Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present discussion relates to an opening seal structure between a vehicle door and a pillar.

[0002]

[Prior Art]

 FIG. 1 is a perspective view of a two-door type automobile 10, in which two doors 40 are attached to a vehicle body 20. The door 40 is openably and closably supported by a hinge provided on the front side, and a rear portion of the door 40 is closed by a pillar 50 arranged in a vertical direction of the vehicle body. A seal structure as disclosed, for example, in Japanese Utility Model Laid-Open No. 60-22451 is provided between the door 40 and the pillar 50 to prevent intrusion of raindrops and the like and to prevent wind noise.

FIG. 3 shows an example of a conventional seal structure corresponding to the AA cross section of FIG. A weather strip 60 is fixed to the outside of a panel 52 that constitutes a pillar 50 integrated with the vehicle body 20 with an adhesive 56. The weather strip 60 supports the window glass 80, has a lip portion 62 extending toward the door 40, and is made of a resin such as polyvinyl chloride (PVC). On the other hand, the door 40 has a door panel 42 and a window glass or molding 44 fixed to the outside of the door panel 42. When the door is closed, the edge of the door panel 42 abuts the lip 62 of the weather strip 60 to achieve a seal. With this structure, the surface of the panel front edge portion 54 of the pillar 50 painted in a body color is hidden by the lip portion 62 of the weather strip 60 even when the door 40 is opened, and the appearance can be improved.

Next, in another conventional seal structure shown in FIG. 4, a molding 70 for supporting a window glass 80 on the vehicle body side and a weather strip 74 are provided separately. The weather strip 74 is made of ethylene propylene rubber (EPDM), for example, and has a structure in which a hard portion 75 and a sponge lip portion 77 are integrally molded. The weather strip 74 is attached by fixing the hard portion 75 to the pillar panel with a clip 79. When the door 40 is closed, the door panel 42 pushes the lip portion 77, and the tip of the lip portion 77 is pressed by the molding 70 to achieve sealing.

[0005]

[Problems to be solved by the device]

 The sealing structure of the door opening shown in FIG. 3 causes the PVC weather strip 60 to harden at low temperatures, resulting in coating film friction, poor sealability, and generation of hammering noise when the door is opened and closed. Further, when the temperature is high, the softening occurs, and the lip portion 62 becomes wavy or otherwise defective. In the seal structure of the door opening shown in Fig. 4, the spongy lip 77 made of ethylene propylene rubber, which is inferior in appearance, is conspicuous, and a gap due to dimensional variation occurs in the contact portion between the lip 77 and the molding 70. However, there was a problem that it was difficult to improve the quality. Therefore, the present invention provides a seal structure that eliminates the above-mentioned conventional problems.

[0006]

[Means for Solving the Problems]

 The seal structure of the present invention comprises a weather strip having a main body portion for holding a window glass in a pillar and a lip portion extending from the main body portion to the door opening side, and an inner side fixed to an end portion on the opening side of the door. And a seal member having a curved sponge-like lip portion.

[0007]

[Action]

 When the door is closed, the outer surface of the curved lip portion of the seal member is pressed against the lip portion of the weather strip to achieve the seal.

[0008]

【Example】

 FIG. 2 is a sectional view showing an embodiment of the present invention. The door opening seal structure 100 of the present invention comprises a weather strip member 110 made of polyvinyl chloride or the like fixed to the vehicle body side and a seal member 120 made of ethylene / propylene rubber or the like attached to the door side. It The main body 112 of the weather strip 110 is adhered to the outside of the panel 52 of the pillar 50 on the vehicle body side, and the main body 112 supports the window glass 80 by the groove structure. The weather strip 110 includes a lip 114 extending from the body 112, and the lip 114 covers the front edge 54 of the pillar panel. Therefore, even when the door 40 is opened, the pillar panel is not exposed and the appearance is improved.

In the door 40, a window glass or a molding 140 is fixed on a door panel 42. The seal member 120 attached to the door 40 side is formed of ethylene / propylene rubber material, and has an attachment hole 122 at a key portion. The rear surface of the window glass or molding 140 has a protrusion 142, and is inserted into the hole 122 of the seal member 120 to sandwich and fix the seal member 120 between the window glass or molding 140 and the door panel 42. If necessary, the mounting portion of the seal member 120 can be made hard. The lip portion 124 of the seal member 120 is formed in a sponge shape to give flexibility.

The lip portion 124 is convexly curved, and the outer curved surface thereof is pressed against the outer surface of the lip portion 114 of the weather strip 110. When the door 40 is closed, the sponge-like lip portion 124 formed on the curved surface of the seal member 120 attached to the door side bends inward and comes into close contact with the lip portion 114 on the weather strip 110 side to achieve sealing.

[0011]

[Effect of the device]

 As described above, the sealing structure of the door opening portion of the present invention has a lip portion that covers the pillar panel of the weather strip that is attached to the pillar of the vehicle body, and the sealing member that is attached to the door opening end is curved inward. It has a sponge-like lip portion. Then, when the door is closed, the outer surface of the lip portion of the seal member is pressed against the lip portion of the weather strip to achieve the seal. Since both lip parts contact inside the door panel, the contact part is hidden. Also, since the lip portion of the weather strip covers the pillar panel, the body color is not visible even when the door is opened, improving the appearance. Both lips have flexibility, and deformation of the contact portion due to changes in the outside air temperature is small. Therefore, the sealing performance is improved and wind noise is reduced.
