Description

Technical Field

[0001] The present application relates to the technical field of automobile air-conditioning systems, and in particular to an air-conditioning intake pipe, an automobile air-conditioning system and an automobile. Background Art

[0002] The car air-conditioning system is indispensable for the car. It can provide comfortable ambient temperature and fresh air for the passenger compartment. The air inlet of the car air-conditioning is connected to the air intake pipe, which leads vertically upward to the outside of the car. The car air-conditioning system is connected to the outside air through the air intake pipe. The air intake pipe has a U-shaped bend structure with a certain depth, which is mainly used to gather water entering the air intake pipe and discharge it.

[0003] In the prior art, when the air conditioning external circulation is turned on when the car is climbing a hill, water outside the car (such as rainwater, etc.) enters the air intake pipe and forms wall water on the surrounding wall of the air intake pipe. The wall water will be sucked into the air conditioning inlet by the air flow and thus enter the car. In order to prevent the wall water from entering the air conditioning port, if the U-shaped bend structure is deepened and the upper surface of the U-shaped bend structure is adjusted to a horizontal height lower than the air conditioning inlet, although the problem of wall water being sucked in can be solved, the air intake path will be changed, affecting the smoothness of the air intake, increasing wind noise, and reducing the user experience. At the same time, due to the structural change, the layout of surrounding parts is also affected, increasing costs. Therefore, this method is not practical. If the air conditioning external circulation wind force is actively reduced to reduce the suction force to prevent the wall water from being sucked in, it will affect the normal use of the car air conditioning system and cause inconvenience to the user.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of this application without substantial changes in the technical content.

[0026] See also Figure 1 , Figure 3 and Figure 4 , the present application exemplarily provides an air conditioning intake duct, comprising:

[0027] The air intake duct body has one end connected to the outside of the vehicle and the other end connected to the air inlet of the air conditioner; the air intake duct body is formed by an upper plate 5, a lower plate 8 and a side plate 7, the upper plate 5 has a U-shaped bent structure 6, and a first blocking portion 9 is provided at the bottom of the U-shaped bent structure 6 on the side away from the air inlet of the air conditioner, both ends of the first blocking portion 9 are connected to the side plate 7, and the connection between the first blocking portion 9 and the side plate 7 extends toward the lower plate 8, and a second blocking portion 10 is formed on the side plate 7, and the second blocking portion 10 protrudes in the direction away from the side plate 7.

[0028] In the air-conditioning intake duct provided in the present application, the wall water entering the intake duct is blocked by the first blocking part 9 and the second blocking part 10. When the car is climbing, the wall water will be sucked into the air-conditioning intake port under the influence of the air flow. The first blocking part 9 blocks water at the bottom of the U-shaped bend structure 6, and the second blocking part 10 blocks water at the side plate 7. The wall water is blocked and drips and collects on the lower plate 8 and will not enter the air-conditioning intake port. Water vapor separation can be achieved without affecting the air intake volume and without changing the layout of surrounding parts, thereby meeting the air intake volume requirements and improving the user experience.

[0029] Please note that Figure 1 and Figure 2 , Figure 1 This is the external schematic diagram of the overall structure of the air-conditioning intake pipe. Figure 2 It is a cross-sectional diagram of AA of the existing air-conditioning intake pipe under the condition of a car climbing a hill. Water outside the car will enter the air-conditioning intake pipe from the air-intake grille 2 and the water inlet areas 4 on both sides, and form wall water on the surrounding wall of the air-conditioning intake pipe. The U-shaped bend structure 6 in the air-conditioning intake pipe has a certain depth, which can block the wall water. The wall water is blocked and drips to the bottom of the air-conditioning intake pipe and is discharged from the drain port 3 at the bottom. However, under the condition of a car climbing a hill and the air-conditioning external circulation is turned on, the air-conditioning intake pipe is also in a tilted state due to the overall tilt of the vehicle. At this time, the wall water will pass over the U-shaped bend structure 6 and be sucked into the air-conditioning intake port by the air flow. The U-shaped bend structure 6 is affected by its own structure and cannot block all the wall water, causing water to enter the air-conditioning, affecting the normal operation of the air-conditioning system.

[0030] In this embodiment, if Figure 3 As shown, the first blocking portion 9, the second blocking portion 10 and the upper plate 5 are an integrally formed structure. It can be understood that the air-conditioning air intake pipe is integrally formed by a blow molding manufacturing process, without adding other components, thereby reducing production costs.

[0031] Specifically, the first blocking portion 9 is a wave-shaped structure, which has at least one wave, and the wave is a V-shaped structure with an arc at the bottom. The second blocking portion 10 is a U-shaped structure, and the wave corresponds to the U-shaped structure. A blow molding manufacturing process is used to form a wave-shaped structure at the bottom of the U-shaped curved structure 6 on the side away from the air inlet of the air conditioner, and a U-shaped structure is formed on the side panel 7. When the car is climbing, the wall water is blocked by the wave-shaped structure at the bottom of the U-shaped curved structure 6 and by the U-shaped structure on both sides of the side panel 7, and drips along the wave-shaped structure and the U-shaped structure to the lower plate 8, thereby achieving the purpose of water vapor separation and preventing the wall water from being sucked into the air inlet of the air conditioner by the airflow.

[0032] In detail, the wave width is 5 to 15 mm, the height difference between the wave crests and troughs is 4 to 10 mm, the surface of the second blocking portion 10 is an arc-shaped transition surface, and the width of the U-shaped structure gradually decreases toward the lower plate 8. Through the gradually decreasing U-shaped structure and the transition surface, after the wall water is blocked by the second blocking portion 10, the wall water drips and slides down the second blocking portion 10 faster, thereby improving the water vapor separation efficiency.

[0033] In some embodiments, Figure 4 As shown, the first blocking portion 9 and the second blocking portion 10 are separate structures from the upper plate 5. It is worth noting that the air-conditioning air intake pipe is manufactured by blow molding, and the upper plate 5 is cut off from the bottom of the U-shaped bend structure 6 on the side away from the air inlet of the air conditioner, and the air-conditioning air intake pipe is divided into two parts. The first blocking portion 9 and the second blocking portion 10 are spliced ​​with the upper plate 5 by splicing.

[0034] Specifically, the first blocking part 9 and the second blocking part 10 are both plate-like structures. When the car is climbing a slope, the wall water is blocked by the first blocking part 9 at the bottom of the U-shaped bend structure 6 and by the second blocking part 10 on both side panels 7, and drips along the first blocking part 9 and the second blocking part 10 to the lower panel 8, thereby achieving the purpose of water vapor separation and preventing the wall water from being sucked into the air inlet of the air conditioner by the air flow.

[0035] In this embodiment, a drain port 3 for drainage is provided on the lower plate 8. When the wall water is blocked by the first blocking part 9 and the second blocking part 10, it drips onto the lower plate 8 and is discharged through the drain port 3, thus completing the water vapor separation.

[0036] In this embodiment, the air intake duct of the air conditioner also includes a lower decorative panel 1, which is arranged on the upper plate 5. An air intake grille 2 is arranged on the lower decorative panel 1, and the air intake grille 2 covers the air intake port of the air intake duct body. The air intake duct body is connected with the outside of the vehicle through the air intake grille 2. At the same time, water outside the vehicle will enter the air intake duct of the air conditioner from the air intake grille 2 and the water inlet area 4 on both sides, and form wall water on the surrounding wall of the air intake duct.

[0037] In another embodiment, the present application also provides an automobile air-conditioning system, including an air-conditioning air inlet and the above-mentioned air-conditioning air inlet pipe, wherein an air outlet of the air-conditioning air inlet pipe is connected to the air-conditioning air inlet.

[0038] In another embodiment, the present application also provides a car, comprising the above-mentioned car air-conditioning system.

[0039] In summary, in the air-conditioning intake duct provided in the present application, the wall water entering the air intake duct is blocked by the first blocking part 9 and the second blocking part 10. When the car is climbing, the wall water will be sucked into the air-conditioning air intake port under the influence of the airflow. The first blocking part 9 blocks water at the bottom of the U-shaped bend structure 6, and the second blocking part 10 blocks water at the side plate 7. The wall water is blocked and drips and collects on the lower plate 8 and will not enter the air-conditioning air intake port. Water vapor separation can be achieved without affecting the air intake volume and without changing the layout of surrounding parts, thereby meeting the air intake volume requirements and improving the user experience.

[0040] The above embodiments are merely illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
