[0002] As the core powertrain of a vehicle, the stability and safety of the working environment of the car engine directly determine the vehicle's driving performance and service life. Because the bottom of the engine compartment is exposed to the external environment, it is easily affected by external factors such as gravel impact, mud and sand accumulation, and sewage splashing during vehicle operation. Long-term use may lead to wear, corrosion or damage to key components such as the engine oil pan and pipeline joints, which may cause oil leaks, malfunctions and other safety hazards. Therefore, engine guard plates, as key components for protecting the bottom of the engine compartment, have become standard equipment or mainstream optional parts for passenger cars and commercial vehicles.
[0003] An existing automotive engine guard plate, such as Chinese patent application number CN202321312073.5, is easy to fix and includes: a first base plate; a first fixing plate extending upward at an angle from the top of the first base plate; a second fixing plate extending downward at an angle from the top of the first fixing plate; evenly spaced fixing grooves on the first and second fixing plates; a positioning groove on the right side of the second fixing plate; a second base plate extending downward at the bottom of the first base plate; a first U-shaped limiting groove on the right side of the first base plate; a second U-shaped limiting groove at the bottom of the first U-shaped limiting groove, the width of the second U-shaped limiting groove being wider than the first U-shaped limiting groove; and V-shaped protective plates extending upward on both sides of the first and second base plates.
[0004] While existing engine skid plates provide effective protection, they also obstruct engine maintenance and repair, making the process inconvenient and requiring complete removal, which increases the difficulty of maintenance. Furthermore, existing skid plates can negatively impact engine cooling.
[0005] Therefore, we propose a method for easily removing and installing automotive engine guard plates to address the problems mentioned above. Utility Model Content

After the positioning frame and the protective grille are disassembled, the engine can be quickly inspected and maintained, improving the convenience of operation, without the need to completely disassemble the main body of the guard plate.
[0018] Preferably, an energy-absorbing washer is provided at the upper end of the positioning frame, and the energy-absorbing washer is in contact with the inner wall of the inspection groove.
[0019] By adopting the above technical solution, the energy-absorbing washer design can improve the installation stability of the positioning frame, reduce the resonance generated when the vehicle drives over bumpy roads, reduce vibration, and further prevent the second bolt from loosening.
[0020] Compared with the prior art, the beneficial effects of this utility model are: it facilitates the disassembly and assembly of the car engine guard plate;
[0021] 1. By combining columnar damping pads with rubber damping pads, the vibration of the guard plate body can be effectively reduced when the vehicle is driving on bumpy roads, thus improving the overall stability after installation. At the same time, the energy-absorbing washer at the top of the positioning frame can reduce resonance and significantly reduce the probability of the first and second bolts loosening due to vibration, ensuring long-term reliable installation of the guard plate.
[0022] 2. The elongated and equidistantly arrayed air intake holes can guide airflow from the top, forming an air circulation channel with the arrayed through holes at the bottom, which greatly improves the engine cooling effect. The first filter screen inside the through holes and the second filter screen on the left side of the guard plate can effectively block foreign objects from entering and prevent damage to the engine outer wall. In addition, the inspection slot and the positioning frame are connected by the second bolt. The engine can be inspected by removing the positioning frame and the protective grille without removing the entire guard plate, which greatly improves the convenience of operation.
