Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an exhaust assembly, an exhaust system and a vehicle. Background Art

[0002] The function of a car's vents is to release air when the car door is closed, thereby balancing the air pressure inside and outside the car. When a car is wading through water, existing motor-driven vent blades remain open, allowing unimpeded access between the vehicle's interior and exterior. This can easily lead to water or dust entering the vehicle, causing water or dust to enter the cabin, potentially damaging electronic equipment, and potentially harming the vehicle's safety. Summary of the Invention

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0053] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0054] When a car door is closed, the interior space is sealed off. Due to the squeezing effect of the door, the volume of the air inside the car decreases and the pressure increases. To balance the air pressure inside and outside the car and avoid problems such as difficulty closing the door, air resistance, and pressure on the windows and body structure, some air inside the car needs to be discharged through the exhaust vent. When the pressure inside the car is higher than that outside, the air will flow out of the exhaust vent due to the pressure difference until the pressure inside and outside is roughly equal. The air can then be discharged through the exhaust vent, relieving pressure and promoting air circulation.

[0055] Reference below Figures 1-12 An exhaust assembly 100 , an air intake system, and a vehicle 200 according to an embodiment of the present invention are described.

[0056] refer to Figure 2-Figure 6 According to a first aspect of the present invention, an exhaust assembly 100 is provided. The exhaust port assembly is suitable for being provided at an exhaust port of a vehicle 200. The exhaust port assembly includes:

[0057] The ventilation blades 101 are configured to open when subjected to external force to achieve ventilation of the vehicle 200;

[0058] The cover plate 102 can selectively cover the exhaust port.

[0059] Through the dual protection of the ventilation blades 101 and the cover plate 102, while ensuring normal ventilation of the vehicle 200, water, dust and other impurities are prevented from entering the vehicle, thereby improving the safety of the vehicle 200 and the comfort of the riding environment.

[0060] Specifically, if the ventilation blades 101 are driven by a motor and are always open, external impurities such as water or dust will enter the vehicle, causing safety hazards and other problems. Therefore, the present invention is provided with ventilation blades 101, which can be opened when subjected to external force, thereby realizing ventilation of the vehicle 200. The external force may be the pressure inside the vehicle or the suction outside the vehicle. The external force may be a passive force or an active force such as a motor, which is not limited here. When the external force is a passive force, such as when the pressure inside the vehicle is greater than the external pressure, the ventilation blades 101 are pushed open from inside the vehicle to outside the vehicle to achieve passive ventilation; at the same time, there are situations where the pressure inside the vehicle is less than the external pressure, such as when wading or in strong winds, which will cause the ventilation blades 101 to be opened from outside the vehicle to inside the vehicle, resulting in passive ingress of water or impurities such as dust, affecting the safety of the vehicle 200 or the comfort of the riding environment. Therefore, the present invention is also provided with a cover 102, which can selectively cover the exhaust port. When the ventilation blades 101 are passively ventilated, the cover 102 does not cover the exhaust port, so that the vehicle 200 can be exhausted normally; when the vehicle 200 has no exhaust demand, the cover 102 covers the exhaust port, making the exhaust port relatively closed, and external impurities cannot enter the vehicle, thereby ensuring the safety of the vehicle 200 or the comfort of the riding environment.

[0061] In some embodiments, the ventilation blades 101 can be made of a flexible material, such as butyl rubber, silicone rubber, or thermoplastic elastomer (TPE), exhibiting good elasticity and flexibility, providing excellent sealing performance and a long service life. The ventilation blades 101 can be partially fixed to the exhaust port or can rotate relative to the exhaust port. When the pressure inside the vehicle is greater than the external pressure, the ventilation blades 101 are actuated by the airflow to open the exhaust port. Gravity then causes the ventilation blades 101 to sag downward, closing the exhaust port and achieving exhaust of the vehicle 200.

[0062] In some embodiments, as Figure 3-6 As shown, the exhaust assembly 100 also includes a bracket 103, which is arranged at the exhaust port. The ventilation blade 101 is rotatably arranged on the bracket 103. The ventilation blade 101 has a first end and a second end opposite to each other along its length direction. The first end and the second end are both rotatably connected to the bracket 103.

[0063] Specifically, bracket 103 is provided at the exhaust port, and the connection method can be snap-fitting, screwing, bonding, or other conventional connection methods in the art, which are not limited here. The ventilation blade 101 has a first end and a second end along its length, both of which are rotatably connected to bracket 103. The connection between the ventilation blade 101 and bracket 103 can be achieved using conventional methods such as snap-fitting. Bracket 103 provides a mounting position for the ventilation blade 101, allowing it to be stably fixed to the exhaust port, preventing the ventilation blade 101 from falling or other problems.

[0064] In some embodiments, a plurality of ventilation blades 101 are arranged on a bracket 103 along a first direction. When the exhaust assembly 100 is installed on a vehicle 200, the first direction is the height direction of the vehicle 200. The ventilation blades 101 have opposing third and fourth ends along their width. The plurality of ventilation blades 101 are arranged on the bracket 103 along the first direction, and the fourth end of each ventilation blade 101 overlaps the bracket 103.

[0065] Specifically, the third end is fixed relative to bracket 103 and can only rotate in place, while the fourth end is free. When the exhaust port is not in use, the fourth end, influenced by its own gravity, overlaps bracket 103, sealing the exhaust port. When the exhaust port is in use, the fourth end, influenced by the pressure inside the vehicle, moves away from bracket 103, opening the exhaust port for exhaust. The present invention provides multiple ventilation blades 101, which can prevent problems such as damage or jamming of a single ventilation blade 101, which could lead to poor exhaust in vehicle 200, thereby achieving smoother exhaust.

[0066] In other embodiments, multiple ventilation blades 101 are arranged on the bracket 103 along a second direction. When the exhaust assembly 100 is installed on the vehicle 200, the second direction is a direction intersecting the height direction of the vehicle 200. The present invention is not limited to the arrangement direction of the ventilation blades 101 on the bracket 103. Most preferably, they are arranged along the height direction of the vehicle 200. This arrangement allows the ventilation blades 101 to be more stably installed on the bracket 103 and, due to their own gravity, achieve the best sealing effect on the exhaust port.

[0067] In some embodiments, as Figure 12 As shown, relative to the vehicle 200 , the cover plate 102 is adapted to be disposed on a side of the ventilation blade that is away from the vehicle 200 .

[0068] Specifically, the ventilation blades 101 are positioned within the notch formed by the exhaust port, and the cover plate 102 is positioned on the outside of the ventilation blades 101 relative to the vehicle 200. Because the ventilation blades 101 are made of flexible material, they are susceptible to external forces, causing deformation or opening toward the vehicle interior, which could lead to water ingress. Therefore, the present invention positions the cover plate 102 on the outside of the ventilation blades 101 relative to the vehicle 200. This prevents foreign matter from directly accumulating on the ventilation blades 101, effectively facilitating vehicle 200's wading and off-road conditions, and improving the vehicle's drivability.

[0069] In some embodiments, as Figure 1-2 , Figure 9 As shown, the exhaust assembly 100 further includes a driving mechanism 105 , which is connected to the cover plate 102 to drive the cover plate 102 to move.

[0070] Specifically, the drive mechanism 105 can be a motor, such as a brushed DC motor, a brushless DC motor, a stepper motor, or any other common drive mechanism 105 in the technical field. The drive mechanism 105 can be directly connected to the cover plate 102 or in a transmission connection, providing power for the movement of the cover plate 102 relative to the exhaust port. It will be appreciated that the motor is also provided with a housing 1052 to protect the motor from dust and water ingress.

[0071] In some embodiments, as Figure 1-2 , Figure 8 As shown, the exhaust assembly 100 also includes a transmission mechanism 106, which includes a first connecting rod 1061 and a second connecting rod 1062. One end of the first connecting rod 1061 is connected to the output shaft 1051 of the driving mechanism 105, and the other end is movably connected to the cover plate 102; the second connecting rod 1062 and the first connecting rod 1061 are arranged at an axial interval along the output shaft 1051, one end of the second connecting rod 1062 is movably connected to the cover plate 102, and the other end is suitable for movably connecting to the vehicle 200, the driving mechanism 105 drives the first connecting rod 1061 to rotate, and the first connecting rod 1061 drives the second connecting rod 1062 to drive, so as to drive the cover plate 102 to move; driven by the driving mechanism 105 and the transmission mechanism 106, the cover plate 102 moves translationally in a direction perpendicular to the plane where the exhaust port is located.

[0072] Specifically, the first connecting rod 1061 is engaged with the output end of the motor. The first connecting rod 1061 is an active connecting rod. Driven by the motor output shaft 1051, it drives the cover plate 102 to move relative to the exhaust port. The second connecting rod 1062 is a driven connecting rod. The second connecting rod 1062 is connected to the first connecting rod 1061 through the cover plate 102. Driven by the first connecting rod 1061, the second connecting rod 1062 limits the translational movement of the cover plate 102 in a direction perpendicular to the plane of the exhaust port. The exhaust assembly 100 of the present invention can be arranged between the spare tire 201 and the tailgate 202. Since the movable space of the cover plate 102 is relatively limited, the present invention utilizes the first connecting rod 1061, i.e., the active connecting rod, and the second connecting rod 1062, i.e., the driven connecting rod, to limit the movement of the cover plate 102 relative to the exhaust port to translational movement. This can avoid interference between the cover plate 102 and the exhaust port and requires only a small movable space.

[0073] In some embodiments, as Figure 8 As shown, the second connecting rod 1062 is an arc-shaped connecting rod.

[0074] Specifically, a portion of the second connecting rod 1062 close to the cover plate 102 is designed to be arc-shaped. Since the exhaust assembly 100 of the present invention can be set between the spare tire 201 and the tailgate 202, the movable space of the cover plate 102 is relatively limited. In order to avoid interference between the second connecting rod 1062 and the base 104 of the exhaust assembly 100 in the area close to the cover plate 102, the present invention designs a portion of the second connecting rod 1062 close to the cover plate 102 to be arc-shaped, forming an avoidance space for the rotation path of the second connecting rod 1062, effectively avoiding interference between the second connecting rod 1062 and the base 104 of the exhaust assembly 100, and ensuring that the cover plate 102 moves stably and smoothly.

[0075] In some embodiments, as Figure 8 As shown, the transmission mechanism 106 also includes a fourth connecting rod 1064. The fourth connecting rod 1064 has a main body and a connecting end. The main body is fixedly connected to the cover plate 102. The connecting end has two sub-connecting ends. The two sub-connecting ends are spaced apart axially from the output shaft 1051 and are movably connected to the first connecting rod 1061 and the second connecting rod 1062, respectively. The two sub-connecting ends are a curved first sub-connecting end 10641 and a curved second sub-connecting end 10642. The first sub-connecting end 10641 is movably connected to the first connecting rod 1061, and the second sub-connecting end 10642 is movably connected to the third connecting rod 1063. Along the first direction, the connecting end of the first sub-connecting end 10641 is bent upward, and the connecting end of the second sub-connecting end 10642 is bent downward.

[0076] Specifically, since both the first connecting rod 1061 and the second connecting rod 1062 are connected to the cover plate 102, a connection point is required on the cover plate 102. To reduce the cost of remolding the cover plate 102, the present invention designs a fourth connecting rod 1064. The main body of the fourth connecting rod 1064 is integrally injection molded with the cover plate 102, thereby enhancing the strength of the cover plate 102 while reducing costs. When the exhaust assembly 100 of the present invention is installed on the vehicle 200, the first direction is the height direction of the vehicle 200. The first sub-connecting end 10641 of the fourth connecting rod 1064 bends upward and is rotatably connected to the first connecting rod 1061, and the second sub-connecting end 10642 bends downward and is rotatably connected to the second connecting rod 1062. The exhaust assembly 100 of the present invention can be arranged between the spare tire 201 and the tailgate 202. Since the movable space of the cover plate 102 is relatively limited, the present invention limits the movement of the cover plate 102 relative to the exhaust port to translational movement. Therefore, the present invention designs the first sub-connection end 10641 and the second sub-connection end 10642 to be a special structure that bends upward and downward, and cooperates with the first connecting rod 1061 and the second connecting rod 1062 to realize the translational movement of the cover plate 102 relative to the exhaust port, which can avoid interference between the cover plate 102 and the exhaust port and only requires a smaller movable space.

[0077] In some embodiments, as Figure 1 As shown, the exhaust assembly 100 includes a drive mechanism 105 and a transmission mechanism 106. The transmission mechanism 106 is divided into two groups. The two groups of transmission mechanisms 106 are arranged at intervals along the axis of the output shaft 1051 of the drive mechanism 105. The output shaft 1051 of the drive mechanism 105 has a first shaft 10511 and a second shaft 10511. One of the two groups of transmission mechanisms 106 is connected to the first shaft 10511, and the other group is connected to the second shaft 10511.

[0078] Specifically, the cover plate 102 of the present invention needs to be able to cover the exhaust port. To ensure ventilation efficiency, the exhaust port cannot be too small, so the size of the cover plate 102 cannot be too small. Due to the size limitations of the cover plate 102, and to ensure smoother movement of the cover plate 102, the present invention provides two sets of transmission mechanisms 106 on opposite sides of the cover plate 102. The first connecting rod 1061 of each transmission mechanism 106, i.e., the active connecting rod, is respectively connected to the first shaft 10511 and the second shaft 10511 of the motor output shaft 1051.

[0079] In some embodiments, as Figure 8 As shown, the transmission mechanism 106 also includes a third link 1063, one end of the third link 1063 is engaged with the first link 1061 along a direction intersecting the axis of the third link 1063, and the other end is connected to the output shaft 1051. The driving mechanism 105 drives the third link 1063 to rotate, thereby driving the first link 1061 to rotate around the axis of the third link 1063.

[0080] Specifically, due to the size limitation of the cover plate 102, the present invention sets two sets of transmission mechanisms 106 spaced apart and connected to the output shaft 1051 of the motor. Since the length of the output shaft 1051 of the existing motor is limited, the present invention designs a third connecting rod 1063, one end of which is engaged with the first connecting rod 1061 along a direction intersecting with the axis of the third connecting rod 1063 through a plum key and other structures, and the other end is fixedly connected to the output shaft 1051 of the motor. The third connecting rod 1063 can make up for the defect of limited length of the motor output shaft 1051.

[0081] In some embodiments, as Figure 1-2 , Figure 10 As shown, the exhaust assembly 100 further includes a base 104 and a stopper 107. The base 104 is adapted to be fixedly mounted on the vehicle 200. The drive mechanism 105 is disposed on the base 104. The stopper 107 is disposed on the first connecting rod 1061 or the third connecting rod 1063. The stopper 107 cooperates with the base 104 to limit the range of motion of the cover 102. A boss 1041 is disposed on the base 104, and the stopper 107 is provided with a stop surface 1071. The stop surface 1071 cooperates with the boss 1041 to limit the range of motion of the cover 102.

[0082] Specifically, the exhaust assembly 100 of the present invention also includes a base 104 fixedly mounted on the vehicle 200, a motor is mounted on the base 104, and a stop surface 1071 protruding from the third link 1063 is provided in the axial direction of the third link 1063. Correspondingly, a boss 1041 is provided on the base 104. When the third link 1063 rotates to a certain position, the stop surface 1071 contacts and locks with the boss 1041 to limit the range of motion of the cover plate 102 and avoid interference between the cover plate 102 and the exhaust port.

[0083] In some embodiments, as Figure 5-6 As shown, the cover plate 102 includes a sealing member 1021 , which is disposed on a side of the cover plate 102 facing the exhaust port.

[0084] Specifically, the cover plate 102 of the present invention can selectively cover the exhaust port. When the cover plate 102 covers the exhaust port, in order to achieve a seal of the exhaust port and prevent water ingress, etc., the present invention provides a seal 1021 on the side of the cover plate 102 facing the exhaust port. The seal 1021 and the cover plate 102 are generally formed by secondary injection molding. The seal 1021 can be a common sealing material in the technical field such as TPV material, rubber (nitrile rubber, EPDM rubber, fluororubber, silicone rubber, etc.), and polytetrafluoroethylene. When the cover plate 102 covers the exhaust port, the seal 1021 interferes with the edge of the exhaust port, generating a certain amount of compression, so that the exhaust port has a better sealing effect.

[0085] In some embodiments, the cover plate 102 is provided with a plurality of reinforcing ribs.

[0086] Specifically, since cover plate 102 is typically made of a material such as plastic, which has relatively poor toughness, it is prone to cracking or even breaking when subjected to external impact or after prolonged use. For example, if cover plate 102 is subjected to vibration or minor collisions while the vehicle is in motion, it may be damaged, affecting the sealing effect. Therefore, the present invention provides multiple reinforcing ribs on cover plate 102 to enhance its strength and prevent it from cracking due to bumps and impacts.

[0087] According to an embodiment of the present invention, the air intake system includes the exhaust assembly 100 and an exhaust port, and the exhaust assembly 100 is provided on the exhaust port.

[0088] Specifically, by providing ventilation blades 101 that can be opened by external force and a cover plate 102 that can selectively cover the exhaust port, when the vehicle 200 needs to exhaust, the cover plate 102 does not cover the exhaust port, and when the ventilation blades 101 are driven by the pressure inside the vehicle, such as when the pressure inside the vehicle is greater than the external pressure, the ventilation blades 101 passively open to exhaust, and when the pressure inside the vehicle is less than the external pressure, the ventilation blades 101 are affected by their own gravity and then close, so that the exhaust port realizes one-way ventilation from inside the vehicle to outside the vehicle. At this time, the cover plate 102 covers the exhaust port to avoid the ventilation blades 101 being opened from outside the vehicle to inside the vehicle when the external pressure is greater than the internal pressure in the vehicle under working conditions such as wading. This can prevent the ventilation blades 101 of the vehicle 200 from causing water, dust and other impurities to enter during ventilation, and at the same time prevent the ventilation blades 101 from opening from the outside to the inside of the vehicle, thereby improving the safety of the equipment inside the vehicle and the comfort of the riding environment.

[0089] According to the embodiment of the present invention, the vehicle 200 includes the intake system.

[0090] Specifically, when vehicle 200 is in a wading condition and the water level reaches a set level (not specifically defined herein, but exceeding one-third of the vehicle body height), an electrical signal from the vehicle can be manually transmitted to exhaust assembly 100, causing the motor to drive transmission mechanism 106 to close cover 102, thereby shielding the exhaust port. Optionally, a water level sensor can be provided to automatically control the opening and closing of cover 102 by detecting whether the water level has reached the set level.

[0091] By providing ventilation blades 101 that can be opened by external force and a cover plate 102 that can selectively cover the exhaust port, when the vehicle 200 needs to exhaust, the cover plate 102 does not cover the exhaust port under the drive of the motor. When the ventilation blades 101 are driven by the pressure inside the vehicle, such as when the pressure inside the vehicle is greater than the external pressure, the ventilation blades 101 passively open for exhaust. When the pressure inside the vehicle is less than the external pressure, the ventilation blades 101 are affected by their own gravity and then close, so that the exhaust port realizes one-way ventilation from inside the vehicle to outside the vehicle. At this time, the cover plate 102 covers the exhaust port under the drive of the motor to avoid wading and other working conditions. When the external pressure is greater than the internal pressure of the vehicle, the ventilation blades 101 are opened from outside the vehicle to inside the vehicle, which can prevent the ventilation blades 101 of the vehicle 200 from causing water, dust and other impurities to enter during ventilation, and at the same time prevent the ventilation blades 101 from opening from the outside to inside the vehicle, thereby improving the safety of the equipment inside the vehicle and the comfort of the riding environment.

[0092] In some embodiments, as Figure 11-12 As shown, the vehicle 200 is provided with a spare tire 201 , which is mounted on a back door 202 of the vehicle 200 , an exhaust port is provided between the spare tire 201 and the back door 202 , and the exhaust assembly 100 is provided at the exhaust port.

[0093] Specifically, when the vehicle 200 is wading through deep water, if the exhaust port is positioned low, the probability of water ingress is high. Therefore, the present invention arranges the exhaust port in the cavity between the spare tire 201 and the tailgate 202 sheet metal, which can effectively shield the exhaust assembly 100 and improve the aesthetics; and the exhaust port is arranged at a higher position to prevent the exhaust assembly 100 from failing due to excessive water pressure under wading conditions.

[0094] It is understandable that all the rotatable connections mentioned in the present invention may be conventional rotatable connection structures such as pins and sleeves.
