Description

[0002] Currently, the foot duct in a car's cockpit connects the air conditioner to the air outlet via a PE plastic tube. Warm air is conducted through the foot duct through the outlet and blown into the cab. The outlet typically features a decorative grille, or angled horizontal blades that guide air, directing warm or cold air toward the feet. The decorative grille directs warm or cold air in the direction of the foot duct, which determines the outlet angle. The horizontal blades direct warm or cold air in the direction of their guides, with the outlet angle dependent on the inclination of the horizontal blades. However, this approach presents the following issues:

[0003] The driver's feet are always in active state during driving (the left foot is on the footrest or clutch pedal, and the right foot is on the accelerator pedal or brake pedal). The cold / warm air direction cannot completely cover the driver's feet. After passing through the air outlet, the cold / warm air generally blows to the center of the foot's range of activity, and the air falls on the ankles or calves.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0039] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0040] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0042] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0043] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0044] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0045] It should be understood that:

[0046] Since the vehicle decorative grille makes the warm air or cold air blow out along the outlet direction of the foot blowing air duct 4, the outlet direction of the foot blowing air duct 4 determines the outlet angle; Figure 1The hot or cold air is blown out along the fixed direction of the air outlet. However, the driver's feet are usually mobile during driving, and the fixed direction of the air outlet results in a poor sense of temperature increase or decrease for the driver.

[0047] If a structure that can adjust the wind direction is directly added, and a manually adjustable dial-back structure similar to the instrument panel air outlet is set at the air outlet of the original foot-blowing air duct 4, the following problems will occur:

[0048] First, the increase in structure increases the cost and installation process;

[0049] Secondly, since the air outlet is located at the position of the clutch pedal, there will be no safety impact if it is adjusted when the vehicle is stopped. However, during driving, the driver is required to tilt or make other posture fluctuations. During this process, the driver's eyes are away from the road. This is a dangerous posture and should not be adopted.

[0050] Thirdly, in the process of adjusting fluctuations, it can only deal with one position and cannot guide and distribute wind at two positions at the same time.

[0051] Therefore, based on the above problems, the structure of the present application is proposed, which can achieve simultaneous air guidance at both the footrest and the clutch pedal without the need for adjustment, thereby ensuring driving safety.

[0052] The foot-blowing duct air distribution device can be installed in either the driver's seat or the front passenger seat. The vehicle being loaded can be, but is not limited to, a car, truck, or van, or even an airplane. In other words, in situations where a cockpit is required to provide warm or cool air, the foot-blowing duct 4 directs the vehicle's air conditioning air to the driver's feet.

[0053] Furthermore, according to actual experience in the cab, the best experience is when the air is blown towards the toes and insteps of the feet. To solve the problem that the foot-blowing air duct 4 cannot meet the driver's foot-blowing requirements in different driving postures, a new air outlet structure is designed to ensure that the warm air is blown towards the feet where the wind feels best in different driving postures.

[0054] An embodiment of the present application provides a foot-blowing air duct air distribution device and a vehicle to solve the problem in related technologies that the driver's feet are always active during driving, resulting in the fixed grille and transverse blades not having the air blowing point in the optimal blowing area, and the driver's body feeling of heating up or cooling down is poor.

[0055] In the accompanying drawings: mark a is a footrest; mark b is a clutch pedal; mark c is the left foot; mark d is the right foot; mark e is an existing one-way air guide blade; mark f is a vehicle.

[0056] See also Figure 1-Figure 5 , a foot-blowing air duct air distribution device, comprising:

[0057] A plurality of first air guide blades 1 and second air guide blades 2 are connected vertically and horizontally to form an air distribution structure, which is used to be arranged at the air outlet of the foot blowing air duct 4;

[0058] Among them, the first air guide blades 1 extend horizontally and are spaced apart in the longitudinal direction; a plurality of second air guide blades 2 spaced apart laterally form a first air distribution channel for distributing air toward the clutch pedal with a portion of the first air guide blades 1, and form a second air distribution channel for distributing air toward the footrest with another portion of the first air guide blades 1.

[0059] The first air distribution channel formed above directs part of the wind to the clutch, and the second air distribution channel directs the other part of the wind to the footrest, so that the driver's feet can receive the best wind regardless of whether they are at the clutch position or at the footrest. In addition, the above air distribution structure does not require adaptive adjustment. Simply using a fixed design structure can enhance the driver's body temperature increase or decrease and ensure driving safety.

[0060] Furthermore, the specific connection form of the first air guide blade 1 and the second air guide blade 2 is described in detail:

[0061] Each second wind guide blade 2 includes a longitudinal straight portion 200 and a first inclined guide portion 201 and a second inclined guide portion 202;

[0062] In the longitudinal direction, the longitudinal straight portion 200 is provided with a first inclined guide portion 201 and a second inclined guide portion 202 from top to bottom; in the transverse direction, the first inclined guide portion 201 and the second inclined guide portion 202 are respectively located on both sides of the longitudinal straight portion 200.

[0063] The above structure can achieve the purpose of simultaneously distributing the airflow to the clutch position and the footrest position through the positioning and guidance of the first inclined guide portion 201 and the second inclined guide portion 202. The first air guide blade 1 is installed at an angle on the vehicle so that the first air guide blade 1 guides the air downward, but it can also be arranged at an angle.

[0064] However, in the actual driving process, according to the placement of the feet and the length of time they stay in different positions, since the driver's feet stay on the footrest for a long time and the footrest is far from the air outlet, it is necessary to divide the weights in detail. Therefore, the cross-sectional area ratio of the first air distribution channel and the second air distribution channel is 2:3, that is, Figure 3 As shown, the width ratio of the upper and lower horizontal air vents is set to 2:3, where h1:h2 is 2:3. This further enhances the heating experience.

[0065] In some preferred embodiments, reference Figure 2-Figure 5 For the above air distribution structure, the following specific settings are required to better guide or distribute the air in different directions, specifically:

[0066] In the axial direction of the air outlet of the foot blowing air duct 4, the first air guide blade 1 has a windward end and a leeward end surface;

[0067] The leeward end surface of the longitudinal straight portion 200 is located on the same plane as the leeward end surface of the first wind guide blade 1; the windward end surface of the longitudinal straight portion 200 is connected to the leeward end surfaces of the first inclined guide portion 201 and the second inclined guide portion 202; the windward end surfaces of the first inclined guide portion 201 and the second inclined guide portion 202 are located on the same plane as the windward end surface of the first wind guide blade 1; this ensures that it is an integral structure and there is no misalignment.

[0068] The windward side of the first inclined guide portion 201 is closer to the clutch pedal, and the leeward side is further away from the clutch pedal; the windward side of the second inclined guide portion 202 is closer to the footrest, and the leeward side is further away from the footrest. The above structure specifically explains the reason for directing wind in different directions. The inclination angles of the first inclined guide portion 201 and the second inclined guide portion 202 can be different or the same. They are designed based on the above-mentioned situation that the wind blowing towards the toes and insteps of the human body is the best experience.

[0069] Furthermore, since the undercut at the intersection of the vertical and horizontal connection of the first air guide blade 1 and the second air guide blade 2 will have a negative impact on the air guide, in order to ensure the normal demolding of the air outlet, the undercut at the intersection of the horizontal and vertical blades is locally treated with glue reduction to avoid affecting the wind direction, as follows:

[0070] A first trapezoidal guide groove 203 is provided on the first wind guide blade 1 connected to the first inclined guide portion 201 and close to the windward side of the first inclined guide portion 201. The length of the bottom side of the first trapezoidal guide groove 203 close to the windward end surface of the first wind guide blade 1 is greater than the length of the other bottom side.

[0071] A second trapezoidal guide groove 204 is provided on the first wind guide blade 1 connected to the second inclined guide portion 202 and close to the windward side of the second inclined guide portion 202; the length of the bottom side of the second trapezoidal guide groove 204 close to the windward end surface of the first wind guide blade 1 is greater than the length of the other bottom side.

[0072] The length of the bottom side of the first trapezoidal guide groove 203 close to the windward end surface of the first air guide blade 1 is smaller than the length of the bottom side of the second trapezoidal guide groove 204 close to the windward end surface of the first air guide blade 1; of course, the sizes of the first trapezoidal guide groove 203 and the second trapezoidal guide groove 204 can also be equal, but since the required air volume of the foot pedal is large, the first unequal form is the best form.

[0073] It should be understood that the above air distribution structure is made of plastic, which is low in cost and simple to manufacture. Therefore, through the above specific structural description, the present foot-blowing air duct air distribution device is designed from multiple perspectives, including the direction of air distribution, the amount of air distribution, and the reduction of the resistance coefficient of air distribution (i.e., the provision of multiple trapezoidal guide grooves), ultimately achieving the goal of ensuring that warm air reaches the optimal position of the feet in different postures.

[0074] In some preferred embodiments, the air distribution structure can be directly arranged inside the foot-blowing air duct 4. However, in order to facilitate the fixed installation of the foot-blowing air duct 4, the following designs are also available:

[0075] The foot-blowing duct air distribution device also includes a hood 3, which is connected to the foot-blowing duct 4. The hood 3 is annular and defines a ventilation channel. The outer periphery of the air distribution structure is connected to the inner wall of the ventilation channel. The hood 3 includes an annular tube 300, which is provided with a vehicle body connection edge 301 on its outer periphery. This edge 301 is provided with connecting screw holes or latches. The interior of the annular tube 300 is designed to plug into the foot-blowing duct 4. The hood 3 and the air distribution structure are integrally formed, making it easy to install and secure.

[0076] Furthermore, to further enhance the air separation effect, a third trapezoidal guide groove and a fourth trapezoidal guide groove are provided on the inner wall of the hood 3. The third trapezoidal guide groove is identical to the first trapezoidal guide groove 203; the fourth trapezoidal guide groove is identical to the second trapezoidal guide groove 204. This enhances the air separation effect.

[0077] The present application also proposes a vehicle, which includes: the above-mentioned foot-blowing air duct air distribution device.

[0078] The first air distribution channel formed above directs a portion of the air to the clutch, while the second air distribution channel directs another portion of the air to the footrest. This ensures that the driver's feet receive optimal airflow regardless of whether they are located at the clutch or the footrest. Furthermore, the above air distribution structure does not require adaptive adjustment; simply utilizing a fixed design can enhance the driver's sense of warming or cooling, ensuring driving safety. The design is based on multiple directions, including the direction of air distribution, the amount of air distribution, and the reduction of the drag coefficient (i.e., the provision of multiple trapezoidal guide grooves), ultimately achieving the goal of ensuring that warm air reaches the optimal foot position in different postures.

[0079] This application also provides an example of a specific application and a description of comparative experiments:

[0080] CFD simulation analysis and comparison

[0081] Reference Attachment Figure 5-Figure 8This is the CFD foot-blowing speed streamline diagram. According to simulation analysis and comparison, by dividing the wind longitudinally to the left and right sides, the foot can be blown by wind in both positions. By adjusting the air outlet ratio, the wind feeling of the foot in the two positions can be made equivalent.

[0082] refer to Figure 9 , which is a summary of the actual vehicle verification evaluation of different human bodies

[0083] Figure 9 This is a summary of the experience evaluation of the air distribution schemes for people of different sizes. According to the test evaluation results, it can be seen that Scheme 3 has the best experience. By dividing the air vertically and adjusting the air outlet ratio, the foot blowing experience is significantly improved.
