[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-Figure 4 The utility model provides the following technical solutions: an automobile guard plate with sound insulation and noise reduction function, comprising an automobile guard plate body 1, a mounting hole 101 is opened on the automobile guard plate body 1, and the automobile guard plate body 1 comprises a guard plate top layer 11, a guard plate bottom layer 12 and a surrounding edge 13;
[0026] Depend on Figure 1 and Figure 2 As shown, the top layer 11 of the guard plate and the bottom layer 12 of the guard plate are spaced apart, and the surrounding edge 13 is fixed at the edge of the top layer 11 of the guard plate and the bottom layer 12 of the guard plate. A plurality of equally spaced latitudinal reinforcing ribs 14 and a plurality of equally spaced longitudinal reinforcing ribs 15 are fixed between the top layer 11 of the guard plate and the bottom layer 12 of the guard plate, and the latitudinal reinforcing ribs 14 and the longitudinal reinforcing ribs 15 are staggered and form a plurality of energy absorption cavities 16 on the inner side. Therefore, when in use, the automobile guard plate body 1 is fixed to the bottom of the automobile oil pan. The automobile guard plate body 1 includes the top layer 11 of the guard plate, the bottom layer 12 of the guard plate and the surrounding edge 13. By setting the latitudinal reinforcing ribs 14 and the longitudinal reinforcing ribs 15 and forming a plurality of energy absorption cavities 16, when the automobile guard plate body 1 is collided, the bottom layer 12 of the guard plate will be deformed and the deformation will be absorbed by the plurality of energy absorption cavities 16, without affecting the top layer 11 of the guard plate, thereby avoiding secondary impact on the oil pan and improving safety.
[0027] Depend on Figure 1 and Figure 2As shown, the thickness of the top layer 11 of the guard plate, the thickness of the bottom layer 12 of the guard plate, and the distance between the top layer 11 and the bottom layer 12 of the guard plate are all equal. On the one hand, the latitudinal reinforcement ribs 14 and the longitudinal reinforcement ribs 15 can improve the strength of the automobile guard plate body 1 and reduce the deformation amount generated when the automobile guard plate body 1 is impacted. On the other hand, the deformation generated by the bottom layer 12 of the guard plate will be completely absorbed by the energy absorption cavity 16 to avoid secondary impact on the oil pan.

The noise reduction groove 103 can be formed by stamping. When the noise sound wave is transmitted to the noise reduction groove 103, the noise sound wave will be reflected, and most of the noise sound waves will cancel each other out, thereby achieving noise reduction. The formation of the raised strip 102 can further improve the strength of the automobile guard plate body 1, and can also absorb impact force.
[0029] Depend on Figure 1 As shown, a rubber block 2 is bonded and fixed at a position corresponding to the mounting hole 101 on the bottom surface of the automobile guard plate body 1. After the automobile guard plate body 1 is fixed, the rubber block 2 supports the automobile guard plate body 1 from the bottom. The rubber block 2 is flexible to prevent the automobile guard plate body 1 from shaking and generating noise when the vehicle is driving.
[0030] Depend on Figure 1 and Figure 2 As shown, a rubber ridge 3 is bonded and fixed at the edge of the top surface of the automobile guard plate main body 1. After the automobile guard plate main body 1 is fixed, the automobile guard plate main body 1 and the oil pan squeeze the rubber ridge 3. The rubber ridge 3 is flexible to avoid noise generated by the collision between the automobile guard plate main body 1 and the oil pan when the vehicle is driving.
[0031] Depend on Figure 1 , Figure 2 and Figure 4 As shown, a rubber pad 4 is bonded and fixed to the top surface of the automobile guard plate body 1, and a through hole 41 is opened on the rubber pad 4 at a position corresponding to the noise reduction groove 103. The function of the rubber pad 4 is similar to that of the rubber ridge 3 to prevent the automobile guard plate body 1 from colliding with the oil pan when the vehicle is driving, and the flexibility of the rubber pad 4 can further absorb the noise.
[0032] Depend on Figure 1 , Figure 2 and Figure 4 As shown, the thickness of the rubber ridge 3 is equal to the thickness of the rubber gasket 4. After the automobile guard plate body 1 is fixed, the automobile guard plate body 1 and the oil pan squeeze the rubber ridge 3 and the rubber gasket 4 to avoid noise caused by collision between the automobile guard plate body 1 and the oil pan when the vehicle is driving.
