[0027] Please refer to Figure 1 As shown, the present application first provides an engine compartment decorative cover, including an outer decorative cover 10, an inner decorative cover 20 and a sealing edge 30. The outer decorative cover 10 and the inner decorative cover 20 are opposite to each other and are spaced apart. The sealing edge 30 is located between the outer decorative cover 10 and the inner decorative cover 20 and is sealed and fixed to the two along the circumferential direction to form a vacuum layer 40 between the two.

[0028] In the present application, the outer decorative cover 10 and the inner decorative cover 20 are spaced apart and the gap therebetween is sealed by edge sealing 30 to form a vacuum layer 40 therebetween. This greatly improves the sound insulation performance of the engine compartment decorative cover of the present application by utilizing the physical property that sound cannot propagate under vacuum conditions, thereby reducing the noise radiated outward through the engine compartment decorative cover, thereby achieving the effect of improving the comfort of the entire vehicle.

[0029] In some embodiments, the outer decoration cover 10 and the inner decoration cover 20 are arranged in parallel, and the distance between them ranges from 0.225 mm to 0.375 mm.

[0030] Preferably, the distance between the outer decorative cover 10 and the inner decorative cover 20 is 0.3 mm.

[0031] Please refer to Figure 1 As shown, in some embodiments, the outer decorative cover 10 and the inner decorative cover 20 are both made of tempered glass, and the engine compartment decorative cover further includes a support bar 41 disposed in the vacuum layer 40 , and the support bar 41 is fixed to the outer decorative cover 10 and the inner decorative cover 20 respectively.

[0032] Compared with other materials, glass has a high surface finish. On the one hand, the smooth glass surface and the sealing effect of the edge seal 30 are relatively good, which can better maintain the vacuum environment in the vacuum layer 40 and prevent the outside air from leaking inward, thereby causing the vacuum layer 40 to fail. On the other hand, the appearance of glass is grand, the visual effect is relatively good, and the decorative effect is also better than that of traditional plastic materials.

[0033] In addition, the support strips 41 can support the exterior decorative cover 10 , thereby effectively improving the structural strength of the engine compartment decorative cover of the present application.

[0034] Please combine Figure 2 、 Figure 3 as well as Figure 4 As shown, in some embodiments, a sealing strip 21 is fixed to the side of the inner decorative cover 20 away from the outer decorative cover 10 , and the sealing strip 21 is annular along the circumferential direction of the inner decorative cover 20 .

[0035] Preferably, the sealing strip 21 includes a fixing portion 211 and a flange portion 212. The fixing portion 211 is fixed to the inner decorative cover 20, and the flange portion 212 extends toward the outside of the inner decorative cover 20 and is inclined toward the direction close to the outer decorative cover 10. The horizontal projection of the flange portion 212 completely covers the vacuum layer 40, so that the flange portion 212 can fit with the edges of the outer decorative cover 10 and the inner decorative cover 20 after installation, thereby further improving the sealing effect of the vacuum layer 40.

[0036] The engine compartment decorative cover of the present application is installed in the decorative cover installation groove on the upper surface of the engine compartment. It is not difficult to understand that when the engine compartment decorative cover is installed, the flange portion 212 will be tightly attached to the edges of the outer decorative cover 10 and the inner decorative cover 20 under the extrusion of the side wall of the decorative cover installation groove. On the one hand, it can improve the sealing effect of the vacuum layer 40, and on the other hand, it can also prevent the engine compartment decorative cover of the present application from colliding with or being squeezed by surrounding components to cause abnormal noise or damage to parts.

[0037] It is worth mentioning that compared with directly fixing the sealing strip 21 to the sides of the outer decorative cover 10 and the inner decorative cover 20, in the structure of the sealing strip 21 of the present application, the inclined flange portion 212 can play a certain guiding role during the installation process of the engine compartment decorative cover, and gradually deform as the engine compartment decorative cover is embedded, so as to improve the installation convenience of the engine compartment cover.

[0038] Please combine Figure 2 、 Figure 3 as well as Figure 4As shown, in some embodiments, at least two positioning pins 22 are fixed to the side of the inner decorative cover 20 away from the outer decorative cover 10, and the positioning pins 22 correspond to the positioning holes on the upper surface of the engine compartment; the inner decorative cover 20 is also fixed to the side away from the outer decorative cover 10 with multiple fixing clips 23, and the fixing clips 23 correspond to the clip holes on the upper surface of the engine compartment.

[0039] The positioning pin 22 is used in conjunction with the fixing buckle 23 to complete the installation of the engine compartment decorative cover; of course, in some other embodiments, the engine compartment decorative cover can also be installed on the engine compartment surface using other commonly used fixing structures, and this application does not make further limitations here.

[0040] Please combine Figure 2 、 Figure 3 as well as Figure 4 As shown, in some embodiments, a vibration isolation sponge 24 is fixed to the side of the inner decorative cover 20 away from the outer decorative cover 10 , and the vibration isolation sponge 24 can provide buffering and vibration isolation effects.

[0041] Specifically, the vibration isolation sponge 24 can play a certain buffering role between the inner decorative cover 20 and the engine compartment surface, preventing the engine compartment decorative cover from colliding or being squeezed with the engine compartment surface due to vibration during engine operation, thereby causing abnormal noise or parts damage.

[0042] More specifically, in some embodiments, the vibration isolation sponge 24 is annular in shape along the circumferential direction of the inner decorative cover 20 , and the vibration isolation sponge 24 is located outside the fixing buckle 23 .

[0043] A second aspect of the present application provides an automobile, comprising the above-mentioned engine compartment decorative cover.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
