4, the motor stops and the adjustment process ends. Repeat the next time the user selects a different vent configuration Figure 6 process.

[0139] It will be appreciated that there is a substantial overlap between the first embodiment and the second and third embodiments described below, and that features of the following embodiments may be used in combination with the first embodiment where such features are technically compatible.

By means of the engagement between the guide block 5.2 and the guide groove 6.2, the first drive rod 11.5 and the second drive rod 11.6 can guide each other, so that the first drive rod 11.5 and the second drive rod 11.6 can only perform linear motion along the sliding groove and the guide groove 6.2.

[0145] The first driving rod 11.5 and the second driving rod 11.6 can respond to the actions of the first cam groove 3.1 and the second cam groove 4.1 to directionally drive the first sheet member group 11.1 and the second sheet member group 11.2 to swing.

The first concentrated air output point 3.11, the first rightward air output point 3.12, the first leftward air output point 3.13 and the first diffused air output point 3.14 are arranged in an annular manner. The first concentrated air output point 3.11, the first rightward air output point 3.12, the first leftward air output point 3.13 and the first diffused air output point 3.14 divide the first cam groove 3.1 into four sections.

The second cam groove 4.1 is annular in shape as a whole. The second concentrated air output point 4.11, the second rightward air output point 4.12, the second leftward air output point 4.13 and the second diffused air output point 4.14 are arranged in an annular manner. The second concentrated air output point 4.11, the second rightward air output point 4.12, the second leftward air output point 4.13 and the second diffused air output point 4.14 divide the first cam groove 3.1 into four sections. The second cam groove 4.1 is provided with a first travel section 4.15 between the second concentrated air output point 4.11 and the second rightward air output point 4.12, a second travel section 4.16 is provided between the second rightward air output point 4.12 and the second leftward air output point 4.13, a third travel section 4.17 is provided between the second leftward air output point 4.13 and the second diffused air output point 4.14, and a fourth travel section 4.18 is provided between the second diffused air output point 4.14 and the second concentrated air output point 4.11.

[0148] The distances from the second concentrated air output point 4.11, the second rightward air output point 4.12, the second leftward air output point 4.13 and the second diffused air output point 4.14 to the rotation center of the second rotating disk 11.4 in the rotating assembly are S11.1, S11.2, S11.3 and S11.4 respectively, where S11.1=S11.2>S11.3=S11.4.

[0149] When the rotating assembly rotates, the first driving block 5.1 is driven to pass through the first concentrated air output point 3.11, the first rightward air output point 3.12, the first leftward air output point 3.13 and the first diffused air output point 3.14 in sequence, and the second driving block 6.1 is driven to pass through the second concentrated air output point 4.11, the second rightward air output point 4.12, the second leftward air output point 4.13 and the second diffused air output point 4.14 in sequence.

When the first driving block 5.1 is at the first leftward air output point 3.13, the second driving block 6.1 is at the second leftward air output point 4.13. When the first driving block 5.1 is at the first diffuse air output point 3.14, the second driving block 6.1 is at the second diffuse air output point 4.14.

[0150] Reference Figures 14 to 17 During the rotation of the rotating assembly, the motion states of the first air flow guiding sheet member 1.1 and the second air flow guiding sheet member 2.1 are as follows:

[0151] S11.1, when the first driving block 5.1 is at the first concentrated air output point 3.11, the first air flow guide sheet 1.1 is driven to tilt toward the second air flow guide sheet 2.1 (i.e., tilted to the left), and the second driving block 6.1 is at the second concentrated air output point 4.11, and the second air flow guide sheet 2.1 is driven to tilt toward the first air flow guide sheet 1.1 (i.e., tilted to the right). In this case, the first air flow guide sheet 1.1 and the second air flow guide sheet 2.1 cooperate to achieve concentrated air output.

[0152] S11.2. The rotating assembly continues to rotate such that when the first drive block 5.1 switches from the first centralized air output point 3.11 to the first rightward air output point 3.12 along the first track section 3.15, the first track section 3.15 engages with the first drive block 5.1. Since L2 > L1, the first drive block 5.1 and the first drive rod 11.5 are driven to move away from the rotation center of the first rotating disk 11.3 in the rotating assembly. Accordingly, the first drive rod 11.5 drives the first air flow guiding flap 1.1 to swing rightward such that when the first drive block 5.1 is at the first rightward air output point 3.12, the first air flow guiding flap 1.1 is inclined rightward.

[0153] The second drive block 6.1 switches from the second centralized air output point 4.11 to the second rightward air output point 4.12 along the first travel section 4.15, and the second travel section 4.15 engages with the second drive block 6.1. Since S11.1 = S11.2, the first travel section 4.15 is idle, and the positions of the second drive block 6.1 and the second drive rod 11.6 remain unchanged. Accordingly, the second air flow guiding flap 2.1 remains inclined toward the first air flow guiding flap 1.1 (i.e., inclined rightward). In this case, the first air flow guiding flap 1.1 and the second air flow guiding flap 2.1 cooperate to achieve rightward air output.

[0154] S11.3. The rotating assembly continues to rotate such that when the first drive block 5.1 switches from the first rightward air output point 3.12 to the first leftward air output point 3.13 along the second track section 3.16, the second track section 3.16 engages with the first drive block 5.1. Since L3 < L2, the first drive block 5.1 and the first drive rod 11.5 are driven to move toward the rotation center of the first rotating disk 11.3 in the rotating assembly. Accordingly, the first drive rod 11.5 drives the first air flow guiding flap 1.1 to swing leftward such that when the first drive block 5.1 is at the first leftward air output point 3.13, the first air flow guiding flap 1.1 is inclined leftward.

[0155] The second drive block 6.1 switches from the second right air output point 4.12 to the second left air output point 4.13 along the second travel section 4.16, and the second travel section 4.16 engages with the second drive block 6.1. Since S11.3 < S11.2, the second drive block 6.1 and the second drive rod 11.6 are driven to move towards the rotation center of the second rotating disk 11.4 in the rotating assembly. Accordingly, the second drive rod 11.6 drives the second air flow guiding sheet 2.1 to swing leftward, such that when the second drive block 6.1 is at the second left air output point 4.13, the second air flow guiding sheet 2.1 inclines leftward. In this case, the first air flow guiding sheet 1.1 and the second air flow guiding sheet 2.1 cooperate to achieve left air output.

[0156] S11.4, the rotating assembly continues to rotate such that when the first drive block 5.1 switches from the first left air output point 3.13 to the first diffused air output point 3.14 along the third track section 3.17, the third track section 3.17 engages with the first drive block 5.1. Since L4 > L3, the first drive block 5.1 and the first drive rod 11.5 are driven to move away from the rotation center of the first rotating disk 11.3 in the rotating assembly. Accordingly, the first drive rod 11.5 drives the first air flow guiding sheet 1.1 to swing rightward, such that when the first drive block 5.1 is at the first diffused air output point 3.14, the first air flow guiding sheet 1.1 inclines rightward.

[0157] The second drive block 6.1 switches from the second left air output point 4.13 to the second diffused air output point 4.14 along the third travel section 4.17, and the third travel section 4.17 engages with the second drive block 6.1. Since S11.4 = S11.3, the third travel section 4.17 is idle. When the second drive block 6.1 reaches the second diffused air output point 4.14, the positions of the second drive block 6.1 and the second drive rod 11.6 remain unchanged, such that the second air flow guiding sheet 2.1 remains inclined towards the first air flow guiding sheet 1.1 (i.e., inclines leftward). In this case, the first air flow guiding sheet 1.1 and the second air flow guiding sheet 2.1 cooperate to achieve diffused air output.

[0158] S5, the rotating assembly continues to rotate such that when the first driving block 5.1 switches from the first diffused air output point 3.14 to the first concentrated air output point 3.11 along the fourth track section 3.18, the fourth track section 3.18 engages with the first driving block 5.1. Since L1 < L4, the first driving block 5.1 and the first driving rod 11.5 are driven towards the center of rotation of the first rotating disk 11.3 in the rotating assembly. Accordingly, the first driving rod 11.5 drives the first air flow guiding flap 1.1 to swing leftward such that when the first driving block 5.1 is at the first concentrated air output point 3.11, the first air flow guiding flap 1.1 is inclined leftward.

[0159] The second driving block 6.1 switches from the second diffused air output point 4.14 to the second concentrated air output point 4.11 along the fourth travel section 4.18, and the fourth travel section 4.18 engages with the second driving block 6.1. Since S11.1 > S11.4, the second driving block 6.1 and the second driving rod 11.6 are driven away from the center of rotation of the second rotating disk 11.4 in the rotating assembly. Accordingly, the second driving rod 11.6 drives the second air flow guiding flap 2.1 to swing rightward such that the second air flow guiding flap 2.1 is inclined rightward. In this case, the first air flow guiding flap 1.1 and the second air flow guiding flap 2.1 cooperate to achieve concentrated air output. In this case, the process returns to S11.1, thereby completing one movement cycle.

[0160] In this embodiment, the air output device further includes an electric actuator 11.7. The actuator 11.7 is drivingly connected to the rotating assembly so as to drive the rotating assembly to perform circular rotation, thereby achieving automatic air output. Additionally, in another embodiment, the rotation of the rotating assembly can also be manually driven.

[0161] In the air output device of the present invention, a first cam groove 3.1 and a second cam groove 4.1 are provided. During use, the rotating assembly rotates, the first cam groove 3.1 engages with the first drive block 5.1 to define the movement path of the first drive block 5.1, and the second cam groove 4.1 engages with the second drive block 6.1 to define the movement path of the second drive block 6.1, thereby enabling the first drive rod 11.5 and the second drive rod 11.6 to move. The first drive rod 11.5 drives the first air flow guide sheet 1.1 to swing when moving. The second drive rod 11.6 drives the second air flow guide sheet 2.1 to swing when moving. When the first air flow guide sheet 1.1 and the second air flow guide sheet 2.1 swing, the first air flow guide sheet 1.1 and the second air flow guide sheet 2.1 can swing outward in opposite directions to achieve diffuse air output, the first air flow guide sheet 1.1 and the second air flow guide sheet 2.1 can swing inward in opposite directions to achieve concentrated air output, and the first air flow guide sheet 1.1 and the second air flow guide sheet 2.1 can swing in the same direction to adjust the air output angle. By using one rotating assembly, two groups of air flow guide sheets can be adjusted, thereby achieving a simple structure and easy adjustment, thereby reducing the number of components, cost and overall size, and allowing the air output device to be easily arranged in the car. In addition, the rotating disk is configured to be positioned away from the air output area so that the air output is not affected. In addition, the respective other ends of both the first driving rod 11.5 and the second driving rod 11.6 extend toward the air output region along the X direction, so that the air output region is less affected, thereby ensuring the ultimate air output performance.

[0162] It will be appreciated that there is substantial overlap between the second embodiment and the first and third embodiments described above and below, and that features of the following embodiments may be used in conjunction with the first embodiment where such features are technically compatible.

[0163] like Fig.18 As shown in , the air outlet sheet member adjustment mechanism of the present embodiment includes a first sheet member group 10 , a second sheet member group 20 , a first shift fork 30 , a second shift fork 40 , a first drive member 50 , a second drive member 60 and a power device 70 .

[0164] The first sheet element group 10 comprises a plurality of air flow guiding sheet elements 100 arranged at intervals along a first direction and arranged in a rotatable manner in the air outlet. All the air flow guiding sheet elements 100 in the first sheet element group 10 are connected by means of a first connecting rod 11 for synchronous rotation. It will be understood that by transmission connection, it means that the air flow guiding sheet elements 100 in the first sheet element group 10 are connected so that the movement of one sheet element is transmitted to other sheets through the first connecting rod 11, thereby rotating synchronously. The first connecting rod 11 is hingedly connected to all the air flow guiding sheet elements 100 in the first sheet element group 10. The second sheet element group 20 comprises a plurality of air flow guiding sheet elements 100 arranged at intervals along a first direction and arranged in a rotatable manner in the air outlet. All the air flow guiding sheet elements 100 in the second sheet element group 20 are connected by means of a second connecting rod 21 for synchronous rotation. The second connecting rod 21 is hingedly connected to all the air flow guiding sheet elements 100 in the second sheet element group 20. The first lamellae group 10 and the second lamellae group 20 constitute vertical lamellae of the air outlet.

[0165] The first shift fork 30 is configured to move only in the first direction. The first shift fork 30 is connected to one of the air flow guide sheet members 100 in the first sheet member group 10. When moving in the first direction, the first shift fork 30 can drive the air flow guide sheet member 100 in the first sheet member group 10 to rotate. The second shift fork 40 is configured to move only in the first direction. The second shift fork 40 is connected to one of the air flow guide sheet members 100 in the second sheet member group 20. When moving in the first direction, the second shift fork 40 can drive the air flow guide sheet member 100 in the second sheet member group 20 to rotate.

[0166] The first drive member 50 is connected to the first shift fork 30. The first drive member 50 rotates to drive the first shift fork 30 to shift in the first direction. When shifting in the first direction, the first shift fork 30 can drive the air flow guide sheet 100 in the first sheet member group 10 to rotate, thereby adjusting the angle of the first sheet member group 10. The second drive member 60 is connected to the second shift fork 40. The second drive member 60 rotates to drive the second shift fork 40 to shift in the first direction. When shifting in the first direction, the second shift fork 40 can drive the air flow guide sheet 100 in the second sheet member group 20 to rotate, thereby adjusting the angle of the second sheet member group 20.

[0167] The power device 70 may be a motor. The power device 70 includes a drive shaft. The drive shaft is connected to the first drive member 50 and the second drive member 60. The power device 70 is used to drive the first drive member 50 and the second drive member 60 to rotate synchronously by means of the drive shaft. The rotation angle of the drive shaft includes a plurality of continuous rotation angle intervals, and the displacement amount and / or displacement direction of the first shift fork 30 and the second shift fork 40 are different in at least one rotation angle interval in the rotation angle intervals.

[0168] like Fig.19 and Fig. 22 As shown in , the first drive member 50 is provided with a first mounting surface parallel to the first direction. The first mounting surface is provided with a first track groove portion 51. The first track groove portion 51 has a groove bottom and two side walls. The first shift fork 30 is provided with a first connecting portion 31. The first connecting portion 31 is fixedly connected to the first shift fork 30. The first connecting portion 31 is fixedly connected to the first shift fork 30. The first connecting portion 31 is inserted into and connected to the first track groove portion 51. The first shift fork 30 is parallel to the first mounting surface. The first connecting portion 31 is movable in the first track groove portion 51. When the first drive member 50 rotates, the side wall of the first track groove portion 51 pushes the first connecting portion 31, so that the first shift fork 30 moves along the first direction.

[0169] like Fig. 20 and Fig.23 As shown in , the second drive member 60 is provided with a second mounting surface parallel to the first direction. The second mounting surface is provided with a second track groove portion 61. The second track groove portion 61 has a groove bottom and two side walls. The second shift fork 40 is provided with a second connecting portion 41. The second connecting portion 41 is fixedly connected to the second shift fork 40. The second connecting portion 41 is inserted into and connected to the second track groove portion 61. The second shift fork 40 is parallel to the second mounting surface. The second connecting portion 41 is movable in the second track groove portion 61. When the second drive member 60 rotates, the side wall of the second track groove portion 61 pushes the second connecting portion 41, so that the second shift fork 40 moves along the first direction.

[0170] The extension tracks of the first track groove portion 51 and the second track groove portion 61 are different, so that when the first drive member 50 and the second drive member 60 rotate synchronously, the movement displacement amount and / or displacement direction of the first shift fork 30 and the second shift fork 40 in the first direction are different, and therefore the angles of the air flow guide sheet members in the first sheet member group 10 and the second sheet member group 20 are different.

[0171] The transmission axes of the first drive member 50 and the second drive member 60 coincide with the axis of the drive shaft of the power device 70 .

[0172] like Fig. 22 and Fig.23 As shown in , the first limiting portion 52 is fixed on the first driving member 50, is in the shape of a sleeve and has a non-circular structure, and the second limiting portion 62 is fixed on the second driving member 60, is in the shape of a sleeve and has a non-circular structure. The second limiting portion 62 and the first limiting portion 52 have the same shape, but have different sizes. The size of the first limiting portion 52 is larger than the size of the second limiting portion 62. The first limiting portion 52 and the second limiting portion 62 are sleeved with each other and are limited in the circumferential direction. The drive shaft of the power device 70 is connected to the first driving member 50 to drive the first driving member 50 to rotate, and the first driving member 50 drives the second driving member 60 to rotate synchronously.

[0173] like Fig.19 and Fig. 20 As shown in , the protrusion 32 is fixed on the first shift fork 30 and is provided with a slide groove 321 extending in the first direction. The slide groove 321 passes through the two ends of the protrusion 32. The cross section of the slide groove 321 is triangular. A slider 42 whose shape matches the shape of the slide groove 321 is fixed on the second shift fork 40. The cross section of the slider 42 is triangular. The first shift fork 30 and the second shift fork 40 are parallel to each other and close to each other. The slider 42 is slidably arranged in the slide groove 321. When the displacement of the first shift fork 30 and the second shift fork 40 in the first direction is different, the slider 42 can slide along the slide groove 321, so that the first shift fork 30 and the second shift fork 40 move relative to each other. In this way, the first shift fork 30 and the second shift fork 40 do not need to be provided with sliding seats respectively. The first shift fork 30 and the second shift fork 40 jointly form a sliding structure, thereby reducing components and simplifying the structure.

[0174] like Fig.19 , Fig. 20 and Fig.21 As shown in FIG. 1 , the first shift fork 30 is provided with a first recess 33, and one of the air flow guide sheet members 100 in the first sheet member group 10 has a drive rod portion 11.110 extending into the first recess 33. When the first shift fork 30 moves in the first direction, the first shift fork 30 applies a thrust to the drive rod portion 11.110 via the first recess 33 to push the air flow guide sheet member 100 to rotate. In this case, the drive rod portion 11.110 slides relatively in the first recess 33 along the depth direction of the first recess 33, so that the first shift fork 30 and the air flow guide sheet member 100 are not easily stuck to each other.

[0175] The second shift fork 40 is provided with a second recess 43, and one of the air flow guide sheet members 100 in the second sheet member group 20 has a drive rod portion 11.110 extending into the second recess 43. When the second shift fork 40 moves in the first direction, the second shift fork 40 applies a thrust to the drive rod portion 11.110 via the second recess 43 to push the air flow guide sheet member 100 to rotate. In this case, the drive rod portion 11.110 slides relatively in the second recess 43 along the depth direction of the second recess 43, so that the second shift fork 40 and the air flow guide sheet member 100 are not easily stuck to each other.

[0176] The electric air outlet assembly in this embodiment includes an air outlet flap adjustment mechanism.

[0177] The vehicle in this embodiment includes an electric air outlet assembly.

[0178] When the air outlet flap adjustment mechanism of the present invention works, if the driving shaft of the power device does not rotate, the air flow guide flaps in the first flap group 10 and the second flap group 20 are both at 0 degrees, and this is the initial angle of the first flap group 10 and the second flap group 20.

[0179] When the output shaft of the power device rotates from 0 degrees to 45 degrees, all of the air flow guide sheet members in the first sheet member group and the second sheet member group rotate 40 degrees to the right from the initial angle.

[0180] When the output shaft of the power device continues to rotate from 45 degrees to 90 degrees, the air flow guide sheets in the first sheet member group do not move, and all the air flow guide sheets in the second sheet member group rotate rightward from 40 degrees to 0 degrees.

[0181] When the output shaft of the power device continues to rotate from 90 degrees to 135 degrees, the air flow guide sheets in the first sheet member group do not move, and all the air flow guide sheets in the second sheet member group rotate leftward from 0 degrees to 40 degrees.

[0182] When the output shaft of the power device continues to rotate from 135 degrees to 180 degrees, all the air flow guide sheets in the first sheet member group rotate rightward from 40 degrees to 0 degrees, and all the air flow guide sheets in the second sheet member group rotate leftward from 40 degrees to 0 degrees.

[0183] When the output shaft of the power device continues to rotate from 180 degrees to 225 degrees, all the air flow guide sheets in the first sheet member group rotate 40 degrees from 0 degrees to the left, and all the air flow guide sheets in the second sheet member group rotate 40 degrees from 0 degrees to the right.

[0184] When the output shaft of the power device continues to rotate from 225 degrees to 270 degrees, the air flow guide sheets in the first sheet member group do not move, and all the air flow guide sheets in the second sheet member group rotate rightward from 40 degrees to 0 degrees.

[0185] When the output shaft of the power device continues to rotate from 270 degrees to 315 degrees, the air flow guide sheets in the first sheet member group do not move, and all the air flow guide sheets in the second sheet member group rotate 40 degrees to the left from 0 degrees.

[0186] When the output shaft of the power device continues to rotate from 315 degrees to 360 degrees, all the air flow guide sheets in the first sheet member group rotate leftward from 40 degrees to 0 degrees, and all the air flow guide sheets in the second sheet member group rotate leftward from 40 degrees to 0 degrees.

[0187] The angular relationship between the first sheet member group 10 and the second sheet member group 10 can be adjusted by changing the tracks of the first track groove portion 51 and the second track groove portion 61 .
