Description

Automobile front cover rear sealing strip, automobile front cover sealing structure and automobile

Technical Field

The utility model relates to an automobile seal spare part, concretely relates to automobile front shroud back sealing strip, automobile front shroud seal structure and car.

Background

In general, a passenger car in an automobile includes three parts, an engine compartment, a passenger compartment, and a trunk compartment. The engine compartment may generate harmful hot air and noise due to the operation of the engine. In order to prevent hot air and noise from being transmitted into the passenger compartment to affect the driving experience of passengers, an engine compartment sealing strip, namely a front cover sealing strip, is required to be arranged to seal the engine compartment, and meanwhile, dust and rainwater are prevented from entering the engine compartment to damage other parts. Referring to fig. 1, most passenger cars are classified into an existing front weather strip 5 and an existing rear weather strip 6 according to the location of the weather strip arrangement.

Referring to fig. 2, the existing rear sealing strip 6 shown comprises an existing foamed rubber ring 61 and an existing solid rubber base 62 connected with the existing foamed rubber ring 61, the existing solid rubber base 62 is in an inverted U shape, a steel band 64 is embedded inside the existing solid rubber base, and an existing clamping lip 63 in interference fit with a single existing convex rib 71 on the existing decorating part 7 is arranged in the opening of the U shape. When the automobile front cover is in a closed state, the existing front cover inner plate 8 and the existing foaming rubber ring 61 have certain interference amount, and sealing is realized through elastic deformation of the existing foaming rubber ring 61.

Because the present closely knit rubber base 62 of the type of falling U cooperates with the present protruding muscle 71 of the single strip on the present decoration 7 through present centre gripping lip edge 63, for guaranteeing the reliability of assembly, need support present closely knit rubber base with the help of steel band 64, but because the use of steel band 64, lead to the sealing strip heavier, the cost is higher. In addition, because the existing rear sealing strip 6 realizes the cutting of parts through a cutting process, the steel strips 64 on the cutting sections on the left side and the right side are inevitably exposed, and the steel strips 64 are easy to rust and lose the sealing effect in the later use process of the vehicle, thereby influencing the normal use of users.
