Description

[Technical Field]

[0001] The present invention relates to a clip engagement structure and a separator attachment structure. [Background technology]

[0002] A conventional technique is known in which a foaming agent is filled into a closed-section vehicle body frame member for the purpose of improving sound insulation inside the vehicle cabin and preventing the intrusion of foreign matter such as rainwater and dust into the vehicle cabin from the outside. A separator is fixed inside the vehicle body frame member, with a foamable base material before foaming held by a holder plate (also called a "carrier"). This foamable base material foams and expands by utilizing external heat during a drying process (baking process) after electrodeposition coating of the vehicle body.

[0003] For example, Patent Document 1 (JP 2000-271934 A) discloses a separator (partitioning tool) in which a plate-shaped foamable base material having an outer shape similar to the closed cross-sectional shape of a vehicle body frame member is held by a holder plate. This separator is attached during the vehicle body assembly process before the inner panel and outer panel that constitute the vehicle body frame member are joined together.

[0004] An engaging clip is formed at one location on the outer edge of the holder plate. This engaging clip is engaged with an engaging hole on the inner panel side to position and fix the separator within the inner panel. The separator is placed inside the vehicle body frame member formed by joining the inner panel and outer panel so as to block the hollow portion of the closed cross section. When external heat is applied to the separator during the drying process after electrodeposition coating, the foamable base material foams, closing the gap around the holder plate.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-271934 Summary of the Invention [Problem to be solved by the invention]

[0006] As described above, the separator is attached to the inner panel before the inner panel and outer panel are joined during the vehicle body assembly process. This separator is often attached to the inner panel by a worker. Even if the worker assembles the separator incorrectly, it cannot be detected after the inner panel and outer panel are joined.

[0007] There are various types of vehicle body frame members that can accommodate separators, such as roof side rails, center pillars, and side sills. Furthermore, in some cases, multiple separators are installed at predetermined intervals within these vehicle body frame members. Furthermore, the closed cross-sectional shapes of the vehicle body frame members into which the separators are installed vary from one to another. Therefore, dozens of different shapes of separators are used in a single vehicle body. Skill is required for an operator to understand the shapes of all the separators and install them correctly.

[0008] Therefore, some systems address this issue by providing multiple engagement clips on the holder plate and varying the number, spacing, and orientation of the engagement clips for each type.By varying the number, spacing, and orientation of the engagement clips for each type, if an engagement clip cannot be attached to the engagement hole, the worker can immediately recognize that the assembly is incorrect.

[0009] However, when the separator is installed inside the vehicle body frame member, the engaging clip protrudes outside the inner panel. Electrical wiring and various structures are arranged on the outer surface of the inner panel. It is necessary to consider the layout of the engaging clip so as not to interfere with these electrical wiring and structures. As a result, the layout of the engaging clip is limited, and only minor changes are required for each type of clip, making it difficult for workers to visually identify them.

[0010] The present invention aims to provide a clip engagement structure and a separator mounting structure that not only allows an operator to easily visually identify corresponding parts during assembly, but also prevents incorrect assembly. [Means for solving the problem]

[0011] The first aspect of the present invention is a clip engagement structure comprising a clip hole drilled in a panel and an engaging clip attached to the clip hole, the engaging clip comprising a base abutting against one side of the panel, a main body formed integrally with the base and protruding from the clip hole to the other side of the panel, and locking claws formed at both ends of the main body that pass through the clip hole and are hooked onto the other side of the panel, the base-side ends of the locking claws being elastically deformable toward the end of the main body, the main body having two side surfaces perpendicular to a line connecting the two locking claws formed in different shapes, the side surfaces being formed symmetrically on the end sides of the main body with the center in the direction of the two end portions sandwiched therebetween, the clip hole having portions through which the side surfaces pass being formed in similar shapes, and the portion through which the locking claws pass being formed to a size that allows the locking claws to pass by elastically deforming the locking claws.

[0012] The second aspect of the present invention is a separator mounting structure comprising a skeletal member in which the panel of the first invention and another panel are joined to form a hollow closed cross section, and a separator having the engaging clip of the first invention and housed within the closed cross section, wherein the separator has a plate body that separates the closed cross section and a foamable base material held by the plate body, the plate body being formed on the opposite side of the main body portion of the base attached to the engaging clip, and the foamable base material foams upon receiving heat from outside to close the closed cross section. [Effects of the Invention]

[0013] According to the present invention, an engaging clip to be attached to a clip hole in a panel comprises a base that abuts against one surface of the panel, a main body that protrudes from the clip hole onto the other surface of the panel, and a locking claw that hooks onto the other surface of the panel. The main body has two side surfaces that are different in shape on the side perpendicular to the line connecting the two locking claws, and these side surfaces are formed symmetrically on both ends of the main body with respect to the center of the center of the two ends. The clip hole has similar shapes at the portions through which the side surfaces pass, so that an operator can easily visually identify the engaging clip that corresponds to the clip hole. Furthermore, since the assembly direction is only one way, incorrect assembly can be prevented. [Brief explanation of the drawings]

[0015] An embodiment of the present invention will be described below with reference to the drawings. The vehicle body 1 shown in FIG. 1 is a body-in-white. A body-in-white is a vehicle body in which only the body assembly has been completed and before electrodeposition painting. This vehicle body 1 has a monocoque structure in which panel members and body frame members are joined together. The body frame members are formed almost symmetrically on both the left and right sides of the vehicle body 1. Each body frame member has a hollow closed cross section formed by joining an inner panel and an outer panel.

[0016] The body frame members arranged on both sides of the vehicle body 1 include left and right front pillars (A pillars) 2, 2', center pillars (B pillars) 3, 3', quarter pillars (C pillars) 4, 4', and rear pillars (D pillars) 5, 5' that extend in the vertical direction of the vehicle body 1. Further body frame members include roof side rails 6, 6' and side sills 7, 7' arranged on the left and right sides of the vehicle body 1.

[0017] The roof side rails 6, 6' connect the upper ends of the pillars 2 to 5, 2' to 5' and extend in the longitudinal direction of the vehicle body 1. The side sills 7, 7' are the lower edges of door openings formed in the vehicle body 1, and are joined to both ends of the floor panel 8 in the vehicle width direction, extending in the longitudinal direction of the vehicle body 1. In the following, the pillars 2 to 5, 2' to 5', the roof side rails 6, 6' and the side sills 7, 7' may be collectively referred to as vehicle body frame members.

[0018] Separators are installed inside each of the body frame members 2 to 7, 2' to 7'. These separators are attached to inner panels before the body frame members 2 to 7, 2' to 7' are formed in the assembly process.

[0019] FIG. 2 shows the configuration of the separator 11. This separator 11 is shown as a representative example mounted on roof side rails 6, 6', which are an example of a body frame member. The separator 11 is mounted in the same position on the roof side rails 6, 6', which are formed symmetrically on the left and right. Therefore, the closed cross-sectional shape of the roof side rails 6, 6' at the position where the separator 11 is mounted is symmetrical. The same separator 11 is mounted on the left and right roof side rails 6, 6'.

[0020] Separator 11 has a holder plate 12 and a foamable substrate 13. Foamable substrate 13 is formed into a flat plate of a desired thickness by injection molding or the like. This foamable substrate 13 is made from a foamable material mixed with a foaming agent. This foamable substrate 13 foams and expands when exposed to external heat, becoming a closed-cell foam.

[0021] The holder plate 12 is made of a heat-resistant synthetic resin (thermoplastic synthetic resin) and is formed by, for example, injection molding. The holder plate 12 has a plate body 14 and an engaging clip 15. Furthermore, the engaging clip 15 has a base 16 and a clip portion 17.

[0022] The plate body 14 and the foamed base material 13 have the same outer shape. The outer shapes of the plate body 14 and the foamed base material 13 are formed to be similar to the inner periphery of the roof side rail 6, 6' to which they are attached. The foamed base material 13 is fixed in a state of face-to-face contact with the plate body 14. A plurality of retaining tacks 14a (see FIG. 3A) protrude from the surface of the plate body 14 to which the foamed base material 13 is attached. Meanwhile, retaining holes (not shown) are drilled in the foamed base material 13 at positions corresponding to the retaining tacks 14a. The retaining holes are press-fitted into the retaining tacks 14a to hold and fix the foamed base material 13.

[0023] The back surface of the base 16 is integrally formed with the thickness surface of the plate body 14 via a neck portion 14b. The base 16 has a rectangular shape in a plan view and is disposed parallel to the thickness surface of the plate body 14. Therefore, the plate body 14 and the base 16 form a substantial T-shape when viewed from below in FIG.

[0024] The long sides of the base 16 are arranged in a direction perpendicular to the thickness direction of the plate body 14. The short sides of the base 16 are arranged in the thickness direction of the plate body 14. Furthermore, the back surface of the base 16 at the center in the short side direction is supported by the neck portion 14b.

[0025] A leg portion 16a is formed at the end of the long side of the front surface of the base 16. This leg portion 16a abuts against the inner surface of a rail side inner panel 6a (described later) of the roof side rail 6 (6'). A clip portion 17 is formed on the surface of the base 16. The clip portion 17 has a main body portion 18 and a locking claw portion 19 as a locking claw portion. The main body portion 18 is provided in a protruding position at the center of the base 16.

[0026] 2, 3, and 4A, the main body 18 has a symmetrical shape in the long side direction of the base 16 and an asymmetrical shape in the short side direction. Specifically, the main body 18 has a flat surface 18a formed on one side surface in the short side direction of the base 16. The main body 18 also has an isosceles portion 18b formed on the other side surface in the short side direction of the base 16. The isosceles portion 18b is inclined from a vertex 18c in the long side direction of the base 16 so as to approach the flat surface 18a. Furthermore, the vertex 18c is formed on a rounded surface having a predetermined curvature.

[0027] The flat portion 18a and the isosceles portion 18b are formed in a shape symmetrical with respect to the long side direction of the base 16, with the center of the main body 18 in between. Furthermore, the main body 18 has a flat surface 18d formed in a position symmetrical with respect to the center in the long side direction of the base 16. The flat surface 18d has a shape obtained by cutting both ends of the main body 18 in parallel.

[0028] A pair of locking claws 19 are formed on both flat surfaces 18d of the main body 18. The locking claws 19 extend from the upper surface of the main body 18 toward the base 16. The lower ends of the locking claws 19 are inclined in a direction that widens from the top. The lower ends of the locking claws 19 are elastically deformable in a direction approaching the flat surfaces 18d.

[0029] Here, a brief description will be given of the configuration of the roof side rail 6 on the left side of the vehicle body 1 with reference to Fig. 3A. The roof side rail 6 shown in Fig. 3A is a cross section of part A in Fig. 1 in the vehicle width direction, viewed from the rear of the vehicle body 1 to the front.

[0030] The roof side rail 6 has a rail side inner panel (hereinafter referred to as "inner panel") 6a and a reinforcement rail side outer panel (hereinafter referred to as "outer panel") 6b joined together to form a hollow closed cross section 6e.

[0031] The inner panel 6a is disposed on the inside in the vehicle width direction (toward the passenger compartment). The outer panel 6b is disposed on the outside in the vehicle width direction (toward the exterior of the vehicle). Furthermore, the exterior side of the outer panel 6b is covered with a side outer panel 6c. The upper side of the outer panel 6b and the side side of the roof top panel 9 in the vehicle width direction are surface-joined by a so-called mohawk groove 10.

[0032] As shown in FIG. 3A, the separator 11 is housed within a closed cross section 6e formed by the inner panel 6a and the outer panel 6b.

[0033] The inner panel 6a is provided with a clip hole 6d through which the clip portion 17 of the separator 11 passes. As shown in Fig. 4A, the clip hole 6d is formed in a shape similar to that of the flat portion 18a and the isosceles portion 18b of the main body 18, with a small gap therebetween.

[0034] The flat portion 18a is formed on the front side of the vehicle body 1 relative to the inner panel 6a. The isosceles portion 18b is formed on the rear side of the vehicle body 1 relative to the inner panel 6a. Furthermore, the clip hole 6d is formed in a shape such that the portion corresponding to the locking claw portion 19 of the main body 18 can be passed through by elastically deforming the locking claw portion 19. The outer periphery of the locking claw portion 19 is formed in an arc shape.

[0035] The clip hole 6d corresponding to this locking claw portion 19 is formed in a shape that allows the lower end of the locking claw portion 19 to be hooked onto the outside of the clip hole 6d in a normal state where no external force is applied to the locking claw portion 19. In other words, the outer edge of the clip hole 6d corresponding to the lower end of the locking claw portion 19 is formed in a similar shape that is smaller than the outer periphery of the locking claw portion 19. Therefore, as shown in Fig. 4A, the clip hole 6d is formed in an isosceles triangle with arc-shaped corners so that the clip portion 17 can pass through it.

[0036] 3A shows a state in which the clip portion 17 of the separator 11 is fixed by passing through (passing through) the clip hole 6d of the inner panel 6a from the inside. In this state, the leg portion 16a formed on the base 16 abuts against the inner surface of the inner panel 6a. Also, the locking claw portion 19 of the clip portion 17 is on the outer surface of the inner panel 6a and is hooked onto the outer edge of the clip hole 6d. A gap equivalent to the thickness of the inner panel 6a is formed between the upper surface of the leg portion 16a and the lower end surface of the locking claw portion 19.

[0037] 4B shows a clip hole 6d' drilled in the inner panel 6a' of the right roof side rail 6' of the vehicle body 1. The closed cross section formed by the inner panels 6a, 6a' and the outer panels 6b, 6b' at the position where the separator 11 is attached has a symmetrical shape. The clip hole 6d' drilled in the right inner panel 6a' is formed in the opposite front-to-rear direction to the clip hole 6d drilled in the left inner panel 6a. In other words, the clip hole 6d is drilled in a shape that is inverted 180° with respect to the extending direction of the framework formed by the inner panels 6a, 6a' and the outer panels 6b, 6b'.

[0038] When the clip portion 17 of the separator 11 is attached in accordance with the orientation of this clip hole 6d', the separator 11 is fixed in a symmetrical state with the separator 11 attached to the left roof side rail 6. In this case, if the cross-sectional view shown in Fig. 3A is applied to the right roof side rail 6', it corresponds to the state when part A' in Fig. 1 is viewed from the front to the rear of the vehicle body 1 in a vehicle width direction cross section.

[0039] Therefore, the separator 11 can be shared by both the left and right roof side rails 6, 6'. Furthermore, the clip portion 17 of the separator 11 is formed in a shape that is asymmetrical in the thickness direction of the plate body 14. This prevents mistakes in the installation direction. If the separator 11 is turned 180°, the front-to-back directions of the installation surfaces of the foamable base material 13 are reversed on the left and right roof side rails 6, 6'. However, the foamable base material 13 closes the periphery of the plate body 14 by foaming and expanding within a closed cross section. Therefore, the foaming position of the foamable base material 13 does not shift significantly.

[0040] The plate body 14 and the foamable base material 13 of this separator 11 are formed to match the shape of the closed cross section at the position where the body frame members 3 to 7 are attached. On the other hand, the clip portion 17 of the engaging clip 15 is formed in a different shape for each position where the body frame members 3 to 7 are attached. In this case, the main body 18 of the clip portion 17 has a symmetrical shape in the long side direction of the base 16 and an asymmetrical shape in the short side direction.

[0041] Furthermore, in this embodiment, the main body 18 has a flat portion 18a formed on one side surface in the short side direction of the base 16, and an isosceles portion 18b formed on the other side surface in the short side direction of the base 16. In addition, the vertex 18c is formed as a rounded surface having a predetermined curvature.

[0042] On the other hand, the shape of the clip holes 6d, 6d' drilled in the inner panels of the respective body frame members 3 to 7, 3' to 7' is similar to the outer diameter of the clip portion 17, which is also common to all the members.

[0043] For example, Figures 5A and 5B show examples of a separator 11 attached to the same position on the left and right center pillars 3 and 3', and clip holes 6d and 6d' drilled in the inner panels 3a and 3a'. Note that the same reference numerals are used to designate parts common to Figures 4A and 4B, and the explanation will be simplified.

[0044] The plate body 14 and foam base material 13 of this separator 11 are formed in a shape similar to the hollow closed cross section formed by the inner panel 3a and outer panel (not shown) of the center pillar 3. In addition, the clip portion 17 of the engaging clip 15 is formed in a shape different from the clip portion 17 attached to the roof side rails 6, 6'. Therefore, the clip holes 6d, 6d' formed in the inner panels 3a, 3a' are also formed in a shape different from the clip holes 6d, 6d' formed in the inner panel 6a of the roof side rail 6.

[0045] Incidentally, the clip holes 6d, 6d' drilled in the inner panels 3a, 3a' of the center pillars 3, 3' are oriented upside down, that is, inverted by 180 degrees.

[0046] Specifically, the distance between the flat surface 18a and the isosceles portion 18b of the main body 18 is set to be longer than the distance between the flat surface 18a and the isosceles portion 18b of the main body 18 shown in FIG. 4A. Furthermore, the isosceles portion 18b is formed into a shape that has a curvature over its entirety. This ensures that the separator 11 can be attached in only one direction. This prevents incorrect assembly of the separator 11 attached to the center pillars 3, 3' and the separator 11 attached to the roof side rails 6, 6'.

[0047] The shapes of the main body 18 of the separator 11 and the clip hole 6d (6d') of the inner frame are set to different shapes for different mounting locations. This prevents physical misassembly. Therefore, even if an operator accidentally drops a separator 11, for example, it is easy to identify which clip hole 6d, 6d' the separator 11 is to be attached to.

[0048] Next, the operation of the separator 11 having such a configuration will be described using an example in which it is attached to the roof side rail 6.

[0049] The separator 11 is attached in an assembly process before joining the outer panel 6b to the inner panel 6a of the roof side rail 6. That is, the clip portions 17 of the separator 11, which is previously integrated, are attached from the inside to clip holes 6d drilled in the inner panel 6a. In this embodiment, the separator 11 is attached to the inner panel 6a by the clip portions 17. Therefore, when attaching the holder plate 12 of the separator 11 to the inner panel 6a, it is not heated, and accidental foaming of the foamable base material 13 can be prevented.

[0050] The main body 18 is asymmetrical in the front-to-rear direction of the vehicle body 1, but is symmetrical in the vertical direction perpendicular to the front-to-rear direction. Furthermore, the main body 18 of the clip portion 17 and the clip hole 6d are formed to have similar shapes. Therefore, if the separator 11 is attached to the left and right roof side rails 6, 6' in the wrong direction, it will not be physically possible to attach it, thereby preventing incorrect assembly.

[0051] The shape of the main body 18 is different for each mounting location, which prevents incorrect assembly at each mounting location. Furthermore, a common separator 11 is used for the symmetrical mounting locations, which allows for cost reductions through the use of common parts.

[0052] Then, the inner panel 6a and the outer panel 6b are joined together in a predetermined manner to form a hollow, closed cross section inside. Similarly, in the other body frame members 3 to 7, the separator 11 is attached to the inner panel in a predetermined manner, and then the inner panel and the outer panel are joined together to form a hollow, closed cross section.

[0053] Then, the assembled vehicle body 1 (see FIG. 1) is electrocoated, and the foamable base material 13 of each separator 11 is foamed and expanded by utilizing the heat received from the outside during the subsequent drying process (baking process), thereby closing the gaps around the holder plate 12 within the closed cross section.

[0054] Because the separator 11 is installed inside a closed cross section formed by welding the inner panel and the outer panel, it is not possible to check whether the separator 11 is properly attached after the assembly of the vehicle body 1 is complete. However, in this embodiment, the shape of the clip portion 17 of the separator 11 is different for each attachment portion of the corresponding vehicle body frame members 2 to 7. This prevents incorrect assembly. Therefore, the foaming of the foamable base material 13 can reliably close gaps around the plate main body 14 within the closed cross section of each vehicle body frame member 2 to 7.

[0055] Therefore, for example, if a hole that becomes unnecessary after the assembly process is drilled in the panel at the portion where the foamable base material 13 is foamed, this hole will be blocked by the foaming of the foamable base material 13, thereby maintaining airtightness.

[0056] Furthermore, the separator 11 is attached to the attachment portion of the other body frame member 2' to 7' by being turned 180 degrees, which allows for cost reduction by sharing parts.

[0057] Furthermore, in this embodiment, one separator 11 is formed with one clip portion 17. The shape of the main body portion 18 formed on this clip portion 17 is different for each attachment portion. Meanwhile, the clip holes 6d, 6d' on the non-attachment side are shaped to correspond to the clip portion 17, thereby preventing incorrect assembly.

[0058] In addition, since it is only necessary to make one clip portion 17 have different shapes depending on the attachment location, the degree of freedom in design is increased and the optimum shape can be selected. Furthermore, since only one clip hole 6d, 6d' is required to be formed on the non-attachment side, molding is simplified and production costs can be reduced.

[0059] Furthermore, the main body 18 of the clip portion 17 is positioned relative to the clip holes 6d, 6d' by the flat portion 18a and the isosceles portion 18b. Therefore, fewer mating surfaces are required to position the main body 18 and the clip holes 6d, 6d'. Furthermore, there is only one clip portion 17 per separator 11. These features make it easier to manufacture the molds (injection molding molds, press molds) that form the main body 18 and the clip holes 6d, 6d', and reduce the cost of mold investment.

[0060] The present invention is not limited to the above-described embodiment. For example, the separator 11 can be applied to any body frame member of the vehicle body 1 as long as the shape of the main body portion 18 satisfies the following conditions and the inner panel side has clip holes 6d, 6d' corresponding to the main body portion 18 and the clip portion 17. 1) The main body 18 has a flat surface 18a formed on one side thereof and an isosceles surface 18b formed on the other side thereof. 2) The flat portion 18a and the isosceles portion 18b are formed symmetrically with respect to a line connecting their centers.
