Next, embodiments of the present specification will be described in detail.

Referring to fig. 1 to 4, the present utility model provides a hood sealing structure for sealing an engine compartment, and ensuring the sealing performance of the engine compartment. The engine compartment includes an engine cover 10, a front bumper 20, and fenders 30 provided on both sides of the front bumper 20. In the present embodiment, the engine compartment further includes an engine compartment beautification plate 60, and the engine compartment beautification plate 60 is in contact with the front bumper 20 and the fender 30, covering an exposed portion of the engine compartment such as an engine or the like.

Referring to fig. 1 and 2, the hood sealing structure includes a front end weather strip 40 provided between the hood 10 and the front bumper 20, and a fender weather strip 50 provided between the hood 10 and the fender 30. The front seal 40 includes a bulb 41 and a front seal upper mantel 42. The bulb 41 is in contact with the hood 10 and the front bumper 20, and the front-end weather-strip upper shroud 42 is located at the rear end of the bulb 41 and is in contact with the hood 10.

Front seal 40 also includes a front seal lower mantel 43, front seal lower mantel 43 being located below front seal upper mantel 42. The front seal upper mantel 42 extends obliquely upward from the bubble tube portion 41, and the front seal lower mantel 43 extends obliquely downward from the bubble tube portion 41.

The hood 10 includes a hood outer panel 11 and a hood inner panel 12. Specifically, the bubble tube portion 41 is interference fit with the hood outer panel 11 and the front bumper 20, and the front end weather strip upper mantel 42 is interference fit with the hood inner panel 12.

The bubble tube portion 41 seals a gap between the hood 10 and the front bumper 20. The bubble tube portion 41 is generally made of rubber having a certain elasticity and sealing property, such as EPDM, so that the bubble tube portion 41 can be interference fit with the hood outer panel 11 and the front bumper 20 when the hood 10 is closed, ensuring the sealing property.

The front end weather strip upper mantel 42 contacts the hood inner panel 12 and forms a cavity with the bubble tube portion 41 and the engine hood 10. The cavity can additionally add a layer of sealing structure on the basis that the foam tube part 41 seals the hood outer plate 11 and the front bumper 20, so that the sealing performance of the engine room after the foam tube part 41 is damaged is ensured.

The bubble tube portion 41 includes an upper bubble tube portion 411 and a lower bubble tube portion 412. The upper portion 411 of the bulb is arcuate in cross-section. The upper portion 411 of the bulb is interference fit with the hood outer panel 11 and the front bumper 20. The lower portion 412 of the bulb includes a bottom edge 412a, a first side edge 412b and a second side edge 412c disposed at two ends of the bottom edge 412 a.

First side 412b is remote from front end weatherstrip upper mantel 42 and is interference fit with front bumper 20. Second side 412c is adjacent front seal upper mantel 42 and is connected to front seal lower mantel 43. The upper portion 411 and the lower portion 412 of the bulb form a bulb lumen 413. The front end weatherstrip 40 further includes a front end weatherstrip clip 44 located below the bubble tube 41, the front end weatherstrip clip 44 being mounted on the front bumper 20.

The bubble tube chamber 413 can reserve a deformation space for the upper part 411 of the bubble tube which is in interference fit with the hood outer panel 11 and the front bumper 20 and the first side 412b which is in interference fit with the front bumper 20, and prevent damage caused by contact with the bottom edge 412a and the second side 412c due to excessive deformation. At the same time, the bubble vial lumen 413 may also accommodate the front end sealing clasp 44. The front end seal clasp 44 may be a plastic clasp. Front sealing clasp 44 is secured to bottom edge 412 a. The front end seal strip 40 is mounted to the front bumper 20 by a front end seal clip 44.

In one embodiment, the bulb portion 41 as a whole may be made of rubber having a certain elasticity and sealability. In an alternative embodiment, the bubble tube 41 may also be made partly of a sponge rubber with a certain elasticity and sealing property, and partly of a compact rubber. For example, the bottom edge 412a is made of compact glue, and the compact glue structure is compact, so that the bottom edge 412a can be more tightly connected with the front bumper 20 through the front end sealing strip buckle 44; the rest of the foam tube 41 is made of sponge rubber, which has certain elasticity and sealing property and can ensure interference fit with the engine cover 10 and the front bumper 20.

The front end weather strip upper mantel 42 extends obliquely upward from the bulb tube portion 41 and contacts the hood inner panel 12. The front end weather strip lower mantles 43 extend obliquely downward from the bulb tube portions 41 and then are interference fit with the engine compartment beautification plates 60. The front end seal strip lower mantles 43 and the front end seal buckles 44, which are in interference fit with the engine compartment beautifying plate 60, can enable the front end seal strip 40, the front bumper 20 and the engine compartment beautifying plate 60 to form a stable connection structure, and ensure the tightness of the engine compartment.

As shown in fig. 2 to 4, the fender seal strip 50 includes a fender seal strip mantel 51 that is interference fit with the hood inner panel 12. Fender seal mantel 51 is identical in profile and interengages with front seal upper mantel 42. After assembly, fender seal mantel 51 contacts the edge of front seal upper mantel 42 and makes a smooth transition therebetween.

The fender seal 50 further includes a fender seal clip 52 and a fender seal connection portion 53, and the fender seal clip 52 is assembled to the engine compartment beautification plate 60. The fender seal mantel 51 is connected to the fender seal connection 53, the fender seal buckle 52 is provided to the fender seal connection 53, and the fender seal 50 is mounted to the engine compartment beautification plate 60 via the fender seal buckle 52 and the fender seal connection 53. The fender seal clip 52 may be a plastic clip.

The utility model also provides an automobile, which comprises the engine cover sealing structure.

According to the utility model, the front end sealing strip upper mantel 42 and the bubble pipe part 41 are in contact with the engine cover 10, wherein the bubble pipe part 41 is in interference fit with the engine cover outer plate 11, the front end sealing strip upper mantel 42 is in interference fit with the engine cover inner plate 12, two seals are formed between the front end sealing strip 40 and the engine cover 10, and the tightness of an engine cabin is improved.

Further, the profile of the fender seal bar mantel 51 is the same as that of the front end seal bar upper mantel 42, and the front end seal bar 40 and the fender seal bar 50 are in smooth transition, so that dislocation in the X direction and the Z direction between the front end seal bar 40 and the fender seal bar 50 is avoided, and the tightness and the attractiveness of the engine compartment are improved.
