Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts design, especially relates to a urea tank protective cover plate structure. BACKGROUND

[0002] With the increasingly stringent environmental regulations, especially since the implementation of the national four emission standards, diesel vehicles begin to universally adopt urea injection technology in order to achieve lower emission levels. The core component of this technology, the urea tank and its injection system, has gradually become a standard configuration of all new diesel vehicles. These devices are widely used in urban construction projects, logistics transportation and various commercial vehicles, and they play an important role in various harsh working environments.

[0003] Because these vehicles often operate in dusty, muddy or corrosive environments, the protection requirements for urea tanks and their related parts become particularly stringent. This not only relates to the normal operation of the vehicle, but also is the key to ensuring the precise control of the urea injection system and reducing environmental pollution.

[0004] However, the urea tank has a wide variety of parts, and the design and assembly requirements of the urea tank for each vehicle model are different. This poses a challenge for the main machine factory: how to ensure that the urea tank and its pipeline can be effectively protected and assembled in the production lines of different main machine factories. The traditional method is to add a complete protective cover to the outside of the urea tank, which wraps the entire urea tank system. Although this method can provide protection to some extent, it also brings a series of problems. First, this fully wrapped protective cover increases additional costs, which means higher manufacturing costs for mass production main machine factories. Second, this protective cover is very inconvenient to disassemble and assemble during subsequent market service and maintenance, increasing the difficulty and time cost of repair work. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a urea tank protective cover plate structure with strong adaptability to simplify the structure, reduce costs, improve assembly efficiency and solve the assembly problems of different main machine factories and different workstations.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the utility model provides a urea tank protective cover plate structure with strong adaptability, which comprises a urea tank support, a urea tank arranged on the urea tank support, and a protective cover plate arranged on the top of the urea tank support. The protective cover plate can move horizontally on the urea tank support to adapt to different assembly requirements.

[0007] Preferably, the protective cover plate can move horizontally to shield the urea tank pipeline on the urea tank.

[0008] Preferably, the protective cover plate is provided with a U-shaped slot arranged in the transverse direction, and the urea tank support is used to connect the fastener of the protective cover plate through the U-shaped slot.

[0010] Preferably, the urea tank support is arranged on the whole vehicle frame.

[0011] Preferably, the urea tank pipeline includes a urea tank liquid inlet and outlet pipe, a urea tank water inlet and outlet pipe, and a urea injection pipe.

[0012] The utility model can be implemented through the following steps:

[0013] Firstly, the urea tank is fixed on the urea tank support, and the protective cover plate is installed on the urea tank support in an uncompletely tightened manner, so that the three main parts can be supplied to the host factory as an integrated assembly. Secondly, during the process of assembling the urea tank parts on the production line of the host factory, the operator will first slide the protective cover plate to the end of the urea tank support to expose the space to be assembled, and then install the urea tank pipeline, including the water inlet pipe, the water outlet pipe and the key components such as the urea injection pipe. Finally, when the pipeline installation is completed, the protective cover plate will slide back to the original position to cover and protect the urea tank pipeline, and then the fixing bolt is completely tightened to ensure that the protective cover plate firmly protects the urea tank pipeline. Through this series of steps, the utility model effectively realizes the protection of the urea tank pipeline.

[0014] Compared with the existing urea tank part structure, the utility model has the beneficial effects that:

[0015] 1) By increasing the fixing hole design on the basis of the existing support, the basic structure of the urea tank part is not changed, the part structure is simple, and the cost is low;

[0016] 2) The sliding design of the protective cover plate solves the problem of assembling the urea tank parts in different production factories and different stations, and improves the assembly efficiency;

[0017] 3) The protective cover plate effectively shelters the key position of the urea tank pipeline, improves the service life of the part and reduces the failure rate, and greatly improves the appearance of the part. BRIEF DESCRIPTION OF DRAWINGS
