Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a fuel pre-filter support bracket. Background Technology

[0002] The fuel pre-filter is an important component of the engine supply system. It is a system that processes fuel, removing water and impurities from the fuel. This prevents water in the fuel from reducing engine combustion performance and filters impurities to prevent premature engine wear. The fuel pre-filter is crucial for maintaining high engine efficiency and extending its service life.

[0003] The fuel prefilter includes a primary fuel prefilter and a secondary fuel prefilter arranged in series, both of which are connected to the vehicle frame. In the prior art, the primary and secondary fuel prefilters are usually arranged separately on the vehicle frame. During vehicle assembly, they need to be assembled separately, resulting in dispersed installation processes and hindering the improvement of overall vehicle assembly efficiency. Utility Model Content

[0004] In view of this, the present invention provides a fuel pre-filter support bracket, which realizes a compact arrangement of two-stage fuel pre-filters, eliminating the need for separate assembly of the primary and secondary fuel pre-filters during vehicle assembly. This centralized installation process on the vehicle improves overall assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fuel pre-filter support bracket, connected to a vehicle frame, includes a connecting main board, a first mounting plate, and a second mounting plate.
