[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-9 As shown, an engine compartment decorative cover mounting structure in this embodiment includes a front frame 1, an engine compartment decorative cover 2, a shock absorber tower reinforcement beam 3, and a mounting assembly. The front part of the mounting assembly is connected to the front frame 1, and the rear part of the mounting assembly is connected to the shock absorber tower reinforcement beam 3. The left and right sides of the shock absorber tower reinforcement beam 3 are used to connect to the vehicle body shock absorber tower. The engine compartment decorative cover 2 is detachably mounted on the mounting assembly.

[0035] The front frame 1, engine compartment trim cover 2, shock absorber tower reinforcement beam 3, and mounting components are not directly connected to the engine. This prevents engine excitation from being directly transmitted to the mounting components and engine compartment trim cover 2, reducing the risk of abnormal vibration, noise, and structural breakage of the engine compartment trim cover 2. This improves the overall NVH performance of the vehicle and enhances the customer's driving experience. NVH refers to Noise, Vibration, and Harshness. Furthermore, the left and right sides of the shock absorber tower reinforcement beam 3 connect to the vehicle body shock absorber tower, significantly improving the rigidity of the surrounding structure. The front frame 1, shock absorber tower reinforcement beam 3, and mounting components together form a frame structure, improving the overall rigidity and strength of the engine compartment area and ensuring the safety of the vehicle and its occupants.

[0036] In this embodiment, the mounting assembly includes two mounting brackets 4, which are spaced apart in the left-right direction. Each mounting bracket 4 includes a bracket body 41 and a support seat 42 disposed on the rear side of the bracket body 41. The front part of the bracket body 41 is connected to the front end frame 1, and the support seat 42 is connected to the shock absorber tower package reinforcing beam 3.

[0037] The spacing between the two mounting brackets 4 can prevent the engine from being blocked, and facilitate the operation of the engine during assembly and after-sales maintenance. The support seat 42 is used to raise the height of the rear side of the bracket body 41, so as to ensure that the bracket body 41 is in a horizontal state, that is, the height of each position of the bracket body 41 in the up-down direction does not change greatly, so that the flatness of the engine cover installation can be considered under the premise of ensuring the crash energy absorption performance.

[0038] In the embodiment, the middle part of the bracket body 41 is provided with one or more ball head mounting seats 411, and the engine compartment cover 2 is provided with rubber vibration isolation pads 21 corresponding to the positions of each ball head mounting seat 411. Each rubber vibration isolation pad 21 is connected with each ball head mounting seat 411. The middle part of each bracket body 41 can be provided with two ball head mounting seats 411, and the engine compartment cover 2 is provided with four rubber vibration isolation pads 21 corresponding to the positions of each ball head mounting seat 411. The ball head mounting seat 411 can facilitate assembly, and the connection of the rubber vibration isolation pad 21 and the ball head mounting seat 411 can isolate vibration, further prevent the direct transmission of engine excitation to the mounting assembly and the engine compartment cover 2, and further reduce the risk of abnormal vibration, abnormal noise and structural fracture of the engine compartment cover 2, so as to further improve the NVH performance of the whole vehicle.

[0039] In the embodiment, the engine compartment cover 2 is provided with vibration isolation pad mounting seats 22 corresponding to the number of rubber vibration isolation pads 21. The vibration isolation pad mounting seat 22 includes a reinforcing support rib 221, a support part 222 and a mounting part 223. The reinforcing support rib 221 is located on the upper side of the support part 222, and the mounting part 223 is located on the lower side of the support part 222. The mounting part 223 has a through hole 2231 and a plurality of insertion slots 2232. The axis of the through hole 2231 is along the up-down direction, and the opening direction of the plurality of insertion slots 2232 is perpendicular to the axis of the through hole 2231. The upper part of each rubber vibration isolation pad 21 is respectively inserted into the insertion slot 2232 of the corresponding vibration isolation pad mounting seat 22, and the lower part of each rubber vibration isolation pad 21 extends out of the through hole 2231.

[0040] The opening direction of the insertion slot 2232 of the vibration isolation pad mounting seat 22 is perpendicular to the axis of the through hole 2231, and the rubber vibration isolation pad 21 is installed from the side into the vibration isolation pad mounting seat 22, so that the assembly is simple and convenient, and the stress direction of the rubber vibration isolation pad 21 is different from the opening direction of the insertion slot 2232, so that the rubber vibration isolation pad 21 is not easy to fall off. The support part 222 and each insertion slot 2232 can provide support for the rubber vibration isolation pad 21, the reinforcing support rib 221 can provide support for the support part 222 and increase the overall strength of the vibration isolation pad mounting seat 22, so as to provide reliable support for the rubber vibration isolation pad 21.

[0041] In the embodiment, the support seat 42 comprises a first connecting portion 421, a first flange 422, and a second flange 423. The bottoms of the first flange 422 and the second flange 423 are respectively connected to the left and right sides of the first connecting portion 421, and the tops of the first flange 422 and the second flange 423 are respectively connected to the left and right sides of the support body 41. In the embodiment, the middle portions of the first flange 422 and the second flange 423 are respectively provided with collapse guide holes 424.

[0042] The first flange 422 and the second flange 423 form a groove for inserting the support body 41, and the support seat 42 and the support body 41 can be connected by welding. The connection form of the support seat 42 and the support body 41 and the collapse guide holes 424 on the support seat 42 can disperse the collision force received by the front end frame 1 to the two support bodies 41 when the vehicle is subjected to a frontal collision or a side collision, and transmit the collision force to the support seat 42 through the two support bodies 41, so that the support seat 42 is deformed and collapsed at the connection portion of the support seat 42 and the connecting body to absorb energy, which is beneficial to improve the overall energy absorption effect of the engine compartment area.

[0043] In the embodiment, the first connecting portion 421 is provided with a first mounting hole 425, and the shock tower package reinforcing beam 3 is provided with a second mounting hole 31 connected with the first mounting hole 425. The first mounting hole 425 and the second mounting hole 31 are connected by bolts.

[0044] In the embodiment, the left part and the right part of the shock tower package reinforcing beam 3 are respectively provided with a plurality of third mounting holes 32 connected with the shock tower package of the vehicle body; and the inner cavity of the shock tower package reinforcing beam 3 is provided with a plurality of reinforcing ribs 33 in the front-rear direction. The number of third mounting holes 32 can be three, and the three third mounting holes 32 can be distributed in a triangular shape. The reinforcing ribs 33 in the shock tower package reinforcing beam 3 can increase the strength and rigidity of the shock tower package reinforcing beam 3, and further improve the rigidity of the structure around the shock tower package of the vehicle body.

[0045] In the embodiment, the inside of the support body 41 is provided with a cavity, the front part of the support body 41 is subjected to planarization treatment to form a flat connecting part 412, the flat connecting part 412 is provided with a fourth mounting hole 413, and the front end frame 1 is provided with a fifth mounting hole 11 for cooperating with the fourth mounting hole 413. The fourth mounting hole 413 and the fifth mounting hole 11 are connected by bolts. The inside of the support body 41 is provided with a cavity to form a hollow beam body, which takes into account the strength and light weight of the support body 41. The flat connecting part 412 is connected with the front end frame 1, the support seat 42 is connected with the shock tower package reinforcing cross beam 3, the flat connecting part 412 is used to reduce the height of the front side of the support body 41, and the support seat 42 is used to raise the height of the rear side of the support body 41, so as to ensure that the support body 41 is in a horizontal state, that is, the height of each position of the support body 41 in the up-down direction does not change greatly, so that the flatness of the engine cover installation can be considered under the premise of ensuring the collision energy absorption performance.

[0046] In the embodiment, the distance between the two mounting supports 4 increases from front to back, and the shape of the two mounting supports 4 is a structure similar to an "isosceles trapezoid", which can improve the overall rigidity and strength of the engine compartment area to ensure the safety of the vehicle and the driver and passengers.
