[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] Reference below Figure 1-Figure 7 A body assembly 100 of a vehicle according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 7 As shown, the vehicle body assembly 100 according to the embodiment of the present utility model includes: a longitudinal beam 82 , an A-pillar 87 , a first connecting member 81 , a front wall panel 621 and a second connecting member 84 .

[0037] The longitudinal beam 82 includes a first longitudinal beam section 821 and a second longitudinal beam section 822. One end of the second longitudinal beam section 822 is connected to the first longitudinal beam section 821, and the other end of the second longitudinal beam section 822 is connected to the A-pillar 87. The second longitudinal beam section 822 is an arc-shaped section and is concave toward the inner side of the vehicle. Figure 1 The first connecting member 81 is at least partially located below the longitudinal beam 82, and the first connecting member 81 is connected to the longitudinal beam 82, the A-pillar 87, and the front panel 621; the first connecting member 81 and the front panel 621 together define a first cavity structure 88, and the first cavity structure 88 has an open end facing the outside of the vehicle, and the second connecting member 84 at least partially closes the open end.

[0038] As some embodiments of the present application, the longitudinal beam 82 may be an integrally formed part, or the longitudinal beam 82 may be a split part.

[0039] Among them, along the length direction of the body component 100 (i.e. Figure 1 The second longitudinal beam section 822 has two opposite ends, one end of which is connected to the first longitudinal beam section 821, and the other end is connected to the A-pillar 87. The second longitudinal beam section 822 is constructed as an arc section, that is, the second longitudinal beam section 822 is a curved arc structure, and the second longitudinal beam section 822 is recessed toward the inner side of the vehicle.

[0040] By connecting the second longitudinal beam section 822 between the first longitudinal beam section 821 and the A-pillar 87, when the vehicle collides head-on, part of the impact force can be transmitted to the A-pillar 87 through the first longitudinal beam section 821 and the second longitudinal beam section 822, so that the vehicle body assembly 100 can reliably withstand and transmit the collision energy. In addition, by configuring the second longitudinal beam section 822 as an arc section and making the second longitudinal beam section 822 concave toward the inside of the vehicle, the front wheels of the vehicle can be avoided.

[0041] Along the height direction of the vehicle body component 100 (ie Figure 1 In the Z direction shown in the figure, the first connecting member 81 is at least partially located below the longitudinal beam 82, that is, a part of the structure of the first connecting member 81 is located below the longitudinal beam 82, or the entire structure of the first connecting member 81 is located below the longitudinal beam 82.

[0042] The first connecting member 81 is connected to the longitudinal beam 82, and the first connecting member 81 is connected to the A-pillar 87. For example, the first connecting member 81 can be connected to the lower end of the A-pillar 87. In addition, the first connecting member 81 is connected to the front panel 621. As some embodiments of the present application, part of the first connecting member 81 can be located below the front panel 621.

[0043] As some embodiments of the present application, the connection method between the first connecting member 81 and the longitudinal beam 82, the A-pillar 87, and the front panel 621 can be but is not limited to bolt connection, welding, etc.

[0044] When the vehicle encounters a head-on collision, part of the impact force can be transmitted to the first connecting member 81 through the longitudinal beam 82, and then transmitted to the A-pillar 87 and the front panel 621 through the first connecting member 81, so that the body assembly 100 can reliably withstand and transmit the collision energy.

[0045] The first connecting member 81 and the front panel 621 together define a first cavity structure 88 , wherein the first cavity structure 88 has an open end that faces the outside of the vehicle, and the second connecting member 84 at least partially closes the open end.

[0046] That is, a part of the structure of the second connecting member 84 closes the open end, or the entire structure of the second connecting member 84 closes the open end. It should be explained that, since the first connecting member 81, the front panel 621, and the second connecting member 84 are all sheet metal parts, even if at least part of the open end of the second connecting member 84 is closed, it does not mean that the first cavity structure 88 is a completely closed cavity structure, and the first cavity structure 88 can still have a gap connected to the outside. When the vehicle encounters a head-on collision, the first cavity structure 88 can collapse to absorb the collision energy.

[0047] As some embodiments of this application, refer to Figure 1-Figure 7 As shown, the number of the longitudinal beams 82 can be set to two, along the width direction of the body component 100 (ie Figure 1The two longitudinal beams 82 can be arranged opposite to each other and spaced apart, and the number of the A-pillars 87, the first connecting members 81, and the second connecting members 84 can be set to two, the two A-pillars 87 and the two first connecting members 81 can be set in a one-to-one correspondence with the two longitudinal beams 82, the two second connecting members 84 can be set in a one-to-one correspondence with the two first connecting members 81, and the number of the front panel 621 can be set to one, and the two first connecting members 81 are connected to the front panel 621.

[0048] Therefore, the structural design of the body component 100 can be reasonable. When the vehicle encounters a head-on collision, the body component 100 can reliably withstand, transmit and absorb the collision energy, which can reduce the probability of passenger injury, thereby improving the safety performance of the vehicle.

[0049] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the first connecting member 81 includes a connecting section 811 and a connecting body 812 . One end of the connecting section 811 is connected to the longitudinal beam 82 , and the other end of the connecting section 811 is connected to the connecting body 812 . The connecting body 812 is connected to both the A-pillar 87 and the front panel 621 .

[0050] The first connecting member 81 may include a connecting section 811 and a connecting body 812. The connecting section 811 and the connecting body 812 may be separate parts, or the connecting section 811 and the connecting body 812 may be integrally formed parts. The connecting section 811 has two opposite ends, one end of which is connected to the longitudinal beam 82, and the other end is connected to the connecting body 812. As some embodiments of the present application, the connection between the connecting section 811 and the longitudinal beam 82 is located below the longitudinal beam 82.

[0051] As some embodiments of the present application, a portion of the edge of the connecting body 812 is connected to the A-pillar 87 , a portion of the edge of the connecting body 812 is connected to the front panel 621 , and the first connecting member 81 can define a first cavity structure 88 together with the front panel 621 .

[0052] By making the first connecting member 81 have a connecting section 811 and a connecting body 812, the longitudinal beam 82, the A-pillar 87 and the front panel 621 can be connected together through the first connecting member 81, so that the body assembly 100 can be more reliable and not easily deformed due to a collision. When the vehicle collides head-on, the body assembly 100 can reliably withstand, transmit and absorb the collision energy, thereby reducing the probability of passenger injury.

[0053] In some embodiments of the present invention, Figure 4As shown, the connecting body 812 includes a first sub-body 8121, a second sub-body 8122 and a third sub-body 8123. The first sub-body 8121 is connected to the connecting section 811 and the A-pillar 87, and the second sub-body 8122 and the third sub-body 8123 are connected between the first sub-body 8121 and the front panel 621.

[0054] The first connector 81 may include a connecting section 811 and a connecting body 812, and the connecting body 812 may be divided into a first sub-body 8121, a second sub-body 8122, and a third sub-body 8123. The first sub-body 8121, the second sub-body 8122, and the third sub-body 8123 may be separate parts, or the first sub-body 8121, the second sub-body 8122, and the third sub-body 8123 may be an integrally formed part.

[0055] The first sub-body 8121 is connected between the connecting section 811 and the A-pillar 87 , the second sub-body 8122 is connected between the first sub-body 8121 and the front panel 621 , and the third sub-body 8123 is connected between the first sub-body 8121 and the front panel 621 .

[0056] By making the connecting body 812 include a first sub-body 8121, a second sub-body 8122 and a third sub-body 8123, the connecting body 812 can be connected to the connecting section 811, the A-pillar 87 and the front panel 621 respectively, so that the longitudinal beam 82, the A-pillar 87 and the front panel 621 can be connected together, which is beneficial to improving the overall structural strength of the body assembly 100 and enables the body assembly 100 to reliably withstand, transmit and absorb collision energy.

[0057] In some embodiments of the present invention, Figure 4 As shown, along the first direction (ie Figure 1 The second sub-body 8122 is at least partially located at the rear side of the first sub-body 8121, along the second direction (ie, the X direction) of the vehicle body assembly 100. Figure 1 In the Y direction shown in the figure, at least a portion of the third sub-body 8123 is located on a side of the first sub-body 8121 away from the A-pillar 87.

[0058] The height direction of the vehicle body component 100 (i.e. Figure 1 The Z direction shown in FIG. 1 ), the first direction of the vehicle body component 100 (ie Figure 1 X direction shown), the second direction of the body component 100 (i.e. Figure 1 The Y direction shown in the figure) are perpendicular to each other.

[0059] The connecting body 812 can be divided into a first sub-body 8121, a second sub-body 8122 and a third sub-body 8123. As some embodiments of the present application, along the first direction (i.e. Figure 1 X direction shown), part of the structure of the second sub-body 8122 can be located behind the first sub-body 8121, or the entire structure of the second sub-body 8122 can be located behind the first sub-body 8121, and the second sub-body 8122 is connected between the first sub-body 8121 and the front panel 621.

[0060] As some embodiments of the present application, along the second direction (ie, Figure 1 In the Y direction shown in the figure), from the outside of the vehicle to the inside of the vehicle, the A-pillar 87, the first sub-body 8121, and the third sub-body 8123 can be arranged in sequence, the third sub-body 8123 is connected to the first sub-body 8121, and at least part of the third sub-body 8123 is arranged on the side of the first sub-body 8121 away from the A-pillar 87, that is, part of the structure of the third sub-body 8123 can be located on the side of the first sub-body 8121 away from the A-pillar 87, or the entire structure of the third sub-body 8123 can be located on the side of the first sub-body 8121 away from the A-pillar 87, and the third sub-body 8123 is connected between the first sub-body 8121 and the front panel 621.

[0061] As some embodiments of the present application, the first sub-body 8121, the second sub-body 8122 and the third sub-body 8123 can be separate parts, and the first sub-body 8121 and the connecting section 811 can be an integrally formed part. This arrangement can not only reduce the production difficulty of the first connecting part 81, but also reduce the assembly difficulty of the first connecting part 81 and the longitudinal beam 82, the A-pillar 87, and the front panel 621, which is conducive to reducing the assembly difficulty of the body assembly 100.

[0062] As some embodiments of the present application, the second sub-body 8122 and the third sub-body 8123 can be arranged along the height direction of the vehicle body component 100 (ie, Figure 1 The Z direction shown extends.

[0063] In some embodiments of the present invention, Figure 2 As shown, the second connecting member 84 is connected to the first connecting member 81 , the front panel 621 , the A-pillar 87 , and the longitudinal beam 82 .

[0064] The first connecting member 81 and the front panel 621 define a first cavity structure 88, the first cavity structure 88 has an open end, a part of the second connecting member 84 closes the open end, or the entire structure of the second connecting member 84 closes the open end. As a specific embodiment of the present application, Figure 2As shown, a portion of the second connecting member 84 closes the open end.

[0065] As some embodiments of the present application, the second connecting member 84 may be constructed as a thin-walled sheet metal member.

[0066] As some embodiments of the present application, along the height direction of the vehicle body component 100 (ie Figure 1 The upper end of the second connecting member 84 can be connected to the longitudinal beam 82, and the lower end of the second connecting member 84 can be connected to the first connecting member 81. Figure 1 The rear end of the second connecting member 84 is connected to the A-pillar 87. In addition, the edge of the front panel 621 can be connected to the middle of the second connecting member 84.

[0067] By connecting the second connecting member 84 to the first connecting member 81, the front panel 621, the A-pillar 87, and the longitudinal beam 82, and making the second connecting member 84 close the open end of the first cavity structure 88, the structural form of the body assembly 100 can be made reasonable, and the second connecting member 84 can participate in bearing and transmitting the frontal collision force, thereby improving the safety performance of the vehicle.

[0068] In some embodiments of the present invention, Figure 2 As shown, the second connecting member 84 is recessed toward the inner side of the vehicle.

[0069] As some embodiments of the present application, the second connecting member 84 may be recessed toward the inner rear of the vehicle. As some embodiments of the present application, the recessed amplitude of the second connecting member 84 is the same as the recessed amplitude of the second longitudinal beam section 822 .

[0070] Such an arrangement allows the second connecting member 84 and the second longitudinal beam section 822 to avoid the front wheels of the vehicle, thereby facilitating the installation of the front wheels of the vehicle and helping to reduce the difficulty of assembling the vehicle.

[0071] In some embodiments of the present invention, the vehicle body assembly 100 further includes a third connecting member, and, as Figure 4 and Figure 6 As shown, the front panel 621 has a height direction (i.e. Figure 1 The number of the first connecting members 81 is two, and the first connecting member 81 is provided along the second direction (ie, the Z direction) of the vehicle body component 100. Figure 1 The recessed portion 6213 is located between the two first connecting members 81 , and the third connecting member is connected between the two first connecting members 81 and covers part of the recessed portion 6213 .

[0072] Wherein, along the second direction of the vehicle body component 100 (i.e. Figure 1The two first connecting members 81 can be arranged opposite to each other and spaced apart, a third connecting member is arranged between the two first connecting members 81, and the front panel 621 has a recessed portion 6213, along the height direction of the body assembly 100 (i.e. Figure 1 The recessed portion 6213 is recessed upward, that is, the opening of the recessed portion 6213 faces downward, and the third connecting member covers part of the recessed portion 6213, that is, along the height direction of the vehicle body component 100 (i.e. Figure 1 The third connecting member is arranged corresponding to the recessed portion 6213 and covers a portion of the opening of the recessed portion 6213.

[0073] By connecting the third connector between the two first connectors 81, the two first connectors 81 can be connected together. When the impact force is transmitted to one of the first connectors 81, the impact force can be transmitted to the other first connector 81 through the third connector, thereby improving the impact resistance of the body assembly 100. In addition, by providing the front panel 621 with the recessed portion 6213, the modal strength of the front panel 621 can be improved. In addition, by providing the third connector corresponding to the recessed portion 6213, the structural design of the body assembly 100 can be made more reasonable, and the structural stability of the body assembly 100 can be improved.

[0074] In some embodiments of the present invention, Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the body assembly 100 further includes a middle channel 91, which is provided along the height direction (i.e. Figure 1 The middle channel 91 is located on one side of the front panel 621, and the third connecting member is located on the other side of the front panel 621. The middle channel 91 and the front panel 621 together define a second cavity structure 915, and the second cavity structure 915 corresponds to the recessed portion 6213.

[0075] The middle channel 91 is along the first direction (i.e. Figure 1 As some embodiments of the present application, along the second direction (i.e., the X direction) of the body component 100, Figure 1 The middle channel 91 is located in the middle of the front panel 621. The front panel 621 can be constructed as an arc-shaped structure as a whole.

[0076] Along the height direction of the vehicle body component 100 (ie Figure 1The front panel 621 has two opposite sides, the middle channel 91 is located on one side of the front panel 621, the third connecting member is located on the other side of the front panel 621, and the first connecting member 81 is also located on the other side of the front panel 621. The middle channel 91 and the front panel 621 can jointly define a second cavity structure 915.

[0077] For example, the middle channel 91 may be located on the side of the front panel 621 facing the passenger compartment and may be connected to the front panel 621, and the third connector and the first connector 81 may be located on the side of the front panel 621 away from the passenger compartment. This arrangement allows the body assembly 100 to have multiple cavity structures, thereby improving the crush energy absorption capacity of the body assembly 100, and by making the second cavity structure 915 correspond to the recessed portion 6213, when the collision force is transmitted to the second cavity structure 915 and / or the recessed portion 6213, the second cavity structure 915 and the recessed portion 6213 can share the collision force, thereby improving the safety performance of the vehicle.

[0078] As some embodiments of the present application, the middle channel 91 and the front panel 621 can be connected by welding.

[0079] In some embodiments of the present invention, the cross section of the longitudinal beam 82 is a closed cross section.

[0080] As some embodiments of the present application, the longitudinal beam 82 may include an inner beam plate and an outer beam plate, which may be connected by welding so that the cross-section of the longitudinal beam 82 is a closed cross-section. Such a setting can not only enhance the structural strength of the longitudinal beam 82, but also make the longitudinal beam 82 less likely to bend and deform, so that the longitudinal beam 82 can more reliably resist external stress. Moreover, such a setting can reduce the weight of the longitudinal beam 82, thereby reducing the overall weight of the body assembly 100, which is beneficial to the lightweight design of the vehicle.

[0081] In some embodiments of the present invention, Figure 6 As shown, the distance between the two ends of the second longitudinal beam section 822 is D1, which satisfies the relationship: 400 mm ≤ D1 ≤ 500 mm.

[0082] That is, the distance between the two ends of the second longitudinal beam section 822 can be any value between 400 mm and 500 mm, for example, D1 can be but not limited to 400 mm, 450 mm, 500 mm, etc. Such a setting can make the distance between the two ends of the second longitudinal beam section 822 reasonable, which is conducive to ensuring the structural strength of the second longitudinal beam section 822.

[0083] It should be explained that the distance between the two ends of the second longitudinal beam segment 822 is the minimum distance between the two ends of the second longitudinal beam segment 822 .

[0084] In some embodiments of the present invention, Figure 7 As shown, along the first direction (ie Figure 7 The distance between the end of the second longitudinal beam section 822 connected to the first longitudinal beam section 821 and the A-pillar 87 is D2, which satisfies the relationship: 530 mm ≤ D2 ≤ 630 mm.

[0085] That is, along the first direction (ie, Figure 7 The distance between the end of the second longitudinal beam segment 822 connected to the first longitudinal beam segment 821 and the A-pillar 87 may be any value between 530 mm and 630 mm. For example, the distance between the end of the second longitudinal beam segment 822 connected to the first longitudinal beam segment 821 and the A-pillar 87 may be, but is not limited to, 530 mm, 580 mm, 630 mm, etc.
