Description

Technical Field

[0001] This application belongs to the field of automotive collision safety technology, specifically relating to an A-pillar structure and its vehicle. Background Technology

[0002] Small overlap collision refers to a collision in which only about 25% of the front part of the vehicle (usually the driver's or passenger's side) overlaps with the obstacle.

[0003] When a vehicle is involved in a minor collision, the energy-absorbing zone of the vehicle cannot collapse to absorb energy. Therefore, the A-pillar may bear a greater impact force, which increases the risk of the A-pillar cracking and seriously endangers the lives of the people inside the vehicle. Utility Model Content

[0004] The purpose of this application is to provide an A-pillar structure and its vehicle, which helps to reduce the risk of A-pillar cracking and thus protect the life safety of the occupants.

[0005] The first aspect of this application discloses an A-column structure, comprising: an A-column and a first reinforcing member, wherein the A-column has a cavity, and the A-column includes an inner plate and an outer plate disposed opposite to each other, the inner plate being connected to the outer plate; the first reinforcing member is located within the cavity, and the first reinforcing member includes an intersecting first reinforcing portion and a second reinforcing portion, the first reinforcing portion being connected to the second reinforcing portion, one end of the first reinforcing portion being connected to the inner plate, and the other end of the first reinforcing portion being connected to the outer plate; the second reinforcing portion being connected to the inner plate.

[0006] In one exemplary embodiment of this application, the inner panel includes a middle inner panel portion and a side inner panel portion.

[0008] In one exemplary embodiment of this application, the inner side panel includes a first side panel and a second side panel, and the middle inner panel is connected between the first side panel and the second side panel. The first side panel is used to connect with the vehicle's shotgun beam. The outer side panel includes a third side panel and a fourth side panel, and the middle outer panel is connected between the third side panel and the fourth side panel. The third side panel is used to connect with the vehicle's shotgun beam. One end of the first reinforcing part is connected to the first side panel, and the other end of the first reinforcing part is connected to the third side panel.

[0009] In one exemplary embodiment of this application, the second reinforcing part is provided with a first flange and a second flange, the first flange and the second flange are connected to two opposite sides of the second reinforcing part in a one-to-one correspondence, and both the first flange and the second flange are connected to the first reinforcing part and the inner plate.

[0010] In one exemplary embodiment of this application, the second reinforcing part is provided with a clearance groove, which is used to avoid the wiring harness mounting hole of the inner plate.

[0011] In one exemplary embodiment of this application, the first reinforcing part is provided with a first mounting hole, and the outer plate is provided with a second mounting hole, with the first mounting hole and the second mounting hole corresponding to each other; the A-column structure further includes a fastener, which passes through the first mounting hole and the second mounting hole to connect the first reinforcing part and the outer plate.

[0012] In one exemplary embodiment of this application, the A-column structure further includes a second reinforcing member located outside the cavity, one end of the second reinforcing member being connected to the inner plate, and the other end of the second reinforcing member being connected to the outer plate.

[0013] In one exemplary embodiment of this application, the cross-section of the second reinforcing member is "U"-shaped; and / or, the second reinforcing member is provided with reinforcing ribs.

[0014] A second aspect of this application discloses a vehicle including a shotgun beam and the aforementioned A-pillar structure, wherein the shotgun beam is connected to the A-pillar structure.

[0015] The proposed solution has the following beneficial effects:

[0016] In this embodiment, when a minor overlap collision occurs, since one end of the first reinforcing part is connected to the inner panel and the other end is connected to the outer panel, the first reinforcing part can increase the connection strength between the inner and outer panels, making it less likely for the outer panel to crack relative to the inner panel. This helps reduce the risk of cracking of the A-pillar, thus ensuring the safety of the occupants. Furthermore, since the second reinforcing part is connected to the first reinforcing part and the inner panel, the second reinforcing part can increase the connection strength between the first reinforcing part and the inner panel, making it less likely for the first reinforcing part to crack relative to the inner panel along with the outer panel. This ensures that the first reinforcing part can increase the connection strength between the inner and outer panels, thus helping to reduce the risk of cracking of the A-pillar, thus ensuring the safety of the occupants.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0033] like Figures 1 to 9 As shown, this embodiment provides an A-column structure, including: an A-column 1 and a first reinforcing member 2. The A-column 1 has a cavity 101. The A-column 1 includes an inner plate 11 and an outer plate 12 arranged opposite to each other along the thickness direction y of the A-column 1. The inner plate 11 and the outer plate 12 are connected. The first reinforcing member 2 is located inside the cavity 101. The first reinforcing member 2 includes an intersecting first reinforcing part 21 and a second reinforcing part 22. The first reinforcing part 21 and the second reinforcing part 22 are connected. One end of the first reinforcing part 21 is connected to the inner plate 11, and the other end of the first reinforcing part 21 is connected to the outer plate 12. The second reinforcing part 22 is connected to the inner plate 11.

[0034] In this embodiment, the inner plate 11 is connected to the outer plate 12 to form a cavity 101.

[0035] In this embodiment, when a minor collision occurs, since one end of the first reinforcing part 21 is connected to the inner panel 11 and the other end of the first reinforcing part 21 is connected to the outer panel 12, the first reinforcing part 21 can increase the connection strength between the inner panel 11 and the outer panel 12, making it less likely for the outer panel 12 to crack relative to the inner panel 11. This helps reduce the risk of cracking of the A-pillar 1, thus ensuring the safety of the occupants. Furthermore, since the second reinforcing part 22 is connected to both the first reinforcing part 21 and the inner panel 11, the second reinforcing part 22 can increase the connection strength between the first reinforcing part 21 and the inner panel 11, making it less likely for the first reinforcing part 21 to crack relative to the inner panel 11 along with the outer panel 12. This ensures that the first reinforcing part 21 can increase the connection strength between the inner panel 11 and the outer panel 12, thus helping to reduce the risk of cracking of the A-pillar 1, thus ensuring the safety of the occupants.

[0036] It should be understood that when a vehicle is involved in a minor overlap collision, it is mainly the outer panel 12 that collides with the obstacle, making the outer panel 12 prone to cracking relative to the inner panel 11, which in turn leads to cracking of the A pillar structure.

[0037] Combination Figure 3 and Figure 4As shown, the inner panel 11 includes a middle inner panel portion 111 and a side inner panel portion 112. The middle inner panel portion 111 and the outer panel 12 are arranged opposite each other along the thickness direction y of column A 1. The side inner panel portion 112 is connected between the middle inner panel portion 111 and the outer panel 12. One end of the first reinforcing part 21 is connected to the side inner panel portion 112, and the other end of the first reinforcing part 21 is connected to the outer panel 12. The second reinforcing part 22 is connected to the middle inner panel portion 111.

[0038] In this embodiment, one end of the first reinforcing part 21 is connected to the inner side panel 112, and the other end of the first reinforcing part 21 is connected to the outer panel 12. The first reinforcing part 21 can directly strengthen the connection between the inner side panel 112 and the outer panel 12, thereby increasing the connection strength between the inner panel 11 and the outer panel 12. This makes it less likely for the connection between the inner side panel 112 and the outer panel 12 to crack when the vehicle experiences a small overlap collision, which helps to reduce the risk of cracking of the A pillar 1 and ensure the safety of the occupants.

[0039] Furthermore, compared to the connection between the second reinforcing part 22 and the side inner panel part 112, the connection area between the second reinforcing part 22 and the middle inner panel part 111 is larger, which can further increase the connection strength between the first reinforcing part 21 and the inner panel 11. This makes it less likely for the first reinforcing part 21 to crack relative to the inner panel 11 at the same time as the outer panel 12, ensuring that the first reinforcing part 21 can increase the connection strength between the inner panel 11 and the outer panel 12. This helps to reduce the risk of cracking of the A pillar 1, so as to protect the life safety of the people inside the vehicle.

[0040] In other embodiments, one end of the first reinforcing part 21 may also be connected to the middle inner plate part 111, and the other end of the first reinforcing part 21 may be connected to the outer plate 12. The first reinforcing part 21 can also increase the connection strength between the inner plate 11 and the outer plate 12.

[0041] Combination Figures 3 to 7 As shown, the outer panel 12 includes a middle outer panel portion 121 and a side outer panel portion 122. The middle outer panel portion 121 and the middle inner panel portion 111 are arranged opposite each other along the thickness direction y of column A 1. The side outer panel portion 122 is connected to the side inner panel portion 112. One end of the first reinforcing part 21 is connected to the side outer panel portion 122, and the other end of the first reinforcing part 21 is connected to the side inner panel portion 112.

[0042] In this embodiment, one end of the first reinforcing part 21 is connected to the inner side panel 112, and the other end of the first reinforcing part 21 is connected to the outer side panel 122. The first reinforcing part 21 can directly strengthen the connection between the inner side panel 112 and the outer side panel 122, thereby increasing the connection strength between the inner panel 11 and the outer panel 12. This makes it less likely for the connection between the inner side panel 112 and the outer side panel 122 to crack when the vehicle experiences a small overlap collision, which helps to reduce the risk of cracking of the A pillar 1 and ensure the safety of the occupants.

[0043] Furthermore, since the middle outer panel 121 needs to be fitted with a door hinge, the first reinforcing part 21 is connected to the side outer panel 122 to avoid interference between the first reinforcing part 21 and the door hinge, thus facilitating the installation of the door hinge.

[0044] In other embodiments, one end of the first reinforcing part 21 is connected to the inner side plate 112, and the other end of the first reinforcing part 21 can also be connected to the middle outer plate 121. The first reinforcing part 21 can also increase the connection strength between the inner plate 11 and the outer plate 12.

[0045] In other embodiments, one end of the first reinforcing part 21 may also be connected to the middle inner plate part 111, and the other end of the first reinforcing part 21 may also be connected to the middle outer plate part 121. The first reinforcing part 21 can also increase the connection strength between the inner plate 11 and the outer plate 12.

[0046] Combination Figure 1 , Figure 4 and Figure 6 As shown, the inner side panel 112 includes a first side panel 1121 and a second side panel 1122, and a middle inner panel 111 is connected between the first side panel 1121 and the second side panel 1122. The first side panel 1121 is used to connect with the vehicle's shotgun beam 4. The outer side panel 122 includes a third side panel 1221 and a fourth side panel 1222, and a middle outer panel 121 is connected between the third side panel 1221 and the fourth side panel 1222. The third side panel 1221 is used to connect with the vehicle's shotgun beam 4.

[0047] In this embodiment, the first side plate 1121, the second side plate 1122, and the middle inner plate portion 111 are an integral structure, that is, the inner plate 11 is an integral structure. The third side plate 1221, the fourth side plate 1222, and the middle outer plate portion 121 are an integral structure, that is, the outer plate 12 is an integral structure.

[0048] It should be understood that shotgun beam 4 is the upper longitudinal beam of the vehicle's front compartment.

[0049] It should be understood that the first side plate 1121 is connected to the third side plate 1221, and the second side plate 1122 is connected to the fourth side plate 1222. Since the first side plate 1121 and the third side plate 1221 are used to connect to the vehicle's shotgun beam 4, when the vehicle is involved in a minor overlap collision, the first side plate 1121 and the third side plate 1221 will collide with the obstacle first, compared to the second side plate 1122 and the fourth side plate 1222, which will cause the connection between the first side plate 1121 and the third side plate 1221 to crack.

[0050] In this embodiment, one end of the first reinforcing part 21 is connected to the first side plate 1121, and the other end of the first reinforcing part 21 is connected to the third side plate 1221. The first reinforcing part 21 can increase the connection strength between the first side plate 1121 and the third side plate 1221, so that when the vehicle is involved in a small overlap collision, the connection between the first side plate 1121 and the third side plate 1221 is not easy to crack, which helps to reduce the risk of cracking of the A pillar 1 and protect the life safety of the people in the vehicle.

[0051] In other embodiments, the first reinforcing member 2 includes two first reinforcing portions 21. One end of one first reinforcing portion 21 is connected to the first side plate 1121, and the other end of the other first reinforcing portion 21 is connected to the third side plate 1221. One end of the other first reinforcing portion 21 is connected to the second side plate 1122, and the other end of the other first reinforcing portion 21 is connected to the fourth side plate 1222. One first reinforcing portion 21 can increase the connection strength between the first side plate 1121 and the third side plate 1221, and the other first reinforcing portion 21 can increase the connection strength between the second side plate 1122 and the fourth side plate 1222, further increasing the connection strength between the inner plate 11 and the outer plate 12.

[0052] In this embodiment, the first reinforcing part 21 is provided with a plurality of mutually spaced reinforcing ribs c. The reinforcing ribs c can improve the rigidity of the first reinforcing part 21, thereby helping to increase the connection strength between the first side plate 1121 and the third side plate 1221.

[0053] It should be understood that "multiple" refers to two or more quantities, such as two, three, four, etc.

[0054] Combination Figure 3 and Figure 4 As shown, the second reinforcing part 22 is provided with a first flange 221 and a second flange 222. The first flange 221 and the second flange 222 are connected one-to-one along the length direction z of column A 1 to the two opposite sides of the second reinforcing part 22. The first flange 221 and the second flange 222 are both connected to the first reinforcing part 21 and the inner plate 11.

[0055] In this embodiment, the first flange 221 and the second flange 222 are connected to the first reinforcing part 21 and the second reinforcing part 22. The first flange 221 and the second flange 222 can increase the rigidity of the first reinforcing member 2, so that the first reinforcing member 2 can further increase the connection strength between the inner panel 11 and the outer panel 12, thereby helping to reduce the risk of cracking of the A pillar 1 and ensuring the safety of the people inside the vehicle.

[0056] In addition, the first flange 221 and the second flange 222 are connected to the second side plate 1122, which further increases the connection strength between the first reinforcing member 2 and the inner plate 11, making it less likely for the first reinforcing member 2 to crack relative to the inner plate 11 at the same time as the outer plate 12, thereby ensuring that the first reinforcing member 2 can strengthen the connection strength between the inner plate 11 and the outer plate 12.

[0057] In this embodiment, the second reinforcing part 22 is provided with a first welding boss 223, a second welding boss 224, a third welding boss 225 and a fourth welding boss 226. The first welding boss 223, the second welding boss 224, the third welding boss 225 and the fourth welding boss 226 are all provided to protrude along the outer plate 12 toward the inner plate 11. The first welding boss 223, the second welding boss 224, the third welding boss 225 and the fourth welding boss 226 are used to weld with the middle inner plate part 111 of the inner plate 11 to ensure the connection strength between the first reinforcing member 2 and the inner plate 11.

[0058] Combination Figure 4 and Figure 8 As shown, the second reinforcing part 22 is provided with a relief groove 201, which is used to avoid the wire harness mounting hole 102 of the middle inner plate part 111.

[0059] In this embodiment, the middle inner plate portion 111 is provided with a wire harness mounting hole 102, which connects the inside and outside of the cavity 101 to facilitate the installation of the wire harness. The clearance groove 201 of the second reinforcing portion 22 can avoid the wire harness mounting hole 102, so as to prevent the arrangement of the wire harness in the A column 1 from being affected by the setting of the first reinforcing member 2.

[0060] Combination Figure 2 , Figure 3 and Figure 8 As shown, the first reinforcing part 21 is provided with a first mounting hole 202, and the outer plate 12 is provided with a second mounting hole 103. The first mounting hole 202 and the second mounting hole 103 are correspondingly provided. The A column structure also includes a fastener 5, which passes through the first mounting hole 202 and the second mounting hole 103 to connect the first reinforcing part 21 and the outer plate 12.

[0061] In this embodiment, the first reinforcing part 21 includes a first reinforcing section 211 and a second reinforcing section 212. The first reinforcing section 211 is connected to the first side plate 1121, the second reinforcing part 22, the first flange 221 and the second flange 222, and the second reinforcing section 212 is connected to the third side plate 1221.

[0062] It should be understood that the number of first mounting holes 202 is the same as the number of second mounting holes 103, and the number of first mounting holes 202 and second mounting holes 103 can be selected according to the actual situation.

[0063] For example, the number of first mounting holes 202 can be one, two, three, four, etc.; the number of second mounting holes 103 can be one, two, three, four, etc.

[0064] In this embodiment, the second reinforcing section 212 is provided with three mutually spaced first mounting holes 202, and the third side plate 1221 is provided with three mutually spaced second mounting holes 103. The three first mounting holes 202 and the three second mounting holes 103 are arranged in a one-to-one correspondence.

[0065] In this embodiment, the fastener 5 is a bolt. The A column structure includes three bolts, which pass through the three first mounting holes 202 and the three second mounting holes 103 respectively, so as to realize the connection between the second reinforcing section 212 and the third side plate 1221.

[0066] It should be understood that, since the first reinforcing member 2 located inside the cavity 101 cannot be welded to the outer plate 12 after the inner plate 11 is connected to the outer plate 12 and the cavity 101 is formed, the first reinforcing member 2 and the outer plate 12 need to be connected by bolts to achieve the connection between the first reinforcing member 2 and the outer plate 12.

[0067] In this embodiment, the first reinforcing member 2 is located at the middle position of the length direction z of the A column 1, which helps to prevent the middle part of the A column 1 from cracking, so as to ensure the safety of the people inside the vehicle.

[0068] It should be understood that the middle position is not limited to the exact middle position, but can also be the area near the middle position.

[0069] Combination Figure 1 , Figure 5 and Figure 6 As shown, the A column structure also includes a second reinforcing member 3, which is located outside the cavity 101. One end of the second reinforcing member 3 is connected to the first side plate 1121, and the other end of the second reinforcing member 3 is connected to the third side plate 1221.

[0070] In this embodiment, when a minor collision occurs, since one end of the second reinforcing member 3 is connected to the first side panel 1121 and the other end of the second reinforcing member 3 is connected to the third side panel 1221, the second reinforcing member 3 can increase the connection strength between the first side panel 1121 and the third side panel 1221, making the outer panel 12 less likely to crack relative to the inner panel 11, thereby helping to reduce the risk of cracking of the A pillar 1 and ensuring the safety of the occupants.

[0071] In this embodiment, the first side plate 1121, the second side plate 1122, the third side plate 1221, and the fourth side plate 1222 each include a plate surface segment a and a connecting segment b. The plate surface segment a of the first side plate 1121 is connected between the connecting segment b of the first side plate 1121 and the middle inner plate portion 111. The plate surface segment a of the second side plate 1122 is connected between the connecting segment b of the second side plate 1122 and the middle inner plate portion 111. The plate surface segment a of the third side plate 1221 is connected between the connecting segment b of the third side plate 1221 and the middle outer plate portion 121. The plate surface segment a of the fourth side plate 1222 is connected between the connecting segment b of the fourth side plate 1222 and the middle outer plate portion 121. The connecting segment b of the first side plate 1121 is connected to the connecting segment b of the third side plate 1221, and the connecting segment b of the second side plate 1122 is connected to the connecting segment b of the fourth side plate 1222.

[0072] It should be understood that the connection of the first reinforcing member 2 and the second reinforcing member 3 to the first side plate 1121, the second side plate 1122, the third side plate 1221, and the fourth side plate 1222 refers to the connection of the first reinforcing member 2 and the second reinforcing member 3 to the plate surface segment a of the first side plate 1121, the plate surface segment a of the second side plate 1122, the plate surface segment a of the third side plate 1221, and the plate surface segment a of the fourth side plate 1222.

[0073] In this embodiment, the cross-section of the second reinforcing member 3 is "U" shaped, that is, the second reinforcing member 3 is a "U" shaped structure. While ensuring that the second reinforcing member 3 can connect the plate surface segment a of the first side plate 1121 and the plate surface segment a of the third side plate 1221, the connecting segment b of the first side plate 1121 and the connecting segment b of the third side plate 1221 can also be avoided.

[0074] In this embodiment, the second reinforcing member 3 includes a first connecting portion 31, a middle reinforcing portion 32, and a second connecting portion 33. The middle reinforcing portion 32 is a "U" shaped structure. The middle reinforcing portion 32 is connected between the first connecting portion 31 and the second connecting portion 33. The first connecting portion 31 is connected to the plate surface segment a of the first side plate 1121, and the second connecting portion 33 is connected to the plate surface segment a of the third side plate 1221. The connecting segment b of the first side plate 1121 and the connecting segment b of the third side plate 1221 are located inside the middle reinforcing portion 32.

[0075] For example, the second reinforcing member 3 is a sheet metal part or a die-cast part.

[0076] In this embodiment, the middle reinforcing portion 32 is provided with reinforcing ribs d. The reinforcing ribs d can increase the rigidity and strength of the second reinforcing member 3, and further ensure that the second reinforcing member 3 can effectively increase the connection strength between the first side plate 1121 and the third side plate 1221, so as to reduce the risk of cracking of the A pillar 1.

[0077] In this embodiment, the second reinforcing member 3 is provided with a third mounting hole 301, a fourth mounting hole 302 and a fifth mounting hole 303 spaced apart from each other.
