Description

Technical Field

[0001] The utility model relates to a vehicle structure, in particular to a vehicle superstructure. Background Art

[0002] In recent years, efforts to provide access to sustainable transportation systems that take into account vulnerable transportation users, such as the elderly, people with disabilities, and children, have intensified. To achieve this goal, research and development efforts are underway to further improve transportation safety and convenience through developments related to vehicle livability (e.g., passenger safety and comfort). However, within vehicle livability-related technologies, the structural strength of vehicle superstructures remains a challenge.

[0003] In prior art, such as that disclosed in Japanese Patent No. 6304066, a vehicle superstructure includes two front and rear roof reinforcements extending in the vehicle width direction, and two left and right roof arches extending in the vehicle fore-aft direction and positioned between the two front and rear roof reinforcements. The left and right roof arches are inclined outward in the vehicle width direction from the front to the rear, thereby enhancing the torsional rigidity of the vehicle body. However, this vehicle superstructure lacks a reinforcement structure in the central region between the left and right roof arches, resulting in low structural strength near the roof panel supported by the left and right roof arches. Therefore, there is a need to improve the vehicle superstructure to enhance the structural strength near the roof panel and thereby enhance the livability of vehicles equipped with this vehicle superstructure.

[0004] The present invention aims to solve the above-mentioned problem by improving the structural strength of the vicinity of the roof panel and further contributes to the development of a sustainable transportation system. Utility Model Content

[0006] The utility model provides a vehicle upper structure, comprising: a pair of side frames, which are spaced apart in the vehicle width direction and extend along the vehicle front-rear direction; a front frame and a rear frame, which are spaced apart in the vehicle front-rear direction and connect the pair of side frames in the vehicle width direction; a longitudinal beam, which extends in the vehicle front-rear direction and is connected between the front frame and the rear frame; and a roof panel, which is supported by the pair of side frames, the front frame and the rear frame, and the longitudinal beam and is arranged above, wherein the roof panel has a pair of reinforcing ribs extending along the vehicle front-rear direction, and the pair of reinforcing ribs are spaced apart in the vehicle width direction and are respectively located between the longitudinal beam and one of the pair of side frames.

[0007] In an embodiment of the present invention, the roof panel is bonded to the longitudinal beam by an adhesive, and the adhesive is extended along a pair of side edges of the longitudinal beam in the vehicle width direction.

[0008] In an embodiment of the present invention, the longitudinal beam is configured as an elongated plate-like structure extending in the vehicle front-rear direction, and a pair of side edges of the longitudinal beam in the vehicle width direction have a pair of side protrusions with a cap-shaped cross section.

[0009] In an embodiment of the present invention, the roof panel is bonded to the longitudinal beam by an adhesive, and the adhesive is extended along the top of the cap-shaped transverse section of the pair of side protrusions of the longitudinal beam.

[0010] In an embodiment of the present invention, a length of the roof panel in the vehicle front-rear direction is shorter than a width of the roof panel in the vehicle width direction.

[0011] In an embodiment of the present invention, a width of a front end portion of the roof panel in the vehicle width direction is longer than a width of a rear end portion of the roof panel in the vehicle width direction.

[0012] In an embodiment of the present invention, outer side ends of the pair of reinforcing ribs in the vehicle width direction extend along a pair of side portions of the roof panel in the vehicle width direction.

[0013] In an embodiment of the present invention, a distance between the pair of reinforcing ribs in the vehicle width direction gradually increases toward the front side in the vehicle front-rear direction.

[0014] In an embodiment of the present invention, a distance between a pair of side edges of the longitudinal beam in the vehicle width direction gradually increases toward the rear side in the vehicle front-rear direction.

[0015] In an embodiment of the present invention, the roof panel includes a pair of outer portions located on the outer sides of a pair of reinforcing ribs in the vehicle width direction, and a central portion located on the inner side of a pair of reinforcing ribs, each of the pair of reinforcing ribs has an inclined portion, and in a front perspective viewed from the front side, the inclined portion is inclined from the corresponding outer portion toward the central portion and toward the lower side in the up and down direction of the vehicle.

[0016] Based on the above, in the vehicle superstructure of the present invention, a pair of side frames are connected in the vehicle width direction via a front frame and a rear frame, and the front and rear frames are connected in the vehicle fore-aft direction via longitudinal beams extending in the vehicle fore-aft direction. Furthermore, a roof panel, supported by the pair of side frames, the front and rear frames, and the longitudinal beams, is provided above the vehicle, and includes a pair of reinforcing ribs spaced apart in the vehicle width direction and extending in the vehicle fore-aft direction. Furthermore, the pair of reinforcing ribs are located between the longitudinal beams and one of the pair of side frames. In this manner, the roof panel can be reinforced by the simple longitudinal beams and the pair of reinforcing ribs, thereby increasing the surface rigidity of the roof panel to resist pressure exerted on the roof panel by snow accumulation, car washing, and other conditions. Consequently, the vehicle superstructure of the present invention can enhance the structural strength near the roof panel, thereby improving the livability of a vehicle equipped with the vehicle superstructure.

[0049] Below, with reference to the attached Figure 1 The embodiments of the present invention are described below. Figure 1 This is a perspective schematic diagram of a vehicle superstructure according to an embodiment of the present invention. Figure 2 yes Figure 1 The three-dimensional schematic diagram of the vehicle superstructure shown in another perspective, Figure 3 yes Figure 2 The enlarged partial schematic diagram of the vehicle superstructure near the longitudinal beam is shown. Figure 4 yes Figure 1 A schematic top view of the vehicle superstructure is shown, Figure 5 yes Figure 1The following will be used with the front view of the vehicle superstructure. Figures 1 to 5 The specific structure of the vehicle upper structure 100 of the present invention is described, wherein the vehicle front-to-back direction X (equivalent to the length direction), the vehicle width direction Y (equivalent to the left-right direction), and the vehicle up-down direction Z (equivalent to the height direction) refer to the directions of the vehicle on the three axial directions of the XYZ coordinate axes when the vehicle upper structure 100 is applied to a vehicle not shown, so as to facilitate the description of the specific structure of the vehicle upper structure 100, but the present invention is not limited to this and it can be adjusted according to needs.

[0050] Please refer to Figure 1 and Figure 2 In this embodiment, the vehicle upper structure 100 includes a pair of side frames 110A, 110B, a front frame 120 and a rear frame 130, a longitudinal beam 140, and a roof panel 150 (in Figure 1 Shown in and Figure 2 (not shown in the figure). A pair of side frames 110A, 110B are spaced apart in the vehicle width direction Y and extend along the vehicle front-rear direction X. The front frame 120 and the rear frame 130 are spaced apart in the vehicle front-rear direction X and connect the pair of side frames 110A, 110B in the vehicle width direction Y. The longitudinal beam 140 extends in the vehicle front-rear direction X and is connected between the front frame 120 and the rear frame 130. The roof panel 150 is supported by the pair of side frames 110A, 110B, the front frame 120 and the rear frame 130, and the longitudinal beam 140 and is disposed above. The roof panel 150 has a pair of reinforcing ribs 160A, 160B extending along the vehicle front-rear direction X. The pair of reinforcing ribs 160A, 160B are spaced apart in the vehicle width direction Y and are respectively located between the longitudinal beam 140 and one of the pair of side frames 110A, 110B. For example, the reinforcement rib 160A is located between the longitudinal beam 140 and the side frame 110A, and the reinforcement rib 160B is located between the longitudinal beam 140 and the side frame 110B. However, the present invention does not limit the specific structure and size of the above components of the vehicle upper structure 100, which can be adjusted according to needs.

[0051] Specifically, in this embodiment, Figure 1 and Figure 2As shown, the pair of side frames 110A and 110B are, for example, each configured as a strip-like structure extending in the vehicle longitudinal direction X and spaced apart in the vehicle width direction Y. The front frame 120 and the rear frame 130 are, for example, each configured as a strip-like structure extending in the vehicle width direction Y and spaced apart in the vehicle longitudinal direction X, thereby connecting the pair of side frames 110A and 110B in the vehicle width direction Y. In this manner, the front frame 120 and the rear frame 130 define a support region between the pair of side frames 110A and 110B to support the roof panel 150 disposed above and extending in both the vehicle longitudinal directions X and Y. Furthermore, the longitudinal beam 140 is configured as an elongated plate-like structure extending in the vehicle longitudinal direction X and is connected between the front frame 120 and the rear frame 130 to further support the roof panel 150 within the aforementioned support region. Furthermore, the roof panel 150 is, for example, a flat plate-like structure extending in the vehicle longitudinal direction X and the vehicle width direction Y. A pair of reinforcing ribs 160A and 160B are, for example, strip-like structures formed on the surface of the roof panel 150 and extending in the vehicle longitudinal direction X. These ribs are located on opposite sides of the longitudinal member 140 in the vehicle width direction Y to further support the roof panel 150 in the aforementioned support region.

[0052] Through the above-described arrangement, in the vehicle upper structure 100 of the present embodiment, the pair of side frames 110A, 110B are connected in the vehicle width direction Y via the front frame 120 and the rear frame 130, and the front frame 120 and the rear frame 130 are connected in the vehicle front-rear direction X via the longitudinal beam 140 extending in the vehicle front-rear direction X. Furthermore, the roof panel 150, which is supported and disposed above the pair of side frames 110A, 110B, the front frame 120 and the rear frame 130, and the longitudinal beam 140, has a pair of reinforcing ribs 160A, 160B spaced apart in the vehicle width direction Y and extending in the vehicle front-rear direction X. Furthermore, the pair of reinforcing ribs 160A, 160B are respectively located between the longitudinal beam 140 and one of the pair of side frames 110A, 110B. In this manner, the roof panel 150 can be reinforced by the simple longitudinal beam 140 and the pair of reinforcing ribs 160A and 160B, thereby increasing the surface rigidity of the roof panel 150 to resist the pressure exerted on the roof panel by snow accumulation, car washing, etc. Consequently, the vehicle superstructure 100 can improve the structural strength near the roof panel 150, thereby enhancing the livability (e.g., passenger safety and comfort) of the vehicle equipped with the vehicle superstructure 100.

[0053] As an example, in this embodiment, if Figure 3As shown, longitudinal beam 140 is formed into an elongated plate-like structure extending in the vehicle longitudinal direction X. A pair of side edges 142a, 142b of longitudinal beam 140 in the vehicle width direction Y have a pair of side projections 144a, 144b that have a cap-like cross-section. The cap-like cross-section refers to a three-sided cap structure formed by connecting a top portion 144p1 with opposing side portions 144p2, 144p3. As a result, the pair of side projections 144a, 144b provided on the pair of side edges 142a, 142b of longitudinal beam 140 have a higher structural strength than the rest of longitudinal beam 140. In this manner, configuring the reinforcing longitudinal beam 140 as an elongated plate-like structure can reduce the height of the vehicle superstructure 100 in the vehicle vertical direction Z. This allows the vehicle superstructure 100 to be used in low-profile vehicles such as sports cars. Furthermore, by reducing the amount of protrusion of the longitudinal beam 140 into the vehicle interior (i.e., the lower side), the vehicle's design performance can be improved (i.e., increasing the margin for exterior design). Furthermore, providing a pair of side protrusions 144a, 144b, each having a cap-like cross-section, on a pair of side edges 142a, 142b of the longitudinal beam 140, which is configured as an elongated plate-like structure, can enhance the structural strength of the longitudinal beam 140. However, the present invention is not limited to the specific structure of the longitudinal beam 140, and it can be adjusted as needed.

[0054] Furthermore, in this embodiment, if Figures 1 to 3 As shown, the roof panel 150 is bonded to the side member 140 via an adhesive 170 (indicated by the dashed area). The adhesive 170 extends along the pair of side edges 142a and 142b of the side member 140 in the vehicle width direction Y. Furthermore, if the side member 140 is provided with a pair of side protrusions 144a and 144b, the roof panel 150 is bonded to the side member 140 via the adhesive 170 (indicated by the dashed area). The adhesive 170 extends along the tops 144p1 of the cap-shaped cross-sections of the pair of side protrusions 144a and 144b of the side member 140. The adhesive 170 is preferably a mastic adhesive, an elastic adhesive primarily composed of synthetic rubber, used for filling and bonding. Because mastic adhesives can be cured by heat without solvent, offering high durability and strong adhesion, they are often used to bond inner and outer panels of vehicle hoods or doors (for example, to enhance the strength of the outer panel and suppress noise caused by vibration). Thus, the roof panel 150 and the side rails 140 are bonded together using adhesive 170. The strip-shaped adhesive 170 enhances the surface rigidity of the roof panel 150 bonded to the side rails 140 and suppresses noise caused by vibration of the roof panel 150. However, the present invention does not limit the type or placement of adhesive 170, and it can be adjusted as needed.

[0055] In addition, in this embodiment, Figure 3 As shown, the distance D1 between the pair of side edges 142a, 142b of the longitudinal beam 140 in the vehicle width direction Y gradually increases toward the rear in the vehicle front-rear direction X. Specifically, when the longitudinal beam 140 is configured as an elongated plate, the longitudinal beam 140 has a substantially trapezoidal planar structure whose width gradually increases from the front to the rear in a top view. Therefore, the pair of side edges 142a, 142b of the longitudinal beam 140 extend obliquely from the front to the rear and from the inside to the outside. Furthermore, the distance D11 between the pair of side edges 142a, 142b at the front end 146 of the longitudinal beam 140 is smaller than the distance D12 between the pair of side edges 142a, 142b at the rear end 148 of the longitudinal beam 140. Consequently, the distance D1 between the pair of side edges 142a, 142b gradually increases from the front to the rear. Thus, when the vehicle superstructure 100 is used in a vehicle, the longitudinal beam 140 has a smaller dimension at the front end 146. This allows the longitudinal beam 140 to reinforce the roof panel 150 while also increasing the headroom for passengers within the vehicle. Specifically, the provision of the longitudinal beam 140 does not compromise the headroom for passengers when the vehicle superstructure 100 is used in a vehicle, causing them to feel oppressive, and can enhance the rearward reinforcement effect. However, the present invention is not limited to the specific structure of the longitudinal beam 140 (e.g., width variation), and it can be adjusted as needed.

[0056] Furthermore, in this embodiment, if Figure 4 As shown, the width W1 of the front end 152 of the roof panel 150 in the vehicle width direction Y is greater than the width W2 of the rear end 154 of the roof panel 150 in the vehicle width direction Y. In other words, when the roof panel 150 is a flat plate, it has a generally trapezoidal planar structure with a gradually decreasing width from the front to the rear in a top-down view. Therefore, a pair of reinforcing ribs 160A and 160B extending along the vehicle front-rear direction X are provided on the roof panel 150. These ribs 160A and 160B can divide the roof panel 150 into at least three regions of non-uniform shape. Providing uniformly shaped regions at regular intervals can lead to a situation where the resonant frequencies align, reducing noise and vibration (NV) performance. Therefore, by dividing the roof panel 150 into non-uniform regions using the pair of reinforcing ribs 160A and 160B, the surface rigidity of the roof panel 150 can be increased, thereby eliminating the situation where the resonant frequencies align, reducing NV performance, during the design phase. However, the present invention is not limited to the specific structure of the roof panel 150 (the relative relationship between the front end portion 152 and the rear end portion 154 ), which can be adjusted according to needs.

[0057] In addition, in this embodiment, Figure 4As shown, the length L of the roof panel 150 in the vehicle longitudinal direction X is shorter than the width W of the roof panel 150 in the vehicle width direction Y (e.g., between the width W1 of the front end portion 152 and the width W2 of the rear end portion 154 described above). Thus, the roof panel 150 of the vehicle superstructure 100 extends further in the vehicle width direction Y than in the vehicle longitudinal direction X, making it suitable for use in vehicles such as sports cars. Furthermore, since the length L of the roof panel 150 is shorter than its width W, the addition of longitudinal beams 140 extending in the vehicle longitudinal direction X and connecting to the front and rear frames 120 and 130 to the vehicle superstructure 100 allows the use of smaller (shorter) and lighter longitudinal beams 140 as reinforcement components, compared to the addition of cross beams (not shown) extending in the vehicle width direction Y and parallel to the front and rear frames 120 and 130. This can suppress the weight increase of the vehicle superstructure 100 and the vehicle equipped with the vehicle superstructure 100. However, the present invention is not limited to the specific structure of the roof panel 150 (relative relationship between the length L and the width W), which can be adjusted according to needs.

[0058] In addition, in this embodiment, Figure 4 As shown, outer side ends 162a, 162b of the pair of reinforcing ribs 160A, 160B in the vehicle width direction Y extend along the pair of side portions 156a, 156b of the roof panel 150 in the vehicle width direction Y. In other words, rather than forming the pair of reinforcing ribs 160A, 160B in the center region of the roof panel 150, the pair of reinforcing ribs 160A, 160B are preferably formed in regions of the roof panel 150 that are closer to the outer sides of the pair of side portions 156a, 156b of the roof panel 150, and a fixed distance is maintained between the outer side ends 162a, 162b of the pair of reinforcing ribs 160A, 160B and the pair of side portions 156a, 156b of the roof panel 150 when viewed from above the roof panel 150. As can be seen from this, the central region of the roof panel 150 between the pair of reinforcing ribs 160A and 160B can be reinforced by the longitudinal beam 140. However, the outer regions of the roof panel 150 can be reinforced by prioritizing the distance between the pair of reinforcing ribs 160A and 160B and the pair of side portions 156a and 156b of the roof panel 150. This improves the uniform surface rigidity of the outer regions of the roof panel 150, which are located further outward in the vehicle width direction Y than the pair of reinforcing ribs 160A and 160B. However, the present invention is not limited to the specific structure of the roof panel 150 (the positions of the pair of reinforcing ribs 160A and 160B), and these can be adjusted as needed.

[0059] Furthermore, in this embodiment, if Figure 4As shown, the spacing D2 between the pair of reinforcing ribs 160A and 160B in the vehicle width direction Y gradually increases toward the front side in the vehicle front-rear direction X. That is, in a top view of the roof panel 150, the pair of reinforcing ribs 160A and 160B extend obliquely from the front side to the rear side and from the outer side to the inner side, so that the spacing D21 between the pair of reinforcing ribs 160A and 160B at the front end portion 152 is greater than the spacing D22 between the pair of reinforcing ribs 160A and 160B at the rear end portion 154, and the spacing D2 between the pair of reinforcing ribs 160A and 160B gradually decreases from the front side to the rear side. Thus, when the vehicle superstructure 100 is used in a vehicle, the pair of reinforcing ribs 160A and 160B of the roof panel 150 are further apart (with a larger separation distance D21) at the front end portion 152. Therefore, the pair of reinforcing ribs 160A and 160B can reinforce the roof panel 150 while also increasing the headroom for passengers in the vehicle. In other words, the provision of the pair of reinforcing ribs 160A and 160B does not affect the headroom for passengers when the vehicle superstructure 100 is used in a vehicle, causing them to feel cramped. However, the present invention is not limited to the specific structure of the roof panel 150 (the locations of the pair of reinforcing ribs 160A and 160B), and such a structure can be adjusted as needed.

[0060] Furthermore, in this embodiment, if Figure 4 and Figure 5 As shown, the roof panel 150 includes a pair of outer portions 158a, 158b located on the outer sides of the pair of reinforcing ribs 160A, 160B in the vehicle width direction Y, and a central portion 159 located on the inner sides of the pair of reinforcing ribs 160A, 160B. The pair of reinforcing ribs 160A, 160B each have an inclined portion 164a, 164b, and in a front view (i.e., Figure 5In the vehicle vertical direction Z, the inclined portions 164a and 164b are inclined from the corresponding outer portions 158a and 158b toward the center portion 159 and downward in the vehicle vertical direction Z. Specifically, the inclined portion 164a of the rib 160A is inclined downward from the outer portion 158a toward the center portion 159, while the inclined portion 164b of the rib 160B is inclined downward from the outer portion 158b toward the center portion 159. As a result, the roof panel 150 is formed such that the outer portions 158a and 158b are located higher than the center portion 159 in the vehicle vertical direction Z near the pair of ribs 160A and 160B. In this manner, when the vehicle upper structure 100 is used in a vehicle, the pair of ribs 160A and 160B of the roof panel 150 correspond to the headroom above the passenger. Therefore, the pair of ribs 160A and 160B can reinforce the roof panel 150 while ensuring headroom above the passenger. However, the present invention is not limited to the specific structure of the roof panel 150 (the formation positions of the pair of reinforcing ribs 160A, 160B), which can be adjusted according to needs.

[0061] In summary, in the vehicle superstructure of the present invention, a pair of side frames are connected in the vehicle width direction by a front frame and a rear frame, and the front and rear frames are connected in the vehicle fore-aft direction by longitudinal beams extending in the vehicle fore-aft direction. A roof panel, supported by the pair of side frames, the front and rear frames, and the longitudinal beams, is provided with a pair of reinforcing ribs spaced apart in the vehicle width direction and extending in the vehicle fore-aft direction. The pair of reinforcing ribs are located between the longitudinal beams and one of the pair of side frames. In this manner, the roof panel is reinforced by the simple longitudinal beams and the pair of reinforcing ribs, thereby increasing the surface rigidity of the roof panel to resist pressure exerted on the roof panel by, for example, snow accumulation and car washing. Preferably, the roof panel is bonded to the longitudinal beams with an adhesive, further increasing the surface rigidity of the roof panel to resist pressure exerted on the roof panel. Consequently, the vehicle superstructure of the present invention can enhance the structural strength near the roof panel, thereby improving the livability of a vehicle equipped with the vehicle superstructure.
