Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an air intake pipe assembly and a vehicle. Background Art

[0002] Car air conditioning is a ventilation device that is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the optimal state, provide a comfortable riding environment for drivers and passengers, reduce travel fatigue, create good working conditions for drivers, and play an important role in ensuring safe driving.

[0003] When the air conditioner is turned on the external circulation mode, the outside air will enter the air conditioning box from the air conditioning intake pipe under the front windshield of the vehicle, and enter the car after being filtered by the air conditioning filter, thereby regulating the temperature in the car.

[0004] However, when the car's wading depth is too great, water may flow into the air conditioner through the external circulation intake pipe, or even into the interior of the car, which will not only affect the air intake efficiency of the air conditioner, but may also damage components in the vehicle. Utility Model Content

[0005] To solve the above problems, the present application provides an air intake pipe assembly, in which an air intake cover is provided in the air intake pipe assembly to prevent water from penetrating into the interior of the air conditioner, thereby improving the air intake efficiency and service life of the air conditioner.

[0006] In addition, the present application also provides a vehicle equipped with the intake pipe assembly, which specifically includes the following solutions:

[0007] In a first aspect, the present application provides an air intake duct assembly, which is arranged between an air-conditioning box and a vehicle body. The air intake duct assembly includes an air intake duct, an air intake cover and at least one motor. The air intake duct is suitable for connecting the air-conditioning box with the outside world. The air intake cover is rotatably connected to the air intake duct. The motor is used to drive the air intake cover to rotate relative to the air intake duct to open or isolate the air intake duct.

[0008] The air intake pipe assembly of the present application is connected to the air intake pipe by rotating the air intake cover, so that when the vehicle is in wading mode, the air intake cover can rotate relative to the air intake pipe and cut off the pipeline of the air intake pipe to prevent water from flowing through the air intake pipe into the air conditioning box. In normal mode, the air intake cover is rotated to the open state, the air intake channel of the air intake pipe is opened, and the air conditioning external circulation pipeline can be used normally. At the same time, the space required for the air intake cover to rotate open and cut off the air intake pipe is small, which can optimize the spatial layout of the air intake pipe assembly of the present application. Furthermore, the present application realizes automatic control of the opening and closing of the air intake cover through a motor. The use of a motor-driven method is not only simple and compact in structure, but also low in cost.

[0009] It can be understood that the present application sets an air inlet cover to reliably block the infiltration of water, and at the same time rotatably connects the air inlet cover to the air inlet pipe, thereby optimizing the spatial layout of the air inlet pipe assembly and reducing the space occupied by the air inlet pipe assembly. In addition, a motor is used to automatically control the opening and closing of the air inlet cover, which has a simple structure and low cost.

[0010] In one embodiment, the air inlet cover has a rotating shaft, and the motor is used to drive the rotating shaft to rotate.

[0011] In one embodiment, the air inlet cover is received in the air inlet pipe.

[0012] In this embodiment, the air inlet cover is arranged in the air inlet pipe, which can ensure that the air inlet cover can reliably block water from penetrating into the air conditioner, while also making the air inlet pipe assembly structure compact and optimizing the space layout.

[0013] In one embodiment, the motor is arranged outside the air intake pipe, a through hole is arranged on the air intake pipe, and the rotating shaft is transmission-connected to the motor via the through hole.

[0014] In this embodiment, since the motor is located outside the air intake pipe, a through hole is opened in the air intake pipe so that the motor and the rotating shaft can be connected through the through hole, ensuring that the motor can drive the air intake cover to rotate to open or block the air intake pipe.

[0015] In one embodiment, a sealing ring is provided between the through hole and the rotating shaft or the motor shaft of the motor, and the sealing ring is used to seal the through hole.

[0016] In this embodiment, a sealing ring is provided between the through hole and the rotating shaft or the motor shaft of the motor to seal the through hole, thereby preventing water from flowing into the interior of the vehicle from the through hole and preventing outside air from flowing out of the through hole to affect the air intake efficiency of the air conditioner.

[0017] In one embodiment, the axis of the rotating shaft deviates from the geometric center of the cross section of the intake pipe.

[0018] In this embodiment, by setting the axis of the rotating shaft to deviate from the geometric center of the cross section of the intake pipe, that is, by eccentrically setting the intake pipe and the rotating shaft, the impact on the intake efficiency of the intake pipe can be reduced when the air intake cover is opened.

[0019] In one embodiment, the radial cross-section of the air intake pipe is similar to a square, and the air intake pipe includes a bottom wall and a side wall connected to each other, the rotating shaft is arranged on the bottom wall, and the through hole is arranged on the side wall.

[0020] In this embodiment, by setting the radial cross section of the intake pipe to be square, it can be ensured that the rotating shaft can be rotatably connected to the inside of the intake pipe, while improving the intake efficiency.

[0021] In one embodiment, a protrusion is provided on the inner wall of the air inlet pipe, and the protrusion is used to limit the rotation angle of the air inlet cover.

[0022] In this embodiment, a protrusion is provided on the inner wall of the air inlet pipe to block the rotation of the air inlet cover, thereby limiting the rotation angle of the air inlet cover and preventing the air inlet cover from being opened when the water flow in the air inlet pipe is too large.

[0023] In one embodiment, the air intake duct has a first side surface facing the vehicle body, and the air intake duct also has a second side surface and a third side surface arranged opposite to each other, and the second side surface and the third side surface are suitable for intersecting with the first side surface; the inner wall of the air intake duct is provided with an air guide plate, and the air guide plate is arranged on the second side surface, and in the direction from the second side surface to the third side surface, the air guide plate extends obliquely away from the first side surface.

[0024] In this embodiment, an air guide plate is provided on the second side surface of the air intake pipe, and is extended obliquely in the direction from the second side surface to the third side surface in a direction away from the first side surface. On the one hand, the air guide plate can prevent the air intake cover from generating large resistance when the air is introduced, and at the same time prevent the air flow from entering the bottom of the air intake cover and the gap around the rotating shaft to generate a whistling sound; on the other hand, the air guide plate can guide the air to flow toward the air-conditioning box, thereby improving the air intake efficiency.

[0025] In one embodiment, the air guide plate is arranged on the side of the air inlet cover away from the air conditioning box body. When the air inlet cover rotates to the second side surface, along the air inlet path, the length of the air inlet cover is smaller than the distance between the air guide plate and the rotation axis.

[0026] In one embodiment, a water hole is formed between the air guide plate and the second side surface.

[0027] In this embodiment, by providing water holes on the air guide plate and the second side surface, the accumulated water remaining between the air guide plate and the air inlet cover can flow out smoothly.

[0028] In one embodiment, the first side surface has an opening connected to the vehicle body, and the edge of the opening is arranged on the sealing ring.

[0029] In one embodiment, a sealing buffer is provided on the air inlet cover. When the air inlet cover blocks the air inlet pipe, the sealing buffer abuts against the inner wall of the air inlet pipe and deforms.

[0030] In this embodiment, by providing a sealing buffer on the air inlet cover, on the one hand, the sealing buffer can play a buffering role when closing the air inlet cover to reduce noise; on the other hand, the sealing buffer can play a sealing role to improve the waterproof sealing performance.

[0031] In one embodiment, when the air inlet cover opens the air inlet pipe, a buffer pad is provided on a side of the air inlet cover facing the second side surface.

[0032] In this embodiment, the buffer pad can play a role in buffering and reducing noise during the opening process of the air intake cover.

[0033] In one embodiment, the sealing buffer is made of sponge or rubber material.

[0034] In one embodiment, the buffer pad is made of sponge or rubber material.

[0035] In one embodiment, there are two motors, which are arranged on opposite sides of the rotating shaft along the axial direction of the rotating shaft, and each motor is drivingly connected to one end of the rotating shaft.

[0036] In this embodiment, by arranging a motor on two opposite sides of the rotating shaft respectively, the two motors jointly drive the rotating shaft to rotate, thereby improving the synchronization of the two opposite sides of the rotating shaft and improving the sealing performance of the air inlet cover.

[0037] In one embodiment, when the air inlet cover blocks the air inlet pipe, a convex rib is provided on the end surface of the air inlet cover facing away from the air conditioning box, and the convex rib is used to improve the strength of the air inlet cover.

[0038] In this embodiment, convex ribs are provided on the end surface of the air inlet cover facing away from the air conditioner housing to increase the strength of the air inlet cover and improve the reliability of the air inlet cover.

[0039] In a second aspect, the present application provides a vehicle, comprising an air-conditioning box, a vehicle body and an air intake duct assembly as in any of the above embodiments, wherein the air intake duct assembly is arranged between the air-conditioning box and the vehicle body, and connects the air-conditioning box to the outside.

[0040] It can be understood that the vehicle provided in the second aspect of the present application, because it adopts the intake pipe assembly provided in the first aspect of the present application, also has all possible beneficial effects in any embodiment provided in the first aspect of the present application.

[0054] For details, see Figure 1 and Figure 2 ,in Figure 1 A schematic diagram of a portion of the structure of a vehicle provided in one embodiment of the present application; Figure 2 A partial schematic diagram of a vehicle body 200 provided in an embodiment of the present application; Figure 3 It is a structural schematic diagram of an air conditioning cabinet assembly 300 provided in one embodiment of the present application.

[0055] like Figures 1 to 3As shown, the vehicle of the present application includes an air conditioning box assembly 300, a car body 200 and an air intake pipe assembly 100. The car body 200 shown in the figure is a front panel 201 in the lower cross beam assembly of the front windshield, and an air conditioning air inlet 202 is provided on the front panel 201. In another embodiment, the car body 200 may be other positions of the vehicle, and the present application does not specifically limit this). The air conditioning box assembly 300 includes a blower housing 301 and an air conditioning box 302 that are interconnected. The air intake pipe assembly 100 is arranged between the front panel 201 and the air conditioning box 302. Specifically, it is connected between the air conditioning air inlet and the blower housing 301. The vehicle provided in the present application includes a normal mode, a wading mode and a floating mode. A water level sensor (not shown in the figure) is provided at the position of the rearview mirror of the vehicle to detect the water level outside the vehicle. When the vehicle enters a flooded road surface or a deep water location such as a river or pit, the water level sensor automatically detects the water level. When the water level exceeds the set threshold, the wading mode is automatically turned on. The threshold is designed to match the vehicle in advance and is usually set to the height of the bottom of the air-conditioning inlet 202 minus 150mm. When the vehicle continues to drive into deeper waters and the four wheels are completely off the ground, the vehicle enters the floating mode. When the vehicle is driving on a normal road, the vehicle enters the normal mode.

[0056] Please see Figure 4 and Figure 5 ,in Figure 4 This is a structural schematic diagram of an intake pipe assembly 100 provided in one embodiment of the present application; Figure 5 It is a schematic diagram of the cross-sectional structure of an intake pipe assembly 100 provided in an embodiment of the present application.

[0057] like Figures 1 to 5 As shown, in one embodiment, the present application provides an air intake pipe assembly 100, which is arranged between the air conditioning box 302 and the front panel 201 of the vehicle. The air intake pipe assembly 100 includes an air intake pipe 10, an air intake cover 20 and a motor 30. The air intake pipe 10 connects the air conditioning box 302 with the outside. Specifically, the air intake pipe 10 is connected between the air conditioning air inlet 202 and the blower housing 301. The air intake cover 20 is rotatably connected to the air intake pipe 10, that is, the air intake cover 20 is connected to the air intake pipe 10, and can also rotate relative to the air intake pipe 10. The motor 30 is used to drive the rotating shaft 21 to rotate and drive the air intake cover 20 to rotate relative to the air intake pipe 10 to open or block the pipeline of the air intake pipe 10.

[0058] In one embodiment, the extending direction of the rotating shaft 21 of the air inlet cover 20 is perpendicular to the air intake path direction of the air intake pipe 10. The motor 30 is disposed outside the air intake pipe 10 and is in transmission connection with the rotating shaft 21.

[0059] It can be understood that the air intake pipe assembly 100 of the present application is connected to the air intake pipe 10 by rotating the air intake cover 20, so that when the vehicle is in the wading mode or the floating mode, the air intake cover 20 can rotate relative to the air intake pipe 10 and cut off the pipeline of the air intake pipe 10 to prevent water from flowing into the air conditioning box 302 through the air intake pipe 10. In the normal mode, the air intake cover 20 is rotated to the open state, the air intake channel of the air intake pipe 10 is opened, and the air conditioning external circulation pipeline can be used normally. At the same time, the present application also sets the extension direction of the rotating shaft 21 to be perpendicular to the air intake path direction of the air intake pipe 10, and the space required for the air intake cover 20 to rotate and open and cut off the air intake pipe 10 is small, which can optimize the spatial layout of the air intake pipe assembly 100 of the present application. Further, the present application also sets a motor 30 to be transmission-connected with the rotating shaft 21 of the air intake cover 20, so as to use the motor 30 to realize automatic control of the opening and closing of the air intake cover 20. The driving method using the motor 30 is not only simple and compact in structure but also low in cost.

[0060] That is, the present application sets an air inlet cover 20 to reliably block the infiltration of water, and at the same time rotatably connects the air inlet cover 20 to the air inlet pipe 10, thereby optimizing the spatial layout of the air inlet pipe 10 assembly and reducing the space occupied by the air inlet pipe 10 assembly. In addition, the motor 30 is used to automatically control the opening and closing of the air inlet cover 20, which has a simple structure and low cost.

[0061] exist Figure 4 and Figure 5 In the embodiment shown, the air inlet cover 20 is received in the air inlet pipe 10, that is, the air inlet cover 20 is arranged inside the air inlet pipe 10. The air inlet pipe 10 is provided with a through hole (not shown in the figure), and the motor shaft of the motor 30 passes through the through hole and is transmission-connected with the rotating shaft 21.

[0062] It can be understood that in this embodiment, the air inlet cover 20 is arranged in the air inlet pipe 10, and while ensuring that the air inlet cover 20 can be rotated to open or close relative to the air inlet pipe 10, it can also ensure that the air inlet cover 20 can reliably block water from penetrating into the air conditioner in the closed state, and in addition, it can make the assembly structure of the air inlet pipe 10 compact, reduce the occupied volume, and optimize the space layout. Further, by opening a through hole on the air inlet pipe 10, the motor 30 and the rotating shaft 21 can be connected through the through hole, ensuring that the motor 30 can drive the air inlet cover 20 to rotate to open or block the pipeline of the air inlet pipe 10.

[0063] It should be noted that, in another embodiment, the motor shaft does not extend into the air intake pipe 10, and the rotating shaft 21 may pass through the through hole and be connected to the external motor 30 shaft, which may also have the same beneficial effect.

[0064] Furthermore, in one embodiment, the motor shaft and the rotating shaft 21 are connected by a spline (not shown). This connection method has a simple structure and reliable connection. When the motor shaft of the motor 30 rotates, the rotating shaft 21 is driven to rotate to open or close the air inlet cover 20, that is, to open or block the pipeline of the air inlet pipe 10.

[0065] It should be noted that the connection relationship between the motor shaft and the rotating shaft 21 in the above embodiment is only used as an exemplary introduction, that is, the connection relationship between the motor shaft and the rotating shaft 21 in the present application is not limited to splines.

[0066] In one embodiment, the motor shaft extends into the intake pipe 10 and is connected to the rotating shaft 21, and a sealing ring (not shown in the figure) is provided between the through hole and the motor shaft of the motor 30, and the sealing ring is used to seal the gap between the through hole and the motor shaft of the motor 30.

[0067] It can be understood that in this embodiment, a sealing ring is provided between the through hole and the rotating shaft 21 or the motor 30 shaft of the motor 30 to seal the through hole, thereby preventing water from flowing into the interior of the vehicle from the through hole. At the same time, it can also prevent outside air from flowing out of the through hole when the air conditioner is in the external circulation mode, thereby affecting the air intake efficiency of the air conditioner.

[0068] In one embodiment, the axis of the rotating shaft 21 deviates from the geometric center of the cross section of the intake pipe 10. It can be understood that in this embodiment, by setting the axis of the rotating shaft 21 to deviate from the geometric center of the cross section of the intake pipe 10, that is, by eccentrically setting the intake pipe 10 and the rotating shaft 21, the influence on the intake efficiency of the intake pipe 10 can be reduced when the air inlet cover 20 is opened.

[0069] exist Figure 4 and Figure 5 In the illustrated embodiment, the radial cross section of the air intake pipe 10 is similar to a square, and the air intake pipe 10 includes a bottom wall 11, two side walls 12 and a top wall 13, wherein the bottom wall 11 is arranged opposite to the top wall 13, and the two side walls 12 connect the bottom wall 11 and the top wall 13. The bottom wall 11, the two side walls 12 and the top wall 13 are jointly arranged to form an air intake channel. In addition, the air intake pipe 10 is a reducer, that is, along the air intake path of the air intake pipe 10, the air intake pipe 10 includes a connected large diameter section 14 and a small diameter section 15. The large diameter section 14 is closer to the air inlet 202 of the air conditioner than the small diameter section 15. The air inlet cover 20 is arranged on the large diameter section 14, and the rotating shaft 21 is arranged on the bottom wall 11 of the large diameter section 14, and the through hole is arranged on the side wall 12 of the large diameter section 14.

[0070] It can be understood that in the present embodiment, by setting the radial cross-section of the air intake pipe 10 to be square, it can be ensured that the rotating shaft 21 can be rotatably connected to the inside of the air intake pipe 10, while improving the air intake efficiency. Furthermore, the air intake pipe 10 is set as a reducer, and the large diameter section 14 is relatively close to the air inlet 202 of the air conditioner, and the air intake cover 20 is set at the large diameter section 14, which can further improve the air intake efficiency. For example, when the air conditioner is in the external circulation mode, the motor 30 drives the air intake cover 20 to open and fit against the bottom wall 11 of the large diameter section 14 of the air intake pipe 10, and the outside air can smoothly and quickly enter the air conditioning box 302; and when the air conditioner is not in the external circulation mode, the motor 30 drives the air intake cover 20 to close, and the end of the air intake cover 20 away from the rotating shaft 21 fits against the top wall 13 of the air intake pipe 10, the pipeline of the air intake pipe 10 is blocked, and the air conditioner can only be turned off or switched to the internal circulation mode. (Please refer to Figure 6 As shown, Figure 6 This is a schematic diagram of the cross-sectional structure of an intake pipe assembly 100 provided in another embodiment of the present application. It should be noted that: Figure 5 is a schematic diagram of the air inlet cover 20 in an open state, Figure 6 Schematic diagram of the air inlet cover 20 in a closed state.

[0071] In one embodiment, the inner wall of the air inlet pipe 10 is provided with a protrusion 16, and the protrusion 16 is used to limit the rotation angle of the air inlet cover 20. It can be understood that in this embodiment, by providing the protrusion 16 on the inner wall of the air inlet pipe 10 to block the rotation of the air inlet cover 20, the rotation angle of the air inlet cover 20 is limited, and at the same time, the air inlet cover 20 can be prevented from being opened when the water flow in the air inlet pipe 10 is too large.

[0072] In one embodiment, the air intake duct 10 has a first side surface 17 facing the vehicle body 200, and the air intake duct 10 also has a second side surface 18 and a third side surface 19 arranged opposite to each other, and the second side surface 18 and the third side surface 19 are suitable for intersecting with the first side surface 17. An air guide plate 40 is provided on the second side surface 18, and the air guide plate 40 is located on the side of the air intake cover 20 away from the air conditioning box 302, and the air guide plate 40 extends obliquely in the direction from the second side surface 18 to the third side surface 19, toward the direction away from the first side surface 17.

[0073] It can be understood that in this embodiment, along the air intake path, the air guide plate 40 is inclined and extends in the direction from the second side surface 18 to the third side surface 19, away from the first side surface 17. On the one hand, the air guide plate 40 can prevent the air inlet cover 20 from generating a large resistance when the air is entering, and at the same time prevent the air flow from entering the bottom of the air inlet cover 20 and the gap around the rotating shaft 21 to generate a whistling sound; on the other hand, the air guide plate 40 can guide the air to flow toward the air-conditioning box 302, thereby improving the air intake efficiency.

[0074] In one embodiment, the air guide plate 40 is disposed on the side of the air inlet cover 20 away from the air conditioning box 302. When the air inlet cover 20 rotates to the second side surface 18, along the air inlet path, the length of the air inlet cover 20 is smaller than the distance between the air guide plate 40 and the rotating shaft 21, that is, when the air inlet cover 20 is fully opened, the air guide plate 40 is spaced apart from the air inlet cover 20. It can be understood that limiting the position of the air guide plate 40 to the above position can ensure that the air guide plate 40 can guide the airflow while also ensuring that the air guide plate 40 does not interfere with the movement of the air inlet cover 20.

[0075] Please look back Figure 4 In one embodiment, a water hole 41 is formed between the air guide plate 40 and the second side surface 18. In this embodiment, by providing the water hole 41 between the air guide plate 40 and the second side surface 18, the accumulated water left between the air guide plate 40 and the air inlet cover 20 can flow out smoothly.

[0076] In one embodiment, a sealing buffer 50 is disposed on the air inlet cover 20 . When the air inlet cover 20 blocks the air inlet pipe 10 , the sealing buffer 50 abuts against the inner wall of the air inlet pipe 10 and deforms.

[0077] In this embodiment, by providing a sealing buffer 50 on the air inlet cover 20, on the one hand, the sealing buffer 50 can play a buffering role when the air inlet cover 20 is rotated and closed to reduce noise; on the other hand, the sealing buffer 50 can play a sealing role to improve the waterproof sealing performance.

[0078] In one embodiment, when the air inlet cover 20 fully opens the air inlet pipe 10, a buffer pad 60 is provided on the side of the air inlet cover 20 facing the second side surface 18. In this embodiment, the buffer pad 60 can play a role in buffering and reducing noise when the air inlet cover 20 is rotated to fully open.

[0079] In one embodiment, the sealing buffer 50 is made of sponge or rubber material.

[0080] In one embodiment, the buffer pad 60 is made of sponge or rubber material.

[0081] In one embodiment, there are two motors 30, which are a left opening and closing motor 31 and a right opening and closing motor 32. The left opening and closing motor 31 and the right opening and closing motor 32 are arranged on opposite sides of the rotating shaft 21 along the axial direction of the rotating shaft 21, and each motor 30 is transmission-connected to one end of the rotating shaft 21. The left opening and closing motor 31 and the right opening and closing motor 32 are both arranged outside the air inlet duct, and the two motors 30 are connected by a wire.

[0082] In this embodiment, a motor 30 is provided on the opposite sides of the rotating shaft 21, and the two motors 30 are connected by a wire. The two motors 30 rotate forward or reverse synchronously and jointly drive the rotating shaft 21 to rotate. This can improve the synchronization of the opposite sides of the rotating shaft 21, avoid shaking and jamming of the rotating shaft 21, and thus improve the sealing performance of the air inlet cover 20.

[0083] In one embodiment, the motor 30 is fixed to the outside of the intake pipe 10 by screws.

[0084] exist Figure 6 In the illustrated embodiment, when the air inlet cover 20 blocks the air inlet pipe 10, the end surface of the air inlet cover 20 facing away from the air conditioning box 302 is provided with a convex rib 22, and the convex rib 22 is used to improve the strength of the air inlet cover 20. In this embodiment, by providing the convex rib 22 on the air inlet cover 20, the strength of the air inlet cover 20 can be increased, and the reliability of the air inlet cover 20 can be improved. At the same time, the convex rib 22 is provided on the end surface of the air inlet cover 20 facing away from the air conditioning box 302 in the closed state, which can ensure that the end surface of the air inlet cover 20 facing the air conditioning box 302 is relatively smooth, so as to improve the air intake efficiency when the air inlet cover 20 is in the open state.

[0085] In one embodiment, the first side surface 17 has an opening 171 connected to the vehicle body 200, and a sealing ring 70 is provided at the edge of the opening, that is, a sealing ring 70 is provided at one end of the air intake pipe 10 facing the air inlet 202 of the air conditioner. The sealing ring 70 is used to seal the gap between the air intake pipe 10 and the vehicle body 200.

[0086] In one embodiment, a first sealing sponge 80 is adhered to one end of the air intake pipe 10 facing the air conditioning box 302. The first sealing sponge 80 is used to seal the gap between the air intake pipe 10 and the air conditioning box 302.

[0087] In one embodiment, a second sealing sponge 90 is adhered to one end of the blower housing 301 facing the air intake pipe 10. The first sealing sponge 80 and the second sealing sponge 90 cooperate with each other to achieve multi-stage sealing, thereby providing sealing of the air intake passage.

[0088] In one embodiment, the air inlet cover 20 is set to be normally open. When the vehicle enters a deep water area, the vehicle turns on the wading mode or the floating mode according to the water level, and the vehicle controls the air inlet cover 20 to close to prevent water from entering the vehicle from the air-conditioning air inlet. At the same time, the automobile air-conditioning is associated with the whole vehicle driving mode. When the vehicle enters the wading mode or the floating mode, the air inlet cover 20 is closed. If the air-conditioning is in the external circulation mode, it can automatically switch to the internal circulation mode. Therefore, even if the air-conditioning air inlet 202 of the vehicle is submerged below the water surface, the air-conditioning can be used normally.

[0089] It can be understood that the air inlet cover 20 in the air intake pipe assembly 100 of the present application can automatically control the opening and closing state with the motor 30, and has excellent waterproof performance, which can meet the needs of the vehicle wading at a depth of more than 1 meter and floating on water; at the same time, the modified structure is compact in design and easy to assemble and operate, and does not affect the air intake of the air conditioner at all.
