Description

Technical Field

[0001] This disclosure relates to the vehicle body structure. Background Technology

[0002] For example, as recorded in Japanese Patent Application Publication No. 2015-74390, the frame for the seat back of the rear seat of a vehicle is a rectangular frame. Summary of the Invention

[0003] It is worth noting that when the vehicle body stiffness is high, the vehicle's torsional stiffness and shear stiffness increase accordingly, thereby improving the vehicle's driving performance (e.g., steering handling and cornering performance). In view of this issue, this disclosure presents an example of a vehicle body structure.

[0004] The vehicle body structure of one embodiment of this disclosure preferably includes at least one of the following constituent elements.

[0005] That is, the constituent elements include: a vehicle body structure, which includes a vehicle body and a frame structure for a seat back connected to the vehicle body. In addition, the frame structure has a rectangular frame and a reinforcing part, which is configured to restrict the deformation of the frame in the width direction of the vehicle. The frame structure is connected to the vehicle body at the upper and lower ends of one end of the frame structure in the width direction and at the lower end of the other end of the frame structure in the width direction.

[0006] Therefore, the frame structure used for the seat back can function as a structural component to improve the rigidity of the vehicle body. Thus, the rigidity of the vehicle body can be improved without increasing the thickness of the vehicle body panels, changing the structure, or adding strut tower bars.

[0007] Furthermore, the increase in seat back dimensions due to the addition of reinforcement is negligible. Therefore, there is virtually no negative impact on the trunk or interior space. In other words, the aforementioned vehicle structure improves the vehicle's torsional and shear stiffness, enhancing its handling performance, while minimizing the negative impact on the trunk or interior space.

[0008] In addition, the vehicle body structure may have the following configuration, for example.

[0009] That is, the reinforcement is a beam in the form of a diagonal brace, which connects to the diagonal position of the frame.

[0010] Furthermore, the preferred reinforcement comprises the following components: a back plate, which is generally rectangular and covers the back of the frame; a first oblique reinforcing rib, which is disposed in the back plate near the first connecting portion, the first oblique reinforcing rib being a protrusion extending from the plate surface of the back plate along the thickness direction and extending in a direction inclined relative to the width direction and the vertical direction; and a second oblique reinforcing rib, which is disposed in the back plate at a diagonal position opposite to the first oblique reinforcing rib, the second oblique reinforcing rib being a protrusion extending from the plate surface of the back plate along the thickness direction and extending in a direction inclined relative to the width direction and the vertical direction.

[0011] Furthermore, the first connecting part refers to the connection between the upper side of one end of the frame in the width direction and the vehicle body. The second connecting part refers to the connection between the lower side of one end of the frame in the width direction and the vehicle body. The third connecting part refers to the connection between the lower side of the other end of the frame in the width direction and the vehicle body. Attached Figure Description

[0018] (First Embodiment)

[0019] <1. Overview of the vehicle body structure>

[0020] like Figure 1As shown, the vehicle body structure 1 of this embodiment includes components such as a vehicle body 2 and a frame structure 3 for a seat back connected to the vehicle body 2.

[0021] <Vehicle Body>

[0022] The vehicle body 2 is a component that forms the vehicle frame. The vehicle body 2 is a structural component made of metal, and it has a monocoque structure or a space frame structure (in this embodiment, a semi-monocoque structure).

[0023] <Frame Structure>

[0024] The frame structure 3 is a reinforcing component that forms the seat back for the rear seats. The frame structure 3 includes at least a frame 31 and a reinforcing part 32. The frame 31 is a rectangular frame-shaped reinforcing component that forms a rectangular closed curve.

[0025] The frame structure 3, that is, the frame 31, is connected to the vehicle body 2 at the upper and lower ends of one end in the width direction and the lower end of the other end in the width direction.

[0026] In the following text, the connection between the upper side of one end of the frame 31 in the width direction and the vehicle body 2 is designated as the first connection J1. The connection between the lower side of one end of the frame 31 in the width direction and the vehicle body 2 is designated as the second connection J2. The connection between the lower side of the other end of the frame 31 in the width direction and the vehicle body 2 is designated as the third connection J3.

[0027] <Strengthened Department>

[0028] The reinforcing part 32 is used to limit the frame 31 in the vehicle width direction ( Figure 1 The component that deforms in the left-right direction of the paper. In addition, the reinforcing part 32 in this embodiment is composed of a beam (brace) 32A in the shape of a diagonal brace, which connects to the diagonal position of the frame 31.

[0029] In addition, in this embodiment, the reinforcing part 32 connects the diagonal position of the frame 31 by connecting the first connecting part J1 and the third connecting part J3.

[0030] <2. Features of the vehicle body structure in this embodiment>

[0031] In the vehicle body structure 1 of this embodiment, the frame structure 3 for the seat back is connected to the vehicle body 2 at the first connecting part J1 to the third connecting part J3, and a reinforcing part 32 is provided on the frame 31.

[0032] Therefore, the frame structure 3 can function as a structural component to improve the rigidity of the vehicle body 2. Thus, the rigidity of the vehicle body can be improved without increasing the thickness of the plate material of the vehicle body 2, changing the structure, or adding support columns and towers.

[0033] Furthermore, the increase in seat back dimensions due to the addition of the reinforcing section 32 is negligible. Therefore, there is virtually no negative impact on the trunk or interior space. In other words, according to the aforementioned vehicle body structure 1, the torsional and shear stiffness of the vehicle can be improved, thus enhancing the vehicle's driving performance, while having virtually no negative impact on the trunk or interior space.

[0034] (Second Implementation)

[0035] like Figure 2 As shown, the reinforcing part 32 in this embodiment is composed of a back plate 32D, on which at least a first oblique reinforcing rib 32B and a second oblique reinforcing rib 32C are provided. The back plate 32D is a plate material in the shape of a generally rectangular plate, which covers the back of the frame 31.

[0036] The first oblique reinforcing rib 32B is a reinforcing rib provided in the back plate 32D near the first connecting part J1. The first oblique reinforcing rib 32B is a protrusion that protrudes from the surface of the back plate 32D along the thickness direction and extends in a direction that is oblique to the width direction and the vertical direction.

[0037] The second oblique reinforcing rib 32C is a reinforcing rib provided at a diagonal position opposite to the first oblique reinforcing rib 32B in the back plate 32D. The second oblique reinforcing rib 32C is a protrusion that extends from the surface of the back plate 32D along the thickness direction and extends in a direction that is oblique relative to the width direction and the vertical direction.

[0038] With the above structure, in this embodiment, the backplate 32D can also restrict the deformation of the frame 31 in the vehicle width direction, thereby improving the rigidity of the vehicle body. Furthermore, this not only improves the vehicle's driving performance but also minimizes the negative impact of reduced trunk or interior space.

[0039] (Other implementation methods)

[0040] In the first embodiment described above, the reinforcing part 32 is configured to connect the diagonal positions of the frame 31 in a manner that connects the first connecting part J1 and the third connecting part J3. However, this disclosure is not limited to this. That is, this disclosure may also employ a reinforcing part 32 that connects to a diagonal position opposite to the diagonal position.

[0041] In the second embodiment described above, a first oblique reinforcing rib 32B and a second oblique reinforcing rib 32C are respectively provided at positions close to the first connecting portion J1 and the third connecting portion J3. However, this disclosure is not limited to this. That is, this disclosure may also adopt, for example, a configuration in which the first oblique reinforcing rib 32B and the second oblique reinforcing rib 32C are respectively provided at diagonal positions opposite to the diagonal positions formed by the first connecting portion J1 and the third connecting portion J3.

[0042] In the second embodiment described above, a frame 31 is provided. However, this disclosure is not limited to this. That is, this disclosure may also employ a configuration in which, for example, a reinforcing rib is provided at the end of the back plate 32D to perform the function of the frame 31, thereby eliminating the need for the frame 31.

[0043] Furthermore, this disclosure is not limited to the embodiments described above, as long as it conforms to the spirit of the invention. Therefore, it can be a structure composed of at least two of the above embodiments, or it can be a structure that eliminates any one of the constituent elements illustrated in the above embodiments, or it can be a structure that eliminates any one of the constituent elements indicated by the symbols in the above embodiments.
