The exhaust duct 1 extends in the thickness direction of the vehicle, is provided on an exhaust gas discharge device of the vehicle, and an exhaust port 13 is provided at the top of the exhaust duct 1, and exhaust gas discharged from the vehicle is discharged from the exhaust port 13 via the exhaust duct 1. The detector 2 is used for detecting the water level at the position of the vehicle, the driving component 3 is connected to the exhaust pipeline 1 and is electrically connected to the detector 2, so that the detector 2 transmits information about whether the detected water level at the position of the vehicle is higher than or equal to a first preset height to the driving component 3, when the water level detected by the detector 2 is higher than or equal to the first preset height, the driving component 3 drives at least part of the exhaust pipeline 1 to move along the thickness direction of the vehicle, so that the height of the exhaust port 13 along the thickness direction of the vehicle is greater than a second preset height, and the second preset height is greater than the first preset height, and it can be understood that when the water level reaches the first preset height, the detector 2 transmits a signal to the driving component 3, and the driving component 3 drives the exhaust port 13 to move along the thickness direction of the vehicle, so that the height of the exhaust port 13 is greater than the second preset height, and is greater than the first preset height, so that the exhaust port 13 can exceed the water level, and the vehicle can safely pass through the water-through road section. The wading tail pipe 100 can spontaneously adjust the self-height through the detection of the detector 2 and the driving of the driving component 3, so that the exhaust port 13 is higher than the water surface, the vehicle can safely run, the tail pipe is prevented from being manually replaced, and the use convenience is improved.

Referring to fig. 5 and 6, the first exhaust pipe 11 has an initial position and a first position, the driving assembly 3 is disposed on the second exhaust pipe 12 and is connected to the first exhaust pipe 11, that is, the driving assembly 3 is connected between the first exhaust pipe 11 and the second exhaust pipe 12, so as to drive the first exhaust pipe 11 to move from the initial position to the first position in the thickness direction of the vehicle, and when the first exhaust pipe 11 is in the first position, the height of the exhaust port 13 in the thickness direction of the vehicle is greater than the second preset height. It will be appreciated that when the vehicle passes through the wading section, the driving assembly 3 drives the first exhaust pipe 11 to move relative to the second exhaust pipe 12 from the initial position to the first position, so that the height of the exhaust port 13 in the thickness direction of the vehicle is greater than the second preset height, i.e. higher than the water surface height, so that the exhaust port 13 is exhausted normally, and the vehicle passes through the wading section safely.

In some embodiments, the driving assembly 3 can drive the first exhaust pipe 11 to move to the initial position when the water level detected by the detector 2 is lower than the first preset height. When the vehicle enters the non-wading road section from the wading road section, the detector 2 detects that the water level is lower than the first preset height, and then the driving assembly 3 drives the first exhaust pipe 11 to move to the initial position according to the detection result of the detector 2, so that the normal running of the vehicle is ensured, and when the first exhaust pipe 11 moves to the initial position, the area sleeved on the second exhaust pipe 12 is increased, so that the volume of the wading tail pipe 100 is relatively reduced, and the air resistance of the vehicle in running is reduced.

In some embodiments, the driving assembly 3 includes a cylinder 31 connected between the first exhaust pipe 11 and the second exhaust pipe 12, where the cylinder 31 is configured to provide driving force for the movement of the second exhaust pipe 12 relative to the first exhaust pipe 11, and it is understood that a push rod and a cylinder body of the cylinder 31 are respectively connected to the first exhaust pipe 11 and the second exhaust pipe 12, and air is introduced into the cylinder body of the cylinder 31, so as to push the push rod of the cylinder 31 to move relative to the cylinder body in the vehicle thickness direction, so as to drive the first exhaust pipe 11 to move relative to the second exhaust pipe 12. The driving assembly 3 further comprises an electromagnetic valve 32 which is respectively communicated with the air source and the air inlet of the air cylinder 31, wherein the air inlet is communicated with the body of the air cylinder 31, and the air source is communicated with the air inlet through an air channel 4 through the electromagnetic valve 32. The electromagnetic valve 32 is also electrically connected to the detector 2 and is configured to be in an open state when the water level detected by the detector 2 is higher than or equal to a first preset level, and after the electromagnetic valve 32 is opened, gas in the gas source smoothly enters the cylinder body of the cylinder 31 through the gas inlet, and the push rod of the cylinder 31 is pushed to move, so that the first exhaust pipe 11 is driven to move relative to the second exhaust pipe 12.

In some embodiments, the solenoid valve 32 is configured to be able to be in a closed state when the level of water detected by the detector 2 is below a first preset level. When the vehicle enters the non-wading section from the wading section, the detector 2 detects that the water level is lower than the first preset level, and at this time, the solenoid valve 32 is in a closed state, and the gas in the gas source cannot enter the cylinder 31, so that the cylinder 31 is disconnected. In some embodiments, a return spring is provided between the push rod of the cylinder 31 and the cylinder body, and when the cylinder 31 is out of air and no air source is input, the return spring drives the push rod of the cylinder 31 to return, thereby driving the first exhaust pipe 11 to be in the initial position.

In some embodiments, the air introduced into the cylinder 31 may be compressed air, the compressed air is introduced into the cylinder body to provide a driving force for the movement of the push rod of the cylinder 31, and the restoring spring is in a stretched state, the driving force needs to overcome the elastic force of the restoring spring, so that the push rod of the cylinder 31 is driven to drive the first exhaust pipe 11 to move, when the electromagnetic valve 32 is closed, the compressed air is not introduced into the cylinder 31 any more, and the restoring spring in the stretched state provides an elastic force for the push rod of the cylinder 31 in the thickness direction of the vehicle, so as to drive the first exhaust pipe 11 to move in the thickness direction of the vehicle, and make the first exhaust pipe 11 in an initial state.

In some embodiments, the push rod of the cylinder 31 is connected with the first exhaust pipe 11 through a bolt, a connecting hole is arranged at one end of the push rod of the cylinder 31 away from the cylinder body, a through hole corresponding to the connecting hole is arranged on the side wall of the first exhaust pipe 11, and the bolt passes through the through hole and the connecting hole to connect the first exhaust pipe 11 with the push rod of the cylinder 31. In some embodiments, a gasket 15 is disposed at a connection portion between the push rod of the cylinder 31 and the first exhaust pipe 11, and the gasket 15 is configured to improve the connection strength between the push rod of the cylinder 31 and the first exhaust pipe 11, and avoid damage to the side wall of the first exhaust pipe 11 when the push rod pushes the first exhaust pipe 11.

In some embodiments, the through hole on the side wall of the first exhaust pipe 11 is configured such that a protruding portion is provided on the side wall of the first exhaust pipe 11, and the through hole is penetrated on the protruding portion, so that the side wall of the first exhaust pipe 11 is prevented from being directly penetrated to perform perforation, thereby improving the rigidity of the first exhaust pipe 11 and prolonging the service life thereof.

In some embodiments, the first exhaust pipe 11 includes a channel extending along a longitudinal direction of the pipe body, the exhaust pipe 1 further includes a plurality of locking members 14 disposed on the second exhaust pipe 12 and corresponding to the channel, and when the first exhaust pipe 11 is in the first position, the locking members 14 lock the first exhaust pipe 11 and the second exhaust pipe 12 through the channel, it can be understood that when the first exhaust pipe 11 moves in a vehicle thickness direction relative to the second exhaust pipe 12, the locking members 14 move relatively along the channel, so as to guide the movement of the first exhaust pipe 11, ensure accuracy of the movement direction of the first exhaust pipe 11, and strengthen connection strength between the first exhaust pipe 11 and the second exhaust pipe 12.

The water level push rod 23 is configured to be able to drive the connection pin 22 so that the connection pin 22 and the interface 24 are in contact with each other when the water level height at the position where the vehicle is located is higher than or equal to a first preset height, and the wading tail pipe 100 further includes a power source having one end electrically connected to the connection pin 22 and the other end electrically connected to the solenoid valve 32 and the interface 24.

The bottom of the body 21 is provided with a water inlet 25 communicating with the accommodation chamber 211, and when the water level at the position where the vehicle is located is higher than or equal to a first preset height, the liquid flowing into the accommodation chamber 211 through the water inlet 25 can drive the piston portion 231 and the rod body portion 232 of the water level push rod 23 to move in the axial direction of the accommodation chamber 211 so that the connection pin 22 and the interface member 24 are brought into contact with each other. When the height of the water level at the position where the vehicle is located is lower than the first preset height, the liquid in the accommodating chamber 211 flows out through the water inlet 25, the piston portion 231 and the rod body portion 232 of the water level push rod 23 move in the axial direction of the accommodating chamber 211 under the gravity action of the water level push rod 23, that is, move downward in the thickness direction of the vehicle under the gravity action back to the original position, which is a position not moved upward by the liquid flowing into the accommodating chamber 211, thereby disconnecting the connection pin 22 from the interface 24 and returning the first exhaust pipe 11 to the original position.

In some embodiments, when the detector 2 is mounted on the chassis of the vehicle, the detector 2 is made to be close to the front of the vehicle relative to the wading tail pipe 100, and the water inlet 25 of the detector 2 is made to face the advancing direction of the vehicle, so that when the vehicle enters the wading section, the detector 2 can timely detect whether the water level reaches the first preset height, and therefore the first exhaust pipe 11 is timely adjusted to be in the first position, and safe running of the vehicle on the wading section is ensured.
