Problems solved by technology

However, the traditional engine bottom guard generally has the following deficiencies: 1) The sealing performance of the middle part is not strong, which is manifested in the direct use of large openings in the oil filter and oil valve, and the muddy water on the road surface is easy to splash into the engine; 2) In the engine oil The filter, oil valve and other parts are directly sealed with the guard body, which is not convenient for later maintenance; 3) The connection strength between the guard body and the vehicle is low, and it is easy to loosen
However, after a frontal collision of a car equipped with an engine steel plate bottom guard, most of the engine cannot sink successfully, but invades the cab, causing damage to the driver and passengers

Abstract

The invention discloses an engine bottom protecting plate which is made from LFT-D. The bottom protecting plate comprises a protecting plate body, the edge of the protecting plate body protrudes upwards to form a mounting part, and the protecting plate body and the mounting part are integrally molded. The protecting plate body comprises a front part, a rear part opposite to the front part, a left side part and a right side part opposite to the left side part. The mounting part comprises a first mounting part body arranged on the front part, a second mounting part body arranged on the rear part, a third mounting part body arranged on the left side part, and a fourth mounting part body arranged on the right side part. The first mounting part body, the second mounting part body, the third mounting part body and the fourth mounting part body are each provided with positioning mounting holes. A cover plate is arranged on an operation opening and detachably connected with the protecting plate body. The engine bottom protecting plate is high in safety, stable in mounting, convenient to repair later and capable of effectively protecting an engine. The invention further discloses a molding process for preparing the engine bottom protecting plate through the LFT-D technology, and by means of the process, the manufacturing cost and the logistics cost are saved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an engine bottom guard plate and a forming process thereof. Background technique [0002] With the increase of automobile production and sales year by year, there are more and more automobiles on the road. The situation on the ground is complicated, and you often encounter bad road conditions during driving, such as uneven road surface, waterlogged road surface or mud, gravel and other foreign matter splashed in rainy days will splash into the engine compartment, thus causing the engine in the engine compartment, Wiring and electronics are corroded, so some cars are protected by underbody protection. The bottom guard plate protects the chassis, gearbox and engine of the car to a certain extent. It can be said that the engine bottom guard plate is an engine protection device designed according to various models. However, the traditional engine bottom guard generally has the following d...
