Description

  The present invention relates to an adhesion structure between members of a cab.

  In a large truck or the like, for example, above the cab body having left and right cab side surfaces defining both sides in the vehicle width direction of the vehicle compartment, from the ceiling surface portion of the vehicle compartment and the edges of both sides in the vehicle width direction of the ceiling surface portion. A high roof vehicle is known in which a high roof panel having left and right extension surface portions that extend downward and continuous to the left and right cab side portions is attached, and the cabin is extended above the upper end of the cab side portion of the cab body. Yes. In this type of vehicle, for example, the high roof panel is formed of a resin material or the like, and the left and right extension surface portions are reinforced by a roof side force that extends in the vertical direction along the inner surface in the vehicle width direction of each extension surface portion. A roof side drain force is bonded to the inner surface of the extension surface portion on the inner side in the vehicle width direction.

  In Patent Document 1, side end portions on both sides in the vehicle width direction of a roof panel provided on a roof portion of a vehicle body are bonded to a pair of left and right roof side rails extending in the front-rear direction of the vehicle across the upper end portions of each pillar. An adhesive structure is described. The roof panel is formed of a resin material or the like, and has a flange portion formed in a step shape lower than other portions at left and right side end portions on both sides in the vehicle width direction, and the left and right flange portions extend in the front-rear direction. It is attached to the roof side rail in a state where it is placed on the upper surface of the flange portion formed at the upper end portion of the side rail. Between the lower surface of the flange portion of the roof panel and the upper surface of the flange portion of the roof side rail, a plurality of spacers for positioning the height of the roof panel with respect to the vehicle body are dispersed and sandwiched in the front-rear direction. On the outer side in the width direction, an adhesive that also serves as a sealant seals between the upper and lower flange portions. The flange portion of the roof panel is fixed to the flange portion of the roof side rail with a plurality of bolts in order to position the roof panel until the adhesive is cured. The bolt is inserted from above into the through hole of the spacer sandwiched between the upper and lower flange portions.

JP 2012-1142 A

  In the adhesive structure described in Patent Document 1, since the upper surface of the flange portion of the roof side rail extends in the front-rear direction of the vehicle and is disposed substantially horizontally, the spacer placed on the upper surface of the flange portion of the roof side rail is It is sandwiched between the upper and lower flange portions while remaining stationary on the upper surface of the flange portion.

  On the other hand, for example, in a high roof panel mounted on a high roof car, when the rain force is bonded to the inner surface in the vehicle width direction of the left and right extension surfaces (panel material), the rain force extends in the vertical direction. A spacer cannot be placed on any of the adhesion surfaces of the outer surface in the vehicle width direction of the force and the inner surface of the extension surface portion in the vehicle width direction, and the extension surface portion and the rain until the adhesive is cured. It is difficult to maintain the gap between the force and the desired width by the spacer.

  An object of the present invention is to provide an adhesive structure capable of stably maintaining the width of a gap in which an adhesive before curing is interposed, regardless of the panel material and the posture of the reinforcement.

  In order to solve the above-described problems, the present invention provides a resin-made panel material that constitutes a cab, and a metal reinforcement that extends in a predetermined direction along the surface of the panel material is fixed by adhesion. An adhesion structure between members of a cab to be reinforced includes an adhesive layer interposed between a panel material and a reinforcement, and a coupling member fixed to the reinforcement.

  Reinforce has a facing surface that faces the surface of the panel material. The facing surface includes a surface to be bonded and a surface to be bonded that continuously extends from the surface to be bonded in the predetermined direction. The coupling members are a pair of joint plates that are joined in a state of surface contact with the surface to be joined of the reinforcement, and a pair of joint members that protrude from both end edges of the joint plate in the direction crossing the predetermined direction and are joined to the panel member. The joint portion is integrally formed, and is fixed to the reinforcement by joining the joining plate portion and the joined surface. When the pair of coupling portions of the coupling member are coupled to the panel material, the joining plate portion of the coupling member is disposed between the opposing surface of the reinforcement and the surface of the panel material. A gap is formed between the bonding surface of the force and the bonding plate portion. The adhesive layer is interposed between the surface of the panel material and the bonded surface of the reinforcement within the gap, and bonds the reinforcement and the panel material.

  For example, above a cab body having left and right cab side surfaces that define both sides in the vehicle width direction of the passenger compartment, a ceiling surface portion that forms a ceiling surface of the passenger compartment, and downward from edges of both sides of the ceiling surface portion in the vehicle width direction In a cab of a high roof vehicle in which a high roof panel integrally extending with left and right extension side portions extending to the left and right cab side portions is attached, and the cabin is extended upward from the upper end of the cab side portion by the high roof panel. When the roof side drain force (reinforce) that extends in the vertical direction on the vehicle width direction inside of the extension surface portion (panel material) is fixed to the extension surface portion by bonding, the adhesive layer is between the extension surface portion and the roof side drain force. The interposition and the coupling member are fixed to the roof side drain force. The roof side drain force has an outer side (opposite side) in the vehicle width direction opposite to the inner side (front side) in the vehicle width direction of the extended surface portion. The outer side of the roof side drain force is joined to the joined surface and the joined surface. And a surface to be bonded that continuously extends from the surface to at least one of the upper side and the lower side. The coupling member includes a flat joint plate portion joined in a state of surface contact with the joined surface of the roof side drain force, and a pair of front and rear joints projecting forward and rearward from the joint plate portion and joined to the extension surface portion. And is fixed to the roof side drain force by joining the joining plate part and the joined surface. In a coupled state where the front and rear coupling portions of the coupling member are coupled to the extension surface portion, the joining plate portion of the coupling member is disposed or sandwiched between the outer surface of the roof side force and the inner surface of the extension surface portion. A gap is formed by the joining plate portion between the inner surface and the adherend surface of the roof side drain force. The adhesive layer is interposed between the inner surface of the extension surface portion and the adherend surface of the roof side force in the gap, and bonds the roof side force and the extension surface portion.

  In the above configuration, a gap is formed between the surface of the panel material and the surface to which the reinforcement is bonded in a bonded state in which a pair of coupling portions of the coupling member fixed to the metal reinforcement is coupled to the resin panel material. Is formed. Since this gap is formed by the joining plate portion of the joining member joined to the panel material, as long as the joined state between the panel material and the joining member is maintained, the width of the gap (the surface of the panel material and the coverage of the reinforcement) The distance from the bonding surface is maintained at a predetermined width. Therefore, regardless of the panel material and the posture of the reinforcement, the gap can be stably held at a predetermined width until the adhesive (adhesive layer before curing) interposed in the gap is cured. An adhesive layer having a predetermined thickness can be uniformly formed in a predetermined direction. Also, in order to secure a gap between the surface of the panel material and the adherend surface of the reinforcement, it is not necessary to insert a jig such as a spacer between the panel material and the reinforcement. Work such as removal of the jig after the agent has hardened becomes unnecessary, and the work can be simplified.

  The surface of the panel material may have a general surface and an adhesive surface that protrudes from the general surface and opposes the adhesion surface of the reinforcement. The joining plate portion of the coupling member is disposed between the opposing surface of the reinforcement and the general surface of the panel material, and the gap is formed between the adhesion surface and the adherend surface.

  In the above configuration, the distance between the general surface of the panel material and the opposing surface of the reinforcement is a length according to the thickness of the joining plate portion of the coupling member, and the distance between the bonding surface of the panel material and the adhesion surface of the reinforcement The distance (gap width) is shorter than the length corresponding to the thickness of the joining plate portion of the coupling member by the protruding height of the bonding surface (the protruding height from the general surface) (the gap width becomes thinner). ). Therefore, by appropriately changing the protruding height of the bonding surface, the width of the gap can be set to a desired arbitrary width that is narrower than the width corresponding to the plate thickness of the bonded plate portion. In addition, since the adhesive surface protrudes from the general surface, when applying adhesive to the adhesive surface of the panel material in a state where the reinforcement is detached from the panel material, the operator can easily locate the adhesive surface by visual or tactile sense. Can be recognized, and work efficiency can be improved.

  According to the present invention, it is possible to stably maintain the width of the gap in which the adhesive before curing is interposed, regardless of the panel material and the posture of the reinforcement.

As shown in FIG. 2, the roof side drain force 16 a extends in the vertical direction (predetermined direction) along the inner surface (surface) 24 of the extended side surface portion 19 of the high roof panel 15 on the vehicle compartment 4 side, and adheres to the inner surface 24. Fixed.

  As shown in FIG. 2 and FIGS. 3A and 3B, the roof side drain force 16a includes a front flange portion 25, a rear flange portion 26, a rear end edge of the flange portion 25, and a flange portion. 26, and has a convex portion 27 that protrudes inward in the vehicle width direction and is formed in a so-called hat shape.

  In the roof side drain force 16a, as shown in FIGS. 2 and 3B, the coupling member 29 is fixed to the joined surfaces 28a of the flange portions 25 and 26. The joining member 29 includes a flat joining plate portion 30 that is joined in surface contact with the joined surface 28a of the roof side drain force 16a, and a vertical direction in which the roof side drain force 16a extends from both ends of the joining plate portion 30. A pair of coupling portions 31a and 31b that project in the front-rear direction substantially orthogonal to (predetermined direction) and are coupled to the inner surface 24 of the high roof panel 15 are integrally provided. The joining member 29 is formed by press-molding a metal flat plate material, and the joining plate portion 30 is joined to the joined surface 28a by welding or the like, and is fixed to the roof side drain force 16a. The coupling portion 31a has a bolt insertion hole 32 that bends the front end edge of the joining plate portion 30 inward in the vehicle width direction and extends forward, and penetrates in the vehicle width direction. The coupling portion 31b has a bolt insertion hole 33 that bends the rear end edge of the joining plate portion 30 inward in the vehicle width direction and extends rearward and penetrates in the vehicle width direction. The coupling member 29 can be provided at a plurality of locations in the vertical direction of the flange portions 25 and 26.

  As shown in FIG. 3B, the high roof panel 15 has a pair of frustoconical bosses 34 and 35 protruding inward in the vehicle width direction from the inner surface 24 of the extended side surface portion 19. The bosses 34 and 35 are formed integrally with the extended side surface portion 19, and have end surfaces with which the outer surfaces in the vehicle width direction of the pair of coupling portions 31 a and 31 b of the coupling member 29 abut, respectively. Bolt fastening holes 38 and 39 for fastening bolts 36 and 37 respectively passed through the bolt insertion holes 32 and 33 of the pair of coupling portions 31a and 31b are formed.

  In the coupling member 29 fixed to the roof side drain force 16a, a pair of coupling portions 31a and 31b are coupled to the bosses 34 and 35 of the extended side surface portion 19 by fastening bolts 36 and 37, respectively. The joining plate portion 30 of the coupling member 29 is disposed between the facing surface 28 of the roof side drain force 16 a and the inner surface 24 of the extended side surface portion 19. Specifically, the joining plate portion 30 of the coupling member 29 is sandwiched between the facing surface 28 of the roof side force 16a and the inner surface 24 of the extended side surface portion 19 in surface contact with each other. Therefore, a gap S is formed by the joining plate portion 30 between the inner surface 24 of the extended side surface portion 19 of the high roof panel 15 and the adherend surface 28b of the roof side force 16a.

  Here, as shown in FIGS. 3A and 3B, the inner surface 24 of the extended side surface portion 19 of the high roof panel 15 protrudes inward in the vehicle width direction from the flat general surface 40 and the general surface 40. It has a flat adhesive surface 41 facing the adherend surface 28b of the side drain force 16a. The bonding surface 41 is formed along a thick step 42 that protrudes inward in the vehicle width direction from the general surface 40, and the bonding surface 41 and the general surface 40 are continuous via the step 42.

  The joining plate portion 30 of the coupling member 29 is disposed between the general surface 40 of the high roof panel 15 and the facing surface 28 of the roof side drain force 16a, and the bonding surface 41 of the high roof panel 15 and the roof side drain force 16a are bonded. A gap S is formed between the surface 28b. The gap S continuously extends upward from the bonding plate portion 30 of the coupling member 29, and an adhesive layer 43 in which the adhesive is cured is interposed in the gap S. The bonding layer 43 is bonded to the bonding surface 41 and the bonded surface 28 b, and the lower end of the bonding layer 43 reaches the bonding plate part 30.

  The distance between the general surface 40 of the high roof panel 15 and the facing surface 28 of the roof side force 16a is substantially the same as the thickness of the joining plate portion 30 of the coupling member 29, and the adhesive surface 41 of the high roof panel 15 and the roof side The distance between the reinforcement 16 a and the adherend surface 28 b (the width of the gap S) is shorter than the thickness of the joining plate portion 30 of the coupling member 29 by the height of the stepped portion 42.

  As an assembly method of the adhesive structure of the present embodiment, for example, a pair of coupling members 29 fixed to the roof side drain force 16a in a state where an adhesive is applied along the adhesive surface 41 of the inner surface 24 of the high roof panel 15. The connecting portions 31a and 31b and the end surfaces of the bosses 34 and 35 on the inner surface 24 are brought into contact with each other. At this time, the adhesive contacts the adherend surface 28b of the roof side drain force 16a. Subsequently, the bolts 36 and 37 are passed through the bolt insertion holes 32 and 33 of the pair of coupling portions 31 a and 31 b of the coupling member 29, and the tip ends of the bolts 36 and 37 are inserted into the bolt fastening holes 38 and 39 of the bosses 34 and 35. Let them conclude. Accordingly, the high roof panel 15 and the roof side drain force 16a are fixed to each other via the coupling member 29, and the coupling member is provided between the adhesion surface 41 of the high roof panel 15 and the adherend surface 28b of the roof side drain force 16a. By 29, the clearance gap S which an adhesive agent interposes is formed. The adhesive interposed in the gap S hardens to bond the inner surface 24 of the high roof panel 15 and the roof side drain force 16a.

  In the present embodiment, the pair of coupling portions 31a and 31b of the coupling member 29 fixed to the metal roof reinforcement 16a is coupled to the resin-made high roof panel 15, and the inner surface 24 of the high roof panel 15 and the roof A gap S is formed between the opposing surface 28 of the reinforcement 16a. Since the gap S is formed by the joining plate portion 30 of the coupling member 29 coupled to the high roof panel 15, as long as the coupling state of the high roof panel 15 and the coupling member 29 is maintained, the width of the gap S, that is, the high roof The distance between the bonding surface 41 of the inner surface 24 of the panel 15 and the bonded surface 28b of the roof reinforcement 16a is maintained at a predetermined width. Therefore, regardless of the attitude of the high roof panel 15 and the roof reinforcement 16a, the gap S can be stably held at a predetermined width until the adhesive interposed in the gap S is cured. The adhesive layer 43 having a thickness can be uniformly formed in a predetermined direction. In addition, in order to secure the clearance S, it is not necessary to insert a jig such as a spacer between the inner surface 24 of the high roof panel 15 and the opposed surface 28 of the roof reinforcement 16a. After that, the work such as removing the jig is not necessary, and the work can be simplified.

  In the present embodiment, the distance between the general surface 40 of the inner surface 24 of the high roof panel 15 and the facing surface 28 of the roof reinforcement 16a is a length corresponding to the thickness of the bonding plate portion 30 of the coupling member 29, that is, the bonding The distance between the bonding surface 41 of the inner surface 24 of the high roof panel 15 and the bonded surface 28b of the roof reinforcement 16a (the width of the gap S) is approximately the same as the thickness of the plate portion 30. It is shorter than the thickness of 30 by the protruding height of the bonding surface 41 (the height of the protruding step 42 protruding from the general surface 40) (the width of the gap S is reduced). Therefore, by appropriately changing the protruding height of the bonding surface 41, the width of the gap S can be set to a desired arbitrary width that is narrower than the width of the thickness of the bonding plate portion 30. Further, since the adhesive surface 41 protrudes from the general surface 40, when the adhesive is applied to the adhesive surface 41 of the high roof panel 15 with the roof reinforcement 16a detached from the inner surface 24 of the high roof panel 15, the operator cannot visually Further, it is possible to easily recognize the location of the adhesive surface 41 by tactile sense, and it is possible to improve work efficiency.

  In the present embodiment, the joining plate portion 30 of the coupling member 29 is sandwiched between the facing surface 28 of the roof side drain force 16a and the inner surface 24 of the high roof panel 15, so that the joining plate portion The dimensional accuracy of the width of the gap S can be improved as compared with the case where 30 is arranged away from the inner surface 24 of the high roof panel 15. The connecting member 29 can be disposed in a state where the joining plate portion 30 is separated from the inner surface 24 of the high roof panel 15 by being firmly fixed to the inner surface 24 of the high roof panel 15.

  In the present embodiment, the bosses 34 and 35 are raised from the inner surface 24 of the high roof panel 15, and are passed through the bolt insertion holes 32 and 33 of the coupling member 29 through the bolt fastening holes 38 and 39 formed in the bosses 34 and 35. Bolts 36 and 37 are fastened. For this reason, the thickness of the extended side surface portion 19 of the high roof panel 15 can be supplemented by the height of the bosses 34, 34, and the coupling member 29 can be firmly attached to the high roof panel 15. Therefore, a fixing force for fixing the inner surface 24 of the high roof panel 15 and the roof side drain force 16a can be reliably ensured regardless of the thickness of the extended side surface portion 19.
