Description

  The present invention relates to a connecting structure for interior materials for a vehicle such as an upper trim and a lower trim provided on a vehicle interior side.

  An interior material such as an injection molded body of a synthetic resin is provided on the vehicle interior side of an automobile or the like for the purpose of improving the design. For example, an upper trim, a lower trim, and an opening trim are attached to the center pillar (B pillar) of the vehicle body on the vehicle interior side.

  In Patent Document 1, a mounting hole that opens downward is provided in the step portion at the lower end of the upper trim (upper member), and a claw portion (locking claw) is provided near the upper end of the lower trim (lower member). There is disclosed a technique for connecting an upper trim and a lower trim by fitting a hook and a claw. According to this technology, in addition to the cost reduction effect due to the reduction of the required mold at the time of injection molding, it is possible to prevent the upper trim and the lower trim from being displaced in the vertical and horizontal directions.

  Patent Document 2 discloses a technique for connecting an upper trim and a lower trim by providing an engagement protrusion on an upper end of a lower trim (lower garnish) and overlapping the lower end of an upper trim (upper garnish). According to this technique, as described above, the upper trim and the lower trim can be prevented from being displaced in the vertical direction (vertical direction) and the horizontal direction (lateral direction). Furthermore, in this technique, the lower trim is overlapped and fitted from the front of the upper trim, so that it is possible to improve work efficiency without interfering with the passenger compartment floor surface or the like even during installation work.

JP-A-7-304401 Utility Model Registration No. 2606306

  In the technique of the above-mentioned patent document 1, since the claw portion formed at the upper edge of the lower trim (lower member) is inserted into the mounting hole opened downward in the step portion at the lower end of the upper trim, May interfere with the floor. As a result, the shape of the lower trim may be limited, or work efficiency may be reduced.

  In the technique disclosed in Patent Document 2, a seat surface (end surface) parallel to the projecting surface of the upper trim (the surface supported by the two side surfaces fixed to the vehicle body) is formed, and this seat surface is fitted to the engagement protrusion. In order to form a hole, a certain amount of space must be secured as the seating surface, which may limit the application range. In addition, since the shapes of the lower end of the upper trim and the upper end of the lower trim are complicated, the cost may increase, and a technique that achieves the same effect with a simple shape is desired.

  The present invention has been made in view of such a problem, and it is not necessary to set a seating surface at the mating portion of each other, and by superimposing the other vehicle interior material on one vehicle interior material, It is an object of the present invention to provide a connection structure for vehicle interior materials that can be fitted while preventing positional deviation in the vertical and horizontal directions.

  In order to solve the above-described problem, a representative configuration of the present invention includes a first vehicle interior material and a second vehicle including at least two long side surfaces and a projecting surface connecting the longitudinal edges of the two side surfaces. In the connection structure of the vehicle interior material including the vehicle interior material, a notch portion formed at a corner from the side surface to the protruding surface near the end of the first vehicle interior material, and a second vehicle interior material A claw portion projecting inward of the side surface in the vicinity of the end portion, and includes a lower step portion and an upper step portion having different heights in a step shape at a first boundary substantially parallel to the side surface. And the length of the cutout portion extending over the side surface of the first vehicle interior material is equal to or greater than the length of the upper step portion in the lateral direction of the side surface of the second vehicle interior material. The length of the notch extending over the protruding surface of the first vehicle interior material is shorter than the length of the protruding surface of the second vehicle interior material. Characterized in that less than the length of the upper portion in the direction.

  In such a configuration, the notch formed in the corner of the first vehicle interior material reaches the protruding surface (front surface) of the first vehicle interior material. Therefore, by overlapping the second vehicle interior material from the front of the first vehicle interior material, the upper portion of the claw portion of the second vehicle interior material can be inserted into the cutout portion of the first vehicle interior material. Even during the mounting operation, the second vehicle interior material does not interfere with the passenger compartment floor or the like.

  Further, as described above, the length of the cutout portion extending over the protruding surface of the first vehicle interior material is shorter than the length of the upper step portion in the short direction of the protruding surface of the second vehicle interior material. Therefore, when the claw portion is inserted into the cutout portion, only the upper step portion of the claw portion is accommodated in the cutout portion, and the lower step portion is exposed to the outside. After the upper step part of the nail part is almost completely inserted into the notch part along the insertion direction, the nail part is slid in a direction perpendicular to the insertion direction (sliding sideways), so that the lower step part having a stepped height is formed. The upper edge of the notch is brought into contact, and the notch and the claw are fitted.

  From the beginning of inserting the claw part into the notch part, the above operation is performed by pressing the upper step part of the claw part against the upper edge of the notch part and urging the claw part downward and sliding it against the notch part. It is carried out. Thereby, when the upper step portion passes through the notch portion, the lower step portion rises due to elasticity and returns to the original posture, so that the fitting at the first boundary is firmly performed.

  As a result, the first vehicle interior material and the second vehicle interior material can be easily and reliably connected. It is not necessary to set seating surfaces at the mating portions, and the portion where the second vehicle interior material is superimposed on the first vehicle interior material can be reduced, which contributes to cost reduction.

  A characteristic feature of the present invention is that a two-stage attachment operation is possible in which the upper step portion of the claw portion is inserted as described above and then slid in a direction perpendicular to the insertion direction. Therefore, although the second vehicle interior material is inserted from the front of the first vehicle interior material (toward the vehicle side surface), the first vehicle interior material and the second vehicle interior material are Of course, it is connected so as to prevent displacement in the left-right direction (vehicle traveling direction) orthogonal to the insertion direction.

  The upper stage part of the claw part may have an inclined surface that gradually descends at a second boundary substantially parallel to the first boundary. As described above, since the claw portion is inserted while being urged, if an inclined surface that descends is provided on the upper step portion of the claw portion, the upper edge of the notch portion is aligned along the inclined surface during the above sliding. Since it rides on the upper stage smoothly, the upper stage can smoothly pass through the notch.

  The first boundary may be curved along the shape of the side surface of the first vehicle interior material. Thereby, at the time of the above fitting, the entire first boundary abuts against the back side of the side surface of the first vehicle interior material in a stable state, so that a high fitting strength can be ensured. The displacement in the direction can be prevented more reliably.

  It is preferable to further include a rib formed inside the corner portion of the first vehicle interior material and abutting against the upper step portion, and the upper step portion and the rib are in contact with each other in a plane. Thereby, since the upper step side surface of the corner portion side is supported by the rib, it is possible to suppress the wobble of the first vehicle interior material and the second vehicle interior material.

  The thickness of the notch is formed to be greater than the thickness of the upper step, and a guide piece is provided at the corner of the notch to limit the thickness of the notch, and the guide piece is for the first vehicle. When the notch portion of the interior material and the claw portion of the interior material for the second vehicle are fitted, the lower step portion of the claw portion may be sandwiched between the upper edge of the notch portion. Thereby, at the time of the fitting, the lower step portion of the claw portion is sandwiched between the guide piece and the upper edge of the notch portion, so that the claw portion can be prevented from coming off.

  When the notch portion of the first vehicle interior material and the claw portion of the second vehicle interior material are fitted in the vicinity of the corner portion of the first vehicle interior material, the first vehicle interior material comes into contact with the back side of the protruding surface of the second vehicle interior material. It is good to further provide a backing piece. Thereby, it becomes possible to suppress the side surface from being deformed in the left-right direction due to the pressing of the protruding surface of the second vehicle interior material.

  According to the present invention, it is not necessary to set a seating surface at the mating portion of each other, and the vehicle interior material on the other is overlapped with the other vehicle interior material, thereby preventing these vertical and lateral displacements. However, it is possible to provide a connection structure for vehicle interior materials that can be fitted together.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 is a view showing a vehicle compartment to which a connecting structure for vehicle interior materials according to the present embodiment (hereinafter referred to as “connecting structure 100”) is applied. Fig.1 (a) is an external view of the compartment side part, FIG.1 (b) is a figure which shows the state before the assembly | attachment of Fig.1 (a). Moreover, FIG. 2 is AA sectional drawing of Fig.1 (a).

  As shown in FIGS. 1A and 1B, the connecting structure 100 includes, for example, an upper trim that covers a center pillar 104 provided between an opening for a front door and an opening for a rear door in a body panel 102. 110 (first vehicle interior material) and lower trim 122 (second vehicle interior material). That is, the center pillar 104 is covered with the upper trim 110 and the lower trim 122, respectively. A slight gap 108 (see FIG. 3B) through which the webbing 106 passes is formed between the upper trim 110 and the lower trim 122.

  As shown in FIG. 2, the center pillar 104 is constructed by combining an inner panel 104a, a reinforcement 104b, an outer panel 104c, and the like. The upper trim 110 and the lower trim 122 are each fixed to the inner panel 104a of the center pillar 104 by a clip structure or a locking structure (not shown), and are further connected to each other by the connection structure 100 of the present embodiment. .

  The upper half (half circumference) of the flange that forms the edge of the opening for the front door is covered with the opening trim 130. Here, the opening trim 130 has a half circumference. The inclination of the front side of the opening for the front door differs depending on the vehicle type. If the opening trim 130 for the front door, which is created by molding, is formed around the entire circumference, an expensive formwork is formed. This is because the cost must rise. The flange forming the edge of the opening for the rear door is entirely covered by the opening trim 132 (entire circumference).

  In order to attach the vehicle interior material to the center pillar 104, the upper trim 110 is first attached. Next, the opening trim 130 for the front door is installed. Next, the lower trim 122 is attached. Next, an all-around opening trim 132 for the rear door is attached. Here, since the opening trim 130 having a half circumference for the front door does not have a closed loop structure (is not closed), when an external force is applied to the upper trim 110 and the lower trim 122, the front trim is easily deformed to the front door side. Therefore, the connection structure 100 also plays a role for preventing this deformation.

  FIG. 3 is a diagram illustrating a state before the upper trim 110 and the lower trim 122 are fitted and a state after the fitting. FIG. 3A is a diagram showing a state before fitting, and FIG. 3B is a diagram showing a state after fitting. As shown in FIGS. 3A and 3B, the upper trim 110 includes two long side surfaces 110a and 110b and a protruding surface 110c that connects the longitudinal edges of the two side surfaces 110a and 110b. Composed. Similarly, the lower trim 122 includes two long side surfaces 122a and 122b and a protruding surface 122c that connects the longitudinal edges of the two side surfaces 122a and 122b. That is, both the upper trim 110 and the lower trim 122 are members having a U-shaped cross-section that open in the vehicle exterior direction.

  In the vicinity of the lower end (end portion) of the upper trim 110, a cutout portion 112 that is cut out including the corner portion is formed from the side surface 110a on the front door side to the protruding surface 110c. On the other hand, a connecting hole 120 is formed in the protruding surface 110c on the rear door side.

  Near the upper end (end portion) of the lower trim 122, a claw portion 124 that protrudes substantially horizontally from the inside of the side surface 122a on the front door side is formed. The claw portion 124 includes a lower step portion 124a and an upper step portion 124b having different heights in a step shape at a first boundary 126d substantially parallel to the side surface 122a, and is connected to the side surface 122a at the lower step portion 124a. The upper stage portion 124b of the claw portion 124 has an inclined surface 126a that gradually descends at a second boundary 126e substantially parallel to the first boundary 126d. On the other hand, a connecting claw 128 that fits into the connecting hole 120 is formed on the projecting surface 122c on the rear door side.

  The upper trim 110 and the lower trim 122 are connected by fitting the cutout portion 112 and the claw portion 124 (connection structure 100), and the connection hole 120 and the connection claw 128. Here, since a half-circular opening trim 130 is employed on the front door side, the connecting structure 100 is applied to the front door side in order to prevent deformation to the front door side. On the rear door side where the all-around opening trim 132 is employed, a coupling hole 120 and a coupling claw 128, which are general fitting structures, are employed.

  Below, it demonstrates centering on the notch part 112 and the nail | claw part 124 by the side of the front door which are the components of the connection structure 100. FIG. The connecting structure 100 of this embodiment is characterized in that the lower trim 122 is overlapped with the upper trim 110 from the front direction, and the upper step portion 124b is inserted straight into the notch portion 112, and then the nail extends in a direction perpendicular to the insertion direction. That is, the portion 124 (upper step portion 124b) is fitted to the notch portion 112 in a two-step mounting operation of sliding (sliding sideways).

  FIG. 4 is a diagram showing the size of the notch 112 of the upper trim 110 and the claw 124 of the lower trim 122. As shown in FIG. 4, the length D1 of the notch 112 over the side surface 110a of the upper trim 110 is set to be equal to or longer than the length L1 of the upper step portion 124 in the short side direction of the side surface 122a of the lower trim 122 (almost equal is preferable). Can be easily mated). The length D2 of the notch 112 over the protruding surface 110c of the upper trim 110 is set to be shorter than the length L2 of the upper step portion 124b in the short direction of the protruding surface 122c of the lower trim 122. In the present embodiment, the length D2 of the notch 112 over the protruding surface 110c of the upper trim 110 and the length L3 of the inclined surface 126a in the short direction of the protruding surface 122c of the lower trim 122 are set to be approximately equal.

  FIG. 5 is a diagram illustrating a process of connecting the upper trim 110 and the lower trim 122. As shown in FIG. 5A, the upper trim 110 fixed to the center pillar 104 is overlapped with the lower trim 122 from the front direction so that the notch 112 of the upper trim 110 (the upper edge of the notch 112 and the upper edge of the notch 112 will be described later). The claw portion 124 of the lower trim 122 (the inclined surface 126a of the upper step portion 124b) is inserted between the guide piece 114 and the guide piece 114 to be operated. Thereby, the lower trim 122 does not interfere with the passenger compartment floor surface or the like even during the mounting operation.

  Since the length D2 of the notch 112 over the protruding surface 110c is shorter than the length L2 of the upper step portion 124b in the short direction of the protruding surface 122c, the claw portion 124 is inserted into the notch 112 as shown in FIG. Initially, only the upper step portion 124b of the claw portion 124 is accommodated in the notch portion 112, and the lower step portion 124a is exposed to the outside. In particular, since the length D2 of the notch portion 112 is set to be substantially equal to the length L3 of the inclined surface 126a, the upper step portion 124b of the claw portion 124 is inserted into the notch portion 112 along its insertion direction. The upper edge of the notch 112 slides on the inclined surface 126a. The reason that the length L3 of the inclined surface 126a is not made longer than the length D2 of the notch portion 112 is that the length of the inclined surface L3 (the length L2 of the upper step portion 124b) is increased so as to overlap from the front direction. This is because it is difficult to insert the claw portion 124 (the inclined surface 126a of the upper step portion 124b) into the cutout portion 112 (between the upper edge of the cutout portion 112 and a guide piece 114 described later).

  As shown in FIG. 5 (c), after the upper step portion 124b of the claw portion 124 is almost completely inserted into the cutout portion 112 along the insertion direction, the claw portion 124 is slid in a direction perpendicular to the insertion direction (side slip). By doing so, the upper edge of the notch part 112 can be brought into contact with the lower step part 124a having a stepwise different height, and the notch part 112 and the claw part 124 can be fitted.

  FIG. 6 is a diagram showing a process of fitting the notch portion 112 of the upper trim 110 and the claw portion 124 of the lower trim 122. As shown in FIG. 6A, the tip end of the inclined surface 126 a is set to be below the position of the upper edge of the notch 112 of the upper trim 110. Therefore, initially, the tip of the inclined surface 126a can be easily inserted into the notch 112.

  As shown in FIG. 6B, the inclined surface 126a becomes higher as it approaches the root, so that when the upper step portion 124b is slid (sliding sideways), it interferes with the upper edge of the notch portion 112. In order for the upper step portion 124b to pass through the notch portion 112, it is necessary to bend downward. However, since the upper edge of the notch portion 112 smoothly runs on the upper step portion 124b along the inclined surface 126a, as shown in FIG. As such, it can reach the lower stage portion 124a smoothly.

  Here, since the upper step portion 124b was pressed against the upper edge of the notch portion 112 and slid against the notch portion 112 in a state of being biased downward and bent forward, when the upper step portion 124b passes through the notch portion 112, Due to elasticity, the lower step portion 124a is lifted and returns to the original posture. Thus, the fitting is firmly performed at the first boundary 126d.

  In the present embodiment, the first boundary 126 d is curved along the shape of the side surface 110 a of the upper trim 110. When the upper stage portion 124b is restored, the entire first boundary 126d abuts against the back side of the side surface 110a of the upper trim 110 in a stable state, so that a high fitting strength can be ensured, and a lateral displacement is caused. Is reliably prevented.

  FIG. 7 is a diagram showing the shape of the mating portion of the upper trim 110, and FIG. 8 is a diagram showing the shape of the mating portion of the lower trim 122. 7A and FIG. 8A are views seen from the front direction, and FIG. 7B and FIG. 8B are views seen from the back direction.

  As shown in FIGS. 7A and 7B, the thickness X1 of the notch 112 is formed to be thicker than the thickness Y1 of the upper step 124b of the claw 124. A guide piece 114 is provided at an edge of the notch 112 on the corner side so as to limit the thickness X1 of the notch 112. The thickness X2 between the guide piece 114 and the upper edge of the notch 112 is set to such a thickness that the tip of the upper step 124b can be inserted and the thickness of the lower step 124a can be sandwiched.

  Near the corner between the side surface 110a and the projecting surface 110c, a backing piece 116 is provided to support the rear side of the projecting surface 122c of the lower trim 122 when the claw portion 124 is fitted into the notch 112. By supporting the back side of the protruding surface 122c of the lower trim 122 by the backing piece 116, it is possible to prevent the front side surface 122a from being deformed in the opening direction due to the pressing of the protruding surface 122c of the lower trim 122 or the like. it can.

  In order to ensure the flexibility of the backing piece 116, there are gaps above and below the backing piece 116. Accordingly, when the notch 112 and the claw 124 are fitted, even if the backing piece 116 contacts the back side of the projecting surface 122c of the lower trim 122, the backing piece 116 is elastically deformed so that the fitting is easily performed. can do.

  On the inner side of the corner portion between the side surface 110a and the protruding surface 110c, a rib 118 that comes into contact with the upper step portion 124b when fitted is provided. The rib 118 abuts the upper step portion 124b in a plane, and the side surface of the upper step portion 124b on the projecting surface 110c side is supported by the rib 118, and thus has an effect of suppressing mutual wobbling.

  As shown in FIGS. 8 (a) and 8 (b), the corner portion of the side surface tip on the non-projecting surface 122c side of the upper step portion 124b and the corner portion of the side surface tip on the projecting surface 122c side have a curved shape (hereinafter, referred to as “a”) The corner portion of the side surface tip on the non-projecting surface side is referred to as “first curved shape portion 126b”, and the corner portion of the side surface tip on the projecting surface side is referred to as “second curved shape portion 126c”).

  Therefore, by overlapping the lower trim 122 from the front direction with respect to the upper trim 110, the first curved shape portion 126b slides on the surface of the upper trim 110, and the side surface 122a of the lower trim 122 expands in the opening direction (FIG. 5A). ) And (b)). Accordingly, the claw portion 124 (the inclined surface 126a of the upper step portion 124b) of the lower trim 122 can be easily inserted into the notch portion 112 (between the upper edge of the notch portion 112 and the guide piece 114) of the upper trim 110. .

  Further, the second curved shape portion 126c has an upper step portion 124b with respect to the notch portion 112 due to the elastic force of the side surface 122a deformed in the opening direction by sliding in the groove between the upper edge of the notch portion 112 and the guide piece 114. Assist in sliding. That is, in this embodiment, the lower trim 122 is simply overlapped with the upper trim 110 from the front direction to deform the side surface 110a in the opening direction, and the upper step portion 124b slides with respect to the notch portion 112 by its elastic force ( Side slip). Therefore, the notch part 112 and the claw part 124 can be fitted very suitably.

  FIG. 9 is a cross-sectional view taken along line BB and CC in FIG. 9A is a cross-sectional view taken along the line BB in FIG. 5C, and FIG. 9B is a cross-sectional view taken along the line CC in FIG. 5C. As shown in FIG. 9A, in this embodiment, when the notch 112 and the claw 124 are fitted, the lower step 124a of the claw 124 is between the guide piece 114 and the upper edge of the notch 112. It is comprised so that it may be pinched. As a result, as shown in FIG. 9B, even if the thickness X1 of the cutout portion 112 is formed to be thicker than the thickness Y1 of the upper step portion 124b, the claw portion 124 can be reliably prevented from coming off.

  As described above, according to the configuration described above, although the lower trim 122 is inserted from the front of the upper trim 110 (toward the vehicle side surface), the upper trim 110 and the lower trim 122 are orthogonal to the insertion direction as well as the vertical direction. Positional displacement in the left-right direction (vehicle traveling direction) is also connected so as to prevent it.

  In particular, both the lower trim 122 and the lower trim 122 can be connected to each other by simply setting the notch 112 and the claw 124 without complicating the shapes of the upper trim 110 and the lower trim 122. Since only the notch portion 112 is provided in the upper trim 110 and the claw portion 124 is provided in the lower trim 122, the overlapping portion can be suppressed as much as possible, and the weight can be reduced.

  Further, the claw portion 124 is formed in the short direction of the projecting surface 122c of the lower trim 122, and the upper step portion 124b is only raised in a substantially parallel direction along the side surface 122a. Therefore, when the lower trim 122 is molded, the die is removed. The upper step portion 124b can be provided along the direction, and a complicated mold structure such as a slide mold is not used. Therefore, it can be realized at a low cost.

  In the above embodiment, the connection structure 100 is applied to the front side of the upper trim 110 and the lower trim 122, but may be applied to the rear side or may be adopted on both sides. Further, for example, the upper stage portion 124b does not necessarily have to protrude upward, and may protrude upward. Contrary to this embodiment, the configuration in which the claw portion 124 is provided in the upper trim 110 and the notch portion 112 is provided in the lower trim 122 is not excluded.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
