Description

Technical Field

[0001] This application relates to the field of vehicle structure technology, specifically to an air conditioning outlet structure and a vehicle including the outlet structure. Background Technology

[0002] In cold seasons such as autumn and winter, the vehicle's air conditioning system can provide warm air to the doors. The car also has dedicated foot vents to blow warm air onto the feet and prevent them from feeling cold. For example, there is usually a foot vent in the driver's seat, blowing warm air towards the driver's right foot or the area between the feet. However, airflow cannot easily cover the seams between the door and the passenger compartment. As the door seals age or due to gaps in the seal, cold air inevitably enters through these gaps, especially in extremely cold or windy weather. This can cause the driver's left foot to feel cold, and an imbalance in temperature between the left and right feet, commonly known as "uneven feet," affecting the driver's foot comfort. Summary of the Invention

[0003] In view of this, this application aims to provide an air conditioning outlet structure that solves the problem of cold air leakage from door gaps causing the left foot to freeze in the driver's cab and the problem of temperature imbalance between the left and right feet, thereby improving the comfort of the left foot and the temperature balance between the left and right feet.

[0004] This application provides an air conditioning vent structure suitable for installation on a vehicle body. The air conditioning vent structure includes an air duct with a plurality of air outlets arranged at intervals along the axial direction. The plurality of air outlets include an isolation air outlet located near the vehicle door and a foot-blowing air outlet located on the side of the isolation air outlet away from the vehicle door. The isolation air outlet is configured to blow air horizontally or downward at an angle, and at least part of the airflow blows towards the outside of the driver's left foot, forming an isolation air curtain between the vehicle door and the driver's left foot.

[0005] In one possible implementation, the vehicle's dashboard includes at least a rear skid plate located at the steering wheel and a lower skid plate extending towards the floor.

[0006] The isolation vent is located on the rear guard plate and above the area of ​​the lower guard plate where the footrest is located, and is configured to blow air at an angle downward toward the driver's left heel area, so that the airflow bends toward the inside of the left foot in the heel area.

[0007] In one possible implementation, the angle between the axis of the isolation vent and the plane of the vehicle floor is 60°-70°.

[0008] In one possible implementation, the foot-blowing vent further includes a first foot-blowing vent disposed adjacent to the isolation vent and located on the side of the isolation vent away from the vehicle door.

[0009] The first foot air vent directs air towards the vehicle floor and its axis is tilted towards the side of the vehicle door. The first foot air vent is configured to blow air towards the footrest pedal to deliver air to the area of ​​the driver's left foot instep and to merge with the isolation air curtain after passing through the instep area.

[0010] In one possible implementation, the foot vent further includes a second foot vent and a third foot vent located on the side of the isolation vent away from the vehicle door. The third foot vent is configured to deliver air to the accelerator pedal. The second foot vent is located between the first foot vent and the third foot vent. The axis of the second foot vent is inclined toward the side of the vehicle door, and the inclination angle is smaller than the inclination angle of the first foot vent.

[0011] In one possible implementation, the first foot blowing vent, the second foot blowing vent, and the third foot blowing vent are disposed on the lower guard plate of the dashboard;

[0012] In the vehicle height direction, the first foot blowing vent is located above the area of ​​the lower guard plate where the clutch pedal is located, the second foot blowing vent is located above the brake pedal, and the third foot blowing vent is located above the accelerator pedal.

[0013] In one possible implementation, the air outlet duct includes a first pipe segment extending along the width direction of the vehicle body and a second pipe segment extending from the end of the first pipe segment in the length direction of the vehicle body.

[0014] The first foot blowing vent, the second foot blowing vent, and the third foot blowing vent are all located on the radial bottom side of the first pipe section and are positioned towards the vehicle floor. The isolation vent is located at the end of the second pipe section and is inclined downwards towards the vehicle floor.

[0015] In one possible implementation, the axis of the first foot blowing vent is tilted toward the side of the car door at an angle of 45°-55°.

[0016] And / or, the axis of the second foot blowing vent is tilted toward the side of the car door and the tilt angle is 15°-25°;

[0017] And / or, the axis of the third foot blowing vent is set perpendicular to the vehicle floor.

[0018] In one possible implementation, the air volume ratio of the isolation vent, the first foot blowing vent, the second foot blowing vent, and the third foot blowing vent is A:B:C:D, where A is 2.5-3.5, B is 9.5-10.5, C is 1.5-2.5, and D is 4.5-5.5.

[0019] In one possible implementation, the isolation vent is provided with an annular air guide groove formed by air guide blades, and the air guide groove is a reduced structure along the air outlet direction.

[0020] In one possible implementation, a temperature sensor is also provided for detecting the temperature at the door gap. The temperature sensor is configured to be electrically connected to the vehicle controller so that the vehicle controller adjusts the air volume and wind speed based on temperature feedback.

[0021] This application also provides a vehicle, including a body, wherein the body is provided with an air conditioning vent structure as described in any of the preceding claims.

[0022] The air conditioning vent structure provided in this application features a dedicated air vent near the car door. This air vent is positioned horizontally or tilted downwards towards the driver's left foot area, creating an air curtain between the car door and the driver's left foot. This air curtain isolates the driver's left and right feet, especially the left foot, from the car door with warm air, blocking cold air from entering through the door gaps and preventing it from blowing directly on the left foot. Simultaneously, the air curtain, combined with warm air blown towards the feet from other foot vents, creates a warm, enveloping area around the driver's feet, effectively addressing the issues of uneven foot temperature and discomfort caused by cold air entering through the door gaps on the left foot.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please refer to the attached document. Figure 1-7 This application provides an air conditioning outlet structure, including an air outlet duct 10. The air outlet duct 10 has a plurality of air outlets arranged axially at intervals. The plurality of air outlets include an isolation air outlet 104 and a foot-blowing air outlet. The isolation air outlet 104 is located near the vehicle door 40, and the foot-blowing air outlet is located inside the isolation air outlet 104 (referring to the side of the isolation air outlet 104 away from the vehicle door 40 in the vehicle body width direction). The foot-blowing air outlet blows air towards the vehicle floor panel to deliver air to the driver's feet. The isolation air outlet 104 is configured to blow air horizontally or downwards at an angle, and at least a portion of the airflow blows towards the outside of the driver's left foot, forming an isolation air curtain between the vehicle door 40 and the driver's left foot. Figure 6 As shown.

[0035] This design, by placing a dedicated air vent 104 near the door 40 and directing the air vent 104 horizontally or tilted downwards towards the driver's left foot area, creates an air curtain between the door 40 and the driver's left foot. This isolates the driver's left and right feet, especially the left foot, from the door 40 with warm air, blocking cold air from entering the vehicle through the door gaps and preventing it from blowing directly on the left foot. At the same time, the air curtain, combined with the warm air blown towards the feet from other foot vents, creates a warm, enveloping area around the driver's feet, effectively solving the problems of uneven foot temperature and discomfort caused by cold air entering through the door gaps on the left foot.

[0036] Similarly, in the hot summer, the isolation vent 104 can effectively block the hot air entering through the door gap, so that the temperature of the driver's left and right feet is balanced, avoiding discomfort caused by the left foot not feeling cool.

[0037] There are various locations where the air vent 104 can be installed, such as on the dashboard in the driver's cab, on the trim panel of the door frame, or on the interior panel of the driver's cabin, etc.

[0038] For example, the isolation vent 104 is installed on the dashboard, which can shorten the length of the air conditioning duct and facilitate its layout.

[0039] Specifically, the dashboard includes, in sequence, an upper guard plate near the windshield, a middle guard plate with an instrument display area, a rear guard plate 20 located at the steering wheel, and a lower guard plate 30 extending towards the floor. The following description primarily uses the isolation of cold air in cold weather as an example, but it is undeniable that in summer, it can improve the coolness of the driver's left foot, just as it does in winter.

[0040] The air vent 104 can be installed on the lower guard plate 30 and blow air horizontally along the length of the vehicle body. For example, the axis of the air vent 104 is parallel or substantially parallel to the length of the vehicle body, and the height of the air vent 104 is low, close to the floor. In this way, air is blown directly to the outside of the driver's left foot, forming an air curtain between the door 40 and the outside of the driver's left foot, isolating the cold air entering from the door gap outside the foot area; at the same time, in the width direction of the vehicle body, the airflow inside the air curtain will also blow to the driver's left foot, warming the left foot.

[0041] Alternatively, the air vent 104 is positioned on the rear bumper 20, above the footrest pedal (the pedal on some models for the left foot to rest on), or above the area on the vehicle where the footrest pedal can be installed. It is configured to blow air downwards at an angle towards the driver's left heel area. Figure 7 As shown; the axis of the isolation vent 104 has an angle with both the horizontal plane and the first vertical plane, wherein the first vertical plane is a plane that includes the width direction of the vehicle body and the height direction of the vehicle body.

[0042] The air vent 104 is located at the front of the vehicle, on the rear guard plate 20 at a certain distance from the floor. Specifically, it blows air from the outside of the driver's left foot toward the rear of the vehicle, in the area of ​​the left heel. This downward-sloping airflow not only forms an air curtain that isolates cold air on the outside of the left foot, but also causes the airflow to turn from the back of the heel (slightly behind the heel) toward the right foot (the airflow flows inward after being no longer blocked by the left foot in the width of the vehicle). At the same time, the airflow hits the floor in the heel area (directly outside the heel or slightly behind the heel) and then spreads upwards, so that the airflow blows onto the ankle above the left heel and even the calf area, forming an L-shaped enveloping air curtain for the driver's left foot.

[0043] For example, the angle between the axis of the isolation vent 104 and the vehicle floor is 60°-70°. This ensures that the airflow is directed towards the left heel area, so that the airflow bends towards the inside of the left foot after passing the outside of the left foot, and then diagonally spreads upward after contacting the floor, thereby blowing to the ankle and calf area above the left heel.

[0044] For example, the axis of the isolation vent 104 may be parallel to the second vertical plane, or it may have an angle tilted toward the side of the vehicle door, the angle being no greater than 20°.

[0045] For example, in the width direction of the vehicle body, the axis of the isolation vent 104 is flush with or has a distance of no more than 2 cm from the edge of the footrest near the door 40 (for ease of reference, this side edge is referred to as the left edge based on the driving direction). The edge of the isolation vent 104 near the door 40 can be located to the left of the left edge of the footrest, that is, between the left edge of the footrest and the door 40.

[0046] In this way, the airflow blown out by the isolation vent 104 may blow directly to the slightly outer part of the left foot, or it may blow obliquely over the back of the left foot to the outside of the left foot. In both cases, at least some airflow will pass over the outside of the left foot to form an air curtain. It will bend inward at the heel and spread upward after hitting the floor of the vehicle, forming an L-shaped wrap-around isolation air curtain that can reach the ankle and calf area of ​​the left foot.

[0047] Furthermore, in some embodiments, the foot-blowing vent among the multiple air outlets includes a first foot-blowing vent 101 disposed adjacent to the isolation vent 104 and located on the side of the isolation vent 104 away from the vehicle door 40. The first foot-blowing vent 101 is inclined downward toward the vehicle floor and is inclined toward the side of the vehicle door 40, that is, the first foot-blowing vent 101 has an angle with the horizontal plane where the vehicle floor is located. The first foot-blowing vent 101 is configured to blow air toward the footrest (such as the rear side of the footrest), with the purpose of delivering air to the area of ​​the driver's left instep, so that the airflow continues to flow to the outside of the left foot after passing the instep area, and merges with the air blown out of the isolation vent 104, together forming an isolation air curtain.

[0048] Obviously, please refer to the appendix together. Figure 6 and attached Figure 7The airflow from the first foot-blowing vent 101 blows on the back of the left foot and merges with the isolation air curtain, which not only enhances the air volume and formation effect of the isolation air curtain, but also enlarges the isolation air curtain, so that the isolation air curtain covers the instep area. That is, the air curtain formed by the first foot-blowing vent 101 and the isolation vent 104 blows from the inside of the left foot to the left foot, flows through the back of the left foot to the outside of the left foot, and blows along the left foot to the heel. It will tilt upwards behind the heel and turn back to the inside of the left foot, blowing towards the ankle and calf, thus forming a kind of full-coverage air curtain for the left foot.

[0049] The foot-blowing vents among the multiple air outlets also include a second foot-blowing vent 102 and a third foot-blowing vent 103 located on the side of the isolation vent 104 away from the door 40. The second foot-blowing vent 102 is located between the first foot-blowing vent 101 and the third foot-blowing vent 103. That is, from the door 40 along the width of the vehicle body, the arrangement order of the multiple air outlets is the isolation vent 104, the first foot-blowing vent 101, the second foot-blowing vent 102, and the third foot-blowing vent 103. The combination of the isolation vent 104 and the four foot-blowing vents, along with the isolation air curtain that blocks cold air from the door gaps, can create a large warm air zone in the area where the driver's feet are located, ensuring the temperature of the feet and improving comfort.

[0050] The third foot vent 103 is configured to blow air towards the accelerator pedal, while the second foot vent 102 is configured to blow air between the first foot vent 101 and the third foot vent 103, for example, towards the brake pedal. Thus, the third foot vent 103 can blow air from above the right foot towards the instep of the right foot, warming the right foot, while the second foot vent 102 blows air into the area between the left and right feet, warming both feet from between the feet.

[0051] Preferredly, the axis of the second foot vent 102 is tilted towards the side of the door 40, but the tilt angle is smaller than that of the first foot vent 101 towards the door 40. Thus, the first foot vent 101 blows air towards the footrest pedal, while the airflow is directed to the back of the driver's left foot and merges with the airflow from the first foot vent 101. The airflow from the second foot vent 102 is more directed towards the inside of the left foot. In this way, the airflow from the isolation vent 104, the first foot vent 101, and the second foot vent 102 can completely surround and envelop the left foot, forming an effective enveloping air curtain, which can effectively warm the left foot in cold weather.

[0052] Specifically, the first foot-blowing vent 101, the second foot-blowing vent 102, and the third foot-blowing vent 103 are disposed on the lower guard plate 30 of the dashboard; the lower guard plate 30 refers to the plate connecting the vehicle floor and the rear guard plate 20, which is inclined towards the front of the vehicle relative to the rear guard plate 20. The first foot-blowing vent 101, the second foot-blowing vent 102, and the third foot-blowing vent 103 are opened on the rear guard plate 20 and can directly blow air toward the vehicle floor. The axis of the vent can have no angle or a small angle of no more than 20° with the second vertical plane, which is a plane including the length direction and the width direction of the vehicle body.

[0053] Along the vehicle body height, the first foot air vent 101 is positioned above the area where the clutch pedal can be located, the second foot air vent 102 is positioned above the brake pedal, and the third foot air vent 103 is positioned above the accelerator pedal. Manual transmission vehicles are equipped with a clutch pedal, while the clutch pedal area is empty in automatic transmission vehicles. The first foot air vent 101, positioned above the clutch pedal area and tilted towards the door 40, blows air towards the footrest, directing the airflow to the instep of the left foot.

[0054] like Figure 2 As shown, the air outlet duct 10 includes a first pipe section 11 extending along the width direction of the vehicle body and a second pipe section 12 extending from the end of the first pipe section 11 in the length direction of the vehicle body.

[0055] The first foot-blowing vent 101, the second foot-blowing vent 102, and the third foot-blowing vent 103 are all located on the radial bottom side of the first pipe section 11 (referring to the side of the first pipe section 11 that faces the vehicle floor radially upwards) and are positioned towards the vehicle floor. For example, the first foot-blowing pipe section, the second foot-blowing pipe section, and the third foot-blowing pipe section extend from the radial bottom side of the first pipe section 11. The first foot-blowing vent 101 is formed at the end of the first foot-blowing pipe section, the second foot-blowing vent 102 is formed at the end of the second foot-blowing pipe section, and the third foot-blowing vent 103 is formed at the end of the third foot-blowing pipe section. The isolation vent 104 is located at the end of the second pipe section 12 and is inclined downwards towards the vehicle floor.

[0056] The first foot air vent 101 is located above the accelerator pedal, with its axis tilted towards the side of the door 40 at an angle a1 of 45°-55° (a1 refers to the angle between the axis of the first foot air vent 101 and the first vertical plane; the angle between the axis of the first foot air vent 101 and the plane where the vehicle floor is located is 90°-a1, i.e., 35°-45°). In this way, the first foot air vent 101 can blow airflow to the area above and behind the footrest pedal, that is, blow air towards the back of the driver's left foot.

[0057] The second foot air vent 102 is located above the brake pedal, with its axis tilted towards the side of the door 40 at an angle a2 of 15°-25° (a2 refers to the angle between the axis of the second foot air vent 102 and the first vertical plane; the angle between the axis of the second foot air vent 102 and the plane where the vehicle floor is located is 90°-a2, i.e., 65°-75°). Thus, the air blown by the second foot air vent 102 is more biased towards the inside of the left foot, enhancing the full-coverage air curtain effect of the left foot.

[0058] The third foot vent 103 is located above the accelerator pedal area, and its axis can be perpendicular to the plane of the vehicle floor. In this way, it can directly deliver air to the instep of the driver's right foot, effectively warming the right foot.

[0059] To optimize airflow distribution and balance foot temperature across the driver's seat, the airflow ratio of the four vents can be adjusted. For example, the airflow ratio of the isolation vent 104, the first foot-blowing vent 101, the second foot-blowing vent 102, and the third foot-blowing vent 103 is A:B:C:D, where A is 2.5-3.5, B is 9.5-10.5, C is 1.5-2.5, and D is 4.5-5.5. Setting the airflow according to this ratio ensures effective air curtain isolation and a fully enclosed foot-warming effect. Balanced airflow and temperature also reduce ineffective airflow and lower air conditioning energy consumption.

[0060] Furthermore, the air conditioning vent structure is also equipped with a temperature sensor for detecting the temperature at the door seams. The temperature sensor is electrically connected to the vehicle controller, allowing the vehicle controller to adjust the airflow and speed based on temperature feedback. By detecting the temperature at the door seams using a dedicated temperature sensor, it is equivalent to detecting the amount of cold air entering. Based on this, the airflow and speed of the isolation vent 104, or the isolation vent 104 and each footwell vent, can be adjusted more quickly to optimize the temperature of the door 40, optimize the temperature of the driver's foot area, reduce temperature fluctuations, and reduce driver discomfort.

[0061] For example, each air outlet can be equipped with a guide vane, which can be fixed or rotatable.

[0062] For example, an annular air guide trough formed by guide vanes is provided at the isolation air outlet 104. The air guide trough has a reduced structure along the air outlet direction, and the inclination angle of the side wall is 15°-20°. The reduced air guide trough formed by the inclined guide vanes can also be called a reduced air outlet, which can enhance the convergence of the blown air. Setting a reduced structure at the isolation air outlet 104, where an isolation air curtain needs to be formed, can enhance the formation effect of the isolation air curtain and strengthen the blocking effect on cold air from the door gap.

[0063] Each foot-blowing vent can be equipped with either fixed or rotating air guide vanes. The rotating air guide vanes allow for adjustment of the airflow from each vent, enabling the driver to adjust the airflow according to their temperature requirements and improving convenience.

This vehicle then possesses the structural configuration and corresponding beneficial effects of the above embodiments, which will not be repeated here.
