Description

The present invention relates to a sealing member that covers a gap formed between a rear end portion of a front fender panel of a vehicle such as an automobile and a body panel.

Conventionally, a gap is formed between a front fender panel that covers the tires of the front wheels of a vehicle such as an automobile and a front pillar (body panel) that faces the front fender panel. However, when traveling, noise such as wind noise and engine noise intrudes into the vehicle from this gap, and in order to reduce these noises, a sealing member that closes and seals this gap is provided.

Regarding the above-mentioned sealing member, the technique of Patent Document 1 is known, and the following technique is disclosed. As shown in FIG. 6, the conventional sealing member 300 is composed of a main body portion 400 forming a main portion and an outer peripheral portion 500 formed so as to cover the entire circumference thereof so that the main body portion 400 is hardly exposed. Has been done. Further, a bifurcated lip portion 510 and 510 are integrally molded at one end of the outer peripheral portion 500.

The seal member 300 is fixed by fitting the clip 600 into the through hole 230 and the clip through hole 410 provided in the folded portion 220 of the front fender panel 200. The outer peripheral portion 500 of the seal member 300 is in close contact with the folded portion 220 of the front fender panel 200, and the lip portion 510 expands in a direction in which the lip portions 510 are separated from each other and presses against the front pillar (body panel) 100. It is in close contact with the state.

The main body portion 400 is polypropylene (reinforced PP) reinforced with glass fiber or the like which is a hard material, and the outer peripheral portion 500 is a soft material such as TPE (thermoplastic elastomer). Further, the seal member 300 is manufactured by an injection molding method. In the method, first, the TPE forming the outer peripheral portion 500 is injected into the cavity of the mold, and after a predetermined delay time, the reinforced PP forming the main body portion 400 is injected into the mold to form the reinforced PP. It is manufactured by filling it so as to dig into the inside of the TPE of the outer peripheral portion 500 injected earlier.

Further, Patent Document 2 relates to a rectifying plate 700 that covers the gap between the front fender panel 200 and the body panel 100 in the vicinity of the front corner of the windshield. When forming the lip portion 510 from the main body portion to the outside of the front fender panel 200 (bent portion 210 at a substantially right angle), forming a narrow groove portion according to the thickness of the front fender panel 200 is an injection molding process. As shown in FIG. 7, it is disclosed that a wide groove portion 530 must be formed. Incidentally, in Patent Document 2, EPDM (ethylene propylene / diene non-conjugated polymer) solid rubber, that is, a hard material is used for the rectifying plate 700.

By the way, the front fender panel 200 whose rear end portion shown in Patent Document 2 is bent at a substantially right angle covers the main body portion 400 of Patent Document 1 and the entire circumference thereof almost completely, and the main body portion 400 is almost completely exposed. When the technique of forming the outer peripheral portion 500 is applied so as not to be applied, the groove portion 530 is formed, the bent portion 210 of the front fender panel 200 is inserted, and the lip portion 510 in which the front fender panel 200 and the seal member 300 engage with each other is formed. It is formed thicker than the part to be clipped. As a result, when the reinforced PP forming the main body portion 400 is inserted into the inside of the TPE of the outer peripheral portion 500 previously ejected, the hard main body portion 400 reaches the vicinity of the tip portion of the portion that engages with the front fender panel 200. Inflow.

As a result of the inflow of the rigid main body portion 400, the lip portion 510 that engages with the front fender panel 200 including the groove portion 530 has reduced flexibility. Therefore, the groove portion 530 is assembled to the front fender panel 200 that is bent at a substantially right angle. It becomes difficult. When the wide groove portion 530 shown in Patent Document 2 is formed, the assembling property is improved to some extent, but the sealing property is deteriorated. Further, the groove portion 530 and the bent portion 210 may hit or rub against each other due to vibration or the like, and become a new noise source.

In order to solve the above problems, the present invention according to claim 1 is a sealing member that covers the gap between the front fender panel and the body panel, and the sealing member includes a main body portion made of a hard material and a main body portion. It is composed of an outer peripheral portion made of a soft material to cover, and extends toward the body panel, and extends toward the body panel and engages with the body panel, and extends toward the front fender panel. Then, a fender-side engaging portion that engages with the front fender panel is formed, and a groove portion is formed in the fender-side engaging portion into which the bent portion of the front fender panel in which the rear end of the vehicle is bent inward is inserted. The seal member is characterized in that a recess having a thin outer peripheral portion is formed between the fender side engaging portion and the main body portion.

In the present invention of claim 1, since a concave portion having a thin outer peripheral portion is formed between the fender side engaging portion and the main body portion, injection molding is performed after the outer peripheral portion which is a soft material by the concave portion. It is possible to prevent the main body portion, which is a hard material, from flowing into the fender side engaging portion side from the recess. As a result, the fender side engaging portion can be formed only with a soft material.

The outer peripheral portion formed of the soft material is provided with a fender side engaging portion extending in the direction of the front fender panel and engaging with the front fender panel, and the fender side engaging portion has a vehicle rear end portion. Since a groove is formed inside the vehicle into which the bent portion of the bent front fender panel is inserted, it becomes easy to insert the fender side engaging portion into the bent portion of the front fender panel.

Further, since the fender side engaging portion is made of a soft material, it is easy to expand the groove portion when inserting the bent portion of the front fender panel, and it is not necessary to form the groove portion as wide as in Patent Document 2. Since it can be brought into close contact with each other, sealing property is ensured and noise is not generated.

In the front fender panel, the distance from the body panel is narrowed at the upper tip portion, and the shape tends to be complicated in the continuity of the shape with each front portion of the windshield. From the viewpoint of followability to the shape and sealing property with the front fender panel, a fender-side engaging portion having a groove into which the bent portion of the front fender panel is inserted is desirable.

On the other hand, the front fender panel below the upper tip often has a gently curved shape, so even if it is extended in the direction of the front fender and has a shape that engages with the front fender, the sealing performance is good. Sufficiently secured.

In the present invention of claim 2, the fender side engaging portion that engages with the front fender panel is below the first fender side engaging portion having a groove and a recess formed above and the first fender side engaging portion. Since the rear end of the vehicle is composed of a lip-shaped second fender-side engaging portion that comes into contact with the folded portion of the front fender panel that is folded inside the vehicle, a groove and a recess are formed at the upper tip. The formed first fender-side engaging portion can ensure followability and sealing performance to the complicated front fender panel.

On the other hand, with respect to the front fender panel below the upper tip, the lip-shaped second fender-side engaging portion that is in contact with the folded portion of the front fender panel whose rear end is folded inside the vehicle engages. Therefore, it is not necessary to insert the front fender panel into the groove. As a result, the assembly time can be shortened while ensuring the sealing property.

Since a recess whose outer peripheral portion is thinned is formed between the fender side engaging portion and the main body portion, the main body portion which is a hard material which is injection-molded after the outer peripheral portion which is a soft material by the concave portion. Can be prevented from flowing into the fender side engaging portion side from the concave portion. As a result, the fender side engaging portion can be formed only with a soft material.

The outer peripheral portion formed of the soft material is provided with a fender side engaging portion extending in the direction of the front fender panel and engaging with the front fender panel, and the fender side engaging portion has a vehicle rear end portion. Since a groove is formed inside the vehicle into which the bent portion of the bent front fender panel is inserted, it becomes easy to insert the fender side engaging portion into the bent portion of the front fender panel.

Further, since the fender side engaging portion is made of a soft material, it is easy to expand the groove portion when inserting the bent portion of the front fender panel, and it is not necessary to form the groove portion as wide as in Patent Document 2. Since it can be brought into close contact with each other, sealing property is ensured and noise is not generated.
