Description

Technical Field

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

[0002] Special Purpose Vehicles (PBVs) are vehicles designed to meet the market trend of diversified, small-batch production. They consist of a drive module for driving the vehicle and a living module for creating passenger and cargo spaces in various shapes that meet market requirements.

[0003] Therefore, PBV offers the advantage of being able to quickly produce vehicles that meet market requirements simply by changing the living modules.

[0004] To improve the utilization of space for passengers or cargo (such as luggage space) and reduce production costs, PBVs are designed to minimize the overall length of the vehicle while extending the wheelbase and placing the driver's seat as forward as possible.

[0005] Due to the aforementioned development trends, it is difficult to ensure sufficient space on the front side of the PBV to prepare for a frontal collision.

[0006] The above description of the background technology is intended only to help understand the background of the present invention, and does not mean that the present invention falls within the scope of related technologies known to those skilled in the art. Summary of the Invention

[0007] The present invention is proposed to address these issues and aims to provide a vehicle body structure in which, in order to maximize the interior space of vehicles such as PBVs, the first-row seats, including the driver's seat, are positioned as far forward as possible within the vehicle body (e.g., at the front of the vehicle body). This ensures that even in vehicles where sufficient space at the front of the vehicle body is difficult to guarantee for absorbing collision energy in a frontal collision, the collision energy generated by a frontal collision can be effectively dispersed and supported, thereby ensuring sufficient safety performance in preparation for a frontal collision.

[0008] The technical problems to be solved by the present invention are not limited to those mentioned above, and those skilled in the art can clearly understand other technical problems not mentioned above from the following description.

[0009] To achieve the above objectives, the present invention provides a vehicle body structure. In one embodiment, the vehicle body structure includes a front bulkhead comprising an inclined portion extending forward and upward from the floor, and an upright portion extending upward from the inclined portion. The vehicle body structure further includes: a front side beam disposed on both sides of the front portion of the vehicle body and extending in the longitudinal direction of the vehicle body; and a suspension support beam disposed above the front side beam, configured to support a suspension device, and rearwardly supported on the inclined portion. The vehicle body structure further includes an inclined upper longitudinal beam configured to support the rear portion of the suspension support beam, configured to overlap with the suspension support beam sandwiching the inclined portion, and extending in the longitudinal direction along the inclination of the inclined portion.

[0010] In one embodiment, the vehicle body structure further includes a side support longitudinal beam configured to support the rear portion of the front side beam. The rear portion of the front side beam may be coupled to the inclined portion, and the side support longitudinal beam may overlap with the front side beam sandwiching the inclined portion and extend in the longitudinal direction along the inclination of the inclined portion.

[0011] In one embodiment, the vehicle body structure further includes a front upper crossbeam disposed at the boundary between the upright and inclined portions of the front bulkhead and configured to extend in the lateral direction of the vehicle body. The front upper crossbeam may be configured to overlap with the suspension support beam sandwiching the front bulkhead to support the rear upper side of the suspension support beam.

[0012] The body structure may also include a front bulkhead center crossbeam, which is rearwardly and downwardly spaced from the front bulkhead upper crossbeam, extends in the lateral direction of the body, and is joined to the inclined portion, wherein the inclined upper longitudinal beam is configured to connect the front bulkhead upper crossbeam and the front bulkhead center crossbeam.

[0013] The front crossbeam can be configured to overlap with the inclined portion sandwiched between the upper rear sides of the front side beam to support the rear part of the front side beam.

[0014] In one embodiment, the vehicle body structure further includes a plurality of inclined lower longitudinal beams that can be connected to the front bulkhead crossbeam, extend longitudinally along the inclination of the inclined portion, and connect from the front bulkhead crossbeam to the floor.

[0015] The front crossbeam and multiple inclined lower longitudinal beams can be formed as a single unit.

[0016] Multiple inclined lower longitudinal beams can be arranged in two pairs on the side based on the lateral center of the vehicle body (i.e., two on one side and two on the other side), and the side support longitudinal beams can be arranged between the two inclined lower longitudinal beams on either side based on the lateral center of the vehicle body.

[0017] The rear end of the side support longitudinal beam can be connected to and supported by the front lower crossbeam, which is configured to extend in the lateral direction of the vehicle body and to connect two adjacent inclined lower longitudinal beams.

[0018] In one embodiment, the vehicle body structure also includes a seat mounting beam that can be connected to the rear end of each inclined lower longitudinal beam and extends in the longitudinal direction of the vehicle body.

[0019] The front hood crossbar can be attached to the upper side of the front bulkhead crossbeam and extends in the lateral direction of the vehicle body, and both ends of the front hood crossbar can be attached to the A-pillar.

[0020] The front hood crossbar, the front bulkhead center crossbeam, and the A-pillar can form a ring structure facing the front of the vehicle.

[0021] The front hood crossbar can be connected to the front bulkhead center crossbar via at least one front hood support beam, which is configured to connect the front hood crossbar and the front bulkhead center crossbar vertically and support the front hood crossbar and the front bulkhead center crossbar.

[0022] An additional inclined upper longitudinal beam may also be provided between the two inclined upper longitudinal beams, which extends longitudinally along the inclination of the inclined portion to connect the upper front crossbeam and the middle front crossbeam.

[0023] The additional inclined upper longitudinal beam can be aligned and set on the front upper side of two inclined lower longitudinal beams that are close to the lateral center of the vehicle body among multiple inclined lower longitudinal beams.

[0024] An additional front bulkhead crossbeam, having a shape that extends laterally toward the outside of the vehicle body between the upper front bulkhead crossbeam and the middle front bulkhead crossbeam, can be connected to each of the two inclined upper longitudinal beams.

[0025] The inclined upper longitudinal beam can be combined to extend and overlap with the upper side of the side support longitudinal beam, and the rear of the front side beam can be constructed as a double closed section support formed by the side support longitudinal beam and the inclined upper longitudinal beam.

[0026] The suspension support beam can be formed in an "n" shape, with both ends joined together to be spaced apart from the front beam in the longitudinal direction.

[0027] The suspension support beam may include: a first leg, the lower end of which is coupled to a front side beam; a second leg, the lower end of which is coupled to a front side beam at the rear of the first leg; and a leg connection that extends in the longitudinal direction of the vehicle body and is configured to connect the upper ends of the first leg and the second leg.

[0028] The suspension support beam can be attached to the wheel arch plate, so that the leg connection, the second leg and the first leg of the suspension support beam are connected to each other, thereby creating a space between the suspension support beam and the wheel arch plate.

[0029] According to the present invention, in order to maximize the interior space of vehicles such as PBVs, the first row of seats, including the driver's seat, is positioned as far forward as possible on the front side of the vehicle body. This ensures that even in vehicles where it is difficult to ensure sufficient space on the front side of the vehicle body for absorbing collision energy in the event of a frontal collision, the collision energy generated by a frontal collision can be effectively dispersed and supported, thereby providing sufficient safety performance to prepare for a frontal collision of the vehicle.

[0030] The effects obtained by the present invention are not limited to those mentioned above, and those skilled in the art will clearly understand from the following description other effects not mentioned above. Attached Figure Description

[0056] In the following description, the embodiments disclosed herein are illustrated in detail with reference to the accompanying drawings. Identical or similar constituent elements are given the same reference numerals, and repeated descriptions thereof are omitted.

[0057] Reference Figures 1 to 14 In an embodiment of the present invention, the vehicle body structure includes: a front bulkhead 7, including an inclined portion 3 extending forward and upward from the floor 1 and an upright portion 5 extending upward from the inclined portion 3; a front side beam 9, disposed on both sides of the front of the vehicle body and extending in the longitudinal direction of the vehicle body; a suspension support beam 11, disposed on the upper side of the front side beam 9, configured to support the suspension device, and rear supported on the inclined portion 3; and an inclined upper longitudinal beam 13, configured to support the rear of the suspension support beam 11, disposed to overlap the inclined portion 3 with the suspension support beam 11, and extending in the longitudinal direction along the inclination of the inclined portion 3.

[0058] In one embodiment, the rear portion 12 of the suspension support beam 11 is supported on the inclined portion 3 of the front bulkhead 7, and the inclined upper longitudinal beam 13 is installed to overlap with the inclined portion 3 sandwiched between the suspension support beam 11, thereby effectively supporting the impact force transmitted rearward through the suspension support beam 11 in the event of a frontal collision or other accidents involving the vehicle.

[0059] The front panel 7 can be formed by bending a panel or connecting multiple panels to form the inclined part 3 and the upright part 5.

[0060] In one embodiment, the suspension support beam 11 is formed as an "n" shape with both ends spaced apart from and joined to the front beam 9 in the longitudinal direction.

[0061] More specifically, the suspension support beam 11 may include: a first leg 15, the lower end of which is connected to the front side beam 9; a second leg 17, the lower end of which is connected to the front side beam 9 on the rear side of the first leg 15; and a leg connecting portion 19, which extends in the longitudinal direction of the vehicle body and is configured to connect the upper ends of the first leg 15 and the second leg 17.

[0062] The suspension support beam 11 is connected to the wheel cover plate 21, so that the leg connection portion 19, the second leg portion 17 and the first leg portion 15 of the suspension support beam 11 are connected to each other, thereby forming a space between the suspension support beam 11 and the wheel cover plate 21.

[0063] Therefore, the suspension support beam 11 together with the wheel arch plate 21 forms a cross-section that includes space extending from the first leg 15 to the second leg 17, so that the suspension support beam 11 can be used as a structure with high rigidity.

[0064] For reference, the suspension support beam 11 can support the shock absorbers of a double wishbone type suspension device.

[0065] The rear part 10 of the front side beam 9 is joined to the inclined part 3. A side support longitudinal beam 23 is also provided to support the rear part of the front side beam 9, and is configured to overlap with the inclined part 3 sandwiched by the front side beam 9, and extend in the longitudinal direction along the inclination of the inclined part 3.

[0066] In other words, the rear part 10 of the front side beam 9 can be firmly supported by the side support longitudinal beam 23 and the inclined part 3 of the front bulkhead 7, and is configured to effectively support the impact force transmitted through the front side beam 9 in the event of a frontal collision of the vehicle.

[0067] The upper front beam 25 is located at the boundary between the upright portion 5 and the inclined portion 3 of the front bulkhead 7, and extends in the lateral direction of the vehicle body. The upper front beam 25 is constructed and installed to overlap with the suspension support beam 11 sandwiching the front bulkhead 7, so as to support the rear upper side of the suspension support beam 11.

[0068] In other words, a front bulkhead upper crossbeam 25 is mounted on the rear side of a portion of the suspension support beam 11 to which the leg connection 19 and the second leg 17 are connected, and the front bulkhead 7 is located between the two. The front bulkhead upper crossbeam 25 is configured to support the impact force transmitted rearward through the suspension support beam 11 and to prevent the inclined portion 3 of the front bulkhead 7 from lifting upward.

[0069] In one embodiment, the front bulkhead middle crossbeam 27 is positioned rearward and downwardly spaced from the front bulkhead upper crossbeam 25, extends in the lateral direction of the vehicle body, and is connected to the inclined portion 3. The inclined upper longitudinal beam 13 is mounted to connect the front bulkhead upper crossbeam 25 and the front bulkhead middle crossbeam 27.

[0070] In addition, the front crossbeam 27 is configured to overlap with the inclined portion 3 sandwiched between the rear upper side of the front side beam 9 to support the rear part of the front side beam 9.

[0071] In addition, multiple inclined lower longitudinal beams 29 are connected to the front bulkhead middle crossbeam 27, extend longitudinally along the inclination of the inclined portion 3, and are connected from the front bulkhead middle crossbeam 27 to the floor 1.

[0072] In this case, the front crossbeam 27 and multiple inclined lower longitudinal beams 29 can be integrally formed.

[0073] In other words, the front crossbeam 27 and the multiple inclined lower longitudinal beams 29 can be manufactured into the shape of a single component using a single mold.

[0074] In the event of a frontal collision, the front bulkhead middle crossbeam 27 and multiple inclined lower longitudinal beams 29, together with the front bulkhead upper crossbeam 25, effectively suppress the deformation of the inclined portion 3 of the front bulkhead 7 when it is lifted upward by the impact force input rearward through the front side beam 9 and the suspension support beam 11.

[0075] In this embodiment, a plurality of inclined lower longitudinal beams 29 may be arranged in pairs (e.g., two on each side) on both sides based on the lateral center of the vehicle body. On either side based on the lateral center of the vehicle body, a side support longitudinal beam 23 is arranged between two inclined lower longitudinal beams 29.

[0076] In addition, the rear end of the side support longitudinal beam 23 has a structure that connects to and is supported by the front lower crossbeam 31, which is mounted to extend in the lateral direction of the vehicle body and is configured to connect two adjacent inclined lower longitudinal beams 29.

[0077] Therefore, the impact force transmitted rearward through the front side beam 9 is supported by the front bulkhead 7 and the side support longitudinal beams 23. Two inclined lower longitudinal beams 29 support the front bulkhead 7 on both sides of the periphery of the side support longitudinal beams 23, and the rear end of the side support longitudinal beams 23 is connected to the lower front bulkhead crossbeam 31. As a result, the side support longitudinal beams 23, as well as the inclined lower longitudinal beams 29 and the lower front bulkhead crossbeam 31 arranged around the side support longitudinal beams 23, can effectively disperse and support the impact force transmitted through the front side beam 9.

[0078] In one embodiment, a seat mounting beam 33 extending in the longitudinal direction of the vehicle body may be connected to the rear end of each inclined lower longitudinal beam 29.

[0079] Therefore, under normal conditions, the inclined lower longitudinal beam 29 connected to the seat mounting beam 33 helps ensure the rigidity required for seat installation. In the event of an accident such as a frontal collision, the seat mounting beam 33 disperses the impact force transmitted through the inclined lower longitudinal beam 29 to the floor 1 and the seat, thereby ensuring higher support rigidity.

[0080] Reference Figure 13 and Figure 14 The front hood crossbar 35 is attached to the upper side of the front bulkhead central crossbeam 27 and extends in the lateral direction of the vehicle body. Both ends of the front hood crossbar 35 are attached to the A-pillar 37.

[0081] In other words, the front hood crossbar 35, the front bulkhead central crossbeam 27, and the A-pillar 37 form a ring structure A facing the front of the vehicle.

[0082] Therefore, the annular structure A formed by connecting the front hood crossbar 35, the front bulkhead middle crossbeam 27 and the A-pillar 37 can provide high rigidity for supporting the front bulkhead middle crossbeam 27 downward, thereby more effectively suppressing the deformation of the front bulkhead 7 when it is lifted backward by the impact force input to the rear through the side beams and suspension support beams 11 in the event of a frontal collision.

[0083] In addition, the ring structure A can greatly help ensure the rigidity of the front of the vehicle body and ensure the structural rigidity that can effectively support the impact force even in the event of a side collision.

[0084] For reference, the steering column can be fixed to the front cover crossbar 35.

[0085] In one embodiment, the front cover crossbar 35 is connected to the front cover middle crossbar 27 via at least one front cover support beam 39, the front cover support beam 39 being configured to connect the front cover crossbar 35 and the front cover middle crossbar 27 vertically and support the front cover crossbar 35 and the front cover middle crossbar 27.

[0086] Therefore, when the impact force transmitted rearward from a frontal collision accident of the vehicle exerts a force that lifts the front bulkhead 7 upward, the front support beam 39 is used to press the front bulkhead 7 downward, thereby more effectively suppressing the front bulkhead 7 from lifting upward.

[0087] In another embodiment of the invention, such as by modification Figure 11 Formed Figure 15 As shown, an additional inclined upper longitudinal beam 41 can also be provided between the two inclined upper longitudinal beams 13, and it extends in the longitudinal direction along the inclination of the inclined portion 3 to connect the front upper crossbeam 25 and the front middle crossbeam 27.

[0088] In this case, the additional inclined upper longitudinal beam 41 can be aligned and set on the front upper side of two inclined lower longitudinal beams 29 that are close to the lateral center of the vehicle body.

[0089] This construction is used to additionally ensure the rigidity of the central part of the front bulkhead 7 and further reduce the deformation of the front bulkhead 7 in the event of a frontal collision or other accidents.

[0090] An additional front bulkhead crossbeam 43, which extends laterally toward the outside of the vehicle body between the upper front bulkhead crossbeam 25 and the middle front bulkhead crossbeam 27, is connected to each of the two inclined upper longitudinal beams 13, so that in the event of a frontal collision or similar accident, the additional front bulkhead crossbeam 43 can also disperse and support the impact force transmitted rearward.

[0091] Figure 16 It is along Figure 11 The cross-sectional view is taken along line F16-F16 and shows the side support longitudinal beam 23 mounted behind the front side beam 9. The rear end of the inclined upper longitudinal beam 13 is connected to the front bulkhead crossbeam 27, but not directly to the side support longitudinal beam 23.

[0092] Figure 17 Showing how to modify Figure 16 Another embodiment of the present invention is formed by the structure in the middle.

[0093] exist Figure 17 In the middle, the inclined upper longitudinal beam 13 is combined to extend and overlap the upper side of the side support longitudinal beam 23, and the rear part of the front side beam 9 is constructed to be a double closed section support formed by the side support longitudinal beam 23 and the inclined upper longitudinal beam 13.

[0094] This construction provides greater rigidity to resist impact forces transmitted rearward through the front side beam 9 and more effectively prevents the front bulkhead 7 from lifting upward.

[0095] While specific embodiments of the invention have been shown and described, it will be clear to those skilled in the art that various modifications and alterations can be made to the invention without departing from the technical spirit of the invention as defined in the appended claims.
