Therefore, they should not be construed as limitations on this application.

[0028] Embodiments of this application provide a mounting assembly for a vehicle pillar and door sill, referring to... Figures 1-4 It includes the inner panel of the pillar 1, the door sill 2, and the first reinforcing structure 3. Here, the vehicle pillar can refer to any one of the A-pillar, B-pillar, and C-pillar of the vehicle. The following description will mainly take the A-pillar as an example.

[0029] Those skilled in the art will understand that a vehicle pillar is typically formed by joining an inner pillar plate 1 and an outer pillar plate (not shown) along the width of the vehicle, wherein the inner pillar plate 1 is located on the side closer to the interior of the passenger compartment.

[0030] In this embodiment, the inner support plate 1 specifically includes a body 11 and a first folded wall 12 connected to one side of the body 11 along a first direction. A threshold 2 is connected to the first folded wall 12 along one side of the first direction, and to the body 11 along one side of the second direction. The first and second directions intersect here, and both are perpendicular to the height direction of the inner support plate 1.

[0031] As an example, the first direction, the second direction, and the height direction of the inner plate 1 of the pillar are perpendicular to each other. The first direction is parallel to the front-rear direction of the vehicle, the second direction is parallel to the width direction of the vehicle, and the height direction of the inner plate 1 of the pillar is parallel to the height direction of the vehicle.

[0032] The first folding wall 12 is specifically connected to the side of the main body 11 facing the current collision source. Taking the vehicle pillar as A-pillar as an example, the first folding wall 12 is connected to the front side of the main body 11. Taking the vehicle pillar as C-pillar as an example, the first folding wall 12 is connected to the rear side of the main body 11. Taking the vehicle pillar as B-pillar as an example, the first folding wall 12 can be connected to the front side or the rear side of the main body 11, which can be specifically determined according to the actual vehicle body design and usage requirements.

[0033] The body 11 and the first folded wall 12 of the inner plate 1 of the support column can be generally plate-shaped structures. The body 11 and the first folded wall 12 can be formed as an integral structure, or they can be connected by welding, FDS connection (Flow Drill Screw), bolt connection, SPR connection (Self-Piercing Rivet) or any other method that can meet the connection strength requirements. There are no restrictions on this.

[0034] Threshold 2 is generally a beam-like structure extending along the first direction. As an example, threshold 2 is an aluminum structure, but it can also be made of any other suitable material.

[0035] The threshold 2 is connected to the first folded wall 12 on one side of the first direction. The connection method at this location may include one or more of welding, FDS connection, and SPR connection.

[0036] It should be noted that various connection methods for the relevant components are provided here and in the relevant sections below. In specific applications, those skilled in the art can determine which connection method(s) to choose based on actual process requirements, connection strength requirements, production assembly difficulty and cost, or any other suitable connection method other than those provided in this application.

[0037] The threshold 2 is connected to the body 11 on one side surface along the second direction. Similarly, the connection method here may include one or more of welding, FDS connection, and SPR connection.

[0038] The first reinforcing structure 3 is disposed on the top side of the threshold 2. The first reinforcing structure 3 connects to the first folding wall 12 on one side and to the top surface 2a of the threshold 2 on the other side. The specific structural form of the first reinforcing structure 3 is not limited, as long as it can connect with the first folding wall 12 and the top surface 2a of the threshold 2.

[0039] It is understandable that if the first reinforcing structure 3 is not set, the part of the first folding wall 12 located on the top side of the sill 2 will be relatively weak due to the lack of support along the first direction, and there is a greater risk of tearing and instability. Once tearing and instability occur, it may lead to insufficient support of the lower structure of the vehicle pillar, which may intrude into the survival space of the chassis structure.

[0040] Taking the A-pillar as an example, in the event of a frontal collision (especially a small overlap frontal collision), the impact force will be transmitted to the first folding wall 12 first, and then generally along the first direction to the rear structure. If the first reinforcing structure 3 is not provided, the part of the first folding wall 12 located on the top side of the sill 2 will become a weak zone due to the lack of a reliable supporting structure behind it. This weak zone has a greater risk of tearing and instability during a collision. Once tearing and instability occur, it may lead to insufficient support for the lower section of the A-pillar structure, which may intrude into the survival space due to the front wheels, front suspension, and other structures.

[0041] In this embodiment, a first reinforcing structure 3 extending along the height direction is provided on the top side of the threshold 2. Since the first reinforcing structure 3 connects the first folded wall 12 (specifically, the weak area of ​​the first folded wall 12 located on the top side of the threshold 2) and the top surface 2a of the threshold 2, it can guide the collision force at the weak area to be transmitted to the threshold 2, thereby helping to reduce the risk of tearing and instability in the weak area and improve the collision safety performance during frontal small overlap collisions.

[0042] In this embodiment, the specific range of the first reinforcing structure 3 extending along the height direction can be specifically determined by those skilled in the art based on the potential range of the collision force when a collision occurs, and there is no limitation thereto.

[0043] In some embodiments, refer to Figures 1-4 The first reinforcing structure 3 includes a first reinforcing wall 31. The top end of the first reinforcing wall 31 is connected to the first folding wall 12, and the bottom end is connected to the top surface 2a of the sill 2. Along the direction from the top end to the bottom end of the first reinforcing wall 31, the first reinforcing wall 31 extends obliquely away from the first folding wall 12. The oblique extension of the first reinforcing wall 31 in the above manner can improve the guiding effect of the first reinforcing structure 3 on the collision force, thereby further improving the collision safety performance in frontal small overlap collisions.

[0044] In this embodiment, the first reinforcing wall 31 can extend in a straight inclined shape, or in an arc or quasi-arc inclined shape, or in an S-shaped inclined shape, and there is no limitation on this.

[0045] In some embodiments, along the direction from the top to the bottom of the first reinforcing wall 31, the angle between the first reinforcing wall 31 and the first direction first increases and then decreases. Here, the angle between the first reinforcing wall 31 and the first direction specifically refers to the angle between one side surface of the first reinforcing wall 31 along its own thickness direction and the first direction. The one side surface of the first reinforcing wall 31 along its own thickness direction can be a plane or a curved surface. In the case that the one side surface of the first reinforcing wall 31 along its own thickness direction is a curved surface, the angle between the first reinforcing wall 31 and the first direction refers to the angle between the tangent of the curved surface and the first direction.

[0046] In this embodiment, this extension of the first reinforcing wall 31 helps to further improve the guiding effect of the first reinforcing structure 3 on the collision force, and also helps to optimize the stress distribution of the first reinforcing wall 31 itself, thereby improving the structural strength of the first reinforcing wall 31.

[0047] The top end of the first reinforcing wall 31 may form a first flange 31a for connection with the first folded wall 12. The connection method between the first flange 31a and the first folded wall 12 includes one or more of bolt connection, FDS connection, or welding. The bottom end of the first reinforcing wall 31 may form a second flange 31b for connection with the top surface 2a of the threshold 2. The connection method between the second flange 31b and the top surface 2a of the threshold 2 includes one or more of bolt connection, FDS connection, or welding.

[0048] In some embodiments, one end of the first reinforcing wall 31 along the second direction is connected to the body 11, thereby increasing its connection strength with the inner plate 1 of the support column. As an example, one or more third flanges 31c for connecting with the inner plate 1 of the support column may be formed at one end of the first reinforcing wall 31 along the second direction. The connection method between the third flanges 31c and the inner plate 1 of the support column includes one or more of bolt connection, FDS connection or welding.

[0049] In some embodiments, along the second direction, the dimensions of the first reinforcing wall 31 and the first folded wall 12 are approximately the same, thereby further enhancing the effective range of the first reinforcing wall 31.

[0050] In some embodiments, the first reinforcing structure 3 includes a second reinforcing wall 32, which is disposed opposite to the inner plate of the support column 1 along a second direction. In a projection plane perpendicular to the second direction, the projection of the first reinforcing wall 31 covers the area enclosed by the projections of the first reinforcing wall 31, the first folding wall 12, and the threshold 2.

[0051] It is understood that in the above embodiment, since the first reinforcing wall 31 extends at an angle, a triangular-like area may be formed between the first reinforcing wall 31, the threshold 2, and the first folding wall 12. The first folding wall 12 is relatively weak at the position corresponding to this area. Therefore, in this embodiment, a second reinforcing wall 32 is provided. In the projection plane perpendicular to the second direction, the projection of the second reinforcing wall 32 covers the above-mentioned area. In this way, the second reinforcing wall 32 can transfer the collision force of the first folding wall 12 at the position corresponding to the above-mentioned area to the threshold 2, thereby further reducing the risk of the first folding wall 12 tearing and becoming unstable, and improving the collision safety performance in frontal small overlap collisions.

[0052] In this embodiment, as an example, refer to Figure 3 and Figure 4 The second reinforcing wall 32 can be connected to the end of the first reinforcing wall 31 that is away from the body 11. The first reinforcing wall 31 and the second reinforcing wall 32 can be formed as a first type structure, or they can be connected by one or more of the following connection methods: bolt connection, FDS connection or welding.

[0053] One end of the second reinforcing wall 32 along the first direction can form a first connecting edge 32a. The first connecting edge 32a can be connected to the side end face of the first folded wall 12 facing away from the body 11. The connection method can include one or more of welding, bolt connection, and FDS connection.

[0054] The bottom end of the second reinforcing wall 32 may form a second connecting edge 32b for connecting with the threshold 2. The connection method between the second connecting edge 32b and the threshold 2 includes one or more of welding, bolting, and FDS connection.

[0055] In some embodiments, an inclined transition surface 2b is formed between the top surface 2a of the threshold 2 and the side surface of the threshold 2 facing away from the body 11, and the second connecting edge 32b can be formed as a flange and connected to the transition surface 2b. The transition surface 2b helps to provide support for the second reinforcing wall 32, thereby improving the positional stability of the first reinforcing structure 3.

[0056] In some embodiments, refer to Figure 4 The vehicle pillar and sill mounting assembly also includes a first connecting structure 4. The first connecting structure 4 includes a first connecting wall 41 and a second connecting wall 42 connected to each other. The first connecting wall 41 is connected to the side surface of the second reinforcing wall 32 facing the body 11, and the second connecting wall 42 is connected to the top surface 2a of the sill 2.

[0057] It is understood that in the embodiments described above, the connection between the first reinforcing wall 31 and the second reinforcing wall 32 and the threshold 2 is achieved by flanges or connecting edges. In order to meet the connection strength requirements, relatively complex processes may be required to improve the connection strength of the flanges or connecting edges. In this embodiment, a first connecting structure 4 is added. The first connecting structure 4 helps to improve the connection strength between the first reinforcing structure 3 and the threshold 2 while reducing the difficulty of production and assembly.

[0058] In this embodiment, as an example, the first connecting wall 41 can extend approximately along the height direction, and the second reinforcing wall 32 extends along the second direction. In the projection plane perpendicular to the first direction, the first reinforcing structure 3 is formed as an L-shaped structure.

[0059] The connection method between the first connecting wall 41 and the second reinforcing wall 32 may include one or more of welding, bolting, or FDS connection, and the connection method between the second connecting wall 42 and the top surface 2a of the threshold 2 may include one or more of welding, bolting, or FDS connection. The first connecting wall 41 and the second connecting wall 42 may be formed as an integral structure.

[0060] In some embodiments, the vehicle pillar and sill mounting assembly further includes a second connecting structure 5, which includes a third connecting wall 51 and a fourth connecting wall 52 connected to each other. The third connecting wall 51 connects the side surface of the first reinforcing wall 31 opposite to the first folding wall 12 and the top surface 2a of the sill 2, and the fourth connecting wall 52 connects the side surface of the second reinforcing wall 32 opposite to the body 11 and the sill 2.

[0061] Similar to the first reinforcing structure 3, the second reinforcing structure 6 also helps to improve the connection strength between the first reinforcing structure 3 and the sill 2 while reducing the difficulty of production and assembly. It should be noted that those skilled in the art can choose to provide only the first reinforcing structure 3, only the second reinforcing structure 6, or both the first reinforcing structure 3 and the second reinforcing structure 6, depending on actual needs.

[0062] The connection method between the third connecting wall 51 and the top surface 2a of the threshold 2 may include one or more of welding, bolting, or FDS connection. The connection method between the third connecting wall 51 and the first connecting wall 41 away from the first folding wall 12 may include one or more of welding, bolting, or FDS connection. Alternatively, the connection between the third connecting wall 51 and the first reinforcing wall 31 may be indirectly achieved through the connection between the fourth connecting wall 52 and the second reinforcing wall 32.

[0063] In the embodiment where the first reinforcing wall 31 extends at an angle, the third connecting wall 51 can be configured to follow the shape of the first reinforcing wall 31, that is, it also extends at an angle following the first reinforcing wall 31, thereby further improving the connection strength.

[0064] In the embodiment where the threshold 2 has a transition surface 2b, the bottom end of the fourth reinforcing wall can form a fourth flange 52a, which is connected to the transition surface 2b. In this case, the second connecting edge 32b can be located between the fourth flange 52a and the transition surface 2b.

[0065] The connection method between the fourth reinforcing wall and the second reinforcing wall 32 may include one or more of welding, bolting, or FDS connection, and the connection method between the fourth reinforcing wall and the threshold 2 may include one or more of welding, bolting, or FDS connection.

[0066] In some embodiments, refer to Figure 5 and Figure 6 The vehicle pillar and sill mounting assembly also includes a second reinforcing structure 6, which is disposed on the top side of the sill 2. The inner plate of the pillar 1 also includes a second folding wall 13 connected to the other side of the body 11 along the first direction. The second folding wall 13 is disposed opposite to the first folding wall 12. The second reinforcing structure 6 connects the first folding wall 12, the body 11 and the second folding wall 13.

[0067] In this embodiment, the first folding wall 12 and the second folding wall 13 can be used to connect with external structures including but not limited to the outer panel of the support column. The second reinforcing structure 6 connects the first folding wall 12, the body 11, and the second folding wall 13. Thus, the second reinforcing structure 6 can cooperate with the first reinforcing structure 3 to further enhance the structural strength of the first folding wall 12, thereby improving the collision safety performance in the event of a small frontal overlap collision.

[0068] The specific structural form of the second reinforcing structure 6 is not limited, as long as it can connect the first folding wall 12, the second folding wall 13 and the inner plate.

[0069] In some embodiments, the first reinforcing structure 3 and the inner plate 1 of the support column form a mounting cavity, and at least a portion of the second reinforcing structure 6 is located within the mounting cavity. This allows the supporting capacity of the first reinforcing structure 3 and the second reinforcing structure 6 to be superimposed, thereby achieving a better reinforcement effect.

[0070] As an example, the mounting cavity can be formed by the first reinforcing wall 31, the second reinforcing wall 32, the first folding wall 12, and the body 11 mentioned above. In this embodiment, at least a portion of the first reinforcing wall 31 along the height direction can be spaced apart from the inner plate to form an opening communicating with the mounting cavity, through which the second reinforcing structure 6 can extend out of the mounting cavity and connect with the second folding wall 13.

[0071] It should be noted that the setting method of the second strengthening structure 6 is not limited to this. In some other embodiments, the second strengthening structure 6 can also be staggered from the first strengthening structure 3 along the height direction of the pillar inner plate 1, or the second strengthening structure 6 can be arranged on the side of the first strengthening structure 3 away from the body 11.

[0072] In some embodiments, the second strengthening structure 6 forms a raised portion 6a, and a buffer cavity (not shown in the figure) is formed by enclosing between the raised portion 6a and the body 11. In this way, it helps to reduce the transmission of the collision force to the body 11 and the second folding wall 13.

[0073] In this embodiment, the specific structural form of the raised portion 6a is not limited. As an example, in the projection plane perpendicular to the first direction, the raised portion 6a can be in a U-shape, an arc shape, etc., and there is no limitation on this. Taking the raised portion 6a in a U-shape as an example, the opposite ends of the raised portion 6a along the first direction can form a fifth flanging 6b and a sixth flanging 6c. The fifth flanging 6b is welded to the first folding wall 12, and the sixth flanging 6c is welded to the second folding wall 13. At least one end of the raised portion 6a along the height direction forms a seventh flanging 6d, and the seventh flanging 6d is welded to the body 11.

[0074] In some embodiments, referring to Figure 2 , the first strengthening structure 3避让 the second folding wall 13. The first strengthening structure 3避让 the second folding wall 13 specifically means that the first strengthening structure 3 does not come into contact with the second folding wall 13. Specifically, along the first direction, the distance between any point on the first strengthening structure 3 and the second folding wall 13 is not less than 3 - 10 mm, such as not less than 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0075] As mentioned above, the second folding wall 13 is used for welding with related structures, such as the pillar outer plate, the second strengthening structure 6, etc. In this embodiment, the first strengthening structure 3避让 the second folding wall 13, which helps to a certain extent prevent the collision force from being transmitted to the second flanging 31b (the collision force basically cannot be transmitted to the second folding wall 13 through the first strengthening structure 3). In this way, the risk of cracking of the solder joints and / or weld seams on the second folding wall 13 during a collision can be reduced.

[0076] The embodiments of the present application further include a vehicle, and the vehicle includes the installation assembly of the vehicle pillar and the sill as described in any one of the above embodiments.

[0077] The vehicle of the embodiments of the present application has all the advantages of the installation assembly of the vehicle pillar and the sill as described in any one of the above embodiments, and will not be elaborated here.
