[0037] In the related art, the engine post-processing device is expensive and is easy to be stolen and sold, and the existing post-processing system is difficult to track and recover after being stolen, resulting in loss to the vehicle owner.

[0038] It should be noted that the post-processing system of the engine is expensive, accounting for more than 30% of the entire engine cost. However, the overall volume and weight of the post-processing system are relatively small compared to the entire engine, so it is easy to be stolen and sold, causing loss to the vehicle owner.

[0039] In a first aspect, as shown in Figure 1 and Figure 2 The present application provides a post-processing system, which comprises: a post-processing assembly 1, a positioning assembly 3, and a thermoelectric power generation device 4; wherein,

[0040] The post-processing assembly 1 is used to be installed on a vehicle frame 2. The positioning assembly 3 is installed on the post-processing assembly 1, and the positioning assembly 3 is used to transmit a positioning signal. The thermoelectric power generation device 4 is installed in the positioning assembly 3, and the thermoelectric power generation device 4 is used to charge the positioning assembly 3.

[0041] It should be noted that the positioning assembly 3 can be in communication with the external or whole vehicle housekeeping system at all times to accurately locate the position of the aftertreatment system at any time. In the starting state of the automobile, whether the aftertreatment is abnormal is detected and displayed on the vehicle display screen and the vehicle housekeeping system. If the aftertreatment is stolen, the housekeeping system can check the positioning path of the aftertreatment and alarm tracking. In the off state of the automobile, the initial position of the aftertreatment is located, and if the position of the aftertreatment changes by more than 5 meters from the initial position, the vehicle housekeeping system will give a warning.

[0042] It should be noted that in the above embodiment, by installing the positioning assembly on the aftertreatment system, even if the aftertreatment system is stolen and sold, it can be tracked back through the positioning assembly to make up for the loss of the vehicle owner. Further, the thermoelectric generator is installed on the positioning assembly, which generates electricity through the temperature difference generated by the positioning system when the aftertreatment system is working, maintains the working of the positioning assembly, prolongs the working time of the positioning assembly, and reduces the tracking difficulty after the aftertreatment system is stolen.

[0043] In some optional embodiments, the positioning assembly 3 is received in the aftertreatment assembly 1.

[0044] It can be understood that the positioning assembly 3 is built into the aftertreatment assembly 1 and is relatively concealed and not easy to be found and damaged.

[0048] It should be noted that the thermoelectric power generation device 4 generates electric energy by utilizing the temperature difference between the heat inside the aftertreatment assembly 1 and the outer surface of the aftertreatment assembly 1, and stores the electric energy in the electric storage module 33. The electric storage module 33 provides the GPS module 32 with a continuous source of electric energy, and the GPS signal is received and transmitted through the metal shell outside the aftertreatment assembly 1. The vehicle housekeeping system receives the GPS signal, judges the position of the aftertreatment, and tracks the movement trajectory of the aftertreatment.

[0052] The GPS module 32 is arranged in the cavity of the shroud 31, and the electric storage module 33 is electrically connected with the GPS module 32 and the thermoelectric generator 4.

[0053] It is worth noting that the electric storage module 33 is used to store the electric energy generated by the operation of the thermoelectric generator 4, thereby improving the endurance of the GPS module 32.

[0054] Further, as shown in Figure 4 The cavity of the shroud 31 is provided with a heat insulation layer 34, and the heat insulation layer 34 is arranged between the positioning unit and the thermoelectric generator 4.

[0055] It should be noted that the heat insulation layer 34 divides the cavity of the shroud 31 into two regions, and the thermoelectric generator 4 is independently placed in one region to prevent the high temperature of the thermoelectric generator 4 from damaging the GPS module 32 and the electric storage module 33.

[0056] In some optional embodiments, as shown in Figure 1 and Figure 2 The aftertreatment assembly 1 is provided with a mounting bracket 5, and the mounting bracket 5 is connected with the vehicle frame 2 through a connecting bolt assembly 6.

[0057] Further, the mounting bracket 5 comprises a mounting beam 51 and a bracket body 52, the bracket body 52 is connected with the vehicle frame 2 through the connecting bolt assembly 6, one side of the mounting beam 51 is connected with the aftertreatment assembly 1, and the other side is connected with the bracket body 52.

[0060] Further, the special-shaped anti-theft nut 62 is triangular, and the special-shaped anti-theft bolt 61 is provided with a special-shaped sink 611. Optionally, as shown in the figure, the special-shaped sink 611 can also be selected as a pentagonal structure. Figure 3

[0061] It can be understood that the anti-theft bolt and nut are special parts for installing the aftertreatment assembly 1 on the vehicle frame 2, and special tools need to be designed for installation and disassembly. The anti-theft bolt head has irregular triangular, pentagonal and heptagonal sinks, and the special tools and the special-shaped sink 611 are matched to install and disassemble the bolt. The outer surface of the special-shaped anti-theft nut 62 is irregular triangular, pentagonal and heptagonal surface, and the special tool clamps the irregular surface to install and disassemble the nut.

[0062] In a second aspect, the application provides an engine comprising an aftertreatment system, which comprises: an aftertreatment assembly 1, a positioning assembly 3 and a thermoelectric generator 4; wherein,

The positioning assembly 3 is installed on the aftertreatment assembly 1, and the positioning assembly 3 is used for transmitting a positioning signal. The thermoelectric generator 4 is installed in the positioning assembly 3, and the thermoelectric generator 4 is used for charging the positioning assembly 3.

[0064] It should be noted that the positioning assembly 3 can always be in communication with the external or vehicle housekeeping system, so as to accurately position the position of the aftertreatment system at any time. In the starting state of the automobile, whether the aftertreatment is abnormal is detected, and displayed on the vehicle display screen and the vehicle housekeeping system. If the aftertreatment is stolen, the vehicle housekeeping system can check whether the aftertreatment is stolen, and if the aftertreatment is stolen, the vehicle housekeeping system can check the positioning path of the aftertreatment and alarm tracking. In the off state of the automobile, the initial position of the aftertreatment is positioned, and if the position of the aftertreatment changes by more than 5 meters from the initial position, the vehicle housekeeping system can perform early warning.

[0065] It is worth noting that in the above embodiment, by installing the positioning assembly on the aftertreatment system, even if the aftertreatment system is stolen and sold, the positioning assembly can be tracked to recover it, and the loss of the vehicle owner can be compensated. Further, the thermoelectric generator is installed on the positioning assembly, and the thermoelectric generator generates electricity through the temperature difference generated by the working of the aftertreatment system, maintains the working of the positioning assembly, prolongs the working time of the positioning assembly, and reduces the tracking difficulty after the aftertreatment system is stolen.

[0066] In some optional embodiments, the positioning assembly 3 is accommodated in the aftertreatment assembly 1.

[0067] ​It can be understood that the positioning assembly 3 is built in the aftertreatment assembly 1 and is relatively concealed and not easy to be found and damaged. Even if it is damaged, it will have structural impact on the aftertreatment assembly 1 and reduce the value of the aftertreatment system for being stolen and sold.

[0068] In some specific embodiments, as shown in Figure 4 and Figure 5 The positioning assembly 3 comprises a shield 31 and a positioning unit.

[0069] The shield 31 is installed in the aftertreatment assembly 1, and the shield 31 is provided with a cavity. The shield 31 is provided with a mounting hole 311 through which the thermoelectric generator 4 passes. The positioning unit is accommodated in the cavity of the shield 31 and is electrically connected with the thermoelectric generator 4.

[0070] In some preferred embodiments, in order to improve the power generation efficiency of the thermoelectric generator 4, one end of the thermoelectric generator 4 extends into the aftertreatment assembly 1, and the other end extends outward and contacts the surface of the aftertreatment assembly 1.

[0071] It is worth noting that the thermoelectric generator 4 generates electric energy by utilizing the temperature difference between the internal heat of the aftertreatment assembly 1 and the external surface of the aftertreatment assembly 1, and stores the electric energy in the electric storage module 33. The electric storage module 33 provides the GPS module 32 with a continuous supply of electric energy. The GPS signal is received and transmitted through the external metal shell of the aftertreatment assembly 1. The car manager system receives the GPS signal, judges the aftertreatment position, and traces the aftertreatment motion trajectory.

[0072] Optionally, the shield 31 is a hollow cuboid with an opening. The shield 31 is arranged inside the aftertreatment assembly 1, and the opening end of the shield 31 is butted against the external surface of the aftertreatment assembly 1. One end of the electrode of the thermoelectric generator 4 passes through the mounting hole 311 of the shield 31 and rises into the aftertreatment assembly 1, and the other end contacts the external surface of the aftertreatment assembly 1.

[0073] It can be understood that the temperature difference between the two ends of the electrode of the thermoelectric generator 4 is relatively large, which is beneficial to power generation.

[0074] Specifically, the positioning unit comprises a GPS module 32 and an electric storage module 33.

[0075] The GPS module 32 is arranged in the cavity of the shield 31. The electric storage module 33 is electrically connected with the GPS module 32 and the thermoelectric generator 4.

[0076] It is worth noting that the electric storage module 33 is used to store the electric energy generated by the operation of the thermoelectric generator 4, thereby improving the endurance of the GPS module 32.

[0077] Further, as shown in Figure 4 The cavity of the shield 31 is provided with a heat insulation layer 34 between the positioning unit and the thermoelectric generator 4.

[0078] It should be noted that the heat insulation layer 34 divides the cavity of the shield 31 into two regions, and the thermoelectric generator 4 is independently placed in one region to prevent the high temperature of the thermoelectric generator 4 from damaging the GPS module 32 and the electric storage module 33.

[0084] It can be understood that the anti-theft bolt and nut are special parts for installing the aftertreatment assembly 1 on the vehicle frame 2. Special tools are needed for installation and removal. The anti-theft bolt head has irregular triangular, pentagonal, and heptagonal sinks. Special tools and special anti-theft sinks 611 are used to install and remove the bolts. The outer surface of the special anti-theft nut 62 is irregularly triangular, pentagonal, and heptagonal. Special tools are used to clamp the irregular surface to install and remove the nut.

[0085] In a third aspect, the application provides an automobile including an aftertreatment system, which includes an aftertreatment assembly 1, a positioning assembly 3, and a thermoelectric generator 4.

[0086] A rear treatment assembly 1 is mounted on a vehicle frame 2. A positioning assembly 3 is mounted on the rear treatment assembly 1, and the positioning assembly 3 is used to transmit a positioning signal. A thermoelectric generator 4 is mounted in the positioning assembly 3, and the thermoelectric generator 4 is used to charge the positioning assembly 3.

[0087] It should be noted that the positioning assembly 3 can always be in communication with the external or whole vehicle housekeeping system to accurately position the rear treatment system at any time. In the starting state of the automobile, whether the rear treatment is abnormal is detected and displayed on the vehicle display screen and the vehicle housekeeping system. If the rear treatment is stolen, the housekeeping system can check whether the rear treatment is stolen, and if the rear treatment is stolen, the housekeeping system can check the positioning path of the rear treatment and alarm tracking. In the off state of the automobile, the initial position of the rear treatment is positioned, and if the position of the rear treatment changes by more than 5 meters from the initial position, the vehicle housekeeping system can perform early warning.

[0088] It should be noted that in the above embodiment, by mounting the positioning assembly on the rear treatment system, even if the rear treatment system is stolen and sold, the positioning assembly can be tracked to recover the stolen rear treatment system, thereby reducing the loss of the vehicle owner. Further, the thermoelectric generator is mounted on the positioning assembly, and the thermoelectric generator generates electricity through the temperature difference generated by the operation of the rear treatment system to maintain the operation of the positioning assembly, thereby prolonging the operation time of the positioning assembly and reducing the tracking difficulty of the stolen rear treatment system.

[0089] In some optional embodiments, the positioning assembly 3 is received in the rear treatment assembly 1.

[0090] It can be understood that the positioning assembly 3 is built in the rear treatment assembly 1, which is relatively concealed and not easy to be found and damaged. Even if it is damaged, it will affect the structure of the rear treatment assembly 1 and reduce the value of the stolen rear treatment system.

[0091] In some specific embodiments, as shown in Figure 4 and Figure 5 The positioning assembly 3 comprises a shield 31 and a positioning unit.

[0092] The shield 31 is mounted in the rear treatment assembly 1, and the shield 31 has a cavity therein. The shield 31 has a mounting hole 311 for the thermoelectric generator 4 to pass through. The positioning unit is received in the cavity of the shield 31, and the positioning unit is electrically connected with the thermoelectric generator 4.

[0093] In some preferred embodiments, in order to improve the power generation efficiency of the thermoelectric generator 4, one end of the thermoelectric generator 4 extends into the rear treatment assembly 1, and the other end extends outward and contacts the surface of the rear treatment assembly 1.

[0094] It is worth noting that the thermoelectric generator 4 utilizes the temperature difference between the internal heat of the after-processing assembly 1 and the external surface of the after-processing assembly 1 to generate electrical energy, which is stored in the electrical storage module 33. The electrical storage module 33 provides a continuous power supply to the GPS module 32. The GPS signal is received and transmitted through the external metal casing of the after-processing assembly 1. The vehicle management system receives the GPS signal, determines the location of the after-processing unit, and tracks its movement trajectory.

[0095] Optionally, the shield 31 is a hollow cuboid with an opening, and the shield 31 is arranged inside the post-processing assembly 1, with the open end of the shield 31 abutting against the outer surface of the post-processing assembly 1. One end of the electrode of the thermoelectric generator 4 passes through the mounting hole 311 of the shield 31 and rises into the interior of the post-processing assembly 1, while the other end contacts the outer surface of the post-processing assembly 1.

[0096] It is understandable that the electrodes of the thermoelectric generator 4 form a large temperature difference between the internal and external surfaces of the post-processing assembly 1, which is beneficial for power generation.

[0097] Specifically, the positioning unit includes: a GPS module 32 and an electrical storage module 33; wherein,

[0098] GPS module 32 is located inside the cavity of the protective cover 31; electrical storage module 33 is electrically connected to GPS module 32 and thermoelectric generator 4.

[0099] It is worth noting that the electrical storage module 33 is used to store the electrical energy generated by the thermoelectric generator 4, thereby improving the battery life of the GPS module 32.

[0100] Furthermore, such as Figure 4 As shown, a heat insulation layer 34 is provided inside the cavity of the protective cover 31, and the heat insulation layer 34 is located between the positioning unit and the thermoelectric generator 4.

[0101] It should be noted that the heat insulation layer 34 divides the cavity of the protective cover 31 into two areas, in which the thermoelectric generator 4 is placed independently in one area to prevent the high temperature of the thermoelectric generator 4 from damaging the GPS module 32 and the electrical storage module 33.

[0102] In some alternative implementations, such as Figure 1 and Figure 2 As shown, the aftertreatment assembly 1 is provided with a mounting bracket 5, which can be connected to the vehicle frame 2 via a connecting bolt assembly 6.

[0103] Furthermore, the mounting bracket 5 includes a mounting beam 51 and a bracket body 52, the bracket body 52 being connected to the vehicle frame 2 via a connecting bolt assembly 6. One side of the mounting beam 51 is connected to the aftertreatment assembly 1, and the other side is connected to the bracket body 52.

[0104] Some preferred embodiments, as shown in Figure 2 and Figure 3 The connecting bolt assembly 6 includes: a special anti-theft bolt 61 and a special anti-theft nut 62; wherein,

[0105] The special anti-theft bolt 61 is used for being arranged in the mounting bracket 5 and the vehicle frame 2; and the special anti-theft nut 62 is used for locking the special anti-theft bolt 61.

[0106] Further, the special anti-theft nut 62 is triangular, and the special anti-theft bolt 61 is provided with a special shaped sink 611. Optionally, as shown in Figure 3 the special shaped sink 611 can also be selected as a pentagonal structure in the figure.

[0107] It can be understood that the anti-theft bolt and nut are special parts for installing the aftertreatment assembly 1 on the vehicle frame 2, and special tools need to be designed for installation and disassembly. The anti-theft bolt head has irregular triangular, pentagonal and heptagonal sinks. The special tool cooperates with the special shaped sink 611 to install and disassemble the bolt. The outer surface of the special anti-theft nut 62 is irregular triangular, pentagonal and heptagonal. The special tool clamps the irregular surface to install and disassemble the nut.

[0108] In summary, the present application installs the positioning assembly on the aftertreatment system. Even if the aftertreatment system is stolen and sold, it can be tracked back through the positioning assembly to make up for the loss of the vehicle owner. Further, the positioning assembly is provided with a thermoelectric generator. The thermoelectric generator generates electricity through the temperature difference generated by the positioning system when the aftertreatment system works, maintains the work of the positioning assembly, prolongs the working time of the positioning assembly, and reduces the tracking difficulty after the aftertreatment system is stolen. Further, the present application uses special bolts and nuts. Special tools are needed for disassembly and assembly. The types and structures of the bolts and nuts exceed 3 per vehicle, which increases the difficulty of theft and extends the time of the crime, thereby reducing the risk of theft. In addition, the GPS positioning system is built in the aftertreatment, which is relatively concealed and not easy to be found and damaged. Even if it is damaged, it will affect the structure of the aftertreatment assembly and reduce the value of the stolen and sold aftertreatment.
