Problems solved by technology

The urea tank produced by the blow molding process has high cost and small volume; and it is not easy to control the wall thickness of the tank, which usually leads to excessive wall thickness and waste of raw materials
The cost of rotational molding is relatively high, and the raw materials suitable for rotational molding are limited, the production efficiency is low, and the energy consumption is large
In addition, in the prior art, the urea tank is generally fixed on the car body by binding with cable ties, which takes up a lot of space.
The urea tank assembly on the market generally can only be installed with split sensors or only integrated sensors, which is not very versatile
[0004] To sum up, in the prior art, there is still no effective solution to the problems of light weight, generalization, reduction of the overall structure and material saving of the urea tank.

Abstract

The invention discloses a urea box assembly used for a vehicle. The urea box assembly used for the vehicle solves the problems that in the prior art, a urea box assembly is large in size and poor in universality; and the urea box assembly used for the vehicle has the beneficial effects that the structure is compact, the sealing performance is high, and the weight is small. According to the technical scheme, the urea box assembly comprises a urea box and a support, wherein the urea box is installed on the support, formed through a polypropylene material in an injection molding manner and comprises an upper shell and a lower shell. The top of the upper shell is provided with a sensor installation opening and an injection opening integrally formed with the upper shell in an injection molding manner. The top of the injection opening is provided with an injection opening cover, and an injection opening stopper pre-tightened with the bottom face of the injection opening cover is arranged in the injection opening. The side face of the upper shell is provided with a liquid level window integrally formed with the upper shell in an injection molding manner, and a dirt removing port is formed in the bottom of the lower shell.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a urea tank assembly for a vehicle. Background technique [0002] As the environmental protection departments of various countries proposed to further reduce the nitrogen oxide pollutants emitted by diesel engines, engine manufacturers began to use SCR technology (selective catalytic reduction technology) to meet the requirements of the environmental protection department. Diesel engine exhaust treatment fluid (commonly known as automotive urea, automotive urea, and automotive environmental urea) is a consumable that must be used in SCR technology. [0003] At present, the urea tank is generally formed by blow molding or rotational molding. The urea tank produced by the blow molding process has high cost and small volume; and it is not easy to control the wall thickness of the tank, which usually leads to excessive wall thickness and waste of raw materials. The cost of rotat...
