Description

  The present invention relates to a vehicle body joint structure using an adhesive and a spot welded portion for joining three plate-like members constituting a vehicle body, and a method for assembling the vehicle body joint structure.

  As a vehicle body joining structure, there is one in which both joining end portions of two plate-like members are integrated using an adhesive and spot welding (spot welding) or the like. In such a vehicle body joining structure, since the adhesive is in a state of protruding from the end surfaces (outer edges) of both joint ends during joining, various devices for preventing the adhesive from protruding have been proposed. . Specifically, in Patent Document 1, a bulging portion is formed at one of the joining end portions to be integrated so as to be separated from the other joining end portion, and the bulging portion inner surface is formed. A gap space that is closed with respect to the outer edges of both joint ends and opened with respect to the inner edge is formed between the other joint ends and the gap is filled with an adhesive. . According to this, it is possible to prevent the adhesive overflowing from the gap space from protruding from the inner edges of both joint ends, and to prevent the adhesive from protruding outward from the outer edges of both joint ends. Further, in Patent Document 2, a bulging portion is formed at one joining end portion of both joining end portions to be integrated so as to be separated from the other joining end portion, and the bulging portion at the one joining end portion is formed. The other part (convex part) is brought into contact with the other joining end, and the gap space between the inner surface of the bulging part and the other joining end is filled with the adhesive. According to this, the gap space can be kept constant by contact between the other joining end portion and a portion (convex portion) other than the bulging portion at one joining end portion, and the outside of both joining end portions. The adhesive can be prevented from protruding outward from the edge. Furthermore, Patent Document 3 shows a structure in which a concave portion that is one step lower than the other portion is formed on the inner surface (joint surface) of one of the joint end portions to be integrated. According to this, at the time of joining of both joining end parts, the concave portion can be made to function positively as an adhesive receiving space, and thereby, the protrusion of the adhesive can be suppressed.

  By the way, as a vehicle body joining structure, there is one in which the joining end portions of the two plate-like members are not integrated, but the joining end portions of the three plate-like members are integrated in an overlapped state. Even in this case, if the techniques of the above-mentioned patent documents 1 to 3 are applied, it is possible to increase the integrated strength of the joint end portion by adhesive and spot welding and to prevent the adhesive from protruding. Can do.

JP 2006-21362 A Japanese Patent Laid-Open No. 2004-082136 JP 2007-071260 A

  However, in the case where the joint ends of the three plate members are integrated, a welding current sufficient to ensure the welding quality of spot welding must be passed. In such a situation, it is required to apply Patent Document 1 or 2 to prevent the adhesive from sticking out of the three joint end portions. When the bulging part which bulges outwards is formed on the two, the substantial thickness of the joint end three is considerably increased.

  In this case, with respect to preventing the adhesive from protruding, Patent Document 3 is applied, and among the three joint end portions, the concave portion is formed on both sides in the thickness direction (both joint surfaces) of the joint end portion disposed in the middle. May be formed as an adhesive receiving space. However, a considerable processing burden is involved in forming concave portions on both joint surfaces.

  The present invention has been made in view of the above circumstances, and a first technical problem thereof is a case where the joining end portions of the three plate-like members are integrated by using an adhesive and spot welding. However, an object of the present invention is to provide a vehicle body joining structure that can easily prevent the adhesive from protruding without increasing the thickness of the entire joining end portion of the three plate-like members.

  A second technical problem is to provide a method for assembling a vehicle body joint structure for manufacturing the vehicle body joint structure.

In order to achieve the first technical problem, in the present invention (the invention according to claim 1),
As the three plate-like members constituting the vehicle body, first to third plate-like members are provided, and the joining end portion of the first to third plate-like members uses an adhesive and a spot welded portion. And a vehicle body joint structure in which the joint end of the third plate member is positioned between the joint end of the first plate member and the joint end of the second plate member. Because
The bonding end of the third plate-shaped member is bonded to at least one of the bonding end of the first plate-shaped member or the bonding end of the second plate-shaped member by the adhesive, All joining end portions of the first to third plate-like members are fixed by the spot welding portion,
Between the joint end portions of the first and second plate-like members, the end face of the joint end portion of the third plate-like member is more than the end face of the joint end portions of the first and second plate-like members. It is set as the structure by which the adhesive agent storage space is formed by retracting to the welding part side. Preferred embodiments of the first aspect are as described in the second to fifth aspects.

In order to achieve the second technical problem, in the present invention (the invention according to claim 6),
By using an adhesive and a spot welded portion as the joining end of the first to third plate-like members, between the joining end of the first plate-like member and the joining end of the second plate-like member. In the assembling method of the vehicle body joint structure in which the joint ends of the third plate-like members are integrated in a state where
As the second plate-like member, a member made thinner than the thickness of the first and third plate-like members is prepared, and as the third plate-like member, the joint end portion has a notch-like recess. Prepare what you have,
First, the bonding end of the first plate member and the bonding end of the third plate member are bonded using an adhesive,
Next, the joint end of the second plate-shaped member is overlapped with the joint end of the third plate-shaped member, and the notch-shaped recess is formed between the joint end portions of the first and second plate-shaped members. Position so that
Next, spot welding is performed on all the joining end portions of the first to third plate-like members in order to form the spot welded portion in the vicinity of the notch-shaped recess.

  According to the invention which concerns on Claim 1, even when the joining edge part of the 1st-3rd plate-shaped member is integrated using an adhesive agent and a spot welding part, both joining of the 1st and 2nd plate-shaped member Between the end portions, the end surface of the joining end portion of the third plate-like member is retracted closer to the spot welded portion than the end surfaces of both joining end portions of the first and second plate-like members, thereby forming an adhesive reservoir space. Therefore, when the first to third plate-like members are integrated, the adhesive used to integrate the joining end portions can be stored in the adhesive reservoir space, and the adhesive is external. It can be prevented from sticking out.

  In this case, in order to form an adhesive reservoir space, the end face of the joint end of the third plate member is simply retracted to the spot welded portion between the joint ends of the first and second plate members. Therefore, there is no change in the thickness of the entire joining end portion of the first to third plate-like members, and the joining end as in the case where the bulging portion is formed at the joining end portion of the first and second plate-like members. There is no increase in the substantial thickness of the entire part.

  Moreover, the adhesive reservoir space can be formed by a configuration in which the end surfaces of the joint end portions of the third plate-like member are retracted with respect to the end surfaces of both joint end portions of the first and second plate-like members. Heavy processing such as processing an adhesive receiving space portion such as a concave portion on both thickness direction surfaces (both joint surfaces) of the three plate-like members is not necessary.

  For this reason, even if it is a case where the joining edge part of three plate-shaped members is integrated by using an adhesive agent and spot welding, the protrusion of an adhesive agent is joined and the joining edge part of the three plate-like member is carried out. This can be easily prevented without increasing the overall thickness.

  According to the invention which concerns on Claim 2, in connection with the 1st-3rd plate-shaped member being an elongate member, the joining edge part of a 1st-3rd plate-shaped member is the 1st-3rd plate-shaped member. Since a plurality of spot welds are provided at the joining end portions of the first to third plate-like members at intervals in the extending direction, the first to third elongated portions are provided. The joining end portion of the plate-like member can be integrated not only by the adhesive but also by a plurality of spot welds, and the integrated strength can be increased.

  According to the invention which concerns on Claim 3, the end surface of the junction end part in a 3rd plate-shaped member is each partly more than the end surface of the junction end part in a 1st and 2nd plate-shaped member for every point welding part. Since a plurality of adhesive reservoir spaces are formed by retracting to the spot welded portion side, the adhesive that flows along with the spot welding for forming each spot welded portion is transferred to each adhesive reservoir space. Even if each plate-like member is long, it is possible to accurately prevent the adhesive from protruding to the outside.

  According to the invention which concerns on Claim 4, the thickness of the 2nd plate-shaped member is made thinner than the thickness of the 1st and 3rd plate-shaped member, and the junction edge part of the 1st plate-shaped member and the 3rd plate-shaped member Since only the joining end portion of the second plate-like member is bonded by an adhesive, the joining end portion of the second plate-like member is fixed only to the joining end portions of the first and third plate-like members by the spot welding portion. Integration of both joint ends of the first and third plate-like members constituting a substantial strength member (specifically, a closed cross-section structure) is performed by using an adhesive and a spot welded portion, and the integrated strength is increased. On the other hand, regarding the attachment of the second plate-like member that does not contribute much to the strength, the amount of adhesive used can be reduced only as a spot weld.

  Further, the thickness of the second plate member is made thinner than the thickness of the first and third plate members in order to meet the demand for thinning the thickness of the entire joining end portion in the first to third plate members. And the thickness of the whole joining edge part in a 1st-3rd plate-shaped member can be made thin.

  According to the invention of claim 5, the first plate-like member is a side sill inner panel, the second plate-like member is a side sill outer panel, the third plate-like member is a side sill reinforcement, Since the joint end portion of the three plate-shaped members faces the side door opening of the vehicle body, the vehicle body joint structure is applied to the joint end portion of the side sill, while preventing the adhesive from protruding, Occurrence of the opening phenomenon at each joint end can be reliably prevented.

  According to the invention which concerns on Claim 6, the joining edge part of this 1st plate-shaped member and this 2nd are used for the joining edge part of the 1st-3rd plate-shaped member using an adhesive agent and a spot welding part. In the assembling method of the vehicle body joint structure in which the joint end of the third plate-like member is positioned between the joint end of the plate-like member, the first and the second plate-like members are the first and the second plate-like members. While preparing what was made thinner than the thickness of a 3rd plate-shaped member, as the said 3rd plate-shaped member, the thing in which the joining edge part has a notch-shaped recess is prepared, First, said 1st plate The joining end portion of the plate-like member and the joining end portion of the third plate-like member are bonded using an adhesive, and then the joining end portion of the second plate-like member is joined to the joining end of the third plate-like member. Is positioned so that the notch-shaped recess is located between both joint ends of the first and second plate-like members, Since spot welding is performed to form the spot welded portion in the vicinity of the notch-shaped recess with respect to all the joining end portions of the first to third plate-like members, Such a vehicle body joint structure can be specifically assembled.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a side sill structure to which the vehicle body joining structure according to the embodiment is applied. In FIG. 1, reference numeral 1 denotes side sills arranged on both sides in the vehicle width direction (only one is shown in FIG. 1), and each side sill 1 extends in the longitudinal direction of the vehicle body. The upper part of each side sill 1 defines the lower side of the side door opening 2, and the floor panel 3 is joined so as to straddle the inner side surface of the left and right side sills 1.

  As shown in FIG. 1, the side sill 1 includes a side sill inner panel (hereinafter referred to as an inner panel) 4 as a first plate member and a side sill as a second plate member so as to form a closed cross-section structural member. An outer panel (hereinafter referred to as “outer panel”) 5 and a side sill reinforcement (hereinafter referred to as “reinforcement”) 6 as a third plate-like member are configured.

  The inner panel 4 is formed so as to swell inward in the vehicle width direction over substantially the entire length in the vehicle longitudinal direction. An upper flange portion 4a as a joining end portion is provided on the upper portion of the inner panel 4 so as to stand up while facing the plate surface in the vehicle width direction. The upper flange portion 4a It is extended in the longitudinal direction of the vehicle body while maintaining the state substantially. Similarly, a lower flange portion 4b as a joining end portion is provided at the lower portion of the inner panel 4 so as to stand downward (hang down) with its plate surface facing the vehicle width direction. The flange portion 4b is extended in the longitudinal direction of the vehicle body while substantially maintaining the standing state.

  The outer panel 5 is formed so as to swell outward in the vehicle width direction over substantially the entire length in the vehicle longitudinal direction. An upper flange portion 5a (joint end portion) is provided at the upper portion of the outer panel 5 so as to stand upward with its plate surface facing the vehicle width direction, corresponding to the upper flange portion 4a of the inner panel 4. The upper flange portion 5a is extended in the longitudinal direction of the vehicle body while substantially maintaining the standing state. Similarly, a lower flange portion 5b (joint end portion) is provided at the lower portion of the outer panel 5 so as to stand downward (hang down) with its plate surface facing the vehicle width direction. The portion 5b is extended in the longitudinal direction of the vehicle body while substantially maintaining its standing state. The upper flange portion 5a of the outer panel 5 is integrated with the upper flange portion 4a of the inner panel 4 in an overlapped state, and the lower flange portion 5b of the outer panel 5 is integrated with the lower flange portion 4b of the inner panel 4. On the other hand, the inner panel 4 and the outer panel 5 are integrated in an overlapped state, thereby forming a closed section 7.

  The reinforcement 6 is disposed in a closed section 7 formed by the inner panel 4 and the outer panel 5 and extends in the longitudinal direction of the vehicle body. Like the outer panel 5, the reinforcement 6 is formed so as to swell outward in the vehicle width direction over substantially the entire length in the vehicle front-rear direction, and its plate surface is shaped close to the inner surface of the outer panel 5. . An upper flange portion 6a (joint end portion) corresponding to the flange portions 4a and 4b (5a and 5b) of the inner panel 4 and the outer panel 5 is disposed on the upper portion of the reinforcement 6 in the vehicle width direction. The upper flange portion 6a is extended in the longitudinal direction of the vehicle body while substantially maintaining the standing state. Similarly, a lower flange portion 6b (joint end portion) is provided at the lower portion of the reinforcement 6 so as to stand downward (hang down) with its plate surface facing the vehicle width direction. The side flange portion 6b is extended in the longitudinal direction of the vehicle body while substantially maintaining the standing state. As shown in FIGS. 1 and 3, a plurality of notched recesses 8 are formed in each of the upper flange portion 6 a and the lower flange portion 6 b of the reinforcement 6. Each notch-shaped recess 8 is formed by retracting the end surfaces 6aa (6bb) of the upper flange portion 6a and the lower flange portion 6b inward (in FIG. 3, the notch shape of the upper flange portion 6a). Only the recess 8 is shown), and each notch-like recess 8 is opened not only in the thickness direction of the flange portion 6a (6b) but also upward. In the present embodiment, each notch-shaped recess 8 has a shape that expands in the extending direction of the flange portion 6a (6b) toward the rising end side of the flange portion 6a (6b).

  1 and 2, the reinforcement 6 has an upper flange portion 6a sandwiched between an upper flange portion 5a of the outer panel 5 and an upper flange portion 4a of the inner panel 4, and a lower flange portion 6b thereof. It is sandwiched between the lower flange portion 5 b of the outer panel 5 and the lower flange portion 4 b of the inner panel 4. At this time, the end surfaces 4aa, 5aa, 6aa (4bb, 5bb, 6bb) of the flange portions 4a, 5a, 6a (4b, 5b, 6b) of the inner panel 4, the outer panel 5 and the reinforcement 6 are the reinforcement 6. The upper flange portion 6a (6b) is substantially aligned except for the notch-shaped recess 8 portion. Accordingly, there is a reinforcement between the upper flange portion 5a of the outer panel 5 and the upper flange portion 4a of the inner panel 4, and between the lower flange portion 5b of the outer panel 5 and the lower flange portion 4b of the inner panel 4. An adhesive reservoir space 9 is formed at each of the notch-like recesses 8 of the upper flange portion 6a and the lower flange portion 6b in the ment 6. Each adhesive reservoir space 9 is located on the inner side (base end side) in the standing direction from the normal end surfaces 5aa, 4aa (5bb, 4bb) of the flange portions 5a, 4a (5b, 4b) of the outer panel 5 and the inner panel 4. It is formed in a state of being retracted toward.

  The upper and lower flange portions 4a, 5a, 6a (4b, 5b, 6b) in the inner panel 4, the outer panel 5 and the reinforcement 6 are bonded to an adhesive 10 and spot welds (dots) as shown in FIGS. And a plurality of spot welds (spot welds) 11 formed by welding. The adhesive 10 bonds the upper and lower flange portions 6a and 6b of the reinforcement 6 to at least one of the upper and lower flange portions 4a and 4b of the inner panel 4 or the flange portions 5a and 5b of the outer panel 5. In the embodiment, the adhesive 10 bonds the flange portion 6 a (6 b) of the reinforcement 6 only to the flange portion 4 a (4 b) of the inner panel 4. Each spot welding portion 11 fixes three members of the inner panel 4, the reinforcement 6 and the flange portions 4a, 6a, 5a (4b, 6b, 5b) of the outer panel 5 in the vicinity of each adhesive reservoir space 9. In this embodiment, the fixing position is set to the base end side of the flange portions 4a, 6a, 5a (4b, 6b, 5b) rather than the adhesive reservoir spaces 9.

  Therefore, in such a side sill structure, the inner panel 4, the reinforcement 6 and the flange portions 4a, 6a, 5a (4b, 6b, 5b) of the outer panel 5 are bonded using the adhesive 10 and spot welding. At the time of integration, the adhesive 10 tries to protrude from the mating surface of the flange portion 4a (4b) of the inner panel 4 and the flange portion 6a (6b) of the reinforcement 6, but the adhesive 10 is shown in FIGS. 4, the adhesive 10 accumulates in the adhesive reservoir space 9, and the adhesive 10 protrudes outward from the end faces 4aa and 6aa (4bb and 6bb) of both flange portions 4a and 6a (4b and 6bb). Is prevented. In this case, as shown in FIG. 2, part of the adhesive 10 may sometimes protrude from the mating surface of the inner panel 4 and the reinforcement 6 into the closed section 7 (downward in FIG. 2). However, since this is not exposed to the outside, there is no problem, and based on this, the flange 4a (4b) of the inner panel 4 and the flange 6a (6b) of the reinforcement 6 are not affected. This further suppresses the adhesive 10 from protruding from the both end faces 4a, 6a (4b, 6b). FIG. 4 shows a state where the outer panel 5 is removed.

  On the other hand, as shown in FIG. 5, in the case of a conventional structure in which the adhesive reservoir space 9 is not formed between the inner panel 4 and the outer panel 5, the adhesive 10 is formed between the inner panel 4 and the reinforcement. The flange 6 protrudes outward from the end faces 4aa, 6aa (4bb, 6bb) of both flange portions 4a, 6a (4b, 6b) of the ment 6. For this reason, in the case of such a conventional structure, trouble will arise in this post process (for example, painting process etc.). FIG. 5 also shows a state in which the outer panel 5 has been removed.

  Further, in the above-described vehicle body joining structure, the processing necessary for forming the adhesive reservoir space 9 is only the processing for forming the notch-shaped recess 8 with respect to the flange portion 6a (6b) of the reinforcement 6. Moreover, the processing is processing from the end surface 6aa (6bb) side with respect to the flange portion 6a (6b) of the reinforcement 6. For this reason, the process is extremely easy, unlike the process for the joint surface of the flange portion 6a (6b).

  In the present embodiment, the thickness of the outer panel 5 is made thinner than the thickness of the inner panel 4 and the thickness of the reinforcement 6. In the side sill 1 as the strength member, the inner panel 4 and the reinforcement 6 By configuring the closed section 7A, the strength is ensured, and the outer panel 5 does not contribute much to securing the strength. For this reason, the upper and lower flange portions 5a and 5b of the outer panel 5 are fixed to the inner panel 4 and the upper and lower flange portions 4a and 6a (4b and 6b) of the reinforcement 6 only by spot welding. The upper and lower flange portions 6 a and 6 b of the reinforcement 6 are not bonded to the upper and lower flange portions 5 a and 5 b of the outer panel 5. Thereby, when comprising the side sill 1 with the outer panel 5, the inner panel 4, and the reinforcement 6, the usage-amount of the adhesive agent 10 can be reduced.

  Next, a method for assembling the vehicle body joint structure will be described.

  First, the inner panel 4, the outer panel 5, and the reinforcement 6 are prepared for manufacturing the vehicle body joint structure. Of course, the inner panel 4, the outer panel 5, and the reinforcement 6 have an upper flange portion 4a (5a, 6a) and a lower flange portion 4b (5b, 6b), respectively. A plurality of cutout recesses 8 are formed in the flange portions 6a and 6b on the side.

  Next, the adhesive 10 is applied to at least one of the upper and lower flange portions 4a and 4b of the inner panel 4 and the upper and lower flange portions 6a and 6b of the reinforcement 6, and the upper and lower flange portions 4a and 6a of the both 4 and 6 are applied. Bonding is performed with (4b, 6b) superposed. This is because the inner panel 4 and the reinforcement 6 constituting the substantial strength member (closed section structure) are first integrated by the adhesive 10.

  Next, the upper and lower flange portions 6a and 6b of the reinforcement 6 are overlapped with the upper and lower flange portions 5a and 5b of the outer panel 5, and the structure of the inner panel 4 and the reinforcement 6 (closed section 7A structure). The outer panel 5 is positioned with respect to. This is because spot welding is subsequently performed in a state where the inner panel 4, the reinforcement 6 and the outer panel 5 are positioned.

  Next, spot welding is performed on the inner panel 4, the reinforcement 6 and the outer panel 5. This is because the inner panel 4, the reinforcement 6 and the outer panel 5 are integrated. In this case, spot welding is performed on each of the positions near the notch-shaped recesses 8 and closer to the base end side of the flange portions 4a, 5a, 6a (4b, 5b, 6b). As a result, the inner panel 4 and the reinforcement 6 are fixed by spot welding in addition to the adhesion by the adhesive 10, and the substantially strong member in the side sill 1 is formed by the closed cross-sectional structure 7 </ b> A that constitutes the inner panel 4 and the reinforcement 6. The function as will be demonstrated accurately. On the other hand, the adhesive 10 is not used for attaching the outer panel 5 that does not contribute to securing the strength, and the amount of the adhesive 10 used can be reduced.

  FIG. 8 shows a second embodiment. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the second embodiment, the end surface 6aa (6bb) of the flange portion 6a (6b) of the reinforcement 6 is formed in a wave shape as shown in FIG. 6 (only one end surface 6aa is shown). As a result, the flange portion 6a of the reinforcement 6 is assembled so as to be sandwiched between the flange portion 4a of the inner panel 4 and the flange portion 5a of the outer panel 5, whereby the wavy end surface 6aa of the flange portion 6a of the reinforcement 6 is obtained. A large amount of the adhesive reservoir space 9 is formed based on the recess 8 of (6bb), and the protrusion of the adhesive 10 at the time of assembly can be suppressed more accurately.
