Description

Technical Field

[0001] This utility model relates to a vehicle body structure, and more particularly to a vehicle body side structure. Background Technology

[0002] In recent years, efforts to provide access to sustainable transportation systems that also take into account vulnerable groups such as the elderly, disabled, and children among transportation participants have become increasingly active. To achieve this goal, research and development efforts are focused on further improving transportation safety and convenience through advancements related to vehicle body structural rigidity. However, in these developments, the structural rigidity of the vehicle body side structure is a key issue.

[0003] In existing technologies, such as the front pillar structure disclosed in Japanese Patent Publication No. 2015-202761, components used in the side structure of a vehicle body (e.g., inner panels, outer panels, reinforcing members, etc.) can improve structural rigidity by joining them together. However, when these components overlap each other in a top-down view, the overall thickness of multiple components increases, making it difficult to join and fix them together simultaneously. That is, the joint cannot provide sufficient fixation for multiple overlapping components at the same time, leading to concerns about insufficient structural rigidity in the overlapping areas of multiple components. Therefore, it is necessary to improve the side structure of the vehicle body to enhance its structural rigidity.

[0004] This invention aims to improve the structural rigidity of the vehicle body side structure in order to solve the aforementioned problem. Furthermore, it contributes to the development of sustainable transportation systems. Utility Model Content

[0005] This utility model provides a side structure for a vehicle body that can improve structural rigidity.

[0006] The side structure of the vehicle body of this utility model includes: an outer panel having an outer panel flange, a notch recessed from the edge of the outer panel flange toward the root side, a first region adjacent to the notch in the front-rear direction and corresponding to the edge in the width direction, and a second region closer to the root side than the notch in the width direction; an inner panel connecting the outer panel to form a cross-sectional space and having an inner panel flange; a reinforcing member disposed within the cross-sectional space and having a reinforcing member flange; a patch piece disposed between the reinforcing member and the inner panel and having a patch piece flange; a first joint portion joining the outer panel flange, the inner panel flange, and the reinforcing member flange in the first region; a second joint portion joining the outer panel flange and the reinforcing member flange in the second region; and a third joint portion joining the reinforcing member flange, the patch piece flange, and the inner panel flange in a third region corresponding to the notch.

[0007] In an embodiment of this utility model, the edges of the reinforcing flange, the patch flange, and the inner plate flange are aligned with each other, and the reinforcing flange, the patch flange, and the inner plate flange respectively at least partially overlap with the notch.

[0008] In an embodiment of this utility model, the width of the second region is smaller than the width of the first region.

[0009] In an embodiment of this utility model, the vehicle body side structure further includes a dustproof seal, which is disposed along the edge of the second region of the outer panel flange between the outer panel flange and the reinforcing member flange.

[0010] In an embodiment of this utility model, the vehicle body side structure further includes a glass seal, which is disposed on the outer panel flange and at least partially overlaps with the dustproof seal.

[0011] In an embodiment of this utility model, the thickness of each of the reinforcing member, the inner plate, and the patch is greater than the thickness of the outer plate.

[0012] Based on the above, in the vehicle body side structure of this utility model, a notch, a first region, and a second region are provided on the outer panel flange, and the flanges of the outer panel, inner panel, reinforcing member, and patch are joined by a first joint, a second joint, and a third joint. Specifically, the first joint joins the flanges of the outer panel, inner panel, and reinforcing member in the first region; the second joint joins the flanges of the outer panel and reinforcing member in the second region; and the third joint joins the flanges of the reinforcing member, patch, and inner panel in the third region corresponding to the notch. Thus, the first and third joints each only need to join the flanges of three components, and the second joint only needs to join the flanges of two components. Compared to a structure that joins the flanges of four components simultaneously through joints, the first, second, and third joints provide a better joining effect, allowing these components to be more securely connected as a whole. Therefore, the vehicle body side structure of this utility model can improve structural rigidity.

[0013] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below, and detailed descriptions are provided in conjunction with the accompanying drawings. Attached Figure Description

Figure 5 This is a partially enlarged schematic diagram of the vehicle body side structure of another embodiment of this utility model at positions corresponding to multiple flanges. The following will be accompanied by... Figures 1 to 5 The present invention describes the specific structure of the vehicle body side structure 100 in this embodiment, but this invention is not limited thereto and can be adjusted according to requirements.

[0048] Please refer to Figures 1 to 4In this embodiment, the vehicle body side structure 100 includes an outer panel 110, an inner panel 120, a reinforcing member 130, a patch 140, a first joint 150, a second joint 160, and a third joint 170. The outer panel 110 has an outer panel flange 112, a notch 114 recessed from the edge 112a of the outer panel flange 112 towards the root, a first region 116 adjacent to the notch 114 in the longitudinal direction X and corresponding to the edge 112a in the width direction Y, and a second region 118 further towards the root than the notch 114 in the width direction Y. The inner panel 120 connects to the outer panel 110 to form a cross-sectional space 102 and has an inner panel flange 122. The reinforcing member 130 is disposed within the cross-sectional space 102 and has a reinforcing member flange 132. The patch 140 is disposed between the reinforcing member 130 and the inner panel 120 and has a patch flange 142. A first joint 150 joins the outer panel flange 112, the inner panel flange 122, and the reinforcing flange 132 in a first region 116. A second joint 160 joins the outer panel flange 112 and the reinforcing flange 132 in a second region 118. A third joint 170 joins the reinforcing flange 132, the patch flange 142, and the inner panel flange 122 in a third region 119 corresponding to the notch 114. Exemplary structures of these components will be described in detail below.

[0049] Specifically, in this embodiment, as Figures 1 to 4 As shown, the outer panel 110 is, for example, a strip-shaped member extending in the longitudinal direction X (i.e., the length direction), and has, for example, an outer panel flange 112 extending in the longitudinal direction X and configured as a thin plate on the upper side. Furthermore, a notch 114 is formed on the outer panel flange 112, for example, recessed from the edge 112a towards the root, and is a strip-shaped notch extending in the longitudinal direction X. Here, the length (dimension in the longitudinal direction X) and width (dimension in the width direction Y) of the notch 114 can be adjusted as needed. With the notch 114, components subsequently assembled inside the outer panel 110 (e.g., a portion of the reinforcing member 130 disposed within the cross-sectional space 102) are exposed outwards to facilitate the subsequent installation of the third joint 170 (as described later). Here, the strip-shaped member extending in the longitudinal direction X is not limited to being parallel to the longitudinal direction X. When the strip-shaped member has an arcuate profile, it is acceptable as long as the extending direction of the strip-shaped member extends further towards the longitudinal direction X than the width direction Y. Figure 1 , Figure 2 The outer panel 110, inner panel 120, reinforcing member 130, and patch 140 shown all belong to this state.

[0050] Furthermore, in this embodiment, as Figures 1 to 4As shown, three regions are further distinguished on the outer flange 112 of the outer plate 110. The first region 116 is adjacent to the notch 114 in the front-rear direction X and corresponds to the edge 112a in the width direction Y. That is, the first region 116 is a region on the outer flange 112 that, measured from the edge 112a towards the root, corresponds to the notch 114 in the width direction Y (with approximately equal width) and is adjacent to the notch 114 in the front-rear direction X. Alternatively, the first region 116 can be considered as a region on the outer flange 112 that, measured from the edge 112a towards the root, does not have the notch 114. Therefore, the first region 116 corresponds to the notch 114 in the width direction Y and is offset in the front-rear direction X. In contrast, the second region 118 is closer to the root side in the width direction Y than the notch 114. That is, the second region 118 is the region on the outer flange 112 that is measured from the edge of the notch 114 toward the root side, and corresponds to the notch 114 in the front-rear direction X and is adjacent to the notch 114 in the width direction Y. Alternatively, the second region 118 can be regarded as the region on the outer flange 112 that is separated along the notch 114.

[0051] Furthermore, in this embodiment, such as Figures 1 to 4 As shown, the third region 119 corresponds to the notch 114. That is, the third region 119 is located between the first region 116 and the second region 118 in the front-rear direction X and the width direction Y, and the notch 114 can be considered to be formed in the third region 119. As an example, the width of the second region 118 is smaller than the width of the first region 116 (e.g., ...). Figure 1 (As shown). That is, the second region 118 can be regarded as the region remaining on the root side after the notch 114 is formed on the outer plate flange 112, and is therefore set to be narrower than the first region 116 and the notch 114 (third region 119). In this way, three regions are further distinguished on the outer plate flange 112 of the outer plate 110, and multiple components can be joined to the three regions by the subsequent first joint 150, second joint 160, and third joint 170 respectively. However, the present invention does not limit the specific structure of the outer plate 110, the outer plate flange 112, and the notch 114, or the way the multiple regions are divided (size, relative position, etc.), which can be adjusted according to needs.

[0052] Additionally, in this embodiment, as Figures 1 to 4As shown, the inner panel 120 is, for example, a strip-shaped member extending in the longitudinal direction X (i.e., the length direction), and has, for example, an inner panel flange 122 extending in the longitudinal direction X and configured as a thin plate on the upper side. In a top view, the inner panel flange 122 of the inner panel 120 at least partially overlaps with the outer panel flange 112 of the outer panel 110, and the inner panel flange 122 at least partially overlaps with the notch 114. That is, the inner panel flange 122 extends in the longitudinal direction X to a range that at least partially overlaps with the outer panel flange 112 and the notch 114. Preferably, the inner panel flange 122 at least partially overlaps with the outer panel flange 112 in the first region 116, and at least partially overlaps with the notch 114 in the third region 119, but does not overlap with the outer panel flange 112 in the second region 118 (e.g., ...). Figure 3 and Figure 4 (As shown). Thus, the inner plate flange 122 can be further engaged with the flanges of other components via the first joint 150 and the third joint 170, but the second joint 160 may not contact the inner plate flange 122. Furthermore, the inner plate 120 connects to the outer plate 110 from the inside, and the space between the inner plate 120 and the outer plate 110 forms a cross-sectional space 102 (as shown). Figure 3 and Figure 4 (As shown). The cross-sectional space 102 is not limited to being closed or not. However, this utility model does not limit the specific structure of the inner plate 120, the inner plate flange 122, etc., which can be adjusted according to requirements.

[0053] Therefore, in this embodiment, as Figures 1 to 4 As shown, the reinforcing member 130 is, for example, a strip-shaped member extending in the longitudinal direction X (i.e., the length direction), and has a reinforcing flange 132 extending in the longitudinal direction X and configured as a thin plate on, for example, the upper side. In a top view, the reinforcing flange 132 of the reinforcing member 130 at least partially overlaps with the outer plate flange 112 of the outer plate 110, and the reinforcing flange 132 at least partially overlaps with the notch 114. That is, the reinforcing flange 132 extends in the longitudinal direction X to a range that at least partially overlaps with the outer plate flange 112 and the notch 114. Preferably, the reinforcing flange 132 at least partially overlaps with the outer plate flange 112 in the first region 116 and the second region 118, and at least partially overlaps with the notch 114 in the third region 119 (e.g., ...). Figure 3 and Figure 4(As shown). Thus, the reinforcing flange 132 can be further joined with the flanges of other components via the first joint 150, the second joint 160, and the third joint 170. Furthermore, the reinforcing member 130 is further disposed within the cross-sectional space 102 and joins with at least one of the inner plate 120 and the outer plate 110, thereby strengthening the structural rigidity of the inner plate 120 and the outer plate 110 within the cross-sectional space 102. However, this invention does not limit the specific structure of the reinforcing member 130, the reinforcing flange 132, etc., which can be adjusted according to requirements.

[0054] Furthermore, in this embodiment, such as Figures 1 to 4 As shown, the patch 140 is, for example, a strip-shaped member extending in the longitudinal direction X (i.e., the length direction), and has a patch flange 142 extending in the longitudinal direction X and configured as a thin plate on, for example, the upper side. In a top view, the patch flange 142 at least partially overlaps with the notch 114. That is, the patch flange 142 extends in the longitudinal direction X to a range that at least partially overlaps with the notch 114. Preferably, the patch flange 142 at least partially overlaps with the notch 114 in the third region 119, but does not overlap with the outer plate flange 112 in the first region 116 and the second region 118 (e.g., ...). Figure 3 and Figure 4 (As shown). Thus, the patch flange 142 can be further engaged with the flanges of other components via the third joint 170, but the first joint 150 and the second joint 160 may not contact the patch flange 142. Furthermore, the patch 140 is further disposed between the reinforcing member 130 and the inner plate 120, thereby strengthening the structural rigidity of the reinforcing member 130 and the inner plate 120. However, this invention does not limit the specific structure of the patch 140, patch flange 142, etc., which can be adjusted according to requirements.

[0055] Therefore, in this embodiment, as Figures 1 to 4 As shown, the outer panel 110, inner panel 120, reinforcing member 130, and patch 140 are joined by a first joint 150, a second joint 160, and a third joint 170. The first joint 150, second joint 160, and third joint 170 are, for example, spot welded joints formed by the flanges of the aforementioned components. Specifically, the first joint 150 joins at least partially overlapping outer panel flange 112, inner panel flange 122, and reinforcing member flange 132 (e.g., in a first region 116). Figure 3 (As shown). Preferably, the first joint 150 does not contact the patch flange 142 in the first region 116. In contrast, the second joint 160 engages at least partially overlapping the outer plate flange 112 and the reinforcing flange 132 (as shown) in the second region 118. Figure 4(As shown). Preferably, the second joint 160 does not contact the inner plate flange 122 or the patch flange 142 in the second region 118. Furthermore, the third joint 170 engages the reinforcing flange 132, the patch flange 142, and the inner plate flange 122 (as shown) that at least partially overlap with the notch 114 in the third region 119 corresponding to the notch 114. Figure 4 (As shown). Preferably, the edges of the reinforcing flange 132, the patch flange 142, and the inner panel flange 122 are aligned with each other. Thus, by providing the notch 114, the third joint 170 can be easily provided between the outer panel flange 112 and the reinforcing flange 132, the patch flange 142, and the inner panel flange 122. In other words, when the side structure 100 of the vehicle body has a patch 140, further providing the notch 114 on the outer panel flange 112 corresponding to the area of ​​the patch flange 142 makes it easier to join the additional patch 140. However, this invention does not limit the specific structure of the first joint 150, the second joint 160, and the third joint 170, etc., which can be adjusted according to requirements.

[0056] With the above-described configuration, in the vehicle body side structure 100 of this embodiment, as follows: Figures 1 to 4 As shown, the outer panel flange 112 is provided with a notch 114, a first region 116, and a second region 118, and the flanges of the outer panel 110, inner panel 120, reinforcing member 130, and patch 140 are joined by a first joining portion 150, a second joining portion 160, and a third joining portion 170. Specifically, the first joining portion 150 joins the flanges of the outer panel 110, inner panel 120, and reinforcing member 130 in the first region 116; the second joining portion 160 joins the flanges of the outer panel 110 and reinforcing member 130 in the second region 118; and the third joining portion 170 joins the flanges of the reinforcing member 130, patch 140, and inner panel 120 in the third region 119 corresponding to the notch 114. Thus, the first joint 150 and the third joint 170 each only need to join the flanges of three components, and the second joint 160 only needs to join the flanges of two components. Compared with a structure that joins the flanges of four components simultaneously through the joints, the first joint 150, the second joint 160, and the third joint 170 have a better joining effect, allowing these components to be more firmly joined together. Accordingly, the side structure 100 of the vehicle body can improve structural rigidity.

[0057] Furthermore, in this embodiment, as Figures 1 to 4As shown, multiple first joints 150 are provided along the outer plate flange 112, multiple second joints 160 are provided along the outer plate flange 112, and multiple third joints 170 are provided along the notch 114. Although described here with reference to the outer plate flange 112 and the notch 114, in the joined state, the inner plate flange 122, the reinforcing flange 132, and the patch flange 142 also overlap at least partially in different regions. Therefore, multiple first joints 150, second joints 160, and third joints 170 are also provided along the long side direction of these flanges. Specifically, multiple first joints 150 in the first region 116 and multiple third joints 170 in the third region 119 corresponding to the notch 114 are arranged in the front-rear direction X and are generally aligned in the width direction Y. In contrast, multiple second joints 160 in the second region 118 are arranged in the front-rear direction X at a position closer to the root than the third joints 170. Thus, even if the first joint 150, the second joint 160, and the third joint 170 each only join three or two flanges of the components, they can still join the outer panel 110, the inner panel 120, the reinforcing member 130, and the patch 140 at multiple locations along the long side direction of these flanges, providing a sufficient joining effect along the long side direction of these flanges, thereby improving the structural rigidity of the vehicle side structure 100. When the vehicle side structure 100 further incorporates components such as the windshield frame 104 (described later) or door pillars (not shown), the high structural rigidity of the vehicle side structure 100 can prevent deformation of the windshield frame 104 or door pillars (not shown). However, the number, arrangement, and location of the first joint 150, the second joint 160, and the third joint 170 can be adjusted according to requirements, and this invention is not limited thereto.

[0058] Furthermore, in this embodiment, such as Figures 1 to 4 As shown, the material strength of the reinforcing member 130, the inner plate 120, and the patch 140 is higher than that of the outer plate 110. Furthermore, the plate thickness (e.g., thickness t1) of the reinforcing member 130, the inner plate 120, and the patch 140 is greater than the plate thickness (e.g., thickness t2) of the outer plate 110. That is, the three components joined by the third joint 170 are each made of a high-strength material (e.g., high-strength steel) and are plate-shaped components with high plate thickness. Thus, the three components joined by the third joint 170 (i.e., the rear reinforcing member 130, the inner plate 120, and the patch 140) have high structural rigidity. Furthermore, by providing the notch 114, the flanges of only the three structurally strong components can be continuously joined by the third joint 170 (e.g., ...). Figure 4(Spot welding shown), thereby further improving structural rigidity. When the side structure 100 of the vehicle body further incorporates components such as the windshield frame 104 (described later) or door pillars (not shown), the side structure 100 of the vehicle body can prevent deformation of the windshield frame 104 or door pillars (not shown) through high structural rigidity. Here, the example uses a thickness t1 for each of the reinforcing member 130, inner panel 120, and patch 140, but different plate thicknesses are also possible. Furthermore, in other embodiments not shown, the outer panel 110 may also be a component with the same material strength and plate thickness. This invention is not limited to this and can be adjusted according to requirements.

[0059] Additionally, in other embodiments, such as Figure 1 and Figure 5 As shown, compared to the aforementioned vehicle side structure 100, the vehicle side structure 100A further includes a dust seal 180. The dust seal 180 is disposed along the edge of the second region 118 of the outer panel flange 112 between the outer panel flange 112 and the reinforcing flange 132. Specifically, the dust seal 180 is applied near the notch 114 in the vehicle side structure 100A as described above. The dust seal 180 is, for example, a strip-shaped member extending from the edge of the second region 118 of the outer panel flange 112 between the outer panel flange 112 and the reinforcing flange 132 (e.g., along...). Figure 1 The dustproof sealing line L1 shown is provided, thereby providing a dustproof seal between the edge of the second region 118 and the reinforcing flange 132 exposed from the notch 114 (as shown). Figure 5 (As shown). The dust seal 180 can be considered as being disposed at the intersection of the outer panel flange 112 and the glass seal 190 described later to form a flat surface. In cases where the side structure 100A of the vehicle body further incorporates components such as a windshield frame 104, the windshield frame 104 can be sealed by the dust seal 180. However, the specific structure, location, and whether or not the dust seal 180 is present can be adjusted according to requirements, and this invention is not limited thereto.

[0060] Furthermore, in other embodiments, such as Figure 1 and Figure 5 As shown, compared to the aforementioned vehicle side structure 100, the vehicle side structure 100A further includes a glass seal 190. The glass seal 190 is disposed on the outer panel flange 112 and at least partially overlaps with the dust seal 180. Specifically, the glass seal 190 is applied near the notch 114 in the vehicle side structure 100A as described above. The glass seal 190 is, for example, a strip-shaped member extending from the outer panel flange 112 (e.g., along...). Figure 1The glass sealing line L2 shown is provided, and protrudes from the outer flange 112 toward the notch 114 in a cross-sectional view, thereby further positioning itself on the dust seal 180 and at least partially overlapping with the dust seal 180 (e.g. Figure 5 (As shown). In particular, the glass seal 190 is further disposed between the windshield 106 disposed on the windshield frame 104 and the outer flange 112 of the outer panel 110. When the side structure 100A of the vehicle body further incorporates components such as the windshield frame 104 and the windshield 106, the windshield frame 104 and the windshield 106 can be sealed by the glass seal 190. However, the specific structure, placement, and whether or not the glass seal 190 is disposed can be adjusted according to requirements, and this utility model is not limited thereto.

[0061] In summary, in the vehicle body side structure of this utility model, the outer panel flange is provided with a notch, a first region, and a second region, and the flanges of the outer panel, inner panel, reinforcing member, and patch are joined by a first joint, a second joint, and a third joint. Specifically, the first joint joins the flanges of the outer panel, inner panel, and reinforcing member in the first region; the second joint joins the flanges of the outer panel and reinforcing member in the second region; and the third joint joins the flanges of the reinforcing member, patch, and inner panel in the third region corresponding to the notch. Thus, the first and third joints each only need to join the flanges of three components, and the second joint only needs to join the flanges of two components. Compared to a structure that joins the flanges of four components simultaneously through joints, the first, second, and third joints provide a better joining effect, allowing these components to be more securely connected as a whole. Preferably, the side structure of the vehicle body also includes dustproof seals and glass seals, and the thickness of each of the reinforcing member, inner panel, and patch is greater than the thickness of the outer panel, thereby further improving structural rigidity.
