DETAILED DESCRIPTION

[0019] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 9 As shown, an engine compartment decorative cover mounting structure in this embodiment includes a front end frame 1, an engine compartment decorative cover 2, a shock absorber tower pack reinforcement beam 3 and a mounting assembly, the front portion of the mounting assembly is connected to the front end frame 1, the rear portion of the mounting assembly is connected to the shock absorber tower pack reinforcement beam 3, the left and right sides of the shock absorber tower pack reinforcement beam 3 are used to connect to the vehicle body shock absorber tower pack, and the engine compartment decorative cover 2 is detachably mounted on the mounting assembly.

[0021] The front-end frame 1, the engine compartment decorative cover 2, the shock tower package reinforcement beam 3 and the installation components and other installation structures are not directly connected to the engine, which prevents the engine excitation from being directly transmitted to the installation components and the engine compartment decorative cover 2, and reduces the risk of abnormal shaking, abnormal noise and structural fracture of the engine compartment decorative cover 2, thereby improving the NVH performance of the whole vehicle and improving the customer's driving experience. Among them, NVH refers to Noise, Vibration, Harshness, that is, noise, vibration and acoustic roughness. In addition, the left and right sides of the shock tower package reinforcement beam 3 are connected to the vehicle body shock tower package, which can significantly improve the stiffness of the surrounding structure of the vehicle body shock tower package. The front-end frame 1, the shock tower package reinforcement beam 3 and the installation components are connected to form a frame structure, which can improve the overall stiffness and strength of the cabin area and ensure the safety of the vehicle and the driver and passengers.

[0022] In this embodiment, the mounting assembly includes two mounting brackets 4, and the two mounting brackets 4 are spaced apart in the left-right direction; the two mounting brackets 4 each include a bracket body 41 and a support seat 42 arranged 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-absorbing tower package reinforcement beam 3.

[0023] The spacing between the two mounting brackets 4 can prevent the engine from being blocked, and facilitates 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 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 vertical direction does not change significantly, so that the flatness of the engine decorative cover installation can be taken into account while ensuring the collision energy absorption performance.

[0024] In this embodiment, one or more ball head mounting seats 411 are provided in the middle of the bracket body 41, and rubber vibration isolation pads 21 are provided at positions corresponding to the ball head mounting seats 411 of the engine compartment decorative cover 2, and each of the rubber vibration isolation pads 21 is connected to each of the ball head mounting seats 411. Two ball head mounting seats 411 can be provided in the middle of the two bracket bodies 41, respectively, and four rubber vibration isolation pads 21 are provided on the engine compartment decorative cover 2 accordingly. The ball head mounting seats 411 can be easily assembled, and the connection between the rubber vibration isolation pads 21 and the ball head mounting seats 411 can isolate vibrations, further prevent engine excitation from being directly transmitted to the mounting components and the engine compartment decorative cover 2, and further reduce the risks of abnormal shaking, abnormal noise and structural fracture of the engine compartment decorative cover 2, thereby further improving the NVH performance of the whole vehicle.

[0025] In this embodiment, the engine compartment decorative cover 2 is provided with a vibration isolation pad mounting seat 22 corresponding to the number of the rubber vibration isolation pads 21, and the vibration isolation pad mounting seat 22 includes a reinforcing support rib 221, a support portion 222 and a mounting portion 223, the reinforcing support rib 221 is located on the upper side of the support portion 222, the mounting portion 223 is located on the lower side of the support portion 222, the mounting portion 223 has a through hole 2231 and a plurality of slots 2232, the axis of the through hole 2231 is along the up and down direction, and the opening direction of the plurality of slots 2232 is perpendicular to the axis of the through hole 2231; the upper part of each of the rubber vibration isolation pads 21 is respectively inserted into the corresponding slot 2232 of the vibration isolation pad mounting seat 22, and the lower part of each of the rubber vibration isolation pads 21 extends out from the through hole 2231.

[0026] The opening direction of the slot 2232 of the vibration isolation pad mounting seat 22 is perpendicular to the axis of the through hole 2231. During installation, the rubber vibration isolation pad 21 is installed into the vibration isolation pad mounting seat 22 from the side, thereby achieving easy assembly, and the force direction of the rubber vibration isolation pad 21 is different from the opening direction of the slot 2232, which can make the rubber vibration isolation pad 21 not easy to fall off. The support portion 222 and each slot 2232 can provide support for the rubber vibration isolation pad 21, and the reinforced support rib 221 can provide support for the support portion 222 and increase the overall strength of the vibration isolation pad mounting seat 22, thereby providing reliable support for the rubber vibration isolation pad 21.

[0027] In this embodiment, the support seat 42 includes a 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 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 bracket body 41.
