The reinforcing component is connected to the inner panel of the A-pillar, thereby improving the support and force transmission effect on the inner panel of the A-pillar. The embodiments of this application also provide an A-pillar assembly having the above-mentioned reinforcing component and a vehicle having such an A-pillar assembly. The embodiments of this application are introduced below in combination with the drawings in the specification:

[0046] ReferenceFigure 1 and Figure 2 The A-pillar assembly of the embodiment of the present application includes an A-pillar inner panel 300 and a reinforcement component. The A-pillar inner panel 300 has a cavity 310. The reinforcement component is arranged in the cavity 310. The reinforcement component is connected to the A-pillar inner panel 300 for locally enhancing the strength of the A-pillar inner panel 300 and improving the deformation resistance of the A-pillar.

[0047] refer to Figures 3 to 6 The reinforcement component of the embodiment of the present application includes a first bracket 100 and a second bracket 200. The combination of the first bracket 100 and the second bracket 200 can improve the overall rigidity and strength, increase the support for the A-pillar inner panel 300 in the Z direction and the X direction, and improve the anti-deformation ability of the A-pillar assembly, which is beneficial to reduce the intrusion of the passenger compartment during a collision and improve safety.

[0048] In the reinforcement assembly of some embodiments, the first bracket 100 includes a body 110 and walls 120 relatively arranged at both ends of the body 110 along the Z direction, the walls 120 are connected to the body 110 and extend along the Y direction, and the Y direction is perpendicular to the Z direction. Therefore, from the perspective along the Y direction, the body 110 of the first bracket 100 and the two walls 120 form an "I"-shaped structure with strong rigidity, stable force and continuity. The body 110 of the first bracket 100 and the two walls 120 together form a receiving cavity, so that the cross section of the first bracket 100 along the Y direction forms a "J"-shaped structure. After the first bracket 100 is connected to the A-pillar inner panel 300, the body 110, the side wall 312 and the A-pillar inner panel 300 can be surrounded to form a relatively closed cavity structure. The end of the wall body 120 away from the main body 110 along the Y direction is used to connect to the A-pillar inner panel 300, which can provide Y-direction support for the A-pillar inner panel 300. The main body 110 is supported between the two walls 120 along the Z direction. The two ends of the wall body 120 along the X direction are used to connect to the A-pillar inner panel 300. The X direction is perpendicular to the Y direction and the Z direction. Therefore, the wall body 120 can provide X-direction support for the A-pillar inner panel 300.

[0049] When a collision occurs, the A-pillar inner panel 300 undergoes stress deformation and transmits the collision force to the first bracket 100. The first bracket 100 provides support in the Z, Y and X directions to resist deformation in multiple directions, thereby reducing the deformation of the cavity 310 of the A-pillar inner panel 300, which is beneficial to reducing the intrusion into the crew cabin and improving safety.

[0050] The reinforcement assembly of the embodiment of the present application further includes a second bracket 200 , and the second bracket 200 includes a support portion 210 .

[0051] The support portion 210 is located between the walls 120, and the two ends of the support portion 210 along the Z direction are respectively connected to the corresponding walls 120, so that the second bracket 200 can increase the support of the wall 120 in the Z direction through the support portion 210, and can effectively suppress the rebound while improving the rigidity and strength of the first bracket 100. Therefore, the combination of the second bracket 200 and the first bracket 100 improves the rigidity and strength of the entire reinforcement component and improves the anti-deformation ability.

[0052] In some embodiments, the second bracket 200 may also include a first connecting portion 220 and a second connecting portion 230, the first connecting portion 220 and the second connecting portion 230 are respectively connected to the two ends of the support portion 210 along the Y direction, the first connecting portion 220 is connected to the main body 110, and the second connecting portion 230 is used to connect the A-pillar inner panel 300, and can increase the support for the A-pillar inner panel 300 in the Y direction, thereby transmitting force to the main body 110 of the first bracket 100, further improving the overall stiffness, strength and anti-deformation ability of the reinforcement component.

[0053] In the A-pillar assembly of some embodiments, the wall surface of the cavity 310 of the A-pillar inner panel 300 includes a bottom wall 311 and side walls 312 disposed on both sides of the bottom wall 311 along the X direction.

The two walls 120 of the first bracket 100 are connected to the A-pillar inner panel 300 at intervals in the Z direction. One end of each wall 120 away from the body 110 in the Y direction is connected to the bottom wall 311 in the Y direction of the cavity 310 of the A-pillar inner panel 300. Both ends of each wall 120 in the X direction are respectively connected to the side walls 312 in the X direction of the cavity 310 of the corresponding A-pillar inner panel 300. The wall 120 realizes the X-direction support of the A-pillar inner panel 300, and the body 110 supports the two wall bodies 120 in the Z direction. The second bracket 200 can effectively utilize the accommodation cavity between the body 110 of the first bracket 100 and the two wall bodies 120, and is connected to the first bracket 100 and the A-pillar inner panel 300, which is conducive to improving the transmission of force during collision and reducing stress concentration.

[0056] The supporting portion 210 of the second bracket 200 is supported between the two walls 120 along the Z direction, and is supported between the Y-direction bottom wall 311 of the A-pillar inner panel 300 and the main body 110 of the first bracket 100 along the Y direction, thereby increasing the support of the reinforcing component along the Z direction and the Y direction, thereby improving the support and force transmission effect of the A-pillar inner panel 300, effectively improving the rigidity and strength of the reinforcing component, and further improving the deformation resistance of the A-pillar, which is beneficial to reducing the intrusion of the passenger compartment during a collision and improving safety.

[0059] The second connection portion 230 is extended in the X direction relative to the support portion 210, and has a second connection surface 231 on the side of the second connection portion 230 that is away from the main body 110.

The second long hole 212 can absorb part of the error or deviation, which is convenient for penetrating the positioning pin.

[0076] As an example, the first bracket 100 may be a structure integrally formed of a plate, the body 110 may be a plate-like structure extending along the Z direction and the X direction, the wall 120 may be a plate-like structure extending along the Y direction and the X direction by bending in the Y direction relative to the body 110, and the first mounting portion 130 and the second mounting portion 140 in some of the above embodiments may be a flanged structure bent in the Z direction relative to the wall 120. Alternatively, the first mounting portion 130, the second mounting portion 140, the body 110, and the wall 120 may be plates respectively, connected into one by a fixed connection.

[0077] It can be understood that in the description of the embodiments of the present application, some structures are described as extending or bending along a specified direction (for example, the X direction, the Y direction, or the Z direction) or toward a specified direction, which is not limited to the structure being parallel to the specified direction, but rather indicates the direction of extension or bending relative to other structures. The structure can be parallel to the specified direction or have an angle greater than 0.

[0078] In the embodiment of the present application, the reinforcement component reasonably utilizes the limited space provided by the cavity 310 of the A-pillar inner panel 300. Through the combination of the first bracket 100 and the second bracket 200, the rigidity and strength can be effectively improved without increasing the thickness of the material, thereby improving the anti-deformation ability of the A-pillar assembly and achieving the safety requirements. Some embodiments further provide a weight-reducing structure to effectively reduce the weight of parts and achieve lightweight requirements. In addition, some embodiments improve the stability of the connection by providing a connection part (such as the first connection part 220, the second connection part 230 or the third connection) and its connection surface, or providing a mounting part (such as the first mounting part 130 or the second mounting part 140) and its mounting surface. By reasonably arranging the welding points, abnormal noise can be effectively suppressed and NVH performance can be optimized.

[0079] refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 8 In some embodiments of the A-pillar assembly, the bottom wall 311 of the cavity 310 of the A-pillar inner panel 300 may be provided with a first boss 313 and / or a second boss 314. The first boss 313 is provided to protrude along the Y direction corresponding to the positions L1 and L2 of the two walls 120 of the first bracket 100, and the end of the wall 120 of the first bracket 100 that is away from the body 110 along the Y direction is connected to the first boss 313. The second boss 314 is provided to protrude along the Y direction corresponding to the position L3 of the support portion 210 of the second bracket 200, and the support portion 210 is connected to the second boss 314. For example, in the solution in which the second bracket 200 is provided with the second connecting portion 230, the position of the second boss 314 corresponds to the second connecting portion 230, and the support portion 210 is connected to the second boss 314 through the second connecting portion 230.

[0080] Therefore, for the inner A-pillar panel 300 of different vehicle models or with different cavity 310 structures, the height of the first boss and / or the second boss protruding in the Y direction can be adjusted. Or, in some embodiments, according to the actual installation requirements, the first boss 313 and the second boss 314 described above may not be provided on the bottom wall 311. Refer to Figure 7 , the bottom wall 311 can be formed into a flat planar structure. The wall body 120 of the first bracket 100 and the second connecting portion 230 of the second bracket 200 can be directly connected to the bottom wall 311 to achieve the adaptation of the reinforcement assembly, which can meet the common use of multiple vehicle models, ensure the consistency of the reinforcement assembly structure, and improve the generalization rate. Thus, it is beneficial to meet the development requirements of multiple vehicle models with the same safety collision strategy and different body shapes based on the architecture platform development, thereby shortening the development cycle and reducing the development cost.

[0081] The embodiment of the present application also provides a vehicle, including the A-pillar assembly of the above embodiment. Through the inner A-pillar panel 300 and the reinforcement assembly of the A-pillar assembly, the intrusion amount of the occupant compartment can be effectively reduced, the lives of the occupants can be protected, and the vehicle safety can be improved.

[0082] The vehicle involved in the embodiment of the present application can be a private car, such as a sedan, an SUV, an MPV or a pickup truck, etc. The vehicle can also be an operating vehicle, such as a minibus, a bus, a small truck or a large trailer, etc. The vehicle can be an oil vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0083] The above has described the embodiments of the present application in detail with reference to the drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
