Description

The present invention
The present invention relates to a structure of a mating portion of a first interior member and a second interior member that covers a vehicle body panel in a state of being adjacent to each other.

As an example of the above-described vehicle interior member mating portion structure, there is a technique disclosed in Patent Document 1. In this technique, as shown in FIG. 4 of the drawing of Patent Document 1, a first engagement member is provided with a first engagement portion, and a parting line between the first interior member and the second interior member from the base of the first engagement portion. A rib extending to the side is provided, and a second engagement portion is provided at the tip of the rib. The first engagement portion is engaged with the first engagement hole of the vehicle body panel, and the second engagement portion is engaged with the second engagement hole at the end of the second interior member and the third engagement of the vehicle body panel. It was in insertion engagement with the hole.
However, according to this structure, since only the first engagement portion and the second engagement portion on the first interior member side engage with the vehicle body panel, the end portion of the second interior member cannot be fixed, and the assembly At that time, the end of the second interior member was easy to escape. When the end portion of the second interior member escapes in this way, the first engagement portion does not stably engage with the second engagement hole or the third engagement hole, and the burden on the rib increases, resulting in deformation of the rib. There is a possibility that the parting line may be shifted due to damage. As a result, the appearance of the mating portion of the first interior member and the second interior member has deteriorated.
As another example of the above-described vehicle interior member mating portion structure, the first engagement portion formed in the first interior member is inserted and fitted into the first hole of the vehicle body panel, and the second engagement of the second interior member. There has been a second technique in which the joint portion is inserted and engaged with the second hole of the vehicle body panel.

JP 2005-324759 A

According to the second conventional technique, the first engagement portion of the first interior member is inserted and fitted into the first hole of the vehicle body panel, and the second engagement portion of the second interior member is inserted into the first of the vehicle body panel. Due to the insertion engagement with the two holes, the parting line between the first interior member and the second interior member may be misaligned due to the misalignment between the first hole and the second hole. As a result, the appearance of the mating portion of the first interior member and the second interior member has deteriorated.
An object of the present invention is to provide a mating portion structure for an interior member of a vehicle that can improve the appearance quality.

The feature of the present invention is that
The first interior member and the second interior member that cover the vehicle body panel in a state of being adjacent to each other,
A long hole is formed in the vehicle body panel in a direction intersecting with a parting line of the first interior member and the second interior member,
An insertion portion to be inserted into the elongated hole is provided on the back side of the end portion of the first interior member,
The cross-sectional shape of the insertion portion in a direction orthogonal to the insertion direction of the insertion portion is set to a U shape that opens in the longitudinal direction of the long hole,
The insertion portion is fitted into the elongated hole;
A first engagement portion provided at an end of the second interior member engages with the elongated hole;
A second engagement portion provided at an end portion of the second interior member is engaged with an end edge of the first interior member in a direction along the parting line. According to this configuration, the following effects can be achieved. (Claim 1)

When the first interior member and the second interior member are assembled to the vehicle body panel, the insertion portion of the first interior member is inserted into the elongated hole of the vehicle body panel and is fitted inside. Then, the first engagement portion of the second interior member is engaged with the elongated hole, and the second engagement portion of the second interior member is engaged with the edge of the first interior member in the direction along the parting line. . Accordingly, the first interior member and the second interior member can be reliably coupled and fixed to each other and can be reliably fixed to the vehicle body panel.
Since the insertion portion is formed in a U-shaped cross section as described above, the pair of opposite side walls of the insertion portion and the back wall connecting the pair of side walls are brought into contact with the inner peripheral edge of the long hole of the vehicle body panel. By making contact, the position of the first interior member can be regulated in three directions with respect to the vehicle body panel.
This makes it difficult for the first interior member to escape during the assembly work, and makes it easier for the operator to perform the assembly work. In addition, the abutment surface of the insertion portion with respect to the inner peripheral edge of the elongated hole can be widened, and the strength of the insertion portion with respect to a force applied in the shearing direction (direction orthogonal to the insertion direction) can be increased.
For example, in a structure in which the insertion portion of the first interior member is inserted and fitted into the first hole of the vehicle body panel, and the first engagement portion of the second interior member is inserted and engaged with the second hole of the vehicle body panel, Due to the misalignment between the first hole and the second hole, the misalignment of the parting line between the first interior member and the second interior member may occur.
On the other hand, according to the above configuration of the present invention, the insertion portion of the first interior member and the first engagement portion of the second interior member are fitted or engaged with the same long hole of the vehicle body panel. Therefore, the above problems do not occur.
Therefore, the dimensional accuracy of the positional relationship between the first interior member and the second interior member with respect to the vehicle body panel can be increased, and the position shift of the parting line can be prevented.
As described above, the parting line can be accurately set at the target position regardless of the dimensional accuracy of the vehicle body panel, and the appearance quality of the joining portion of the first interior member and the second interior member can be improved.
In addition, since the hole into which the insertion portion and the first engagement portion are inserted is a long hole, it is possible to prevent the hole formed in the vehicle body panel from becoming too large and to prevent a reduction in the strength of the vehicle body panel. . (Claim 1)

In the present invention,
The end of the first interior member and the end of the second interior member are overlapped,
An insertion portion provided at an end portion of the first interior member, a first engagement portion provided at an end portion of the second interior member, and a second engagement provided at an end portion of the second interior member. If movement of the long hole in the longitudinal direction with the joint portion is allowed, the following action can be achieved. (Claim 2)

Even if the first interior member and the second interior member contract due to a temperature change, the end of the first interior member and the end of the second interior member can be kept overlapped. Therefore, it is possible to prevent the body panel from being exposed and to prevent the appearance from deteriorating.
Moreover, even if an excessive load is applied to the first interior member and the second interior member, the insertion portion, the first engagement portion, and the second engagement portion move in the longitudinal direction of the elongated hole, The force applied to the first engaging portion and the second engaging portion can be released. As a result, deformation and breakage of the insertion portion, the first engagement portion, and the second engagement portion can be prevented, and the durability of the first interior member and the second interior member can be improved. (Claim 2)

In the present invention,
At the end portion of the first interior member, an overlapping portion where the end portion of the second interior member overlaps is provided,
A vertical wall extends from the tip of the overlapping portion in the direction orthogonal to the parting line to the outer side of the back surface of the overlapping portion,
The tip of the vertical wall on the opposite side of the overlapped part is in contact with the vehicle body panel,
The insertion portion protrudes from the distal end portion of the vertical wall portion to the opposite side of the overlapping portion,
When the second engaging portion of the second interior member is engaged with the end edge of the overlapping portion in the direction along the parting line, the following action can be achieved. (Claim 3)

Since the front end portion of the vertical wall portion is in contact with the vehicle body panel, when the second engagement portion of the second interior member is engaged with the edge of the overlapping portion in the direction along the parting line, It is possible to avoid the overlapping portion from escaping (bending) to the vehicle body panel side.
Thereby, the operation | work which makes the said 2nd engaging part engage with the said edge can be performed easily, and workability | operativity can be improved.
Furthermore, it is possible to prevent the second engaging portion from being damaged by forcibly attaching the second engaging portion to the end edge.
Further, since the insertion portion protrudes from the front end portion of the vertical wall portion to the side opposite to the overlapping portion, the insertion portion can be attached to the vehicle body even if the front end portion of the vertical wall portion is in contact with the vehicle body panel. It can be reliably inserted into the long hole of the panel. (Claim 3)

In the present invention,
A bulging portion having a U-shaped cross section that bulges to the back surface side of the vertical wall portion is formed over the entire length of the vertical wall portion, and the bulging portion extends outward from the distal end portion of the vertical wall portion. The insertion part is formed,
When the U-shaped notch communicating with the space in the bulging portion is formed at the tip of the overlapping portion, the following action can be achieved. (Claim 4)

Since the said bulging part is formed in the back surface side of the vertical wall part over the full length, the rigidity of a vertical wall part can be improved. As a result, even when a force in the abutting direction is applied to the vertical wall portion by the front end portion of the vertical wall portion coming into contact with the vehicle body panel, the deformation of the vertical wall portion can be suppressed, and the vertical wall portion and the overlapping portion are An increase in the angle formed can be suppressed.
Accordingly, when the second engaging portion of the second interior member is engaged with the edge of the overlapping portion in the direction along the parting line, the overlapping portion escapes (bends) to the vehicle body panel side. This can be avoided more reliably.
Further, the bulging portion is formed over the entire length on the back side of the vertical wall portion, and a U-shaped notch communicating with the space in the bulging portion is formed at the tip of the overlapping portion. When molding one interior member with resin, it can be molded without using a complicated slide mold. Therefore, the molding cost can be reduced.
And it can be visually confirmed whether the insertion part is inserted in the long hole of a vehicle body panel through the space in the said bulging part, and a notch. Thereby, assembly | attachment property can be improved. (Claim 4)

The front engaging claw 65 is engaged with the edge 57S of the overlapping portion 57 on the vehicle front side Fr, and the rear engaging claw 65 is engaged with the edge 57S of the overlapping portion 57 on the vehicle rear side Rr.
Then, the third engaging portion 70 is engaged with the engaged portion 81 of the end portion of the quarter lower trim 5 (the end portion of the quarter lower trim front surface portion 52). As a result, the quarter-lower trim 5 and the tail end trim 6 can be reliably coupled and fixed to each other and can be reliably fixed to the vehicle body panel 3.

  Further, the pair of side walls 59S of the insertion portion 59 facing each other and the back wall 59K connecting the pair of side walls 59S are brought into contact with the inner peripheral edge of the elongated hole 11 of the vehicle body panel 3, thereby Thus, the position of the quarter-lower trim 5 can be regulated in three directions.

  This makes it difficult for the quarter lower trim 5 to escape during the assembling work, making it easier for the operator to perform the assembling work. In addition, the contact surface of the insertion portion 59 with respect to the inner peripheral edge of the elongated hole 11 can be widened, and the strength of the insertion portion 59 against the force applied in the shearing direction (direction perpendicular to the insertion direction) can be increased. .

For example, the insertion portion 59 of the quarter lower trim 5 is inserted and fitted into the first hole of the vehicle body panel 3, and the first engagement portion K 1 of the tail end trim 6 is inserted and engaged with the second hole of the vehicle body panel 3. A structure is conceivable. However, in this structure, a position shift of the parting line L between the quarter lower trim 5 and the tail end trim 6 may occur due to the position shift between the first hole and the second hole.
On the other hand, according to the above configuration of the present invention, the insertion portion 59 of the quarter lower trim 5 and the first engagement portion K1 of the tail end trim 6 are fitted or engaged with the same long hole 11. Therefore, the above-mentioned problems do not occur.
Therefore, the dimensional accuracy of the positional relationship between the quarter-lower trim 5 and the tail end trim 6 with respect to the vehicle body panel 3 can be increased, and the position shift of the parting line L can be prevented.

As described above, the parting line L can be accurately set at the target position regardless of the dimensional accuracy of the vehicle body panel 3, and the appearance quality of the mating portion of the quarter-lower trim 5 and the tail end trim 6 can be improved.
Further, since the hole into which the insertion portion 59 and the first engagement portion K1 are inserted is a long hole, it is possible to prevent the hole formed in the vehicle body panel 3 from becoming too large and prevent the strength of the vehicle body panel 3 from being reduced. can do.

(2) As described above, the lower end portion 56K1 of the quarter-lower trim rear wall 56 and the end portion 6A of the tail end trim 6 are overlapped, and the insertion portion 59, the first engagement portion K1, and the second engagement portion K2 are overlapped. The long hole 11 is allowed to move in the longitudinal direction. Therefore, even if the quarter lower trim 5 and the tail end trim 6 contract due to temperature changes, the lower end portion 56K1 of the quarter lower trim rear wall 56 and the end portion 6A of the tail end trim 6 can be kept in an overlapping state. . As a result, it is possible to prevent the vehicle body panel 3 from being exposed and to prevent the appearance from deteriorating.
Even if an excessive load is applied to the quarter lower trim 5 and the tail end trim 6, the insertion portion 59, the first engagement portion K1, and the second engagement portion K2 move in the longitudinal direction of the long hole 11. The force applied to the insertion portion 59, the first engagement portion K1, and the second engagement portion K2 can be released. As a result, deformation and breakage of the insertion portion 59, the first engagement portion K1, and the second engagement portion K2 can be prevented, and the durability of the quarter-lower trim 5 and the tail end trim 6 can be improved.

(3) Since the lower end portion 58K of the vertical wall portion 58 is in contact with the second upper surface portion 31B of the panel lower wall 37, the second engagement portion K2 of the tail end trim 6 extends along the parting line L. When engaging with the edge 57S of the overlapping portion 57 in the direction, it is possible to avoid the overlapping portion 57 escaping (bending) to the second upper surface portion 31B side of the panel lower wall 37.
Thereby, the operation | work which makes the said 2nd engaging part K2 engage with the said edge 57S can be performed easily, and workability | operativity can be improved.
Furthermore, it is possible to prevent the second engaging portion K2 from being damaged due to excessive attachment of the second engaging portion K2 to the end edge 57S.
Further, since the insertion portion 59 protrudes from the lower end portion 58K of the vertical wall portion 58 to the side opposite to the overlapping portion 57, the lower end portion 58K of the vertical wall portion 58 is the second upper surface portion 31B of the panel lower wall 37. Even if it is the structure which contacts, the insertion part 59 can be reliably inserted in the long hole 11 of the said 2nd upper surface part 31B.

(4) Since the bulging portion 58B is formed on the back side of the vertical wall portion 58 over the entire length in the vertical direction, the rigidity of the vertical wall portion 58 can be improved. As a result, the lower end portion 58K of the vertical wall portion 58 is in contact with the second upper surface portion 31B of the panel lower wall 37, so that even if a force in the contact direction is applied to the vertical wall portion 58, deformation of the vertical wall portion 58 is suppressed. It is possible to suppress the increase in the angle formed by the vertical wall portion 58 and the overlapping portion 57.
As a result, when the second engagement portion K2 of the tail end trim 6 is engaged with the edge 57S of the overlap portion 57 in the direction along the parting line L, the overlap portion 57 becomes the first portion of the panel lower wall 37. 2 Escape (bend) to the upper surface portion 31B side can be avoided more reliably.
Further, the bulging portion 58B is formed over the entire length on the back side of the vertical wall portion 58, and a U-shaped notch communicated with the front end portion 57D of the overlapping portion 57 and the space 58C in the bulging portion 58B. Since 57M is formed, when the quarter-lower trim 5 is formed, it can be formed without using a complicated slide mold. Therefore, the molding cost can be reduced. Then, whether or not the insertion portion 59 is inserted into the long hole 11 of the second upper surface portion 31B of the panel lower wall 37 can be visually confirmed through the space 58C and the notch 57M in the bulging portion 58B. Thereby, assembly | attachment property can be improved.
