Referring to FIG1 to FIG5, a urea tank assembly structure provided in an embodiment of the present application includes: a urea tank assembly 1, which is used to be connected to an engine wiring harness through a connector 2; a urea pump 4, wherein a first end of the urea pump 4 is connected to the urea tank assembly 1 through a first water channel 61, a second end of the urea pump 4 is connected to the urea tank assembly 1 through a first urea pipeline 62, and a third end of the urea pump 4 is connected to a nozzle through a second urea pipeline 63; a water valve 5, wherein a first end of the water valve 5 is connected to a fourth end of the urea pump 4 through a second water channel 64; and a second end of the water valve 5 is used to be connected to an engine wiring harness; wherein the connector 2, the urea pump 4 and the water valve 5 are all arranged on one side of the urea tank assembly 1.

[0046] The urea tank assembly 1 is used to contain and circulate urea solution, which is usually AdBlue or DEF (Diesel Exhaust Fluid). The urea solution in the urea tank assembly 1 flows through the first urea pipeline 62 into the urea pump 4, and after the pressure is adjusted by the urea pump 4, it is sprayed out from the nozzle through the second urea pipeline 63, and the remaining urea solution flows back to the urea tank assembly 1 through the third urea pipeline 65.

[0047] Among them, the engine wiring harness includes an outlet pipe 31 and a return pipe 32, the first end of the outlet pipe 31 is connected to the connector 2 in the urea tank assembly structure, and the second end is connected to the high-pressure end of the engine cooling water; the first end of the return pipe 32 is connected to the low-pressure end of the engine cooling water, and the second end of the return pipe 32 is connected to the second end of the water valve 5 in the urea tank assembly structure. In this way, the high-temperature cooling water flows from the high-pressure end of the engine cooling water through the water outlet pipe 31 into the urea tank assembly 1, then flows into the urea pump 4 through the first water path 61, flows into the water valve 5 through the second water path 64, and finally returns to the low-pressure end of the engine cooling water from the water valve 5 through the return water pipe 32. In the process of the cooling water flowing through the urea tank assembly 1, the urea pump 4 and the water valve 5 in sequence, the cooling water exchanges heat with the urea solution flowing through the urea tank assembly 1, the urea pump 4 and the water valve 5, so as to avoid the urea solution circulating in each component from being crystallized or frozen at low temperature, resulting in clogging of the pipeline and the nozzle, and ensure that there is enough urea solution to supply the SCR (Selective Catalytic Reduction) system during the operation of the vehicle to decompose the nitrogen oxides in the exhaust gas.

In this way, the connector 2, the urea pump 4 and the water valve 5 are all arranged on one side of the urea tank assembly 1. In this way, the first water channel 61, the second water channel 64, the first urea pipeline 62, the second urea pipeline 63 and the third urea pipeline 65 can be uniformly assembled during the generation process of the urea tank assembly structure. During the assembly of the whole vehicle, after the urea tank assembly structure is fixed, the engine wiring harness is respectively connected to the connector 2, the water valve 5 and the urea pump 4. The assembly can be completed by simply plugging in, which can effectively reduce the complexity of assembly and fully improve production efficiency.

[0054] Optionally, the tank body 11 may be formed by a HDPE (High Density Polyethylene) blow molding process, which has good corrosion resistance, impact resistance and weather resistance. The bottom of the tank body 11 is gradually narrowed to ensure that the supply module 12 can absorb more urea from the tank body 11 as much as possible, thereby increasing the effective volume of the tank body 11.
