Abstract

PROBLEM TO BE SOLVED: To surely restrict the intrusion of water even if the surface area of an opening is expanded.SOLUTION: When a tail gate 5 is closed, a curved surface of a circumferential part 13 adheres closely to a lip 11b of a weather strip 11 to deform the lip 11b and the circumferential part 13 adheres closely to the lip 11b of the weather strip 11 in a wide surface area. Even if the position of the weather strip 11 is fluctuated, the curved surface adheres closely to the lip 11b of the weather strip 11 to keep the close adhesion state by the weather strip 11.

Description

  The present invention relates to a lid seal structure that opens and closes an opening of a vehicle.

  An opening of a trunk room or an opening of a door, which is an opening of a vehicle, is opened and closed by a lid member such as a trunk lid or a door. The lid portion having the lid member is provided with a weather strip as a sealing material on the mating surface of the lid member and the opening portion to prevent intrusion of water or the like (see, for example, Patent Document 1).

  In the conventionally known lid portion sealing structure, since the weather strip is interposed, the penetration of water from the mating surface between the lid member and the opening is prevented by the weather strip. For this reason, water intrusion depends on the tightness of the weatherstrip opening and lid, so the path around the opening on the outside of the weatherstrip makes it difficult for water to enter. Such a structure was adopted.

  In order to build a path that is difficult for water to enter due to the shape of the car body, the water that enters from the gap (periphery of the opening) when the lid is closed does not go directly to the weather strip. It is necessary to construct a route. For this reason, a weather strip is interposed in the part away from the peripheral edge of the opening, and the opening area of the opening is restricted.

The state of the mating surface between the tailgate and the peripheral edge of the opening of the luggage compartment is shown.

  As shown in FIGS. 1 and 2, a space for the cargo compartment 3 is secured on the rear side of the rear seat 2 of the vehicle 1, and an opening 4 of the cargo compartment 3 is formed on the rear surface of the vehicle 1. A vehicle body on the upper side of the opening 4 is provided with a tailgate 5 that is pivotable in the vertical direction, and the opening 4 is closed by turning the tailgate 5 downward.

  As shown in FIG. 1, with the tailgate 5 closed, between the tailgate 5 and the vehicle body panel 6 (outer member) at the periphery of the opening 4 and the lamp lens 7 (outer member) of the tail lamp. A gap 8 is formed. In particular, a gap 8 is formed in the same plane as the tailgate 5 between the lower side of the tailgate 5 and the lamp lens 7 and the lower body panel 6.

  As shown in FIG. 2, a rubber weather strip 11 (seal material) is attached to the peripheral edge of the opening 4 of the cargo compartment 3, and the weather strip 11 is attached over the entire periphery of the opening 4. Yes. When the tailgate 5 is closed, the peripheral portion 13 of the inner side surface 12 of the tailgate 5 comes into close contact with the weather strip 11 and the weather strip 11 is deformed.

  A weather strip 11 is provided on the mating surface of the tail gate 5 and the opening 4, and when the tail gate 5 is closed, the peripheral portion 13 of the tail gate 5 is in close contact with the weather strip 11 and deformed. Therefore, the entry of water from the mating surface between the tailgate 5 and the opening 4 into the interior of the luggage compartment 3 is prevented.

  As shown in FIGS. 2 to 4, the peripheral portion 13 of the inner side surface 12 of the tailgate 5 is a curved surface portion that is curved in a concave shape, and the curved surface portion is formed around the entire periphery of the peripheral portion 13 of the tailgate 5 and The part 13 is a concave long groove. For this reason, it can be set as a curved surface part by processing the peripheral part 13 of the tailgate 5 in a bowl shape, and can easily form a curved surface part, without reducing workability. Further, since the curved surface portion is formed on the entire circumference of the peripheral portion 13 of the tailgate 5, the rigidity of the tailgate 5, particularly the rigidity of the peripheral portion of the tailgate 5, is improved, and the opening / closing support mechanism, the lock mechanism, etc. The degree of freedom for installation and design can be increased.

  Based on FIG. 4, the mating surface between the tail gate 5 and the opening 4 at the portion where the lamp lens 7 of the tail lamp is provided will be described in detail. In FIG. 4, the weather strip 11 with the tailgate 5 open is shown by dotted lines.

  As shown in FIG. 4, the holding portion 11a of the weather strip 11 is fitted to the flange portion 15 (peripheral portion) constituting the vehicle body panel 6, and the outside direction of the vehicle body of the holding portion 11a (the lower side in the figure). The lip portion 11b is provided continuously and integrally. The tip of the lip portion 11b is provided with a displacement portion to the outside (left side in the figure) of the opening 4.

  The tail gate 5 is composed of an outer panel 17 and an inner panel 18, and when the tail gate 5 is closed, the outer panel 17 line is continuously formed with the body panel 6 and the lamp lens 7 line of the tail lamp, etc. It is a design.

  When the tailgate 5 is closed, the lip portion 11b of the weather strip 11 is brought into close contact with the curved surface portion of the peripheral portion 13 and crushed. Since the lip portion 11b is in close contact with the curved surface portion, the area of close contact can be increased.

  The extension line of the straight line S in the space connecting the gap 8 between the outer panel 17 of the tailgate 5 and the lamp lens 7 of the tail lamp and the edge 13a of the peripheral portion 13 which is a curved surface curved in a concave shape is the weather strip. 11 is directed to a portion of the lip portion 11b that is closer to the holding portion 11a.

  That is, the water that has entered from the gap is closer to the holding portion 11a side of the weather strip 11 than the straight line S, and the lip portion 11b is in close contact with the peripheral portion 13 without providing a step portion that prevents water from entering. Water does not enter the surface directly. For this reason, even if high-pressure water enters through a gap in a car wash or the like, water does not enter the interior of the luggage compartment 3 from the close contact surface of the lip portion 11b of the weather strip 11.

  Since there is no need to provide a step for preventing water from entering outside the weather strip 11, the weather strip 11 is arranged in the vicinity of the outer periphery of the opening 4 so that the area of the opening 4 is reduced. Can be expanded.

  The sealing structure of the lid portion of the above-described embodiment is wide because the curved surface portion of the peripheral portion 13 is brought into close contact with the lip portion 11b of the weather strip 11 and the lip portion 11b is deformed when the tailgate 5 is closed. The peripheral portion 13 of the tailgate 5 can be brought into close contact with the lip portion 11b of the weather strip 11 in terms of area. Even if the position of the weather strip 11 varies, the peripheral portion 13 of the tailgate 5 is in close contact with the lip portion 11b of the weather strip 11 at the curved surface portion, so that the desired close contact state by the weather strip 11 is maintained. Is done.

  For this reason, the adhesion force of the weather strip 11 can be stably obtained, and even if the weather strip 11 is provided in the vicinity of the periphery of the opening 4 of the vehicle 1 to increase the area of the opening 4, water can surely enter. It becomes possible to prevent.

  In the above-described embodiment, the example in which the seal structure of the tailgate 5 that opens and closes the opening 4 of the luggage compartment 3 of the vehicle 1 is applied as the lid is described. However, the opening that is opened and closed by a trunk lid or a door is described. It is also possible to apply as a sealing structure against the above.
