Description

Technical field of the invention

[0001] The present invention relates to an air outlet. More specifically, but without limitation, the present disclosure relates to an air guide outlet. Background of the invention

[0002] In the field of vehicle ventilation, the use of air vents is essential for providing controlled air circulation within the vehicle's confines. Throughout the development of motor vehicles, air vents have always served as important components for improving passenger comfort by directing and regulating airflow within the passenger compartment.

[0003] Air ducting diffusers are well-known in the field of air conditioning systems, particularly in automotive applications. In conventional air ducting diffusers, the airflow is typically split into two or four independent air channels or ducts. The air exiting these channels or ducts forms counter-current airflows that interact, thus generating the ducting effect required for airflow direction. However, this design has certain limitations. Dividing the airflow into separate channels or ducts automatically reduces the available cross-sectional area through which the air can flow. This reduction in space increases frictional losses, especially when the airflow interacts with the walls of the channels or ducts, leading to inefficiencies in airflow distribution.

[0004] Furthermore, in some conventional designs, the functional elements responsible for controlling the direction of the airflow, such as guide vanes or louvers, are located close to the air outlet. This proximity of the functional elements to the air outlet leads to increased noise near the outlet when the airflow becomes more turbulenced. The suboptimal acoustic properties of the air outlet can cause discomfort for users.

[0005] Conventional functional elements for controlling airflow direction, such as steering vanes or louvers, offer airflow direction control with limited adjustability of the airflow distribution. This limited adjustability leads to an imprecise airflow distribution.

[0006] Many conventional air duct outlets comprise a rectangular recess that creates two airflows exiting the outlet. These two airflows interact along a line spaced downstream of the outlet, where the air duct control takes place. This type of air duct control allows for control of the resulting airflow direction only along one dimension within a plane. Therefore, the advantages of air duct control over conventional methods can only be realized in one plane, while conventional airflow control methods are employed in the secondary plane.

[0007] The present invention aims to provide means that can be used to address some or all of the problems mentioned above. Brief description of the invention

[0008] According to a first aspect of the invention, an air duct outlet is provided. The air duct outlet can comprise an air duct having an air inlet and an air outlet. The air duct outlet can comprise a body that is positioned at least partially within the air duct. The body can be positioned between the air inlet and the air outlet. The body can be configured to prevent airflow through it. The body can be configured to allow airflow through a passage defined between an inner surface of the air duct and an outer surface of the body. The passage can extend substantially around the entire circumference of the body. The air duct outlet can comprise at least one directional control element. The at least one directional control element can be positioned between the air inlet and the body.The at least one directional control element can be located at a distance from the body. The at least one directional control element can be operated to change the direction of the airflow flowing from the air inlet to the body, thereby controlling the direction of the airflow from the air outlet. The at least one directional control element can include at least one nozzle that is movably mounted in the air duct.

[0009] The air ducting system revealed here offers remarkable advantages that improve both the user experience and operational efficiency. By strategically placing one or more directional controls away from the air outlet (more specifically, by placing one or more directional controls behind and away from the user), noise levels to which users near the outlet are exposed are significantly reduced. This design effectively addresses the acoustic impact associated with operating the directional controls. By positioning the directional controls further away from the user, the resulting operating noise is minimized.

[0010] Furthermore, the body positioned within the air duct is configured to minimize air turbulence in the stream exiting the outlet. The body also promotes airflow convergence at specific points relative to the user, enabling more precise and targeted airflow direction control.

[0011] Furthermore, using a nozzle as an air deflector allows for a wide range of directional movement, enabling more precise changes in airflow direction. As the air flows through the duct, the nozzle influences its trajectory, causing it to adhere to and follow the contours of the nozzle's inner surface. Therefore, using a nozzle provides an aerodynamically efficient solution, utilizing fluid dynamics to precisely guide the airflow as it exits the nozzle and is directed towards the vehicle body. Additionally, using a nozzle provides a robust air deflector that is less susceptible to vibrations and vehicle turbulence.

[0012] The air duct may be suitable for use in a vehicle, particularly a motor vehicle. It should be noted that, although the following discussion refers to the air duct in the context of a vehicle, the versatility of this air duct design extends beyond automotive applications. This air duct can be installed in various locations and environments. For example, it could be seamlessly integrated into residential heating, ventilation, and air conditioning (HVAC) systems to provide targeted airflow settings in living spaces. Furthermore, the air duct could be used in commercial or industrial settings.

[0013] The air duct of the air outlet can comprise an essentially tubular structure. Depending on the requirements of the specific application, the air duct can be of any suitable size or length. The air inlet can be connected to a vehicle HVAC system. In some embodiments, the vehicle HVAC system can be configured to control the intensity of the airflow entering the air inlet. The air duct may not be limited to a straight configuration and can include both straight and curved sections if necessary to accommodate design or spatial constraints of the system in which it is implemented.

[0014] In some embodiments, the body may be positioned entirely within the air duct. In other embodiments, at least a portion of the body may protrude from the air outlet. The body may not extend through the entire air duct. The body may be positioned closer to the air outlet than to the air inlet. In some embodiments, the body may be flush with the air outlet. In some embodiments, the body may be positioned less than 0.5 cm, less than 1 cm, less than 2 cm, less than 3 cm, less than 4 cm, less than 5 cm, less than 6 cm, or less than 10 cm from the air outlet. Preferably, in automotive applications, the body may be positioned less than 5 cm from the air outlet. More preferably, the body may be positioned less than 2 cm from the air outlet.

[0015] The body can be made of an airtight material. For example, the body can be made of plastic or metal. The body can have a continuous outer surface that prevents airflow through it. For example, the body might not have any holes or openings. In this way, the body's structure prevents air from flowing through its interior. Instead, the airflow is directed around the body through a defined passage between the outer surface of the body and the inner surface of the air duct.

[0016] This configuration effectively reduces friction losses and minimizes air turbulence, as the airflow is guided unimpeded around the body. By preventing air from flowing through the interior of the body, and because the mass flow is not interrupted by leaks or undirected airflow, further directional control is achieved, even in extreme orientations. This maintains a streamlined flow, reducing disturbances and friction losses in the air duct. As a result, the overall efficiency of the ventilation system is improved.

[0017] The at least one directional control element can be separate from the body. The at least one directional control element may not be connected to the body.

[0018] The body can have a tapered cross-section towards the air inlet. This tapering can be perpendicular to the axis of the air duct. More specifically, the cross-sectional area of ​​the body can decrease progressively along its length towards the air inlet. The tapering can be uniform or uneven. The tapering could have various geometric shapes. For example, it could be conical or frustoconical. The body can have its largest cross-section near the air outlet and its smallest cross-section towards the air inlet.

[0019] The tapered cross-section of the body reduces air turbulence in the duct by providing a more aerodynamically efficient surface for the airflow to follow. As the air gradually decreases, disturbances are minimized as it flows through the duct, allowing for a smoother transition. This reduction in turbulence contributes to quieter operation, as less turbulent air results in lower noise levels generated by the ventilation system.

[0020] The body can comprise an essentially conical structure. In some embodiments, the body can comprise a cone on a hemispherical base, a truncated cone, or an asymmetrical cone.

[0021] The conical structure can have a substantially elliptical base. The conical structure can have a substantially circular base. The conical structure can taper uniformly (e.g., the reduction in cross-sectional area follows a consistent gradient along the length of the body) or unevenly (e.g., the constriction rate varies along different regions of the body) from the base to a tip. The base can be positioned closer to the air outlet than the air inlet. The tip of the conical structure can be positioned closer to the air inlet than the air outlet. In one embodiment, the tip of the conical structure can be rounded. In another embodiment, the tip can be pointed.

[0022] The conical structure of the body offers several aerodynamic advantages in air ducting. By tapering from a wider base to a narrower tip, the conical shape allows the airflow to flow smoothly around the body, thus reducing turbulence in the air flowing through the duct.

[0023] Furthermore, the conical structure of the body allows for airflow control in a circular / 360-degree profile, enabling the airflow exiting the air outlet to converge at a single point rather than along a linear axis. This configuration ensures that the airflow can be directed with greater precision, allowing for more effective and better-controlled airflow targeting specific areas or points of application.

[0024] In some embodiments, the base of the conical structure can be flat. In other embodiments, the base of the conical structure can include raised sections or protrusions on its surface.

[0025] A direction running from a center point of the base of the conical structure to a center point of the air outlet can define a longitudinal axis.

[0026] The body can be movable along its longitudinal axis with respect to the air outlet. In some embodiments, the air duct can extend generally along the longitudinal axis. In this embodiment, the airflow direction through the air duct can be substantially parallel to the longitudinal axis. In some embodiments, some sections of the air duct can deviate from the longitudinal axis. For example, the air duct can include curved or angled sections.

[0027] Advantageously, the air duct structure can deviate from the longitudinal axis to meet specific design constraints or functional requirements. More specifically, curved or angled sections can allow the air duct to be routed around obstacles or fit into confined spaces within a vehicle's dashboard while maintaining efficient airflow.

[0028] The cross-sectional area of ​​the air duct (the cross-sectional area in a direction perpendicular to an airflow direction at any point in the air duct) can vary along its length. For example, certain sections of the air duct can be wider or narrower to control the velocity or pressure of the airflow as it passes through the duct.

[0029] The body can be movable between a first position and a second position. In the first position, the base of the body can be spaced away from the air outlet. In this position, air is allowed to flow out of the air outlet. In the second position, the body can close the air outlet, preventing air from flowing out. For example, the base of the body can close the air outlet, preventing air from flowing out. In the second position, the body can be flush with the air outlet.

[0030] In the first position, the base of the body can be positioned less than 0.5 cm, less than 1 cm, less than 2 cm, less than 3 cm, less than 4 cm, less than 5 cm, less than 6 cm, or less than 10 cm from the air outlet. Preferably, in automotive applications, the base of the body can be positioned less than 5 cm from the air outlet. More preferably, the base of the body can be positioned less than 2 cm from the air outlet.

[0031] The body can be placed in any intermediate position between the first and second positions. In some embodiments, these intermediate positions can be predetermined and occur at defined intervals between the first and second positions. This allows the body to be selectively positioned at specific, discrete points to regulate the airflow. Alternatively, in other embodiments, the body can be continuously moved across the entire range from the first to the second position. This enables precise and variable positioning of the body at any point within this range. This mechanism can provide better control of the airflow exiting the air outlet.

[0032] By moving the body between the first and second positions, the intensity of the airflow exiting the air outlet can be adjusted. Furthermore, by moving the body within this range, the position of the convergence point of the airflow exiting the air outlet can be controlled. The convergence point of the airflow can be the point at which the air converges after exiting the air outlet. In this way, moving the body between the first and second positions provides a flexible means of regulating the direction and intensity of the airflow.

[0033] In some embodiments, the body can be moved manually between the first and second positions, for example, by a user pushing it in or pulling it out. Alternatively, in other embodiments, the movement of the body between the first and second positions can be achieved via an externally driven mechanism, such as an electric one. In this embodiment, the body can be operatively connected to an actuator. The actuator can be configured to move the body linearly between the first and second positions. The actuator can be operated and controlled remotely, allowing precise adjustment of the body's position without direct manual interaction. In certain embodiments, the body's position can be adjusted automatically in response to one or more sensors detecting predetermined conditions.These predetermined conditions can include, for example, a change in temperature, detecting that the temperature is above or below a predetermined threshold, or a change in humidity that exceeds or falls below a predetermined threshold.

[0034] In the second position, the air outlet can be in an "off" position. In this position, the HVAC system connected to the air outlet can be switched off. In the first position, the air outlet can be in an "on" position. In this position, the HVAC system connected to the air outlet can be switched on. In all intermediate positions (i.e., all positions except the second position), the HVAC system can be switched on.

[0035] In some embodiments, the body may be restricted to moving exclusively along its longitudinal axis, while remaining stationary in all other directions relative to the air duct. For example, the body cannot be pivoted or tilted relative to the air duct.

[0036] By restricting the body to moving exclusively along its longitudinal axis and preventing it from pivoting or tilting, the design ensures that airflow disturbances near the air outlet are minimized. In this configuration, the elements responsible for controlling the airflow direction in the duct (the directional control elements) are positioned further away from the air outlet.

[0037] In some embodiments, the air duct outlet can be embedded in a panel or instrument panel. For example, the air duct outlet can be embedded in a cockpit panel. In this embodiment, the air outlet can be formed in the panel or instrument panel, and the air duct and air intake can extend behind the panel or instrument panel.

[0038] In one embodiment, the body can remain stationary with respect to the air duct, and at least one section of the body's fairing or instrument panel can be configured to move along its longitudinal axis with respect to the body. The fairing or instrument panel (or a section thereof) can be configured to move between a third position and a fourth position. In a third position, the base of the body can be spaced away from the air outlet (and consequently, the base of the body can be spaced away from the fairing or instrument panel), allowing air to flow out of the air outlet. In the fourth position, the body can close the air outlet. For example, in the fourth position, the base of the body can close the air outlet, preventing air from flowing out.In the fourth position, the base of the body can be flush with the air outlet (and consequently, the base of the body can be flush with the paneling or dashboard), and air is not allowed to escape from the air outlet.

[0039] The body can be asymmetrical about its longitudinal axis. One tip of the conical structure can be spaced away from the longitudinal axis in a direction perpendicular to the longitudinal axis.

[0040] This asymmetrical configuration can be particularly advantageous in scenarios where the air duct deviates from the longitudinal axis, for example, when the duct has a bend or curve near the air outlet. The offset tip of the conical structure can be designed to align with or follow the curvature of the air duct.

[0041] By ensuring that the shape and position of the tip of the conical structure correspond to the bend in the air duct, the design minimizes airflow disturbances as the air passes through the bent section and exits the air outlet. This reduction in turbulence is particularly important for maintaining a consistent and undisturbed airflow. The reduction in airflow turbulence achieved through this configuration can have the added benefit of reducing noise generated by the air outlet. Turbulence near the air outlet can lead to higher noise levels, which can be undesirable in environments where quiet operation is required.

[0042] In some embodiments, the body can be symmetrical about the longitudinal axis. For example, the body can include a conical structure, and the apex of the conical structure can be aligned with the longitudinal axis. The conical structure can have a consistent and uniform taper from the base to the apex, thus ensuring a uniform surface area distribution around the axis.

[0043] This symmetrical design can be particularly advantageous when the air duct extends essentially along its longitudinal axis. In such configurations, the symmetrical conical body ensures that the airflow is distributed evenly around the body as it moves through the air duct, thereby minimizing turbulence and pressure imbalances.

[0044] A cross-sectional area of ​​the passage in a plane perpendicular to the longitudinal axis can comprise a circular ring or an elliptical circular ring.

[0045] An axis perpendicular to the longitudinal axis can include a transverse axis. An axis orthogonal to both the longitudinal and transverse axes can include a vertical axis. The transverse axis and the vertical axis can define a transverse plane. The cross-sectional area of ​​the passage can be defined within the transverse plane.

[0046] The shape of the passage allows for an even distribution of air across the entire circumference of the body as it flows through the passage, which is advantageous for air distribution control. This configuration is particularly useful in vehicle systems where air can be directed more effectively to specific occupant areas or points of contact (e.g., head or torso) with minimal turbulence.

[0047] The air outlet can comprise a substantially circular opening. The air outlet can comprise a substantially elliptical opening. In some embodiments, the air outlet can comprise a circular opening if the body has a substantially circular base. In some embodiments, the air outlet can comprise an elliptical opening if the body has a substantially elliptical base. In this way, the shape of the air outlet can be configured to match the shape of the body's base. This ensures that the air outlet can be completely closed when the body's base is flush with the air outlet.

[0048] The cross-sectional area of ​​the passage can remain essentially constant over the entire length of the body if the body is in the first position or if the paneling or dashboard is in the third position.

[0049] A cross-sectional area of ​​the passage that remains essentially constant along the entire length of the body offers several advantages from a fluid dynamics perspective. This configuration promotes a uniform, laminar airflow through the passage, thereby minimizing pressure drops and turbulence that could otherwise occur with varying passage cross-sections. Furthermore, this design helps maintain a consistent velocity profile along the length of the duct, which is important for reducing flow separation and minimizing energy losses.

[0050] The body and the air duct can be shaped and positioned relative to each other in such a way that, during use, air exiting the air outlet converges at a point spaced away from the air outlet.

[0051] By guiding the airflow to converge at a specific point, the air outlet can precisely direct cooled or heated air to target areas, such as contact points on the occupant, thereby improving occupant comfort. The air outlet also contributes to a quieter passenger compartment by maintaining a streamlined airflow.

[0052] The body can be hollow. Alternatively, it can be solid. A hollow body can reduce mass and the amount of material required for manufacturing. Conversely, a solid structure can provide additional strength and stability, especially in applications where structural integrity is critical. Both configurations can be designed to prevent airflow through the body itself, ensuring that air is channeled around the body as it flows through the air duct and out of the air outlet.

[0053] The at least one directional control element can be positioned closer to the air inlet than to the body. The at least one directional control element can be positioned closer to the air inlet than to the air outlet. The at least one directional control element can be positioned within 30 cm, 25 cm, 20 cm, 15 cm, 10 cm, or 5 cm of the air inlet. Preferably, the at least one directional control element can be positioned within 15 cm of the air inlet. Positioning the at least one directional control element closer to the air inlet than to the body or air outlet helps to reduce noise to which users are exposed near the air outlet. By controlling the airflow direction earlier in the air duct, turbulence and mechanical noise near the outlet are minimized.

[0054] The at least one directional control element can include at least one actuator operatively connected to the at least one nozzle. The at least one actuator can be configured to move the at least one nozzle in such a way as to change the direction of air flowing from the air inlet to the body.

[0055] The nozzle can be rotatably mounted in the air duct. The nozzle can have a partial spherical shape. More specifically, the nozzle can comprise a solid spherical segment with a through-passage. The through-passage can have a truncated cone shape. A first opening of the through-passage can comprise a nozzle air inlet, and a second opening of the through-passage can comprise a nozzle air outlet. In an alternative embodiment, the nozzle can be in the form of a hollow spherical segment. The nozzle can comprise a hollow spherical shell with two diametrically opposed circular recesses. The first circular recess can comprise the nozzle air inlet, and the second, opposing recess can comprise the nozzle air outlet. A nozzle passage can be formed between the nozzle air inlet and the nozzle air outlet.

[0056] The nozzle's orifice can be configured to allow airflow through it. Air can be configured to enter the nozzle through the air inlet, flow through the orifice, and exit through the air outlet. The nozzle's semi-spherical shape ensures a streamlined and efficient airflow.

[0057] A section of the air duct accommodating the nozzle can have a geometry complementary to the nozzle itself. Specifically, the inner contour of this section of the air duct can be designed to match the outer profile of the nozzle. More precisely, the inner surface of the air duct section housing the nozzle can essentially resemble the inner surface of a second spherical segment, the second spherical segment being geometrically similar to the spherical segment forming the nozzle. The matching curvature of the air duct and nozzle sections ensures a tight and secure fit between the two components. The nozzle is fixed within this section of the air duct, and the alignment of its curvatures allows the nozzle to rotate freely within this section of the air duct.

[0058] The nozzle can be configured to deflect the airflow passing through the air duct. The shape and orientation of the nozzle can be used to redirect the airflow.

[0059] The at least one actuator can comprise a first actuator configured to rotate the nozzle about at least one first axis. The at least one actuator can comprise a second actuator configured to rotate the nozzle about at least one second axis, the second axis being perpendicular to the first axis.

[0060] This dual-actuator configuration allows independent control along two different axes and offers a comprehensive range of directional settings for optimal adjustment of the airflow direction. Alternatively, the system can integrate alternative actuation mechanisms, such as a single actuator capable of simultaneous adjustment along both axes, or a more complex system with multiple actuators.

[0061] The first actuator can be a rotary actuator. The second actuator can also be a rotary actuator. The rotary actuator can be an electric motor.

[0062] The first actuator can be connected to the nozzle via a rack and pinion mechanism. In this configuration, the rack component can be integrated into the nozzle. In particular, the rack can be located on the outer surface of the nozzle. The pinion can be in the form of a gear. The gear can be coupled to the rotary actuator. When the rotary actuator is actuated, the gear can be driven to move along the rack, resulting in the rotation of the nozzle around its first axis. This mechanical connection effectively converts the rotation of the gear into the desired angular displacement of the nozzle, thus enabling precise control of its orientation.

[0063] The second actuator can be mechanically connected to the nozzle. The second actuator can be a rotary actuator. In one example, the second actuator can be operatively connected to an annular structure that surrounds and supports the nozzle. The annular structure can be connected to the nozzle in such a way that it is allowed to pivot about the first and second axes. When activated, the second actuator drives the rotation of the ring and the nozzle about the second axis, thus enabling precise angular adjustments of the nozzle along this axis.

[0064] The person skilled in the art understands that any suitable mechanism can be used to rotate the nozzle about at least two vertical axes.

[0065] The air duct outlet may also include an electronic control unit. The electronic control unit may be connected to at least one actuator. The electronic control unit may be programmed to adjust the nozzle position based on user input. The electronic control unit may be connected to an actuator configured to control the body's movement along its longitudinal axis. The electronic control unit may be programmed to adjust the body's position based on user input. The electronic control unit may be connected to or part of a vehicle computer.

[0066] The electronic control unit can be connected to one or more sensors. These sensors can be located within a vehicle.

[0067] The electronic control unit can be programmed to automatically adjust the position of at least one nozzle or the position of the body based on data received from one or more sensors.

[0068] The electronic control unit can also be configured to control the temperature of the air flowing through the air duct. For example, the electronic control unit can be linked to the vehicle's HVAC system to regulate the temperature of the air passing through the air duct outlet. The electronic control unit can adjust the heating or cooling output of the HVAC system.

[0069] The electronic control unit can be programmed to automatically adjust the temperature based on data received from one or more sensors.

[0070] These sensors can include, but are not limited to, temperature sensors, humidity sensors, occupancy sensors, motion sensors, one or more microphones, and / or proximity sensors. Temperature and humidity sensors can be configured to monitor the internal climate of the vehicle's passenger compartment and detect changes in environmental conditions.

[0071] Occupancy sensors can be configured to detect the presence and position of passengers inside a vehicle. The data from these sensors can be used by the electronic control unit to direct airflow to occupied areas, thus ensuring occupant comfort. Motion or proximity sensors can be configured to detect user gestures. These gestures may include user input. The electronic control unit can process data from these sensors to automatically adjust the position of the body or one or more air vents.

[0072] The electronic control unit can also be configured to use one or more microphones to detect user input in real time. Microphones located in the vehicle passenger compartment can be configured to capture audio input, such as voice commands. These microphones can be integrated with speech recognition software, allowing the user to issue verbal commands to adjust air duct control settings, including airflow direction, intensity, and / or temperature.

[0073] The electronic control unit can be configured to communicate with a user interface. The user interface can be integrated into a vehicle. The user interface can be integrated into the vehicle's dashboard. Additionally or alternatively, the user interface can be implemented in a user device. The user device can be any suitable computing device, such as a phone, tablet, computer, laptop, or wearable device (e.g., a smartwatch). The user interface can include a touchscreen. The user interface can be configured to receive user input from the user. For example, the user interface can be configured to receive user input via the touchscreen.

[0074] The body may include a display interface. The display interface may be part of the user interface. The display interface may communicate with the electronic control unit. The display interface may be configured to communicate wirelessly with the electronic control unit. The display interface may be connected to the electronic control unit (e.g., using a wired connection). The display interface may be capable of receiving user input. The user input may include a request to change the direction of the airflow exiting the air outlet. The user input may include a request to change the temperature of the airflow exiting the air outlet. The display interface may be configured to forward the user input to the electronic control unit.The electronic control unit, on the other hand, can be configured to control the position of the body, the position of at least one nozzle and / or the temperature of the airflow in such a way as to implement the user input.

[0075] The display interface can be positioned at the base of the body. More specifically, the display interface can be positioned at the base of the conical structure. The base of the body can be configured to face the user during use.

[0076] The display interface may include a touchscreen. The display interface may be configured to receive user input via the touchscreen. The display interface may be configured to show information regarding the temperature, direction, and / or intensity of the airflow exiting the air duct outlet.

[0077] The display interface, positioned at the base of the unit, offers several technical advantages in terms of user interaction and functionality. By being placed at the base of the unit, facing the user during operation, the display interface provides immediate and intuitive access for adjusting airflow parameters.

[0078] Furthermore, integrating the display interface into the base of the air vent minimizes the control unit's footprint on the dashboard, resulting in improved space efficiency within the vehicle interior. Additionally, placing the display on the vent body simplifies the mechanical and electronic design by combining the control and airflow systems into a single, unified component.

[0079] The user interface can include a second display interface. This second display interface can be implemented in the form of a ring surrounding the air outlet. The second display interface can also include a touchscreen.

[0080] The second display interface can be configured to receive user input via the touchscreen. The second display interface can be configured to show information regarding the temperature, direction, and / or intensity of the airflow exiting the air duct outlet.

[0081] The second display interface can include one or more light sources. These light sources can be configured to illuminate the second display. They can include one or more LEDs. For example, the light sources can be configured to illuminate the second display interface with different colors. The second display interface can be configured to use different colors to visually indicate the temperature of the airflow exiting the air duct outlet. For instance, blue can represent cooler air, indicating that the system is operating in cooling mode, while red can indicate warmer or heated air. This color-based system provides an intuitive visual representation of the airflow temperature, allowing the user to quickly assess and adjust the climate control settings.

[0086] In the drawings, corresponding elements are provided with corresponding reference numerals. It is understood that the use of terms such as vertical, horizontal, left, right, top, bottom, clockwise, counterclockwise, etc., serves only descriptive purposes to facilitate understanding and thus does not preclude alternative orientations or configurations of the disclosed invention.

[0087] Fig. Figure 1 shows a schematic diagram of a ventilation system 100. The ventilation system 100 comprises an air duct outlet 120, a vehicle HVAC system 160, and a vehicle computer 104. The ventilation system 100 may also include a sensor system 102 and an external user interface 122.

[0088] The sensor system 102 comprises a humidity sensor 124, a heat sensor 128, and a camera 126. The heat sensor 128 may include an infrared (IR) sensor. The sensor system 102 may include one or more of the aforementioned sensors 124, 128, and 126. The sensor system 102 can be used to detect the temperature, humidity, presence of one or more occupants, and position of one or more occupants within a vehicle passenger compartment. Although not explicitly shown, other sensors may be integrated into the sensor system 102. For example, the sensor system 102 may include one or more of the following: touch or proximity sensors, a microphone, passenger compartment pressure sensors, and / or CO2 sensors. In some embodiments, the one or more sensors 102 may be used by a user to provide instructions or feedback to the vehicle computer 104.For example, one or more sensors 102 can be used by a user to instruct the vehicle computer 104 to control the operation of the air guide outlet 120.

[0089] The external user interface 122 can include a mobile phone 130 and / or a portable computer 132. Although for the sake of simplicity in Fig. 1 Since only the specific examples of the mobile phone 130 and the portable computer 132 are presented, it is obvious to the person skilled in the art that the external user interface 122 can comprise any suitable type of computing device, such as a smartphone, a tablet computer, a laptop computer, a desktop computer or a wearable device (e.g. a smartwatch).

[0090] The HVAC system can be configured to control the intensity and / or temperature of the airflow entering the air duct outlet 120. The vehicle's HVAC system can be connected to an air inlet of the air duct outlet 120. The HVAC system communicates with the vehicle computer 104, and the vehicle computer 104 is configured to control the operation of the HVAC system 160.

[0091] The vehicle computer 104 comprises a memory 106, a processor 114, and a communication system 116. The vehicle computer 104 may include a user interface 118. The vehicle computer 104 may also include other components (not shown for simplicity) that are typically found in general-purpose computers.

[0092] Memory 106 can contain an operating system (OS) 110, an electronic control unit (ECU) 108, and a database 112. The operating system (OS) 110 serves as the core software that manages and controls the hardware and software resources of the computer 104. The operating system enables various tasks, such as process management, memory allocation, file system operations, and device management. The electronic control unit (ECU) 108 is configured to control the operation of the air duct outlet 120, as described in more detail below. The database 112 can contain any other data stored in the memory 106 of the vehicle computer 104.

[0093] Memory 106 stores information that processor 114 can access, including instructions and data that can be executed by processor 114 or otherwise used. Memory 106 includes processor-executable instructions which, when executed by processor 114, cause the vehicle computer 104 to control the air duct 120.

[0094] The memory 106 can be of any type capable of storing information accessible to the processor 114, including a computer-readable medium or any other medium that stores data readable by an electronic device, such as a hard disk, memory card, ROM, RAM, DVD, or other optical discs, as well as other writable and read-only storage media. Systems and methods can include different combinations of the foregoing, with different portions of the instructions and data stored on different types of media.

[0095] The processor 114 can be any conventional processor, such as a microprocessor or a microcontroller. Alternatively, the processor 114 can be a purpose-built device, such as an ASIC. Although the processor 114, the memory 106, and the communication system 116 are arranged according to the representation in Fig. Since the processor and memory are functionally located within the same block, it is obvious to a person skilled in the art that the processor and memory may in fact comprise multiple processors and memories, which may or may not be housed within the same physical enclosure. For example, instead of being housed in the same computer, the processor 114 and the memory 106 may be housed in separate devices. Although references made herein to a processor or memory are assumed to be mounted on a vehicle, it is understood that such references include references to a collection of processors or computers or memories, which may or may not operate in parallel and may or may not be positioned or mounted in a vehicle.

[0096] The communication system 116 can include one or more wireless transmitters and receivers that communicate with the sensor system 102, the external user interface 122, the vehicle HVAC system 160, and / or the air duct 120 via various types of networks. Additionally or alternatively, the communication system 116 can be configured to control data exchange via a wired connection between any of the aforementioned components.

[0097] The user interface 118 can include a GUI. The user interface 118 can include a touchscreen integrated into a vehicle's dashboard. This touchscreen can be positioned near the air duct outlet 120. In an example (in Fig. (As shown in Figure 3b), the touchscreen comprises a ring surrounding an air outlet of the air duct 120. This user interface 118 can serve as a control hub, providing an intuitive platform for users to interact with and optionally control the air duct 120. Users can easily navigate and input commands to control the air duct 120 via the GUI.

[0098] For example, a user can enter instructions into the user interface 118 to request that the direction of the airflow from the air outlet 120 be changed. These instructions can be forwarded to the electronic control unit 108. The electronic control unit 108 can be configured to subsequently send one or more instructions to the air outlet 120. These instructions can be configured to cause the air outlet 120 to change the direction of the airflow exiting it. Additionally or alternatively, the user can enter instructions into the user interface 118 to request that the temperature and / or intensity of the airflow from the air outlet 120 be adjusted. These instructions can also be forwarded to the electronic control unit 108.The electronic control unit 108 can be configured to subsequently send one or more instructions to the air outlet 120 and / or the HVAC system 160. These instructions can be configured to cause the air outlet 120 and / or the HVAC system 160 to change the intensity and / or temperature of the airflow exiting the air outlet 120.

[0099] It is understood that in further embodiments, the user can control the operation of the air duct 120 and / or the HVAC system 160 using the external user interface 122. For example, the user may be able to control the direction, intensity, and / or temperature of the airflow from the air duct 120 using the mobile phone 130 and / or the portable computer 132. In this embodiment, the external user interface 122 may be configured to send one or more signals to the electronic control unit 108. The one or more signals may include instructions configured to adjust the direction, intensity, and / or temperature of the airflow.The electronic control unit 108 can be configured to send one or more instructions to the air outlet 120 and / or the HVAC system 160 upon receiving one or more signals from the external user interface 122. The one or more instructions can be configured to cause the air outlet and / or the HVAC system 160 to change the direction of the airflow (as described with reference to the continuous figures).

[0100] In yet another embodiment, the operation of the air outlet 120 and / or the HVAC system 160 can be automatically controlled based on an output from the sensor system 102. The vehicle computer 104 can be configured to receive data from the sensor system 102 and control the operation of the air outlet 120 in response to the data received from the sensor system 102. More specifically, the data collected by the sensor system 102 can be used to enable automated adjustment of the airflow, air temperature, and / or airflow intensity from the air outlet 120 based on occupant presence or position, temperature, and / or humidity. The electronic control unit 108 can be programmed to automatically adjust the direction, temperature, and / or intensity of the airflow based on the detection of a specific environmental condition.For example, the electronic control unit 108 can be configured to adjust the direction of the airflow based on: the temperature exceeding a predefined threshold, the humidity exceeding a predefined threshold, and / or a user being detected at a specific location within the vehicle, etc.

[0101] In some embodiments, the sensor system 102 can be configured to receive user input. For example, the user can use gestures or audible commands that are detected by the sensor system 102 (e.g., using a microphone, camera, or other sensors). The sensor system 102 can then be configured to send the user input to the vehicle computer 104 for interpretation. After receiving and interpreting the user input, the vehicle computer 104 can be configured to send instructions to the air duct 120 and / or the HVAC system 160 to adjust the direction, intensity, and / or temperature of the airflow exiting the air duct 120.

[0102] In this embodiment, the air guide outlet 120 comprises a display interface 130 and one or more outlet actuators 132.

[0103] The display interface 130 is part of (or connected to) the air duct outlet 120, as described with reference to the continuing figures. The display interface 130 communicates with the electronic control unit 108. The display interface 130 is capable of receiving user input. For example, the display interface 130 may include a touchscreen that the user can use to provide user input. The display interface 130 may be configured to display information regarding the direction, intensity, and / or temperature of the airflow exiting the air duct outlet 120.

[0104] The display interface 130 is configured to forward user input to the electronic control unit 108. The electronic control unit 108, in turn, is configured to control the direction, intensity, and / or temperature of the airflow exiting the air outlet 120 (e.g., by sending appropriate instructions to the HVAC system 160 and / or the air outlet 120).

[0105] The one or more outlet actuators 132 are configured to control the position and / or orientation of one or more elements in the air guide outlet 120 in order to adjust the direction or intensity of the airflow exiting the air guide outlet 120. The operation of the one or more outlet actuators 132 is described in more detail with reference to the following figures.

[0106] The structure of the air guide outlet 120 is now described with reference to Fig. 2a and Fig. 2b is described in more detail.

[0107] Fig. Figure 2a shows a cross-sectional view of the air guide outlet 120 in a central position. Fig. Figure 2a shows three axes 230. The axes 230 comprise a longitudinal axis X, a transverse axis Z and a vertical axis Y. Fig. Figure 2b shows a rear view (viewed from the direction of an arrow representing an air inlet 208) of the air guide outlet 120 in the Fig. 2a shown middle position.

[0108] The air duct outlet 120 comprises an air duct 200, which has an air inlet 208 and an air outlet 226. The air inlet 208 is connected to the vehicle HVAC system 160. The air outlet 226 comprises a circular opening at one end of the air duct 200.

[0109] The air duct outlet 120 further comprises a conical body 214, which is positioned in the air duct 200 between the air inlet 208 and the air outlet 226. The conical body 214 is configured to prevent airflow through it, while allowing airflow through a passage 219 defined between an inner surface 217 of the air duct 200 and an outer surface 215 of the conical body 214. The passage 219 extends substantially around the entire circumference of the conical body 214. The air duct outlet 120 further comprises a directional control element in the form of a nozzle 220. The nozzle 220 is positioned between the air inlet 208 and the conical body 214. The nozzle 220 is not connected to the conical body 214 and is spaced apart from it.The nozzle 220 can be operated to change the direction of the airflow flowing from the air inlet 208 to the conical body 214, thereby controlling the direction of the airflow from the air outlet 226. The operation of the nozzle 220 is described with reference to... Fig. Sections 6a to 9a are described in more detail.

[0110] In this embodiment, the air duct 200 extends substantially along the longitudinal axis X (i.e., the air duct 200 is substantially parallel to the longitudinal axis X). However, in this embodiment, the air duct 200 does not have a uniform cross-section along the longitudinal axis X in the ZY plane. In other words, the cross-sectional area in the ZY plane of the air duct 200 varies along its length.

[0111] The air duct 200 can be divided into three sections: a first section 202, a second section 204, and a third section 206. The first section 202 comprises an essentially tubular structure. The walls of the first section extend parallel to the longitudinal axis X. The second section 204 comprises a hollow spherical segment. A curvature of an inner surface 205 of the second section 204 is configured to geometrically resemble a curvature of an outer surface of the nozzle 220. The nozzle 220 is positioned within the second section 204. In this way, the matching curvature of the second section 204 of the air duct 200 and the nozzle 220 ensures a tight and secure fit between the two components. The alignment of their curvatures allows the nozzle 204 to rotate freely within this section of the air duct 200.The third section 206 of the air duct 200 comprises a tapered structure. Specifically, the cross-sectional area of ​​the third section 206 initially increases in the ZY plane until it reaches a maximum at point 201. Subsequently, the cross-sectional area of ​​the third section 206 narrows in the ZY plane to a minimum at point 231. Finally, the cross-sectional area of ​​the third section 206 increases in the ZY plane towards the air outlet 226. The conical body 214 is positioned within the third section 206. One end of the first section 202 is connected to the first end of the second section 204. Conversely, the second end of the second section 204 is connected to the first end of the third section 206. The third section terminates at the air outlet 226.

[0112] It is clear to the expert that the air duct 200 can have any suitable, essentially tubular shape. An example of an alternative air duct is given with reference to Fig. 5a and Fig. 5b discussed.

[0113] The nozzle comprises a solid spherical segment with a through-passage 212. The through-passage has a truncated cone shape. A first opening of the through-passage 212 comprises a nozzle air inlet, and a second (diametrically opposite) opening of the through-passage 212 comprises a nozzle air outlet. The first opening is positioned closer to the air inlet 208 than the second opening. The first opening is wider than the second opening. The nozzle through-passage 212 is formed between the nozzle air inlet and the nozzle air outlet.

[0114] The orifice 212 of the nozzle 220 is configured to allow an airflow through it. Air is configured to enter the nozzle 220 through the air inlet, flow through the orifice 212, and exit through the air outlet. The nozzle 220 is configured to deflect the airflow flowing through the air duct 200. The nozzle is configured to redirect the airflow depending on its orientation.

[0115] The air guide outlet 100 further comprises one or more outlet actuators 132. In this embodiment, the air guide outlet 100 comprises a first actuator 132a and a second actuator 132b. The first actuator 132a and the second actuator 132b comprise rotary actuators. In this embodiment, the rotary actuators 132a and 132b each comprise an electric motor.

[0116] The nozzle 220 is operatively connected to both the first actuator 132a and the second actuator 132b. The first actuator 132a is configured to rotate the nozzle 220 relative to the air line 200. Specifically, the first actuator 132a is configured to rotate the nozzle 220 about the vertical Y-axis. The second actuator 132b is also configured to rotate the nozzle 220 relative to the air line 200. More specifically, the second actuator 132b is configured to rotate the nozzle 220 about the transverse Z-axis. A virtual pivot point of the nozzle 220 is shown as point 216.

[0117] The first actuator 132a is connected via a mechanism consisting of a rack 222 and pinion (best in Fig. (2b) is connected to the nozzle 220. In this configuration, the rack 222 is integrated into the nozzle 220. Specifically, the rack 222 is located on the outer surface of the nozzle 220. The pinion is in the form of a gear 218. The gear 218 is coupled to the first actuator 132a. When the first actuator 132a is actuated, the gear 218 is driven to move along the rack 222, resulting in the rotation of the nozzle 220 about the Y-axis. This mechanical connection effectively converts the rotation of the gear 218 into the desired angular displacement of the nozzle 220, thus enabling precise control of its orientation.

[0118] The second actuator 132b is connected to the nozzle 220 via a mechanical linkage. This linkage comprises a pin 298 and an annular structure 299. The annular structure 299 surrounds and supports the nozzle 220. The second actuator 132b is connected to the annular structure 299 via the pin 298. During operation, the second actuator 132b drives the rotation of the pin 298, thus rotating the annular structure 299 and the nozzle 220 about the second axis (i.e., the Z-axis). This enables precise angular displacements of the nozzle 220 along the second axis.

[0119] This dual actuator configuration allows independent control via two different axes (Z-axis and Y-axis) and offers a comprehensive range of directional settings for optimal adjustment of the direction of the airflow impinging on the conical body 214. By changing the orientation of the nozzle 220, the direction of air exiting the air outlet 226 can be changed. The operation of the first actuator 132a and the second actuator 132b is described with reference to Fig. Sections 6a to 9b are described in more detail.

[0120] In this embodiment, the conical body 214 comprises a flat circular base 211 that tapers to a tip 225. In this embodiment, the taper is uneven. The conical body 214 is symmetrical about the longitudinal X-axis. The conical body 214 has a tapered cross-section in the direction of the air inlet 208. Therefore, the flat base is positioned closer to the air outlet 226 than to the air inlet. Likewise, the tip 225 is positioned closer to the air inlet 208 than to the air outlet 226. In this embodiment, the tip 225 is rounded. The conical body 214 is hollow.

[0121] The conical body 214 is made of an airtight material. For example, the conical body 214 can be made of plastic or metal. The conical body 214 comprises a continuous outer surface that prevents airflow through the body 214. In this way, the structure of the body 214 prevents air from flowing through its interior (as in Fig. (as shown in Figures 6a, 7a and 10a-10c). Rather, the airflow is directed around the body 214 through the passage 219 defined between the outer surface 215 of the body 214 and the inner surface 217 of the air duct 200.

[0122] During operation, the airflow is generated by the vehicle's HVAC system 106 and directed through the air inlet 208 into the air duct 200. The air initially flows through the first section 202 of the air duct, following a substantially linear path. The airflow then enters the nozzle opening 212, where it can be deflected by the nozzle 220 depending on its position. Upon exiting the nozzle opening, the airflow reaches the third section 206, where it impacts the conical body 214.

[0123] The airflow is then redirected around the outer surface of the conical body 214, flowing through the passage 219 formed between the body and the inner surface of the air duct. The conical body 214 is configured to define an annular opening in the third region 206 of the air duct at a point 231 where the cross-section of the duct 200 decreases in diameter, in order to generate an annular airflow that converges at a point on the X-longitudinal axis spaced from the air outlet 226 (best in Fig. 3a, Fig. 4a and Fig. 10a). In the area of ​​the conical body 214, the cross-section of the air duct 200 varies such that the cross-section of the passage 219 is essentially constant (when the conical body 214 is in the Fig. 2a is the position shown).

[0124] The nozzle 220 influences the angle at which the mass of the airflow is distributed around the conical body 214, which in turn influences the direction of the airflow beyond the point of convergence.

[0125] Advantageously, the conical structure of the body 214 offers an aerodynamic advantage in the air duct 200. By tapering from a wider base 211 to a narrower tip 225, the conical shape allows the airflow to be redirected around the body 214 without obstruction, thereby reducing turbulence in the air flowing through the duct 200.

[0126] The cross-sectional area of ​​the passage 219, which remains essentially constant over the entire length of the body 214 (when the body is in the Fig. The configuration shown in Figure 2a (position shown) offers clear advantages from a fluid dynamics perspective. This configuration results in an essentially constant airflow velocity around the conical body 214. By maintaining a consistent flow profile around the conical body 214, air turbulence and pressure fluctuations are minimized in this design. This, in turn, reduces noise levels typically generated by a disturbed airflow, leading to quieter operation of the diffuser 120.

[0127] The air guide outlet 120 can further include a third actuator (not shown for simplicity). The third actuator can be configured to move the conical body 214 linearly along the X-axis. The linear movement of the conical body 214 is schematically represented by an arrow 224. The third actuator can be a rotary actuator or a linear actuator. Like the first actuator 132a and the second actuator 132b, the operation of the third actuator can be controlled by the electronic control unit 108.

[0128] The conical body 214 is positioned between a first position (in Fig. 2a) and a second position (not shown). In the first position, the base 211 of the conical body 214 is spaced away from the air outlet 226. In this position, air is allowed to flow out of the air outlet 226. In the second position, the base 211 of the conical body 214 is flush with the air outlet 226. In this position, an outer edge of the flat base 211 rests against an inner surface 217 of the air duct 200 at the minimum point 231. In the second position, air is not allowed to flow out of the air outlet 226, as the passage 219 through the conical body 214 is closed.

[0129] In some embodiments (not shown), the air duct outlet 120 may include a sensor configured to detect when the conical body 214 is positioned in the second position. Upon detection that the conical body 214 has reached the second position, the sensor may send signals to the electronic control unit 108. The electronic control unit 108 may be programmed to send control instructions to the HVAC system 160 in response, with the instructions configured to disable or turn off the HVAC system.

[0130] Integrating a sensor to detect when the conical body 214 is in the second position provides a simple and intuitive method for automatically switching off the HVAC system. Furthermore, this automated approach prevents unnecessary energy consumption due to the potential operation of the HVAC system when air cannot escape from the air outlet 226.

[0131] The conical body 214 is configured to move exclusively along its longitudinal X-axis. This prevents the conical body 214 from tilting or rotating within the air duct 200. By restricting the body 214 to moving only along its longitudinal X-axis and preventing it from pivoting or tilting, the design ensures that airflow disturbances near the air outlet 226 are minimized. In this configuration, the nozzle 220, responsible for controlling the airflow direction in the air duct 200, is positioned further away from the air outlet 226. This reduces noise levels experienced by users near the air outlet 226.

[0132] The conical body 214 can be placed in any intermediate position between the first position (in Fig. 2a) and the second position. In some embodiments, these intermediate positions can be predetermined and occur at defined intervals between the first and second positions. This allows the body to be selectively positioned at specific, discrete points to regulate the airflow.

[0133] By adjusting the position of the conical body 214, the velocity of the airflow can be modulated due to the change in the passage 219 between the conical body 214 and the air duct 200. When the conical body moves closer to the first position (in Fig. In the first position (as shown in Figure 2a), the passage 219 is wider, allowing for a lower air velocity. When the conical body 214 moves to the second position, the passage 219 narrows, increasing the airflow velocity. To ensure that this adjustment does not result in less intuitive operation for the occupant, the movement of the conical body 214 can be electronically linked to the mass flow rate provided by the HVAC unit. Specifically, in the second position, where the passage 219 is narrower, the HVAC unit can reduce the overall mass flow rate, and in the first position, where the passage 219 is wider, the HVAC unit can increase the mass flow rate.

[0134] Furthermore, the convergence point of the airflow exiting the air outlet 226 can be influenced by moving the conical body 214. When the conical body 214 changes its position, it alters the angle and flow profile of the surrounding airflows. If the conical body 214 is positioned closer to the air outlet 226, the airflows are deflected more sharply, resulting in a closer convergence point. Conversely, the airflow converges further away from the outlet when the conical body 214 is located further away from the outlet.

[0135] In certain embodiments, the position of the conical body 214 can be automatically adjusted in response to one or more sensors 102 detecting predetermined conditions. These predetermined conditions may include, for example, a change in temperature, detection that the temperature is above or below a predetermined threshold, or a change in humidity that exceeds or falls below a predetermined threshold, etc.

[0136] It is obvious to the person skilled in the art that in some embodiments the conical body 214 can be moved manually between the first position and the second position, for example by being pushed in or pulled out by a user.

[0137] The conical body 214 and the air duct 200 can have a number of different shapes depending on system requirements. Some exemplary conical bodies and air ducts are now described with reference to Fig. 3a to 5b described

[0138] It will now be on Fig. Reference is made to 3a. Fig. Figure 3a shows a cross-sectional view of a first example 300 for an air guide outlet comprising a first conical body 352.

[0139] The first conical body 352 is positioned in a first air duct 330. In Fig. 3a The first conical body 352 is in a first position relative to the first air duct 330. In the first position, the first conical body 352 is spaced away from the air outlet, allowing air to flow out of the air outlet. In some embodiments, the first conical body 352 can be movable along the X longitudinal axis from the first position to a second position. In the second position, the first conical body 352 is configured to close the air outlet, preventing air from flowing out of the air outlet.

[0140] The first conical body 352 comprises an essentially flat circular base 308. The first conical body 352 has a gradually curved contour. The contour of the first conical body 352 begins at the base 308 and tapers uniformly to a pointed tip 316. The contour of the first conical body 352 can be divided into two regions. In a first region 350, the cross-sectional area of ​​the first conical body 352 (out of the ZY plane) gradually increases until it reaches a maximum point. The cross-section then begins to gradually decrease, forming a convex profile. In a second region 306 (which continues uniformly from the first region 350), the cross-sectional area of ​​the first conical body 352 (out of the ZY plane) tapers uniformly and essentially linearly to the tip 316.In contrast to the conical body 219, the first conical body 352 has a pointed tip instead of a rounded one. The first conical body 352 is symmetrical about the X longitudinal axis.

[0141] The first conical body 352, like the conical body 219, is airtight. Thus, air is configured to flow around the first conical body 352 in a first passage 319, defined between an outer surface of the first conical body 352 and an inner surface of the first air duct 330. The direction of the airflow around the first conical body 352 is shown by arrows 304 and 306.

[0142] The first conical body 352 is configured to define an annular opening in the air duct 330 at a point where the cross-sectional area of ​​the air duct 330 decreases in diameter, in order to generate an annular airflow that converges at a convergence point 302 on the X-longitudinal axis at a point spaced from the air outlet 226. In the region of the first conical body 352, the cross-sectional area of ​​the air duct 330 varies such that the cross-sectional area of ​​the passage 319 is essentially constant (when the conical body 352 is in the Fig. 3a is the position shown).

[0143] With reference to the following Fig. 3b shows a front view of the in Fig. 3a shows the first example 300 for the air guide outlet, which includes the first conical body 352.

[0144] In this view, the essentially flat base 308 of the first conical body 352 is more clearly visible. The flat base 308 of the first conical body 352 is configured to be visible to a user when the air guide outlet 300 is in use. The air guide outlet 300 is embedded in a dashboard 210.

[0145] The base 308 of the first conical body 352 includes the display interface 132. As mentioned previously, the display interface 132 communicates with the electronic control unit 108 (either wirelessly or via a wired connection). In this embodiment, the display interface 132 includes a touchscreen arranged on a surface of the base 308 of the first conical body 352. One or more electrical components (not shown) of the display interface 132 are located in a cavity 317 (preferably in Fig. 3a) of the first conical body 352 is housed.

[0146] The display interface 132 is capable of receiving user input via the touchscreen. The user input can include a request to change the direction of the airflow exiting the air outlet 226. The user input can also include a request to change the temperature of the airflow exiting the air outlet 226. The display interface 132 is configured to forward the user input to the electronic control unit 108. The electronic control unit 108, in turn, is configured to control the position of the conical body 214, 352, the position of the nozzle 220, and / or the temperature of the airflow so that the user input is implemented. The electronic control unit 108 can be configured to control the position of the conical body 214, 352, and the position of the nozzle 220 by sending one or more instructions to the outlet actuators 132 (e.g.,to control the first actuator 132a, the second actuator 132b and / or the third actuator (not shown).

[0147] In some embodiments, the display interface 130 can be configured to display information regarding the temperature, direction and / or intensity of the airflow exiting the air guide outlet 300.

[0148] The display interface 130, positioned at the base 308 of the first conical body 352, offers several technical advantages in terms of user interaction and functionality. By being placed at the base 308, which faces the user during operation, the display interface provides immediate and intuitive access for adjusting airflow parameters. This intuitive design is based on the fact that the display 130 is integrated directly into the air outlet that the user wishes to adjust, rather than relying on a separate, remotely positioned screen.

[0149] This placement of the 130 display also creates an immediate feedback loop for the user. When the user adjusts the airflow parameters via the 130 display interface, their hand is already in front of the air outlet, allowing them to directly feel changes in temperature, airflow speed, or direction. This tactile and visual feedback ensures a seamless and efficient adjustment process, thus improving the overall user experience.

[0150] In contrast, remotely controlled electronic diffusers operated via a separate screen lack this immediate feedback mechanism, so the user must rely solely on visual cues from the remote interface.

[0151] The air guide outlet 300 also includes a second display interface 310, designed as a ring surrounding the air outlet 226 on the instrument panel 210. The second display interface 310 contains a touchscreen that allows the user to provide input. In this embodiment, the touchscreen has a "plus" symbol 312 and a "minus" symbol 314, which users can press to increase or decrease the temperature of the airflow.

[0152] In some embodiments, the touchscreen also allows the user to control the direction of the airflow exiting the air outlet 226. For example, by touching a specific area of ​​the ring, the user can redirect the airflow in the corresponding direction.

[0153] In some embodiments, the second display interface 310 is further configured to display information regarding the temperature, direction and / or intensity of the airflow exiting the air duct outlet.

[0154] The second display interface 310 can include one or more light sources (not shown). The one or more light sources (e.g., LEDs) are configured to illuminate the second display interface 310. In one example, the second display interface 310 is configured to use different colors to visually indicate the temperature of the airflow exiting the air duct outlet. Blue can represent cooler air, indicating that the HVAC system 160 is operating in cooling mode, while red can indicate warmer or heated air. This color-based system provides an intuitive visual representation of the airflow temperature, allowing the user to quickly assess and adjust climate control settings.

[0155] It is obvious to a person skilled in the art that in some embodiments of the Fig. 2a the conical body 214 shown can be replaced by the first conical body 352.

[0156] It will now be on Fig. 4a and Fig. 4b is referenced. Fig. Figure 4a shows a cross-sectional view of an example of a second air guide outlet 400 comprising a second conical body 460. Fig. 4b shows a front view of the in Fig. 4a shown second conical body 460.

[0157] The second conical body 460 is positioned in a second air duct 404. Fig. 4a The second conical body 460 is in a first position with respect to the second air duct 404. In the first position, the second conical body 460 is spaced away from the air outlet, allowing air to flow out of the air outlet. In some embodiments, the second conical body 460 can be movable along the X-axis from the first position to a second position. In the second position, the second conical body 460 can be configured to close the air outlet, preventing air from flowing out of the air outlet.

[0158] The second conical body 460 comprises a flat circular base 408. In contrast to the ones in Fig. 2a and Fig. In addition to the conical bodies shown in 3a, the second conical body 460 has a differently shaped curved contour, which can be divided into three different areas.

[0159] In a first region 452, the cross-sectional area of ​​the second conical body 460 (from the ZY plane) increases linearly from the base until it reaches a maximum point. Subsequently, the cross-sectional area remains constant in a second region 450, resulting in a flat profile in this region. Finally, in a third region 402, which transitions smoothly from the second region, the cross-sectional area gradually tapers towards a peak 406, following a profile resembling a decaying exponential function.

[0160] The entire second conical body 460 is symmetrical along the X longitudinal axis and comprises a massive structure.

[0161] The second conical body 460, like the conical body 219 and the first conical body 352, is airtight. Thus, air is configured to flow around the second conical body 460 in a second passage 421, defined between an outer surface of the second conical body 460 and an inner surface of the second air duct 404. The direction of the airflow around the second conical body 460 is indicated by arrows 420 and 422.

[0162] The second conical body 460 is configured to define an annular opening in the second air duct 404 at a point where the cross-sectional area of ​​the second air duct 404 decreases in diameter, in order to generate an annular airflow that converges at a convergence point 401 located at a point spaced from the air outlet 226. In the region of the second conical body 460, the cross-sectional area of ​​the second air duct 404 varies such that the cross-sectional area of ​​the passage 421 (out of the ZY plane) is essentially constant (when the second conical body 460 is in the Fig. 4a is the position shown).

[0163] It is obvious to a person skilled in the art that in some embodiments of the Fig. 2a the conical body 214 shown can be replaced by the second conical body 460.

[0164] It will now be on Fig. 5a and Fig. 5b is referenced. Fig. Figure 5a shows a cross-sectional view of a third air guide outlet 500, which includes an example of a third conical body 508. Fig. 5b shows a front view of the in Fig. 5a shown air guide outlet 500.

[0165] The third conical body 508 is positioned in a third air duct 504. The third air duct 504 differs from the previously shown air ducts (in Fig. (2a to 4a) by not extending substantially linearly along the X-axis. In this embodiment, the third air duct 504 begins with a section that follows the direction of the X-axis, but then bends downwards (towards the -Z-axis). The third air duct 504 then gradually bends slightly upwards (towards the +Z-axis). In this way, the third air duct 504 follows a serpentine shape.

[0166] The third air duct 504 can follow a non-linear path to ensure it can fit around other components within the vehicle dashboard. This type of design allows the air duct 504 to be routed around structural or functional elements, such as wiring, electronics, or support brackets.

[0167] The third conical body 508 comprises a flat base 502 that tapers to a tip 506. The third conical body 508 is asymmetric about the X-longitudinal axis. The tip 506 of the third conical body 508 is spaced from the X-longitudinal axis in the -Z direction. In this way, the offset tip 506 of the third conical structure 508 is designed to align with or follow the curvature of the third air duct 504.

[0168] By ensuring that the shape and position of the tip 506 of the third conical structure 508 correspond to the bend in the air duct 504, the design minimizes airflow disturbances. This reduction of turbulence is particularly important for maintaining a consistent and undisturbed airflow. The reduction of airflow turbulence achieved through this configuration can have the additional benefit of reducing noise generated by the air outlet.

[0169] For the sake of simplicity, the nozzle will be 220 in Fig. 5a not shown. However, it is clear to the expert that nozzle 220 may be present in air duct 504.

[0170] The operation of nozzle 220 will now be carried out with reference to Fig. Described in sections 6a to 9b.

[0171] Fig. Figure 6a shows a cross-sectional view of an air guide outlet 120, with the nozzle 220 in a downward position. Fig. Figure 6b shows a rear view (viewed from the direction of arrow 208) of the air guide outlet 120 in the Fig. 6a downward position shown.

[0172] Starting from the in Fig. In the middle position shown in 2a, the nozzle 220 is rotated around the vertical Y-axis into the position shown in Fig. The downward position shown in Figure 6a is rotated. This rotational movement is enabled by the first actuator 132a in conjunction with the rack and pinion 218 mechanism. The first actuator 132a is configured to rotate the pinion 218 in a first direction. During rotation, the pinion 218 engages with the rack 222, which is arranged along the outer surface of the nozzle 220. This engagement causes the nozzle 220 to rotate downwards around the Y-axis (towards the Z-axis), thus achieving the desired position adjustment. The rack and pinion system ensures precise control of the nozzle's movement, guaranteeing smooth and accurate rotation along the defined axis.

[0173] The airflow direction in the air duct 200 when the nozzle 220 is in the downward position is schematically represented by a series of arrows 600. Air enters the air duct 200 through the air inlet 208. In the first section 202 of the air duct 200, the airflow moves essentially parallel to the X-axis. Upon impact with the nozzle 220, the airflow is redirected downwards towards the -Z-axis. The redirected air flows through the lower section of the passage 219 and is deflected by both the conical body 214 and the inner surface of the air duct 200. This deflection changes the airflow direction, causing it to move upwards towards the +Z-axis as it exits the air outlet 226.

[0174] It will now be on Fig. 7a and Fig. Reference is made to 7b. Fig. Figure 7a shows a cross-sectional view of the air guide outlet 120, with the nozzle 220 in an upward position. Fig. Figure 7b shows a rear view (viewed from the direction of arrow 208) of the air guide outlet 120 in the Fig. 7a upward position shown.

[0175] Starting from the in Fig. In the middle position shown in 2a, the nozzle 220 is rotated around the vertical Y-axis into the position shown in Fig. The nozzle 220 is rotated to the upward position shown in Figure 7a. This rotational movement is enabled by the first actuator 132a in conjunction with the rack and pinion 218 mechanism. The first actuator 132a is configured to rotate the pinion 218 in a second direction (opposite to the first). During rotation, the pinion 218 engages with the rack 222, which is arranged along the outer surface of the nozzle 220. This engagement causes the nozzle 220 to rotate upwards around the Y-axis (towards the +Z-axis), thus achieving the desired position adjustment. The rack and pinion system ensures precise control of the nozzle's movement, guaranteeing smooth and accurate rotation along the defined axis.

[0176] The airflow direction in the air duct 200 when the nozzle 220 is in the upward position is schematically represented by a series of arrows 700. Air enters the air duct 200 through the air inlet 208. In the first section 202 of the air duct 200, the airflow moves essentially parallel to the X-axis. Upon impact with the nozzle 220, the airflow is redirected upward toward the +Z-axis. The redirected air flows through an upper section of the passage 219 and is deflected by both the conical body 214 and the inner surface of the air duct 200. This deflection changes the airflow direction, causing it to move downward toward the -Z-axis as it exits the air outlet 226.

[0177] It will now be on Fig. 8a and Fig. Reference is made to section 8b. Fig. Figure 8a shows a cross-sectional view of the air guide outlet 120 in a position pointing upwards to the left. Fig. Figure 8b shows a rear view (viewed from the direction of arrow 208) of the air guide outlet 120 in the Fig. Position shown in 8a, pointing upwards to the left.

[0178] Starting from the in Fig. 7a and Fig. In the upward position shown in 7b, the nozzle 220 is moved around the Z-transverse axis into the position shown in Fig. 8a and Fig. The position shown in Figure 8b is rotated upwards and to the left. This rotation is enabled by the second actuator 132b. More specifically, the second actuator 132b drives the rotation of the pin 298, thus rotating the ring-shaped structure 299 and the nozzle 220 about the second axis (i.e., about the Z-axis). In this position, air flowing through the nozzle 220 is deflected upwards and to the left towards the +Y-axis.

[0179] It will now be on Fig. 9a and Fig. Reference is made to 9b. Fig. Figure 9a shows a cross-sectional view of the air guide outlet 120 in a neutral position to the left. Fig. Figure 9b shows a rear view (viewed from the direction of arrow 208) of the air guide outlet 120 in the Fig. Position shown in 9a to the left is neutral.

[0180] Starting from the in Fig. 8a and Fig. In the position shown in 8b, pointing upwards to the left, the nozzle 220 is rotated around the vertical Y-axis into the position shown in Fig. 9a and Fig. The position shown in Figure 9b is rotated to the left in a neutral position. This rotation is enabled by the first actuator 132a in conjunction with the rack and pinion 218 mechanism. The first actuator 132a is configured to rotate the pinion 218 in a first direction. During rotation, the pinion 218 engages with the rack 222, which is arranged along the outer surface of the nozzle 220. This engagement causes the nozzle 220 to rotate downwards around the Y-axis (towards the -Z-axis), thereby achieving the desired position adjustment. In this position, air flowing through the nozzle 220 is deflected to the left towards the +Y-axis.

[0181] To a specialist, it is clear that the nozzle 220 can be rotated into any desired position using the combined action of the first actuator 132a and the second actuator 132b. This configuration allows precise control of the nozzle's orientation, thereby enabling adjustment of the direction of the airflow exiting the air outlet 226 as needed for optimal air distribution.

[0182] It will now be on Fig. Reference is made to sections 10a to 10c.

[0183] Fig. Figure 10a shows a cross-sectional view of the first conical body 352, which shows a direction of airflow around the conical body 352 when the air guide outlet 120 is in the Fig. 2a and Fig. The middle position shown in 2b is shown.

[0184] In this central position, the nozzle 220 is essentially aligned along the X longitudinal axis, allowing the airflow to be guided symmetrically around the first conical body 352. The airflow paths indicated by arrows 1008 and 1010 show how the airflow is deflected undisturbed around the surface of the conical body 352 and the inner surface of the surrounding air duct 330. Due to the central position of the nozzle 220, the airflows are directed uniformly in all directions, producing a uniform airflow distribution around the circumference of the first conical body 352. After deflection, the airflow exits the air outlet 226 and converges at a duct control point 302, which is spaced apart from the air outlet 226. After converging at the duct control point 302, the resulting airflow flows essentially along the X longitudinal axis.

[0185] Fig. Figure 10b shows a cross-sectional view of the first conical body 352, which shows a principal direction of the airflow around the first conical body 352 when the air guide outlet 120 is in the Fig. 7a and Fig. The upward position shown in 7b is shown.

[0186] In this configuration, as the airflow continues to move around the entire surface of the first conical body 352 and the inner surface of the air duct 330, a larger volume of air is directed upwards along the path toward which the nozzle is aligned, as indicated by arrows 1000 and 1002. When the air exits the air outlet 226, the airflow converges at a convergence point (not shown). The convergence point is positioned due to the upward orientation of the nozzle 220 relative to the -Z-axis.

[0187] Fig. Figure 10c shows a cross-sectional view of the first conical body 352, which shows a principal direction of the airflow around the first conical body 352 when the air guide outlet is in the Fig. 6a and Fig. The downward position shown in 6b is shown.

[0188] In this configuration, as the airflow continues to move around the entire surface of the first conical body 352 and the inner surface of the air duct 330, a larger volume of air is directed downwards along the path toward which the nozzle is aligned, as indicated by arrows 1004 and 1006. When the air exits the air outlet 226, the airflow converges at a convergence point (not shown). The convergence point is positioned due to the downward orientation of the nozzle 220 relative to the +Z axis.

[0189] It is understood that the invention has been described above purely by way of example and that detailed modifications may be made within the scope of protection of the claims. Although the air outlet has been described with reference to specific applications in the automotive industry, it is understood that the air outlet can be used in other contexts and industries.

[0190] The methods described herein can be performed by instructions stored on a processor-readable medium.
