[0033] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0034] Reference will be made below Figures 1-8 to describe the column structure 100 according to the embodiment of the first aspect of the present utility model.

[0035] As Figures 1-5 shown, the column structure 100 according to the embodiment of the first aspect of the present utility model includes: a column outer plate 10, a column inner plate 20, and a column reinforcement 30.

[0036] The column outer plate 10 is arranged on the side of the column inner plate 20 facing away from the passenger compartment; the column reinforcement 30 is disposed between the column outer plate 10 and the column inner plate 20 and is fixedly connected to the column outer plate 10 and the column inner plate 20 respectively; the column reinforcement 30 includes a reinforcement column body 32, the reinforcement column body 32 is a hollow column extending vertically, and a cavity 31 is defined inside the reinforcement column body 32, and the wall thickness of the front side wall of the cavity 31 is greater than the wall thickness of the remaining side walls of the cavity 31.

[0037] It should be noted that the column structure of the present application is the A-pillar structure of a vehicle. The A-pillar structure of a vehicle refers to the front pillars on both sides of the windshield of the vehicle. The A-pillar structure of the vehicle connects the roof and the front apron and plays a key role in the overall structural strength and vehicle safety of the vehicle.

[0038] For example Figures 1-3 as shown, the column outer plate 10 is arranged on the left side of the column inner plate 20, the column reinforcement 30 is disposed between the column outer plate 10 and the column inner plate 20, and a fixed connection is adopted between the column reinforcement 30 and the column outer plate 10, and a fixed connection is adopted between the column reinforcement 30 and the column inner plate 20.

[0039] For example Figure 4 and Figure 5As shown, in the vertical direction of the vehicle, the reinforcing column 32 extends along the vertical direction. There is a cavity 31 inside the reinforcing column 32. Further, the cross-section of the reinforcing column 32 can adopt a thin-walled box-shaped cross-section, which has excellent bending and torsional resistance performance, can make full use of the material characteristics, and save the material consumption. The wall thickness of the front side wall of the cavity 31 is greater than the wall thicknesses of the left side wall, the right side wall, and the rear side wall of the cavity 31, so as to additionally increase the strength and stiffness of the front side wall, so that the front side wall can absorb more energy during a collision, and further help to disperse the impact force, further ensuring the safety of passengers. In the front-rear direction of the vehicle, the front side wall of the cavity 31 is located in front of the rear side wall.

[0040] In this embodiment, when an offset collision occurs, the reinforcing column 32 extending along the vertical direction of the column reinforcement 30 deforms under the action of the collision force, and the reinforcing column 32 can effectively absorb the energy generated by the collision force through its own deformation. At the same time, the reinforcing column 32 extending along the vertical direction can transmit the collision force in the vertical direction to other areas, so as to effectively reduce the damage to the fixed connection between the outer column panel 10 and the inner column panel 20 caused by the collision force. Thus, the overall rigidity and stability of the column structure 100 can be effectively improved, the column can be prevented from tearing, and the integrity of the vehicle occupant compartment and the safety of vehicle occupants can be ensured. In addition, the self-weight can be effectively reduced, the material utilization rate can be improved, and the material cost can be effectively reduced.

[0041] In addition, through the fixed connection between the column reinforcement 30 and the outer column panel 10 and the inner column panel 20, the collision force can be effectively transmitted from the column reinforcement 30 to the outer column panel 10 and the inner column panel 20. Under the action of the collision force, the outer column panel 10 and the inner column panel 20 deform and absorb the energy generated by the collision force. Thus, the collision force can be effectively transmitted and dispersed.

[0042] The collision force can also be effectively transmitted from the outer column panel 10 and the inner column panel 20 to other areas, so that the collision force can be further transmitted and dispersed, thereby effectively avoiding concentrated damage caused by the collision and further protecting the vehicle and the occupants. Preferably, the column reinforcement 30 can be made of aluminum alloy, and the aluminum alloy has the advantages of light weight and easy processing. Thus, the weight of the column reinforcement 30 can be effectively reduced, the processing of the column reinforcement 30 is convenient, the working hours are saved, and the cost is reduced.

[0043] According to the column structure 100 of the embodiment of the present utility model, by providing a column outer plate, a column inner plate, and a column reinforcing member located between the column outer plate and the column inner plate, and arranging a hollow columnar reinforcing column body extending vertically in the column reinforcing member, a cavity is defined inside the reinforcing column body, and the wall thickness of the front side wall of the cavity is greater than the wall thicknesses of the other side walls of the cavity, which can effectively resist the collision force, prevent the column from tearing, thereby effectively improving the anti-offset collision ability, and further effectively ensuring the integrity of the vehicle occupant compartment and the safety of vehicle occupants. In addition, the column structure 100 can effectively reduce the weight, lower the processing difficulty, save the manufacturing man-hours, and save costs.

[0044] For example, the column outer plate 10 and the column inner plate 20 are fixedly connected. Further, the fixed connection manner between the column outer plate 10 and the column inner plate 20 can adopt spot welding. For example, the connection manner between the column reinforcing member 30 and the column outer plate 10 can adopt flow drill screw connection, and the connection manner between the column reinforcing member 30 and the column inner plate 20 can adopt flow drill screw connection.

[0045] It should be noted that spot welding, also known as resistance spot welding, is a commonly used metal welding technique and can be used for connecting thin sheet metals. The basic principle of spot welding is to utilize the resistance heat generated by the current passing through the contact points of two metal parts to be welded to melt the metal, thereby forming a weld point. This process is usually completed instantaneously, with high efficiency and simple operation.

[0046] It should be noted that flow drill screw connection is a mechanical connection process that uses the heat generated by the high-speed rotation of the screw to melt the base material, increases the pressure to penetrate the base material and makes threads on the base material, so as to fix two or more layers of sheet materials together. This kind of screw can form threads on the base material during the installation process, without the need for pre-drilling or tapping, which simplifies the assembly process and improves the production efficiency.

[0047] It should be noted that aluminum alloy is an alloy material based on aluminum and added with one or more alloying elements. By adding different alloying elements, the mechanical properties of aluminum can be significantly improved, such as increasing strength, hardness, and wear resistance, while maintaining its advantages of light weight and corrosion resistance. Generally speaking, aluminum alloy has the advantages of high specific strength, light weight, low cost, easy processing, corrosion resistance, and recyclability.

[0048] Preferably, the column reinforcing member 30 can be manufactured by using the aluminum alloy material extrusion molding process. The aluminum alloy material extrusion molding process is a processing technology that extrudes a metal blank with a solid or hollow cross-sectional shape through a mold under high temperature and high pressure conditions, and has the advantages of simple process flow, high production capacity, and low mold cost. The column reinforcing member 30 manufactured by using the extrusion molding process has excellent bending resistance and anti-collision performance.

[0049] In an embodiment of the present utility model, such asFigure 4 and Figure 5 As shown in Figure 5 , the wall thickness H1 of the front side wall of the cavity 31 is greater than or equal to 4 mm. For example, the cavity 31 formed by the reinforcing column 32 may have four side walls, namely the front side wall, the rear side wall, the left side wall and the right side wall. Further, the joints between the side walls may be connected by arc transitions, and the left side wall and the right side wall of the cavity 31 may be arranged in parallel. The wall thickness H1 of the front side wall of the cavity 31 is greater than or equal to 4 mm. For example, the wall thickness H1 of the front side wall of the cavity 31 may be 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm and 5 mm.

[0050] The wall thickness H2 of the left side wall of the cavity 31 is greater than or equal to 2.5 mm and less than or equal to 3 mm. For example, the wall thickness H2 of the left side wall of the cavity 31 may be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm and 3 mm. The wall thickness H3 of the right side wall of the cavity 31 is greater than or equal to 2.5 mm and less than or equal to 3 mm. For example, the wall thickness H3 of the right side wall of the cavity 31 may be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm and 3 mm.

[0051] When a collision occurs, the front side wall of the cavity 31 first deforms under the action of the collision force. The front side wall of the cavity 31 has sufficient thickness to absorb the energy generated by the collision force through deformation. At the same time, the front side wall of the cavity 31 can transmit the collision force to the left side wall, the right side wall and the rear side wall of the cavity 31, and the left side wall, the right side wall and the rear side wall of the cavity 31 absorb the energy generated by the collision force through deformation.

[0052] In this embodiment, by setting the wall thickness H1 of the front side wall of the cavity 31 to be greater than or equal to 4 mm, it can be ensured that the front side wall of the cavity 31 has sufficient thickness, thereby effectively improving the strength and stiffness of the reinforcing column 32, and further avoiding the tearing of the column structure 100. In addition, it can also ensure that the reinforcing column 32 made of aluminum alloy exhibits good plastic deformation ability during collision, avoiding brittle fracture, so that the collision force can be effectively transmitted and dispersed within the reinforcing column 32.

[0053] In an embodiment of the present utility model, as Figure 4 and Figure 5 shown, the column reinforcing member 30 further includes a reinforcing rib 33. The reinforcing rib 33 is disposed in the cavity 31, the reinforcing rib 33 extends vertically, and both ends in the width direction of the reinforcing rib 33 are connected to the opposite side walls of the cavity 31 respectively.

[0054] When a collision occurs, the reinforcing column 32 deforms under the action of the collision force and effectively transmits the collision force to the reinforcing rib 33. The reinforcing rib 33 absorbs the energy generated by the collision force through deformation under the action of the collision force, so as to disperse the collision force borne by the reinforcing column 32 and avoid premature failure of the local structure of the reinforcing column 32 during the collision.

[0055] In this embodiment, by arranging the reinforcing rib 33 in the column reinforcing member 30, the lateral support inside the cavity 31 can be increased, thereby effectively improving the bending and torsional resistance of the column reinforcing member 30, optimizing the absorption of the energy generated by the collision force, and further effectively improving the structural stability. In addition, the arrangement form of the reinforcing rib 33 can be flexibly adjusted according to requirements, so as to meet different design requirements, and further effectively expand the application range of the column reinforcing member 30.

[0056] In an embodiment of the present utility model, as Figure 4 and Figure 5 shown, the reinforcing rib 33 includes a first rib 331. The first rib 331 extends along the front and rear of the vehicle, and the front and rear ends of the first rib 331 are respectively connected to the front side wall and the rear side wall of the cavity 31. For example, the first rib 331 is arranged inside the cavity 31, the front end of the first rib 331 is connected to the front side wall of the cavity 31, and the rear end of the first rib 331 is connected to the rear side wall of the cavity 31. Further, the first rib 331 can be arranged parallel to the left side wall and the right side wall of the cavity 31, and the thickness H4 of the first rib 331 is greater than or equal to 2.5 mm and less than or equal to 3 mm. For example, the thickness H4 of the first rib 331 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, and 3 mm.

[0057] When a collision occurs, the front side wall of the cavity 31 can transmit the collision force to the first rib 331. The first rib 331 deforms under the action of the collision force, and the first rib 331 absorbs the energy generated by the collision force through deformation. In addition, the collision force can be transmitted from the front end of the first rib 331 to the rear end of the first rib 331, and then transmitted to the rear side wall of the cavity 31. The rear side wall of the cavity 31 can absorb the energy generated by the collision force through deformation.

[0058] Thus, by arranging the first rib 331 inside the cavity 31 and connecting the front and rear ends of the first rib 331 to the front side wall and the rear side wall of the cavity 31 respectively, additional support can be provided for the front side wall of the cavity 31 in the front-rear direction, so that the structural shape of the front side wall of the cavity 31 can be effectively maintained during the collision, avoiding excessive deformation of the front side wall of the cavity 31, and further effectively improving the structural rigidity of the column reinforcing member 30. In addition, the first rib 331 can also effectively transmit the collision force from the front side wall of the cavity 31 to the rear side wall of the cavity 31, so as to realize the effective transmission and dispersion of the collision force.

[0059] In an embodiment of the present utility model, as shown in Figure 4 and Figure 5 shown, both side surfaces of the first rib 331 in the thickness direction are arc-connected to the front side wall surface of the cavity 31, and the arc radius at the connection position of the first rib 331 and the front side wall surface of the cavity 31 is greater than or equal to 15 mm.

[0060] For example, the left side surface of the first rib 331 and the front side wall of the cavity 31 are connected by an arc transition, and the radius R1 of the arc is greater than or equal to 15 mm. For example, the radius R1 of the arc can be 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm. For example, the right side surface of the first rib 331 and the front side wall of the cavity 31 are connected by an arc transition, and the radius R2 of the arc is greater than or equal to 15 mm. For example, the radius R2 of the arc can be 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm. Further, both side surfaces of the first rib 331 in the thickness direction can also be connected to the rear side wall surface of the cavity 31 by an arc transition.

[0061] During a collision, stress concentration is likely to occur at the right-angle or acute-angle joints of the structure. Stress concentration will reduce the fatigue life of the material and increase the brittleness of the structure. The connection position between the first rib 331 and the front side wall surface of the cavity 31 is connected by an arc transition, which can effectively relieve the stress concentration phenomenon. Further, the arc radius at the connection position of the first rib 331 and the front side wall surface of the cavity 31 is greater than or equal to 15 mm, which can increase the contact area between the first rib 331 and the front side wall of the cavity 31, make the stress distribution more uniform, reduce the local stress peak value, and avoid the damage at the connection position between the first rib 331 and the front side wall of the cavity 31.

[0062] In this embodiment, by setting both side surfaces of the first rib 331 in the thickness direction to be arc-connected to the front side wall surface of the cavity 31 and the arc radius to be greater than or equal to 15 mm, the stress distribution at the connection position between the first rib 331 and the front side wall of the cavity 31 during a collision can be made more uniform, thereby effectively improving the durability and safety of the connection position between the first rib 331 and the front side wall of the cavity 31, and further effectively increasing the fatigue life of the column reinforcement 30.

[0063] In an embodiment of the present utility model, as shown in Figure 4 and Figure 5As shown in the figure, the reinforcing rib 33 further includes a second rib 332. The second rib 332 extends along the left - right direction of the vehicle, and the left and right ends of the second rib 332 are respectively connected to the left side wall and the right side wall of the cavity 31. For example, the second rib 332 is arranged inside the cavity 31. The left end of the second rib 332 is connected to the left side wall of the cavity 31, and the right end of the second rib 332 is connected to the right side wall of the cavity 31. Further, the two side surfaces of the left end of the second rib 332 in the thickness direction can be connected to the left side wall surface of the cavity 31 by arc transition, and the two side surfaces of the right end of the second rib 332 in the thickness direction can be connected to the right side wall surface of the cavity 31 by arc transition.

[0064] Further, the second rib 332 can be vertically arranged on the first rib 331. The corners at the connection of the second rib 332 and the first rib 331 can be connected by arc transition. The thickness H5 of the second rib 332 is greater than or equal to 2.5 mm and less than or equal to 3 mm. For example, the thickness H5 of the second rib 332 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, and 3 mm. When a collision occurs, the left side wall and the right side wall of the cavity 31 can transmit the collision force to the second rib 332. The second rib 332 deforms under the action of the collision force, and the second rib 332 absorbs the energy generated by the collision force through deformation. Thus, the second rib 332 can jointly resist and disperse external forces from different directions with the first rib 331.

[0065] Thus, by arranging the second rib 332 inside the cavity 31 and connecting the left and right ends of the second rib 332 to the left side wall and the right side wall of the cavity 31 respectively, additional support can be provided for the left side wall and the right side wall of the cavity 31 in the left - right direction, so that the structural shapes of the left side wall and the right side wall of the cavity 31 can be effectively maintained during a collision, avoiding excessive deformation of the left side wall and the right side wall of the cavity 31, thereby further improving the structural rigidity of the column reinforcement 30, and then effectively ensuring the structural integrity and reliability of the column reinforcement 30 under complex load conditions.

[0066] In an embodiment of the present invention, as Figures 1-3 shown, the outer column panel 10 includes: an upper outer panel 11 and a lower outer connecting panel 12. The upper outer panel 11 is arranged above the lower outer connecting panel 12 and is lap - connected to the lower outer connecting panel 12; the inner column panel 20 includes: an upper inner panel 21 and a lower inner connecting panel 22. The upper inner panel 21 is arranged above the lower inner connecting panel 22 and is lap - connected to the lower inner connecting panel 22. The column reinforcement 30 is arranged between the lower inner connecting panel 22 and the lower outer connecting panel 12 and is fixedly connected to the lower inner connecting panel 22 and the lower outer connecting panel 12, and the upper end of the column reinforcement 30 is lap - connected to the upper outer panel 11 and the upper inner panel 21.

[0067] For example, spot welding can be used for the connection between the upper outer panel 11 and the lower outer connecting plate 12, and spot welding can also be used for the connection between the upper inner panel 21 and the lower inner connecting plate 22. Further, spot welding can be used for the connection between the upper outer panel 11 and the upper inner panel 21, and the upper outer panel 11 and the upper inner panel 21 can jointly form a structure with a cavity. Spot welding can be used for the connection between the lower outer connecting plate 12 and the lower inner connecting plate 22. The upper outer panel 11, the upper inner panel 21, the lower outer connecting plate 12, and the lower inner connecting plate 22 can be made of ultra-high strength or hot-formed steel to ensure the strength and stiffness of the structural body.

[0068] For example, flow drill screws can be used for the connection between the column reinforcement 30 and the lower outer connecting plate 12, and flow drill screws can also be used for the connection between the column reinforcement 30 and the lower inner connecting plate 22. For example, flow drill screws can be used for the connection between the upper end of the column reinforcement 30 and the upper outer panel 11, and flow drill screws can also be used for the connection between the upper end of the column reinforcement 30 and the upper inner panel 21.

[0069] During a collision, the column reinforcement 30 is first deformed by the collision force. The column reinforcement 30 absorbs the energy generated by the collision through deformation and effectively transfers the collision force to the upper outer panel 11, the upper inner panel 21, the lower outer connecting plate 12, and the lower inner connecting plate 22. The upper outer panel 11 and the upper inner panel 21 absorb the energy generated by the collision force through deformation and effectively transfer the collision force to other areas. The lower outer connecting plate 12 and the lower inner connecting plate 22 absorb the energy generated by the collision force through deformation and effectively transfer the collision force to other areas.

[0070] In this embodiment, by fixedly connecting the column reinforcement 30 to the lower inner connecting plate 22 and the lower outer connecting plate 12, and lap-connecting the column reinforcement 30 to the upper outer panel 11 and the upper inner panel 21, the collision force can be effectively transferred from the column reinforcement 30 to the upper outer panel 11, the upper inner panel 21, the lower outer connecting plate 12, and the lower inner connecting plate 22, and finally effectively transferred to other areas, thereby effectively dispersing the collision force and further effectively reducing the harm of the collision force to the vehicle and the occupants.

[0071] In an embodiment of the present utility model, as Figures 1-3 and Figure 8 shown, the column structure 100 further includes a sill 40. The sill 40 extends front and back and is arranged below the column reinforcement 30. The lower ends of the lower inner connecting plate 22 and the lower outer connecting plate 12 respectively extend to both sides of the sill 40 and are fixedly connected to the sill 40.

[0072] For example, the threshold 40 is made of aluminum alloy. The threshold 40 extends forward and backward, and the front end of the threshold 40 is arranged on the lower side of the lower end of the column reinforcement 30. Further, the lower end of the lower inner connecting plate 22 extends to the right side of the front end of the threshold 40 and is connected by a flow drill screw. The lower end of the lower outer connecting plate 12 extends to the left side of the front end of the threshold 40 and is connected by a flow drill screw. Further, the threshold 40 is a beam structure with a cavity, and a transverse support member 41 can be provided in the cavity.

[0073] During a collision, the collision force is effectively transmitted from the lower outer connecting plate 12 and the lower inner connecting plate 22 to the front end of the threshold 40. The threshold 40 can absorb the energy generated by the collision force through deformation and effectively transmit the collision force from the front end of the threshold 40 to the rear end of the threshold 40, and finally effectively transmit it to other areas.

[0074] In this embodiment, by providing the threshold 40 in the column structure 100, the collision force can be further transmitted and dispersed, thereby further increasing the safety of the column structure 100 and further improving the protection of the vehicle and its occupants. In addition, the threshold 40 made of aluminum alloy can further reduce the weight of the column structure 100.

[0075] In an embodiment of the present utility model, as Figures 1-3 shown, in the direction from top to bottom, at least a part of the rear side edge of the lower inner connecting plate 22 or the rear side edge of the lower outer connecting plate 12 extends backward obliquely and extends to be connected to the upper surface of the threshold 40.

[0076] For example, both the rear side edge of the lower inner connecting plate 22 and the rear side edge of the lower outer connecting plate 12 extend backward obliquely in part and extend to be connected to the upper surface of the threshold 40.

[0077] For example, both the rear side edge of the lower inner connecting plate 22 and the rear side edge of the lower outer connecting plate 12 extend backward obliquely entirely and extend to be connected to the upper surface of the threshold 40.

[0078] In this embodiment, by extending at least a part of the rear side edge of the lower inner connecting plate 22 or the rear side edge of the lower outer connecting plate 12 backward obliquely and extending to be connected to the upper surface of the threshold 40, a triangular structure can be formed at the connection between the lower inner connecting plate 22 and the lower outer connecting plate 12 and the threshold 40, thereby effectively ensuring the structural strength and stability of the connection, and further effectively ensuring the transmission of the collision force.

[0079] In an example, in the direction from top to bottom, at least a part of the lower inner connecting plate 22 gradually increases in width in the front-rear direction. For example, in the direction from top to bottom, a part of the lower inner connecting plate 22 gradually increases in width in the front-rear direction. Another example is that in the direction from top to bottom, the entire lower inner connecting plate 22 gradually increases in width in the front-rear direction.

[0080] In this embodiment, by setting the width of at least part of the lower inner connecting plate 22 in the front - rear direction to gradually increase from top to bottom, the connection area between the lower inner connecting plate 22 and the sill 40 can be effectively increased, thereby effectively dispersing stress and avoiding stress concentration. In addition, materials can be effectively saved and costs can be reduced.

[0081] In one example, in the direction from top to bottom, the width of at least part of the lower outer connecting plate 12 in the front - rear direction gradually increases. For example, in the direction from top to bottom, the width of a part of the lower outer connecting plate 12 in the front - rear direction gradually increases. Another example is that in the direction from top to bottom, the width of the entire lower outer connecting plate 12 in the front - rear direction gradually increases.

[0082] In this embodiment, by setting the width of at least part of the lower outer connecting plate 12 in the front - rear direction to gradually increase from top to bottom, the connection area between the lower outer connecting plate 12 and the sill 40 can be effectively increased, thereby effectively dispersing stress and avoiding stress concentration. In addition, materials can be effectively saved and costs can be reduced.

[0083] As Figures 1-8 shown, the vehicle according to the second - aspect embodiment of the present utility model includes the column structure 100 according to the first - aspect embodiment of the present utility model above. For example, two column structures 100 are provided in the vehicle, one column structure 100 is arranged at the left front of the driver's seat, and the other column structure 100 is arranged at the right front of the passenger seat. Further, two B - pillar mechanisms are also provided in the vehicle, one B - pillar structure is arranged at the left rear of the driver's seat, and the other B - pillar structure is arranged at the right rear of the passenger seat.

[0084] When a offset collision occurs, the strengthening column body 32 of the column reinforcement 30 deforms under the action of the collision force. The strengthening column body 32 can effectively absorb the energy generated by the collision force through its own deformation. Thus, the column can be prevented from being torn, ensuring the integrity of the vehicle occupant compartment and the safety of vehicle occupants.

[0085] In addition, through the fixed connection between the column reinforcement 30 and the column outer panel 10 and the column inner panel 20, the collision force can be effectively transmitted from the column reinforcement 30 to the column outer panel 10 and the column inner panel 20. Under the action of the collision force, the column outer panel 10 and the column inner panel 20 deform and absorb the energy generated by the collision force. Thus, the collision force can be effectively transmitted and dispersed.

[0086] The impact force can also be effectively transmitted to the B-pillar structure through the outer pillar panel 10 and the inner pillar panel 20, and the B-pillar structure can absorb the energy generated by the impact force through deformation. Thus, the impact force can be further transmitted and dispersed, effectively avoiding concentrated damage caused by the collision, and further protecting the vehicle and the occupants. In addition, the pillar reinforcement 30 is made of aluminum alloy, which can effectively reduce the weight of the pillar reinforcement 30, facilitate the processing of the pillar reinforcement 30, save working hours, and reduce costs.

[0087] For the vehicle according to the embodiment of the present invention, by providing the pillar structure 100 of the above-mentioned first aspect embodiment, the impact force can be effectively resisted, the tearing of the pillar can be prevented, thereby effectively improving the offset collision resistance ability, and further effectively ensuring the integrity of the vehicle occupant compartment and the safety of the vehicle occupants. In addition, the pillar structure 100 can effectively reduce the weight, reduce the processing difficulty, save the manufacturing working hours, and save costs.
