[0067] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0068] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0069] The following combination Figures 1 to 12 The exhaust treatment apparatus described in the embodiments of this application will be described in detail.

[0070] like Figure 1As shown, the exhaust treatment device includes: an intake assembly 100, a rotating assembly 200, a pressure relief passage, and an adjusting assembly 400. The intake assembly 100 has an intake passage; at least a portion of the rotating assembly 200 is rotatably disposed within the intake passage, and the rotating assembly 200 is used for transmission connection to the power generation device 700; the pressure relief passage is disposed within the intake passage; the adjusting assembly 400 is used to control the opening or closing of the pressure relief passage; when the pressure relief passage is open, airflow passes through the pressure relief passage and enters the pressure reduction chamber 310, thereby reducing the pressure of the gas in the intake passage; when the pressure relief passage is closed, airflow passes through the rotating assembly 200 and enters the pressure reduction chamber 310, thereby causing more gas to drive the rotating assembly 200 to rotate, improving the power generation capacity of the rotating assembly 200.

[0071] Exhaust treatment devices can be used to treat the exhaust gases from the power systems of vehicles. Of course, exhaust treatment devices can also be used to treat other devices that require the emission of gases, and this is not limited to that. For ease of understanding, this application primarily uses the use of an exhaust treatment device in the power system of a vehicle as an example for illustration.

[0072] In related technologies, a power generation component is installed in the gas passage of an exhaust treatment device. When airflow passes through the gas passage, the power generation component operates and generates electricity, thereby recovering the energy of the airflow in the gas passage. However, since the power generation component is located in the gas passage, it affects the gas pressure in the gas passage. When the power system of the vehicle is operating at high speed and high load, the gas pressure in the gas passage is relatively high, which affects the performance of the power system of the vehicle and causes problems such as insufficient driving power. The exhaust treatment device of this application is equipped with a pressure relief passage and an adjustment component 400. The opening or closing of the pressure relief passage can be controlled by the adjustment component 400. When the pressure in the intake passage is... When the pressure is high, the pressure relief channel opens, and the airflow passes through the pressure relief channel into the pressure reduction chamber 310. This reduces the pressure of the gas in the intake channel, preventing excessive pressure from affecting the performance of the driving equipment. When the pressure in the intake channel is low, the pressure relief channel closes, and the airflow passes through the rotating component 200 into the pressure reduction chamber 310. This allows more gas to drive the rotating component 200 to rotate, increasing its power generation capacity. In other words, through the cooperation of the pressure relief channel and the regulating component 400, the exhaust treatment device can generate electricity using the gas in the intake channel without affecting the driving performance of the driving equipment, thus greatly improving the adaptability of the exhaust treatment device.

[0073] In this embodiment, the structure of the air intake assembly 100 is not limited. The air intake assembly 100 may include an air intake pipe body, in which case the cavity of the air intake pipe body forms an air intake channel.

[0074] The number of intake manifolds included in the intake assembly 100 is not limited. For example, in some embodiments, the intake assembly 100 may include only one intake manifold. In other embodiments, the intake assembly 100 may include at least two intake manifolds.

[0075] As an example, such as Figure 1 and Figure 7 As shown, the intake assembly 100 may include: a first intake pipe body 110, a second intake pipe body 120, and a third intake pipe body 130; the first end of the third intake pipe body 130 forms the inlet end of the intake assembly 100, and the second end of the third intake pipe body 130 is connected to the first intake pipe body 110 and the second intake pipe body 120 respectively. The end of the first intake pipe body 110 away from the third intake pipe body 130 and the end of the second intake pipe body 120 away from the third intake pipe body 130 form the outlet end of the intake assembly 100; that is, gas enters from the first end of the third intake pipe body 130, flows into the first intake pipe body 110 and the second intake pipe body 120 respectively at the second end of the third intake pipe body 130, and finally enters the pressure reducing chamber 310 from the first intake pipe body 110 and the second intake pipe body 120.

[0076] Here, the first intake pipe body 110, the second intake pipe body 120, and the third intake pipe body 130 can be different parts of a single structural component. Of course, the first intake pipe body 110, the second intake pipe body 120, and the third intake pipe body 130 can also be different structural components. In this case, the first intake pipe body 110, the second intake pipe body 120, and the third intake pipe body 130 can be connected by welding, bonding, or other methods.

[0077] It should be noted that the inlet end of the intake assembly 100 is generally connected to the exhaust port of the engine of the driving equipment. That is, the exhaust gas generated during the engine operation will be discharged into the intake passage of the intake assembly 100. The gas discharged into the intake passage has a certain pressure, which can drive the rotating assembly 200 to rotate and recover the energy in the engine exhaust gas through the rotating assembly 200.

[0078] The outlet end of the intake assembly 100 is generally located within the pressure reducing chamber 310. The pressure reducing chamber 310 can further reduce the airflow pressure flowing out from the outlet end of the intake assembly 100, thereby reducing the pressure of the exhaust gas and thus reducing noise. The manner in which the pressure reducing chamber 310 is formed is not limited.

[0079] For example, such as Figure 2 and Figure 3As shown, the exhaust treatment device may further include a housing 300 and an exhaust pipe 500. The housing 300 has a pressure-reducing chamber 310 and a first opening 320 and a second opening 330 communicating with the pressure-reducing chamber 310. The inlet end of the exhaust pipe 500 is located inside the pressure-reducing chamber 310, and the outlet end of the exhaust pipe 500 passes through the first opening 320 and is located outside the housing 300. The outlet end of the intake assembly 100 is located inside the pressure-reducing chamber 310, and the inlet end of the intake assembly 100 passes through the second opening 330 and is located outside the housing 300. Gas enters the pressure-reducing chamber 310 from the outlet end of the intake assembly 100, and the pressure is greatly reduced. The gas with reduced pressure is then discharged through the exhaust pipe 500, which can reduce the noise caused by exhaust.

[0080] The structure of the housing 300 is not limited. For example, as... Figure 2 and Figure 4 As shown, the housing 300 may include a cylindrical portion 340, a front cover 350, and a rear cover 360; the front cover 350 is disposed on the front port of the cylindrical portion 340, and the rear cover 360 is disposed on the rear port of the cylindrical portion 340, the cylindrical portion 340, the front cover 350, and the rear cover 360 define a pressure relief chamber 310.

[0081] The cylindrical part 340, the front cover 350 and the rear cover 360 can be connected by welding, bonding or other methods.

[0082] The intake assembly 100 and the front cover 350 can be connected by welding, bonding or other methods, and the exhaust pipe 500 and the rear cover 360 can be connected by welding, bonding or other methods.

[0083] The first opening 320 can be located on the rear cover 360, and the second opening 330 can be located on the front cover 350.

[0084] The exhaust treatment device may further include a support member 600, which is located within the pressure-reducing chamber 310 and divides the pressure-reducing chamber 310 into a first chamber 311 and a second chamber 312. The support member 600 may have a first vent 610 connecting the first chamber 311 and the second chamber 312. The inlet end of the exhaust pipe 500 is located within the first chamber 311, a portion of the exhaust pipe 500 is located within the second chamber 312 and has a second vent 510 connecting the second chamber 312 and the exhaust pipe 500, and the outlet end of the exhaust pipe 500 is located on the second chamber 312 side. The outlet end of the intake assembly 100 is located within the second chamber 312. The 00 portion is located within the first cavity 311, and the inlet end of the intake assembly 100 is located on the side of the first cavity 311. Gas entering and exiting from the outlet end of the intake assembly 100 enters the second cavity 312 of the pressure reducing cavity 310. Part of the gas entering the second cavity 312 enters the first cavity 311 of the pressure reducing cavity 310 through the first vent 610, and then enters the exhaust pipe 500 from the first cavity 311 for discharge. Another part of the gas entering the second cavity 312 directly enters the exhaust pipe 500 from the second vent 510 for discharge. Since the gas entering the second cavity 312 will eventually enter the exhaust pipe 500 through a smaller diameter vent, the noise generated by the exhaust can be further reduced.

[0085] Here, the support member 600 can be provided with multiple first air holes 610, and the exhaust pipe 500 can be provided with multiple second air holes 510.

[0086] Here, the support 600 can be connected to the exhaust pipe 500 and the intake assembly 100 by means of welding, bonding or other methods.

[0087] During production, the support 600 can be connected to the exhaust pipe 500 and the intake assembly 100 first, then the front cover 350 can be connected to the intake assembly 100, and the rear cover 360 can be connected to the exhaust pipe 500, forming a structure as follows: Figure 4 The structure shown is then pressed into the cylindrical part 340, and the cylindrical part 340 is then connected to the front cover 350 and the rear cover 360 respectively.

[0088] In this embodiment, the structure of the rotating component 200 is not limited, as long as the gas in the air intake channel can drive the rotating component 200 to rotate.

[0089] For example, such as Figure 1As shown, in some embodiments, the rotating assembly 200 may include a first rotating shaft 220 and blades 210. At least a portion of the first rotating shaft 220 is rotatably disposed within an air intake channel; the blades 210 are disposed on the first rotating shaft 220; when the airflow in the air intake channel passes through the blades 210, the airflow pushes the blades 210 and the first rotating shaft 220 to rotate together; at this time, the first rotating shaft 220 can be driven to the power generation device 700, thereby driving the rotor of the power generation device 700 to rotate relative to the stator of the power generation device 700, and the power generation device 700 generates electricity.

[0090] The power generation device 700 can be a generator. The electricity generated by the power generation device 700 can be used for the electrical components of the vehicle or stored in the vehicle's battery. As an example, such as... Figure 2 As shown, the power generation device 700 may include a positive electrode portion 730 and a negative electrode portion 740; the positive electrode portion 730 and the negative electrode portion 740 may be connected to the positive and negative terminals of the battery of the vehicle via cables, so as to store the electricity generated by the power generation device 700 in the battery of the vehicle.

[0091] At least a portion of the rotating assembly 200 may be rotatably disposed within the air intake channel; for example, a portion of the rotating assembly 200 may be disposed within the air intake channel, and a portion of the first rotating shaft 220 may be disposed within the air intake channel, with the first rotating shaft 220 located outside the air intake channel and driven to the power generation device 700. Alternatively, at least a portion of the rotating assembly 200 may be rotatably disposed within the air intake channel, or the entire rotating assembly 200 may be disposed within the air intake channel; for example, a portion of the blade 210 may be disposed within the air intake channel, and the entire first rotating shaft 220 may be disposed within the air intake channel, with the first rotating shaft 220 driven to the power generation device 700 within the air intake channel.

[0092] The implementation method in which at least a portion of the first rotating shaft 220 is rotatably disposed within the intake passage is not limited. For example, as Figure 5 and Figure 6 As shown, the exhaust treatment device may also include two bearings 810, which are fixed on opposite sides of the intake channel. The two ends of the first rotating shaft 220 are supported by the two bearings 810, thereby enabling the first rotating shaft 220 to rotate smoothly through the two bearings 810. The blade 210 is located between the two bearings 810.

[0093] The axis of the first rotating shaft 220 may not intersect with the axis of the intake manifold; that is, the rotating assembly 200 is not positioned in the middle of the intake manifold, so that airflow is asymmetrically directed toward the rotating assembly 200, causing the rotating assembly 200 to rotate. As an example, such as... Figure 6As shown, the rotating assembly 200 is disposed on the first intake pipe body 110. The rotation axis A of the rotating assembly 200 and the center line B of the first intake pipe body 110 are not on the same plane, and the rotation axis A of the rotating assembly 200 and the center line B of the first intake pipe body 110 have a set distance H, so that the gas entering the cavity of the first intake pipe body 110 will not be blown symmetrically onto the blade 210, thereby helping to increase the rotation speed of the rotating assembly 200.

[0094] The method by which the rotating component 200 is connected to the power generation device 700 is not limited. For example, such as Figure 2 and Figure 6 As shown, the exhaust treatment device may further include a first flange 820 disposed at the end of the first rotating shaft 220; the power generation device 700 may include a generator, and the generator may include a second flange 710; the connecting side of the second flange 710 is provided with at least two pins 720, and the at least two pins 720 pass through at least two through holes of the first flange 820 to realize the connection between the first rotating shaft 220 and the generator. When the first rotating shaft 220 drives the first flange 820 to rotate, the second flange 710 rotates accordingly, thereby driving the generator to generate electricity.

[0095] The exhaust treatment device may also include a bracket 830 disposed on the housing 300; the bracket 830 is used to fix the power generation equipment 700. The power generation equipment 700 may be fixed to the bracket 830 by bolts 750.

[0096] In this embodiment, the pressure relief channel and the rotating assembly 200 can be disposed in the same intake chamber of the intake channel. Alternatively, the pressure relief channel and the rotating assembly 200 can be disposed in different intake chambers of the intake channel.

[0097] The implementation method of the regulating component 400 for controlling the opening or closing of the pressure relief channel is not limited. For example, the regulating component 400 may include a shielding structure and a control structure, wherein the control structure can control the shielding structure to open or close the pressure relief channel.

[0098] Example 1, such as Figure 7 and Figure 8 As shown, the rotating assembly 200 may include: a blade 210, which is rotatably disposed in the intake passage; a pressure relief passage is a pressure relief hole 211 disposed on the blade 210; by disposing of the pressure relief hole 211 on the blade 210, the space required for the pressure relief passage can be reduced, thereby miniaturizing the exhaust treatment device.

[0099] In Example 1, the rotating assembly 200 may include at least two blades 210, and both blades 210 may be provided with pressure relief holes 211, or may be partially provided with pressure relief holes 211. As an example, such as Figure 11As shown, the rotating assembly 200 may include four blades 210, each blade 210 being provided with a pressure relief hole 211.

[0100] In Example 1, the rotating assembly 200 may also include: a first rotating shaft 220, and the blade 210 may be disposed on the first rotating shaft 220, such as... Figure 9 and Figure 10 As shown.

[0101] In Example 1, the adjustment component 400 may include: a first shield 410, which is movably disposed on the blade 210, and the first shield 410 can open or close the pressure relief hole 211 by movement.

[0102] The structure of the first blocking member 410 is not limited. For example, the first blocking member 410 can be a sheet-like structure.

[0103] The specific form of movement of the first blocking member 410 is not limited. For example, the first blocking member 410 can open or close the pressure relief hole 211 by moving or rotating.

[0104] In Example 1, the adjustment component 400 may further include: a first control element for controlling the movement of the first shield 410 to open or close the pressure relief port 211.

[0105] The structure of the first control component is not limited. For example, the first control component is used to drive the first blocking component 410 to open or close the pressure relief port 211; in this case, the first control component can be a first drive motor, so that the first control component can control the movement of the first blocking component 410 more precisely. Another example is that the first control component is connected to both the first blocking component 410 and the blade 210. The first control component is elastic and is used to control the rotation of the first blocking component 410 through elastic deformation force to close the pressure relief port 211. When the intake pressure in the intake channel is high, the gas can overcome the elastic deformation force of the first control component and directly push the first blocking component 410 to rotate, thus opening the pressure relief port 211. When the intake pressure in the intake channel is low, the first control component controls the first blocking component 410 to close the pressure relief port 211 through elastic deformation force. Therefore, the pressure relief port 211 can be opened or closed by the elastic deformation force of the first control component and the first blocking component 410, resulting in a simple structure and convenient use.

[0106] Of course, the first control component can also be operated manually by the user. In this case, the operating part of the first control component can protrude outside the housing 300. By operating the operating part of the first control component, the first shield 410 can be controlled to open or close the pressure relief hole 211.

[0107] Example 2: The rotating assembly 200 may include: a first rotating shaft 220 and a blade 210, at least a portion of the first rotating shaft 220 being rotatably disposed within an air intake passage; the blade 210 being disposed on the first rotating shaft 220; at least a portion of the blade 210 being movable relative to the first rotating shaft 220; an adjusting assembly 400 being used to control at least a portion of the blade 210 to move relative to the first rotating shaft 220 to a first position or a second position; in the first position, at least a portion of the blade 210 closes the pressure relief passage, at which time airflow passes through the blade 210; in the second position, at least a portion of the blade 210 opens the pressure relief passage, at which time airflow passes through the blade 210 and the pressure relief passage; that is, the pressure relief passage is opened or closed by at least a portion of the blade 210.

[0108] In Example 2, the ability of at least a portion of the blade 210 to move relative to the first axis of rotation 220 may include the ability of a portion of the blade 210 to move relative to the first axis of rotation 220, or it may include the ability of all of the blade 210 to move relative to the first axis of rotation 220.

[0109] As an example, blade 210 is rotatably connected to the first rotating shaft 220; the adjustment assembly 400 is used to control the blade 210 to rotate to a first position or a second position. At this time, the entire blade 210 can rotate relative to the first rotating shaft 220. By rotating the blade 210 relative to the first rotating shaft 220, the area of ​​the air intake passage blocked by the blade 210 can be adjusted, thereby enabling the opening or closing of the pressure relief passage; in the first position, the blade 210 closes the pressure relief passage, and at this time, the airflow passes through the blade 210; in the second position, the blade 210 opens the pressure relief passage, and at this time, the airflow passes through the blade 210 and the pressure relief passage.

[0110] In Example 2, the adjustment component 400 is similar to the first control member described above. The way the first control member controls the movement of the first blocking member 410 is also adapted to the adjustment component 400 for controlling at least a portion of the blade 210 to move relative to the first rotating shaft 220, which will not be described again here.

[0111] In Examples 1 and 2 above, the pressure relief channel and the rotating assembly 200 are located in the same intake chamber of the intake channel; the pressure relief channels in Examples 1 and 2 can also be located simultaneously.

[0112] Example 3: The intake assembly 100 may include: a first intake pipe body 110 and a second intake pipe body 120. At least a portion of the rotating assembly 200 is rotatably disposed within the cavity of the first intake pipe body 110; the second intake pipe body 120 is spaced apart from the first intake pipe body 110; at least a portion of the cavity of the second intake pipe body 120 forms at least a portion of a pressure relief channel; at least a portion of the adjusting assembly 400 is disposed within the second intake pipe body 120.

[0113] In Example 3, the shapes of the segments of the first intake manifold 110 can be the same or different. As an example, such as... Figure 4 As shown, the first intake pipe body 110 includes a mounting section 111. At least a portion of the rotating assembly 200 is rotatably disposed within the cavity of the mounting section 111. The mounting section 111 can be connected to other sections of the first intake pipe body 110 by welding. The cross-sectional area of ​​the mounting section 111 can be set relatively large to accommodate at least a portion of the rotating assembly 200, such as... Figure 5 and Figure 9 As shown.

[0114] In Example 3, a portion of the cavity of the second intake manifold 120 may form at least a portion of the pressure relief channel, and all the cavities of the second intake manifold 120 may also form at least a portion of the pressure relief channel.

[0115] In Example 3, the pressure relief channel can be entirely located within the cavity of the second intake pipe body 120, or it can be partially located within the second intake pipe body 120. As an example, the first part of the pressure relief channel is located within the cavity of the first intake pipe body 110; the second part of the pressure relief channel is located within the cavity of the second intake pipe body 120; the first part of the pressure relief channel can be the structure described in Example 1 and / or Example 2 above.

[0116] In Example 3, when the entire pressure relief channel is located within the cavity of the second intake pipe body 120, the entire adjustment assembly 400 is located within the second intake pipe body 120; when the pressure relief channel is partially located within the second intake pipe body 120, the adjustment assembly 400 is partially located within the second intake pipe body 120, so that the pressure relief channel within the second intake pipe body 120 can be controlled by the adjustment assembly 400 located within the second intake pipe body 120.

[0117] In Example 3, the adjustment assembly 400 may include a second blocking member 420 and a second control member 440. The second blocking member 420 is movably disposed on the second intake manifold 120; the second control member 440 is used to control the second blocking member 420 to open or close at least a portion of the cavity of the second intake manifold 120.

[0118] The second shielding member 420 can be a plate-like structure.

[0119] The movable form of the second shield 420 is not limited. For example, the second shield 420 may be movably disposed in the second air intake pipe body 120. Or, for example, the second shield 420 may be rotatably disposed in the cavity of the second air intake pipe body 120.

[0120] The structure of the second control element 440 is not limited. For example, the second control element 440 is used to drive the second blocking element 420 to move, so as to open or close at least a portion of the cavity of the second air intake pipe body 120; in this case, the second control element 440 can be a second drive motor, so that the second control element 440 can control the movement of the second blocking element 420 more precisely.

[0121] For example, such as Figure 3 , Figure 8 and Figure 12 As shown, the adjustment assembly 400 may further include: a second rotating shaft 430 and a second blocking member 420; at least a portion of the second rotating shaft 430 is rotatably disposed within the cavity of the second air intake pipe body 120; the second blocking member 420 is fixed to the second rotating shaft 430; a first end of a second control member 440 is fixed to the second rotating shaft 430, a portion of the second control member 440 is wound around the periphery of the second rotating shaft 430, and a second end of the second control member 440 is fixed to the second air intake pipe body 120; the second control member 440 is elastic and is used to control the second blocking member 420 to close the second air intake by means of elastic deformation force. At least a portion of the cavity of the second intake pipe 120; when the intake pressure in the intake channel is high, the gas can overcome the elastic deformation force of the second control member 440 and directly push the second blocking member 420 to rotate, so as to open at least a portion of the cavity of the second intake pipe 120; when the intake pressure in the intake channel is low, the second control member 440 controls the second blocking member 420 to close at least a portion of the cavity of the second intake pipe 120 through the elastic deformation force; thus, at least a portion of the cavity of the second intake pipe 120 can be opened or closed by the elastic deformation force of the second control member 440 and the second blocking member 420, which has a simple structure and is easy to use.

[0122] like Figure 4 As shown, the second end of the second control component 440 can be fixed to the column 121 on the outside of the second air intake pipe body 120.

[0123] Of course, the second control member 440 can be operated manually by the user. At this time, the operating part of the second control member 440 can protrude from the housing 300. By operating the operating part of the second control member 440, the second shield 420 can be controlled to open or close at least part of the cavity of the second air intake pipe body 120.

[0124] It should be noted that the above-mentioned methods for setting pressure relief channels can be used in combination or individually. For example, the intake assembly 100 may only include the first intake pipe body 110. In this case, the pressure relief channel can be a pressure relief hole 211 provided on the blade 210 or a pressure relief channel formed by at least a portion of the blade 210 moving relative to the first rotating shaft 220. Another example is... Figures 3 to 6As shown, the intake assembly 100 may include a first intake manifold 110 and a second intake manifold 120. The first intake manifold 110 may not have a pressure relief channel, while at least a portion of the cavity of the second intake manifold 120 forms a pressure relief channel. For example, as... Figures 7 to 11 As shown, the intake assembly 100 may include a first intake pipe body 110 and a second intake pipe body 120. The first intake pipe body 110 may form a pressure relief channel through the pressure relief hole 211 on the blade 210, and at least a portion of the cavity of the second intake pipe body 120 may form a pressure relief channel.

[0125] This application also describes a driving device, which includes an exhaust treatment device and a power generation device 700 according to the embodiments of this application; the rotating component 200 is driven to the power generation device 700; so that the exhaust gas of the driving device can be used by the exhaust treatment device to drive the power generation device 700 to generate electricity.
