Description

BACKGROUND

Field of the Invention

The present invention relates to a door opening portion structure of a vehicle.

background

As the door opening portion structure of a vehicle, a structure is known in which an inner material is arranged along an opening edge of a door opening portion formed in a vehicle body side portion. For the inner material, a configuration is known that includes a side door panel (hereinafter referred to as a first inner material) arranged along a lower edge of the door opening portion and a partition side panel (hereinafter referred to as a second inner material) connected to a front side of the side door panel .

For example, the JP 2015-006862 A a configuration in which end portions of the first inner material and the second inner material lie vertically with a sealing lip interposed therebetween, whereby the first inner material is assembled with the second inner material.

SUMMARY

However, since in the configuration of the JP 2015-006862 A the first inner material, the sealing lip and the second inner material are superposed in the vertical direction, there is a possibility that an opening area of the door opening portion might become smaller.

One aspect of the present invention provides a door opening portion structure of a vehicle that can improve the appearance of a lower edge portion of a door opening portion and can ensure an opening area of the door opening portion.

1. (1) A door opening portion structure of a vehicle according to an aspect of the present invention includes: a first interior material defining a lower edge portion of a door opening portion formed in a vehicle body; and a weather strip attached to the vehicle body in the vehicle width direction further out than the first inner material, the first inner material having an upper step part and a lower step part that is further out in the vehicle width direction than the upper step part, and the weather strip contains strip fastening part attached to the vehicle body and a sealing lip which adjoins an upper side of the strip fastening part on the inside in the vehicle width direction and rests on the lower step part from above.
2. (2) The door opening portion structure of the vehicle according to the above aspect (1) may further include: a second interior material that is adjacent to a front-rear direction first side of the first interior material, and an end portion at that in the front-rear direction first side of the upper step part from above on an inner part of the second inner material in the vehicle width direction, an outer portion in the vehicle width direction of an upper side of the second inner element can smoothly connect to an upper side of the lower step part in the vehicle width direction, and the sealing lip on the in the vehicle width direction larger section of the second inner element can rest from above.
3. (3) In the door opening portion structure of the vehicle according to the above aspect (2), the end portion on the first side in the front-rear direction of the upper step part may be arranged on a side closer to the first side in the front-rear direction is as the lower step part.

According to the above aspect (1), the sealing lip is received in a step portion formed between the upper step part and the lower step part. Therefore, it is possible to minimize an amount of protrusion of the sealing lip from the top of the upper step part compared to a case where the first inner material and the sealing lip are superposed as in the related art. Thus, the appearance of the door opening portion can be improved and an opening area of the door opening portion can be made.

As a result, for example, it is easier for an occupant to get on and off.

As a method of connecting the first inner material to the second inner material, a configuration is also conceivable in which the end faces of the first inner material and the second inner material are supported against each other in the front-rear direction over the entire vehicle width direction.

However, there could be a large gap between in the configuration described above open the end faces, or a gap in the vehicle width direction may not be uniform (for example, V-shaped open, etc.) due to dimensional fluctuations, thermal deformation or the like of the first inner material and the second inner material. As a result, it is conceivable that the appearance of the lower edge portion of the door opening portion could be affected.

Thus, according to the above aspect (2), the end portion near the second inner material in the upper step part rests on the inner part of the second inner material in the vehicle width direction from above. As a result, it is possible to prevent the formation of a gap between the first inner material and the second inner material in the front-rear direction. As a result, the appearance of the door opening portion can be improved.

In addition, according to the above aspect (2), the vehicle width direction outer portion of the top of the second inner material smoothly adjoins the top of the lower step part, and the sealing lip lies on the vehicle width direction outer portion of the second inner material from above on. Therefore, the transition part between the upper step part and the outer portion of the second inner material in the vehicle width direction is covered by the sealing lip. Therefore, a gap between the first inner material and the second inner material can be prevented from being visually recognized in the front-rear direction. In addition, a step-like deformation of the sealing lip can be prevented in a transition part between the lower step part and the outer section of the second inner material in the vehicle width direction. As a result, the occurrence of deformation of the sealing lip can be avoided and the appearance of the door opening portion can be improved.

According to the above aspect (3), the upper step part protrudes to a first side in the front-rear direction from the transition part between the lower step part and the outer width portion of the second inner material in the vehicle width direction. Therefore, even if there is a portion that is not covered with the sealing lip in the transition portion between the lower step portion and the outer width portion of the second inner material in the vehicle width direction, it is possible that a dimension of a gap between the first inner material and the second Internal material occurs to minimize to a minimum. As a result, the appearance of the door opening portion can be improved.

According to this configuration, the second sealing lip is 73 included in the step section between the upper trim step part 41 and the lower cladding part 42 is trained. Therefore, it is possible to have a projection amount of the second sealing lip 73 from the top of the upper trim step part 41 to reduce compared to the case where the first inner material and the sealing lip lie on each other, as in the related art. Thus, the appearance of the door opening section 15 can be improved, and the opening area of the door opening portion 15 be ensured. As a result For example, it is easier for the occupant to get on and off.

A configuration is also conceivable as a method for connecting the side entry panel and the partition side panel in which end faces of the side entrance panel and the partition side panel are supported against each other in the front-rear direction over the entire vehicle width direction.

However, in the configuration described above, a gap between the end faces may open greatly or the gap in the vehicle width direction may not be smooth (for example, V-shaped or the like open) due to dimensional variation, thermal deformation or the like of the side door panel and the partition side panel. As a result, it is conceivable that the appearance of the lower edge portion of the door opening portion is impaired.

Therefore, in the present application, the rear lining part 46 configured so that it is on the front panel from above 44 lies on.

According to this configuration, the rear edge of the rear liner part 46 from above with the front panel 44 covered. As a result, it becomes possible to form a gap in the front-rear direction between the side entrance panel 26 and the partition wall lining 32 to avoid. As a result, the appearance of the door opening section 15 be improved.

In addition, a configuration is used in the present application in which the lower lining step part 57 the partition wall lining 32 smoothly to the top of the lower cladding part 43 connects, and the second sealing lip 73 from above on the lower part of the lining step 47 lies on.
