Description

Technical Field

[0001] This invention relates to the side structure of a vehicle body. Background Technology

[0002] Conventionally, a vehicle body side structure is known in which the hollow portion of a center pillar extending upward from the upper surface of the lower longitudinal beam is separated by a partition member near the base of the center pillar, and a filling chamber of foamed filler material is formed between the upper surface of the lower longitudinal beam and the partition member (see, for example, Patent Document 1). Specifically, this vehicle body side structure has an injection port for foamed filler material communicating with the filling chamber on the inner side of the center pillar in the vehicle width direction. Furthermore, the partition member has a wall portion that changes the injection direction of the foamed filler material injected from the injection port. This wall portion is arranged opposite to the injection port and is formed such that it gradually shifts inward as it extends upward.

[0003] Based on this side structure of the vehicle body, the wall section causes the flow of the foamed filler material injected from the injection port to be oriented downwards, thereby promoting the foaming of the filler material on the upper surface of the lower longitudinal beam.

[0006] Patent Document 1: Japanese Patent No. 6856680 Summary of the Invention

[0007] However, in conventional vehicle body side structures (for example, see Patent Document 1), because the foaming of the filling material begins at the upper surface of the lower longitudinal beam directly below the wall, it is sometimes impossible to fill the foamed filling material to all the corners and edges of the filling chamber.

[0008] The objective of this invention is to provide a vehicle body side structure that can reliably fill the filling material throughout the filling chamber compared to the past.

[0009] The vehicle side structure of the present invention, which solves the above-mentioned problems, is characterized by having: a pillar extending in the vertical direction of the vehicle side and forming a hollow cross section; an injection port formed on the inner side of the pillar in the vehicle width direction for injecting filling material into the hollow cross section; an upper component and a lower component disposed on the hollow cross section such that they are spaced apart from each other in the vertical direction from the injection port; a filling chamber for the filling material formed between the upper component and the lower component; and a wall portion formed in the filling chamber opposite to the injection port, the wall portion being inclined such that it gradually shifts outward in the vehicle width direction as it approaches one of the two ends of the filling chamber in the vehicle front-rear direction.

[0040] Next, with appropriate reference to the accompanying drawings, a method (implementation) for carrying out the vehicle body side structure of the present invention will be described in detail.

[0041] The following description uses an example of a structure in which a foamed resin (filler material) is formed within the hollow cross-section of the center pillar. Incidentally, the purpose of this foamed resin filling structure at the center pillar is to improve NV (Noise, Vibration, and Air) performance during vehicle operation. Therefore, the vehicle body side structure of this invention is not limited to the center pillar; it can be applied to other pillars as long as their purpose is to improve NV performance.

[0042] In this embodiment, the vehicle body side structures are arranged on the left and right sides of the vehicle body, corresponding to the left and right center pillars, respectively. These vehicle body side structures have a symmetrical structure. Therefore, in this embodiment, only the left side vehicle body structure will be described, and a detailed description of the right side vehicle body structure will be omitted.

[0043] Figure 1 This is a partially enlarged side view of the side structure S on the left side of the vehicle body.

[0044] like Figure 1 As shown, the side structure S of the vehicle body is configured such that the hollow cross section of the central pillar 2 has an upper component 4 and a lower component 3.

[0045] also, Figure 1 In the middle, the upper component 4 and the lower component 3 are represented by dashed lines (dotted lines).

[0046] The center pillar 2 extends upward from the lower longitudinal beam 1 that extends along the front-rear direction on both sides of the vehicle body and connects to the roof side beam (not shown).

[0047] In this embodiment, the central column 2 is... Figure 1 When viewed from the left side as shown, it extends in a manner that forms a large width on the side of the lower longitudinal beam 1 and gradually narrows in width towards the top.

[0048] Furthermore, the leading edge of the center pillar 2 slopes upwards and then gradually moves backwards. In contrast, the trailing edge of the center pillar 2 extends substantially perpendicularly to the lower longitudinal beam 1. Incidentally, in this embodiment, the trailing edge of the center pillar 2 forms part of the front side of the door opening 5, which is opened and closed by the rear sliding door (not shown). Furthermore, a door frame 6 for the rear sliding door (described later) is formed at the base of the center pillar 2 on its inner side. Figure 6 ).

[0049] Figure 2 yes Figure 1 Sectional view II-II.

[0050] like Figure 2 As shown, the center pillar 2 is positioned on the outer side in the vehicle width direction. Figure 2 The outer component 7 of the center pillar on the left side and the component positioned on the inner side in the vehicle width direction ( Figure 2 The inner component 8 of the central pillar (on the right side) is joined in the vehicle width direction, forming a hollow section 9 on the inside.

[0051] In this embodiment, the outer component 7 of the central column is formed by a front portion 7a and an outer portion 7b, wherein the front portion 2a is... Figure 2 When viewed in cross-section, the central pillar 2 extends outwards towards the rear in the vehicle width direction, while also exhibiting multi-layered wave-like shaping. This outer portion 7b extends from the rear edge of the front portion 7a in the front-rear direction.

[0052] In addition, the inner pillar member 8 is formed by an inner portion 8a extending in the front-rear direction and a rear portion 8b that bends at approximately a right angle from the rear edge of the inner portion 8a and extends outward in the vehicle width direction.

[0053] Furthermore, regarding the shape of the hollow cross-section 9 of the central column 2 in this embodiment, besides being similar to that of the door frame 6 described later (see...), Figure 6 Apart from the bulge 8c that protrudes outward in the width direction of the vehicle, it is roughly a right-angled trapezoid with the front side of the center pillar 2 as the hypotenuse. However, the shape of the hollow section 9 is not limited to this.

[0054] also, Figure 2 In the figure, reference numeral 3 indicates the lower component, reference numeral P indicates the injection port of the filling material formed in the inner component 8 of the central column, and reference numeral W indicates the component formed in the upper component 4 (see reference). Figure 1 The wall portion of the component 3, the injection port P, the upper component 4, and the wall portion W will then be described in detail.

[0055] Next, the lower component 3 (refer to) disposed within the hollow section 9 of such a central column 2 will be described. Figure 1 ) and upper component 4 (refer to Figure 1 ).

[0056] Figure 3 Is Figure 1 A partially enlarged side view showing the interior of the hollow section 9 of the central column 2, with the outer component 7 of the central column removed from section III. Furthermore, Figure 3 In the diagram, the portion of the injection port P that overlaps with the wall portion W of the upper component 4 (described later) is indicated by a dashed line (dotted line).

[0057] like Figure 3 As shown, a lower component 3 and an upper component 4 are arranged in the hollow section 9 of the central column 2.

[0058] These lower components 3 and upper components 4 are formed from bent plates.

[0059] Furthermore, the lower component 3 and the upper component 4 are spaced apart by a predetermined interval and are arranged in the hollow section 9 such that their faces are oriented in the vertical direction.

[0060] Therefore, the hollow section 9 of the central column 2 is divided vertically by the lower component 3 and the upper component 4. Thus, a filling chamber 11 filled with filling material is formed between the lower component 3 and the upper component 4.

[0061] Furthermore, the lower component 3 and the upper component 4 are arranged such that they are separated from each other by an injection port P for filler material in the vertical direction, thereby allowing the interior of the center pillar 2 to communicate with the filling chamber 11. A spray nozzle is installed at this injection port P from the interior of the center pillar 2 to spray liquid filler material, which is an uncured foaming resin, into the filling chamber 11. Incidentally, the filler material in this embodiment is envisioned as a foaming amino resin, but it is not limited to this.

[0062] In addition, in the following explanation, such as Figure 2 As shown, when comparing the distances between the two ends of the filling chamber 11 in the front-rear direction of the vehicle body and the injection port P, the end that is farther from the injection port P is defined as the first end 11a, and the end that is closer to the injection port P is defined as the second end 11b.

[0063] like Figure 3 As shown, the lower component 3 and the upper component 4 have mutually parallel planar portions 12 and 16.

[0064] The lower component 3 has an inclined portion 13 connected to the flat portion 12 on the side of the second end 11b. The inclined portion 13 is inclined in such a way that it gradually moves upward as it approaches the second end 11b.

[0065] Additionally, the upper component 4 has an inclined portion 17 connected to the flat portion 16 on the side of the second end 11b. This inclined portion 17 is inclined in a manner that gradually shifts upwards as it approaches the second end 11b side.

[0066] Furthermore, the inclined portion 17 of the upper component 4 is inclined from the end edge of the planar portion 16 that is biased towards the first end 11a side compared to the injection port P, while the inclined portion 13 of the lower component 3 is inclined from the end edge of the planar portion 12 that is biased towards the second end 11b side compared to the injection port P.

[0067] Figure 4 It means in Figure 1 A magnified three-dimensional view of the hollow cross-section 9 of the central pillar 2, which is observed from the front obliquely upward outside the vehicle, after the removal of the outer component 7 of the central pillar at part III.

[0068] like Figure 4 As shown, a flange 18 is formed on the periphery of the lower component 3. The flange 18 rises from the periphery of the lower component 3 toward the filling chamber 11 in a manner that is approximately along the inner circumferential surface of the hollow section 9 of the central column 2. Furthermore, the rising corner of the flange 18 is formed by a curved portion C with an R-angle.

[0069] Furthermore, the flange 18 extends along the inner circumferential surface of the central column 2 and is formed over approximately the entire circumference of the lower component 3, except for a portion corresponding to the reinforcing rib B described later.

[0070] Additionally, the lower component 3 has a protrusion 18a that extends partially upward from the flange 18. This protrusion 18a is arranged in a plurality of portions (three in this embodiment) spaced at predetermined intervals in the circumferential direction of the lower component 3.

[0071] Furthermore, in this embodiment, the lower component 3 is envisioned to be joined to the inner circumferential surface of the central column 2 by spot welding or the like at the protrusion 18a.

[0072] In addition, the lower component 3 has a bulge 21 that bulges upward. In this embodiment, the bulge 21 is formed into a platform shape with a flat top surface.

[0073] In this embodiment, the lower component 3 has multiple bulges 21. Specifically, the bulges 21 are as follows: Figure 4 The terrain shown is such that two are arranged in the front-to-back direction in the planar part 12, and as follows: Figure 2 As shown, one is formed in the inclined section 13.

[0074] Such a bulge 21 is conceived to be formed by stamping the plate part with the upper part being convex, but it can also be formed with the lower part being convex.

[0075] In addition, such as Figure 4As shown, the lower component 3 is reinforced with a reinforcing rib B by means of a strip that protrudes upwards in a manner corresponding to the periphery of the break in the middle of the flange 18. Figure 2 As shown, the reinforcing rib B is formed on the outer side of the filling chamber 11 in the vehicle width direction, approximately at the center of the front-rear direction of the planar portion 12.

[0076] Furthermore, reinforcing rib B extends from the inside in the vehicle width direction ( Figure 2 (On the right side) the flange 18 extends in the front-back direction to partially compensate for the break in the middle.

[0077] Incidentally, the lower component 3 of this embodiment is envisioned as a synthetic resin molded article. Furthermore, the notch of the flange 18 is envisioned as being formed as a connecting part when the lower component 3 is molded in the mold.

[0078] Therefore, the position of the notch in the flange 18 and the reinforcing rib B arranged to fill it are not limited to this, and can be changed depending on the position of the joint during forming.

[0079] Next, let's explain component 4.

[0080] like Figure 4 As shown, a flange 19 is formed on the periphery of the upper component 4. The flange 19 rises from the periphery of the upper component 4 toward the filling chamber 11 in a manner that is approximately along the inner periphery of the hollow section 9 of the central column 2. Furthermore, the rising corner of the flange 19 is formed by a curved portion C with an R-angle.

[0081] Furthermore, the flange 19 extends along the inner circumferential surface of the central column 2 and is formed over approximately the entire circumference of the upper component 4.

[0082] Additionally, the upper component 4 has a protrusion 19a that extends partially downward from the flange 19. This protrusion 19a is arranged in a plurality of portions (three in this embodiment) spaced at predetermined intervals along the circumference of the upper component 4.

[0083] Furthermore, in this embodiment, the upper component 4 is envisioned to be joined to the inner circumferential surface of the central column 2 by spot welding or the like.

[0084] In addition, the upper component 4 has an upwardly bulging portion 21. And like the bulging portion 21 of the lower component 3, it is shaped like a plateau with a flat top surface.

[0085] Furthermore, the bulge 21 of the upper component 4 is formed such that two are arranged in the front-to-back direction in the planar portion 16.

[0086] Such a bulge 21 is conceived to be formed by stamping the plate part in a way that the upper part is convex, but it can also be formed in a way that the lower part is convex.

[0087] In addition, such as Figure 4 As shown, the upper component 4 has a wall portion W opposite to the injection port P. Furthermore, in this embodiment, the wall portion W is formed in the inclined portion 17 of the upper component 4.

[0088] That is, such as Figure 2 As shown, the wall portion W is formed on the side of the second end portion 11b compared to the central portion in the front-rear direction of the filling chamber 11.

[0089] In addition, the wall portion W is located inside the vehicle width direction compared to the center of the lower component 3 in the vehicle width direction.

[0090] Furthermore, the wall portion W gradually moves outward in the vehicle width direction towards the first end 11a, which is farther from the injection port P. Figure 2 The left side is tilted by displacement.

[0091] Figure 5 This is a magnified 3D view of the front part of the upper component 4.

[0092] like Figure 5 As shown, in this embodiment, the wall portion W is formed by partially bending the upper component 4 toward the lower component 3.

[0093] Specifically, the wall portion W is composed of a slice formed by a partial cut in the inclined portion 17 of the upper component 4.

[0094] Furthermore, the corner of the wall after the W bend has an R-angle, and a recess 15 with a local concavity at the corner is formed in the center of the extension direction of the bend line.

[0095] In addition, the recess 15 can also be changed into a convex part with a local protrusion at the corner.

[0096] There are no particular limitations on the upper component 4 in this embodiment, but it is preferably formed of iron plate.

[0097] Figure 6 It means looking from the inside of the car at an angle above. Figure 1 A magnified 3D view of the VI-VI section.

[0098] like Figure 6 As shown, in this embodiment, the vehicle body side structure S is formed with a door frame 6 at the base of the center pillar 2 on the inner side of the vehicle body as described above.

[0099] The door sleeve 6 constitutes the lower door sleeve component, which supports the rear sliding door (not shown) on the lower side and guides the rear sliding door when it slides in the front-rear direction of the vehicle body. Furthermore, the door sleeve 6 is positioned at the front end of the sliding range of the rear sliding door.

[0100] Specifically, the door frame 6 is formed inside the vehicle width direction compared to the center pillar 2, and is formed at a position offset from the first end 11a on the side opposite to the second end 11b on which the wall portion W is formed.

[0101] Furthermore, the door frame 6 is formed below the filling material injection port P. Also, the upper end of the door frame 6 is located above the lower component 3.

[0102] Effects and Functions

[0103] The following explains the effects of the vehicle body side structure S in this embodiment.

[0104] In the vehicle body side structure S of this embodiment, the wall W is inclined in such a way that it gradually moves outward in the vehicle width direction as it moves towards either end of the filling chamber 11 in the front-rear direction.

[0105] According to this vehicle body side structure S, unlike the conventional vehicle body side structure where the foaming of the filling material begins below the wall (for example, see Patent Document 1), the wall W guides the filling material injected from the injection port P formed on the inside of the center pillar 2 in the vehicle width direction toward the end of the filling chamber 11.

[0106] Thus, the side structure S of the vehicle body can fill the edges and corners of the filling chambers with foamed filler material.

[0107] In addition, in such a vehicle body side structure S, the wall portion W is inclined in such a way that the side farther from the injection port P, i.e., the first end portion 11a side, gradually shifts outward in the vehicle width direction.

[0108] As a result, the direction of the filler material ejected from the injection port P in the vehicle body side structure S is changed towards the corner of the filling chamber 11 that is farther from the injection port P. With such a vehicle body side structure S, the position far from the injection port P can be filled more reliably, thus suppressing the unevenness of the filler material in the filling chamber 11 and enabling the filler material to be filled in a way that is distributed throughout the filling chamber 11.

[0109] In addition, in this side structure S of the vehicle body, the wall W is located inside the vehicle width direction compared to the center of the lower part 3 in the vehicle width direction.

[0110] Thus, the side structure S of the vehicle body brings the wall W closer to the injection port P. With this side structure S, it is possible to prevent the filler material injected from the injection port P from scattering around without reaching the wall W, and it is also possible to suppress the leakage of filler material from the periphery of the lower part 3 and the upper part 4.

[0111] In addition, in this side structure S of the vehicle body, the wall W is formed by partially bending the upper part 4 toward the lower part 3.

[0112] According to this side body structure S, unlike the structure in which the wall W is mounted on the upper part 4 through other parts, the weight of the side body structure S can be reduced and the manufacturing process can be simplified.

[0113] In addition, in this body side structure S, a recess 15 (or a protrusion) is provided at the bend of the wall W, thereby improving the rigidity at the bend of the wall W.

[0114] The W-shaped part deformed towards the body of the vehicle.

[0115] In addition, in this side body structure S, the lower part 3 and the upper part 4 have mutually parallel planar portions 12 and 16.

[0116] According to this side structure S of the vehicle body, the filling material flows between the flat parts 12 and 16, which can prevent the filling material from being stuck in one place.

[0117] Furthermore, in the lower part 3 of such a body side structure S, there is an inclined portion 13 on the second end 11b side of the filling chamber 11 near the injection port P of the filling material.

[0118] Based on this side structure S of the vehicle body, it is possible to prevent filler material that has not been completely oriented by the wall W from remaining near the injection port P.

[0119] Furthermore, in the upper part 4 of such a body side structure S, the wall part W is formed in the inclined part 17 of the upper part 4.

[0120] As a result, the orientation of the filler material injected from the injection port P is changed to a downward direction by tilting the inclined part 17 of the side structure S of the vehicle body.

[0121] According to this side structure S of the vehicle body, the filling material can be guided more reliably to the side of the lower component 3, thus preventing the filling material from being transferred to the inner wall of the center pillar 2 (filling chamber 11) and leaking out to the outside of the filling chamber 11. As a result, the side structure S of the vehicle body can more reliably fill the filling material in a manner that covers the entire filling chamber 11.

[0122] Furthermore, in this body side structure S, the inclined portion 13 of the lower component 3 is inclined from a position that is biased towards the second end 11b side compared to the injection port P.

[0123] Thus, the side structure S of the vehicle body allows the filling material that has not been completely oriented by the wall W to flow through the inclined part 13 to the flat part 12.

[0124] According to this side structure S of the vehicle body, it is possible to prevent the injection port P from being blocked by the filling material before the filling material fills the entire filling chamber 11.

[0125] Furthermore, this side body structure S allows for a wider planar section 12.

[0126] In addition, in this side structure S of the vehicle body, flanges 18 and 19 are formed on the periphery of the upper part 4 and the lower part 3 respectively.

[0127] According to this side structure S of the vehicle body, the leakage of filling material into the filling chamber 11 from the periphery of the upper part 4 and the lower part 3 can be suppressed by the flanges 18 and 19.

[0128] Furthermore, in this side body structure S, the flanges 18 and 19 have protrusions 18a and 19a. This improves the bonding strength between the side body structure S and the inner wall of the center pillar 2.

[0129] In addition, in this side structure S of the vehicle body, the lower part 3 is formed with a reinforcing rib B in a manner that corresponds to the periphery of the break in the middle of the flange 18.

[0130] According to this side body structure S, leakage from the periphery of the break in the flange 18 to the outside of the filling chamber 11 is suppressed when the filling material is filled into the filling chamber 11 from the injection port P.

[0131] Furthermore, according to the vehicle body side structure S, by causing the flow of filling material that is not completely guided from the wall portion W to the first end portion 11a to follow the extension direction of the reinforcing rib B, the filling material is more reliably guided to the first end portion 11a.

[0132] In addition, in this side structure S of the vehicle body, the upper part 4 and the lower part 3 each have multiple bulges 21.

[0133] As a result, the side structure S of the vehicle body increases the rigidity of the upper component 4 and the lower component 3.

[0134] According to this side structure S of the vehicle body, it is possible to suppress the deformation of the upper part 4 and the lower part 3 caused by filling pressure when the filling chamber 11 is filled with filling material.

[0135] In addition, in this side body structure S, the door frame 6 is formed on the inside side in the vehicle width direction compared to the center pillar 2.

[0136] According to this side body structure S, when a side collision occurs, the load input to the center pillar 2 is transferred to the door frame 6 and absorbed.

[0137] In addition, the side structure S of the vehicle body prevents noise and vibration that occur in the door frame 6 when the rear sliding door (not shown) is opened and closed from being transmitted to the vehicle interior via the center pillar 2 by filling material that is filled into the filling chamber 11.

[0138] In addition, in this body side structure S, the door sleeve 6 is formed at a position offset from the first end 11a side which is far from the injection port P.

[0139] Thus, the door frame 6 of the side structure S of the vehicle body is configured to correspond to the planar portions 12 and 16 that are parallel to each other in the lower part 3 and the upper part 4.

[0140] Based on this side body structure S, the load input to the center pillar 2 during a side collision can be efficiently transferred to the door frame.

[0141] Furthermore, in such a body side structure S, it is preferable that component 4 is a component made of iron plate.

[0142] According to such a body side structure S, compared with a structure having an upper part 4 made of, for example, resin, the rigidity of the upper part 4 can be improved, and the manufacturing process of the upper part 4 can be made easier.

[0143] The above describes this embodiment, but the present invention is not limited to the above embodiment and can be implemented in various ways.

[0144] In the above embodiments, it is conceivable that a second end 11b is provided on the front side of the filling chamber 11 and a first end 11a is provided on the rear side of the filling chamber 11. Alternatively, it can be configured in the opposite way, that the first end 11a is provided on the front side and the second end 11b is provided on the rear side.

[0145] In addition, in the above embodiment, a wall portion W that is unidirectionally inclined in the forward and backward direction is envisioned. However, it is also possible to design a wall portion W that, when viewed from above, is formed in a V-shape that opens outward in the vehicle width direction when facing the surface of the wall portion W opposite the injection port P.
