Detailed Description

In one embodiment, as shown in fig. 1 and 2. The engine compartment cover rear sealing structure assembly is used for sealing an engine compartment cover and a fender of a vehicle or sealing the engine compartment cover and a compartment beautifying plate 3, and the installation position of the engine compartment cover rear sealing structure assembly is shown in figure 1. In addition, the sealing structure assembly mainly comprises a sealing strip 2 arranged in the engine compartment and two integrally formed sealing gaskets 1 respectively connected to two ends of the sealing strip 2, wherein the sealing gaskets 1 are fixedly connected with a cabin beautifying plate 3 or a fender.

In this embodiment, as shown in fig. 3 and fig. 6, the gasket 1 is L-shaped, and mainly includes a gasket body 10, a limiting member 101 is disposed on the gasket body 10, the limiting member 101 is fixedly connected to the gasket body 10 through a special-shaped member 12, and the external shape of the limiting member 101 is n-shaped or hook-shaped. The sealing gasket 1 is connected with the cabin beautifying plate 3 or the fender through the limiting piece 101, in addition, the limiting piece 101 can limit the position of the sealing gasket 1 while fixing the sealing gasket 1, so that the displacement of the sealing gasket is prevented, and the problems that the sealing gasket 1 deviates or is not firmly connected with the fender cabin beautifying plate 3 to fall off due to the extrusion of the cover plate gravity on the sealing gasket 1 when the sealing gasket 1 is covered on the engine cabin cover plate are effectively solved.

Further, compare with prior art, through the sealed pad 1 of integrated design in this embodiment, eliminated because of split type design and leaded to sealed pad 1 to produce the clearance at the during operation, further promoted the sealed effect of whole seal structure assembly.

The stoppers 101 are not limited to a specific surface of the gasket body 10, and the number and the mounting orientation of the stoppers 101 may be determined according to actual vehicle conditions, the shape of the fender panel, the shape and the position of the cabin cosmetic panel 3, and the like.

In one embodiment, as shown in fig. 4 and 5, a fixing buckle 100 is provided on the gasket body 10, and the gasket body 10 is fixedly connected with the engine compartment or the cabin beautifying plate 3 through the fixing buckle 100.

Further, the gasket body 10 includes a profile 12 and a foaming portion 13 wrapped outside the profile 12. The fixing buckle 100 is arranged on the special-shaped piece 12 and penetrates out of the inner side of the sealing gasket body 10, so that the sealing gasket 1 and the cabin beautifying plate 3 can be firmly connected. The outer layer of the sealing gasket 1 is wrapped with a foaming part 13, the foaming part 13 is made of elastic materials, when the engine compartment cover is closed, a gap generated when the fixed buckle 100 is connected with the engine compartment or the engine compartment beautifying plate 3 can be effectively filled, the noise transmission way is reduced, and the sound insulation effect is improved.

In one embodiment, as shown in fig. 3 and 4. The sealing gasket 1 mainly comprises a body 10 and a groove 11, two ends of the sealing strip 2 are respectively abutted in the sealing gasket grooves 11 on two sides, and the problems that gaps or over-tight assembly and the like can occur during combined assembly due to component tolerance are eliminated, so that the problem that the sealing effect of an engine compartment is not good is solved.

In a further embodiment, as shown in fig. 7 and 8, the groove 11 is provided in the foamed part 13, the groove 11 has a diameter difference from the sealing tape 2, and the diameter of the groove 11 is larger than that of the sealing tape 2, and generally, the diameter difference is in the range of 2-4mm, which can be determined according to the thickness of the sealing tape 2, and when the sealing tape 2 has a small tolerance, the diameter difference of 2mm can be selected; the difference in diameter of 4mm may be selected when the sealing tape 2 has a large tolerance, and 2.5mm or 3.5mm may be selected when there is no tolerance. When the engine compartment cover plate is closed, as shown in fig. 5, the foaming portion 13 is made of an elastic material, so that the groove 11 can be compressed, the diameter difference between the groove 11 and the sealing strip 2 can be eliminated, and the sealing strip 2 and the sealing gasket 1 are attached more tightly.

In addition, in this embodiment, there is the diameter difference in recess 11 and sealing strip 2, still is favorable to the installation of sealing strip 2 for sealing strip 2 can not receive the influence when inserting or extracting, and the later maintenance of being convenient for is changed.
