Description

Technical Field

[0001] The present invention relates to the technical field of engines, and in particular to a post-processing system and a vehicle. Background Art

[0002] Heavy truck engines are generally equipped with post-processing devices to reduce emissions. The post-processing device will include a three-way catalytic converter, a crankcase forced ventilation system and a fuel evaporative emission control system. The existing technologies all achieve the effect of exhaust gas conversion by evenly coating a coating with a catalyst on the relevant carrier. The catalyst contains precious metals such as platinum and palladium. In order to gain profits, after stealing the post-processing device, on the one hand, special means can be used to refine precious metals for profit, and on the other hand, the stolen assembly can be installed on the same configuration model where the post-processing has been damaged or lost, making illegal profits. However, the post-processing device is very important to the engine. If it is missing, not only will the entire vehicle not be able to operate normally, but the purchase of the post-processing is also quite expensive, causing the owner to suffer very large losses.

[0003] Since the price of heavy truck engine aftertreatment is high, accounting for more than 30% of the engine cost, the theft and trafficking of high-value aftertreatment is a common problem in the market. The theft of aftertreatment causes huge economic losses to vehicle owners. The existing engine aftertreatment system has poor anti-theft capabilities and is very difficult to track after being stolen, making it difficult to trace the vehicle aftertreatment system and the loss of the vehicle owner difficult to recover. Summary of the invention

[0004] In the related art, the engine after-treatment device is expensive and easily stolen and sold. In addition, the existing after-treatment system is difficult to track and recover after being stolen, resulting in losses to the car owner.

[0005] In a first aspect, an embodiment of the present application provides a post-processing system, which includes: a post-processing assembly, a positioning assembly and a temperature difference power generation device; wherein,

[0006] A post-processing assembly, which is used to be installed on the frame of a vehicle; a positioning assembly, which is installed on the post-processing assembly, and the positioning assembly is used to transmit a positioning signal; a temperature difference power generation device, which is installed in the positioning assembly, and the temperature difference power generation device is used to charge the positioning assembly.

[0007] In combination with the first aspect, in one embodiment, one end of the temperature difference power generation device extends into the post-processing assembly, and the other end extends outward and contacts with the surface of the post-processing assembly.

[0008] It is worth noting that the temperature difference power generation device uses the internal heat of the post-processing assembly and the temperature difference of the external surface of the post-processing assembly to generate electricity and store it in the electric storage module. The electric storage module provides a continuous supply of electricity to the GPS module. The GPS signal is received and transmitted through the external metal shell of the post-processing assembly. The car manager system receives the GPS signal, determines the post-processing position, and tracks the post-processing movement trajectory.

[0009] In combination with the first aspect, in one implementation, the positioning assembly is housed inside the post-processing assembly.

[0010] It is understandable that the positioning assembly is built into the post-processing assembly and is relatively concealed, not easy to be discovered or damaged. Even if it is damaged, it will cause structural impact on the post-processing assembly, reducing the value of the post-processing system if it is stolen and sold.

[0011] In combination with the first aspect, in one implementation, the positioning assembly includes:

[0012] A shield, which is installed in the post-processing assembly, wherein a cavity is provided in the shield, and a mounting hole is provided on the shield for the temperature difference power generation device to pass through;

[0013] A positioning unit is accommodated in the shield cavity, and the positioning unit is electrically connected to the temperature difference power generation device.

[0014] In combination with the first aspect, in one embodiment, a heat insulation layer is provided in the cavity of the protective cover, and the heat insulation layer is provided between the positioning unit and the temperature difference power generation device.

[0015] It should be noted that the heat insulation layer divides the cavity of the shield into two areas, wherein the temperature difference power generation device is independently placed in one area to prevent the high temperature of the temperature difference power generation device from damaging the GPS module and the electric storage module.

[0016] In combination with the first aspect, in one implementation, the positioning unit includes:

[0017] A GPS module, which is disposed in the cavity of the shield;

[0018] An electric storage module is electrically connected to the GPS module and the temperature difference power generation device.

[0019] It is worth noting that the electric storage module is used to store the electric energy generated by the temperature difference power generation device to improve the endurance of the GPS module.

[0020] In combination with the first aspect, in one implementation, a mounting bracket is provided on the post-processing assembly, and the mounting bracket can be connected to the vehicle frame via a connecting bolt assembly.

[0021] In combination with the first aspect, in one embodiment, the connecting bolt assembly includes:

[0022] A special-shaped anti-theft bolt, which is used to penetrate the mounting bracket and the vehicle frame;

[0023] The special-shaped anti-theft nut is used to lock the special-shaped anti-theft bolt.

[0024] In combination with the first aspect, in one implementation, the special-shaped anti-theft nut is triangular or pentagonal, and the special-shaped anti-theft bolt is provided with a special-shaped sink.

[0025] It can be understood that anti-theft bolts and nuts are special parts installed on the frame of the post-processing assembly, which require specially designed tools to install and remove. There are irregular triangular, pentagonal and heptagonal countersunk on the head of the anti-theft bolts. Special tools and special-shaped countersunks are used to install and remove the bolts. The outside of the special-shaped anti-theft nuts has irregular triangular, pentagonal and heptagonal surfaces. Special tools are used to clamp the irregular surfaces to install and remove the nuts.

[0026] In a second aspect, an embodiment of the present application provides a car, characterized in that it includes: a post-processing system as described in any one of the above items.

[0027] The beneficial effects brought by the technical solution provided by the embodiment of the present application include at least:

[0028] This application installs a positioning assembly on the post-processing system. Even if the post-processing system is stolen and sold, it can be tracked and retrieved through the positioning assembly to compensate the owner's losses. Furthermore, a temperature difference generator is installed on the positioning assembly to generate electricity through the temperature difference change generated by the positioning system when the post-processing system is working, to maintain the work of the positioning assembly, extend the working time of the positioning assembly, and reduce the difficulty of tracking the post-processing system after it is stolen.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] In the related art, the engine after-treatment device is expensive and easily stolen and sold. In addition, the existing after-treatment system is difficult to track and recover after being stolen, resulting in losses to the car owner.

[0038] It should be noted that the after-treatment system of the engine is expensive, accounting for more than 30% of the total engine cost. Compared with the entire engine, its overall size and weight are relatively small, so it is easy to be stolen and sold, causing losses to the owner.

[0039] First, as Figure 1 and Figure 2 As shown, the present application provides a post-processing system, which includes: a post-processing assembly 1, a positioning assembly 3 and a temperature difference power generation device 4; wherein,

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

[0041] It should be noted that the positioning assembly 3 can always be in communication with the external or vehicle-wide butler system to accurately locate the position of the post-processing system at any time. When the car is turned on, the post-processing is detected to see if it is abnormal, and displayed on the vehicle display and the car butler system. If it is abnormal, check whether the post-processing has been stolen. If it is found to be stolen, check the post-processing positioning path alarm tracking on the butler. When the car is turned off, the initial position of the post-processing is located. If the change in the post-processing position differs from the initial position by 5 meters, the car butler will issue an early warning.

[0042] It is worth noting that in the above embodiment, by installing a positioning assembly on the post-processing system, even if the post-processing system is stolen and sold, it can be tracked and retrieved through the positioning assembly to compensate the owner's losses. Furthermore, a temperature difference generator is installed on the positioning assembly to generate electricity through the temperature difference change generated by the positioning system when the post-processing system is working, to maintain the work of the positioning assembly, extend the working time of the positioning assembly, and reduce the difficulty of tracking the post-processing system after it is stolen.

[0043] In some optional implementations, the positioning assembly 3 is housed inside the post-processing assembly 1 .

[0044] It is understandable that the positioning assembly 3 is built into the post-processing assembly 1, which is relatively concealed and not easy to be discovered or damaged. Even if it is damaged, it will cause structural impact on the post-processing assembly 1, reducing the value of the post-processing system that can be stolen and sold.

[0048] It is worth noting that the temperature difference power generation device 4 generates electric energy by using the internal heat of the post-processing assembly 1 and the temperature difference of the outer surface of the post-processing assembly 1, and stores it in the electric storage module 33. The electric storage module 33 provides a continuous supply of electric energy to the GPS module 32. The GPS signal is received and transmitted through the external metal shell of the post-processing assembly 1. The car manager system receives the GPS signal, determines the post-processing position, and tracks the post-processing movement trajectory.

Even if the post-processing system is stolen and sold, it can be tracked and recovered through the positioning assembly to compensate the owner's losses. Furthermore, a temperature difference generator is installed on the positioning assembly to generate electricity through the temperature difference change generated by the positioning system when the post-processing system is working, to maintain the operation of the positioning assembly, extend the working time of the positioning assembly, and reduce the difficulty of tracking the post-processing system after it is stolen. Furthermore, the present application uses special bolts and nuts, and special tools are required for disassembly and assembly. In addition, there are more than 3 types of bolts and nuts per vehicle, which makes the theft more difficult, prolongs the time it takes to commit a crime, and reduces the risk of theft. In addition, the GPS positioning system is built into the post-processing system, which is relatively concealed and not easy to be discovered or damaged. Even if it is damaged, it will cause structural impact on the post-processing assembly, reducing the value of the post-processing system that is stolen and sold.
