[0029] The vehicle limiter is one of the important components of the vehicle. It is used to limit the opening of the door and prevent damage to the door. In order to strengthen the connection strength between the limiter and the vehicle pillar, a limiter reinforcement plate is usually set inside the vehicle pillar to increase the connection strength and vehicle pillar stiffness.

[0030] The traditional limiter reinforcement plate and the vehicle pillar have poor assembly accuracy and insufficient connection strength when connected, making it difficult to assemble the limiter reinforcement plate and the vehicle pillar. Therefore, the limiter reinforcement plate structure needs to be improved.

[0031] In order to solve the related technical problems, the present application provides a vehicle pillar, see Figure 1 , Figure 1 It is a structural schematic diagram of the vehicle pillar provided by this application.

[0032] The vehicle pillar 1 includes a pillar body 10 and a limiter reinforcement 20. The vehicle pillar 1 forms an energy absorbing cavity 110. The limiter reinforcement 20 is located in the energy absorbing cavity 110. The limiter reinforcement 20 includes a base plate 210, a welding plate 220 and a screw plate 230. The base plate 210 is connected to the welding plate 220 and the screw plate 230 respectively. The welding plate 220 is used to be welded and fixed to the pillar body 10, and the screw plate 230 is used to be screwed and fixed to the pillar body 10.

[0033] The column body 10 is usually surrounded by an outer plate, an inner plate and a reinforcement plate to form an energy absorption cavity 110. The traditional limiter reinforcement plate 2210 is welded to the multiple inner wall surfaces of the column body 10 through multiple welding surfaces. Welding deviations are likely to occur during welding, resulting in gaps and other deviations between the welding surface of the limiter reinforcement plate 2210 and the inner wall surface of the column body 10, making it difficult to weld to the column body 10, resulting in insufficient connection strength between the column body 10 and the limiter reinforcement plate 2210, poor assembly accuracy and difficulty in assembly. The welding plate 220 and the screw plate 230 are connected and fixed to the column body 10 by welding and screwing. The welding plate 220 is first welded to the inner wall of the column body 10. Even if the welding deviation causes a gap or other deviation between the screw plate 230 and the column body 10 and welding is impossible, the screw plate 230 can also be connected to the column body 10 by bolts, so that the screw plate 230 can absorb the deviation generated during welding of the welding plate 220, thereby improving the assembly accuracy and connection strength of the limiter reinforcement 20 and the column body 10 and reducing the difficulty of assembly.

[0034] See also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the first-view structure of the limiter reinforcement provided by this application. Figure 3 This is a schematic structural diagram of the limiter reinforcement provided in this application from a second perspective.

[0035] The welding plate 220 is connected to a portion of the circumference of the bottom plate 210 by bending, and the screwing plate 230 is connected to at least a portion of the remaining circumference of the bottom plate 210 by bending. The bending directions of the welding plate 220 and the screwing plate 230 relative to the bottom plate 210 are opposite.

[0036] The welding plate 220, the screwing plate 230, and the base plate 210 are bent and connected, allowing the limiter reinforcement 20 to bend and extend in different directions. This helps to improve the torsional rigidity of the limiter reinforcement 20, making the connection between the limiter and the vehicle pillar 1 stronger, while also increasing the rigidity of the vehicle pillar 1. The welding plate 220 extends toward one side of the base plate 210, while the screwing plate 230 extends toward the other side of the base plate 210. This allows the screwing plate 230 to leave space for the welding plate 220, making welding easier. At the same time, along the circumferential direction of the base plate 210, one end of the screwing plate 230 is adjacent to one end of the welding plate 220, while the other end of the screwing plate 230 is spaced apart from the other end of the welding plate 220, further leaving space for the welding plate 220 to avoid during operation.

[0037] The welding plate 220 includes multiple sub-welding plates 2220, which are sequentially connected along the circumference of the base plate 210. The welding plate 220 is welded to the inner sidewall and bottom wall of the column body 10. The provision of multiple sub-welding plates 2220 allows the stopper reinforcement 20 to better adapt to the topography of the column body 10. By adjusting the angle between the sub-welding plates 2220 and the base plate 210 and the topography of the sub-welding plates 2220, the stopper reinforcement 20 and the column body 10 can be adapted to each other for a better connection. The multiple sub-welding plates 2220 can be connected by partially overlapping welding.

[0038] At least one of the multiple sub-welded plates 2220 is a stopper reinforcement plate 2210, which is welded to the inner sidewall of the pillar body 10. The stopper reinforcement plate 2210 is used to strengthen the connection between the stopper and the vehicle pillar 1. It has threaded holes and is connected to the stopper via bolts, connecting the stopper and the stopper reinforcement member 20 as a whole, thereby strengthening the connection between the stopper.

[0039] The limiter reinforcement plate 2210 includes a connected limit body part 2211 and a limit connection part 2212. The limit body part 2211 is bent and connected to the base plate 210, and is welded and fixed to the inner wall of the column body 10. The limit connection part 2212 is bent and connected to the limit body part 2211 on the peripheral side of the base plate 210, and is welded and fixed to the adjacent sub-welding plate 2220. The limiting connection part 2212 can make the limiter reinforcement plate 2210 bend and extend in different directions, so that the torsional stiffness of the limiter reinforcement plate 2210 is improved, and the strength of the connection between the limiter and the vehicle pillar 1 is further strengthened. At the same time, when the limiting body part 2211 is adjusted to adapt to the shape of the pillar body 10 by adjusting the angle between the limiting connection part 2212 and other sub-welding plates 2220, the overlapping area of ​​the limiting connection part 2212 and other sub-welding plates 2220 can be adjusted to adapt to the gap between the limiting body part 2211 and other sub-welding plates 2220. In order to facilitate the adjustment of the welding gap between the limiter reinforcement plate 2210 and other sub-welding plates 2220, the limiting connection part 2212 can be set to be not connected to the bottom plate 210. Preferably, in the circumferential direction of the bottom plate 210, limiting connection parts 2212 are provided on both sides of the limiting body part 2211, the limiting connection parts 2212 and the limiting body part 2211 are integrally provided, and the limiting connection parts 2212 on both sides are welded to the sub-welding plate 2220.

[0040] The bottom plate 210 includes two central ridges 2110, which are arranged crosswise. The intersection of the two central ridges 2110 is centered on the surface of the bottom plate 210. The central ridges 2110 protrude from the bottom plate 210, allowing the bottom plate 210 to extend in different directions. The central ridges 2110 function as reinforcing ribs, thereby increasing the torsional rigidity of the bottom plate 210. Preferably, one central ridge 2110 can extend toward the stopper reinforcement plate 2210, while the other central ridge 2110 can extend toward the screw connection plate 230. One end of the central ridge 2110 can connect to the bent connection between the screw connection plate 230 and the bottom plate 210 to increase the rigidity of the screw connection plate 230. The number and extension direction of the central ridges 2110 can be adjusted according to actual conditions.

[0041] The base plate 210 has an outer flange 2120, which surrounds the two central ridges 2110. A plurality of first grooves 2130 are formed between the outer flange 2120 and the two central ridges 2110. At least one first groove 2130 is provided with at least one first weight-reducing hole 2150 extending through opposing surfaces of the base plate 210. The base plate 210 has an upper surface facing the weld. A groove is formed on the upper surface, recessed inward in the direction of the bend of the screw plate 230. The sidewalls of the groove form the outer flange 2120. This creates a step between the bottom and upper surfaces of the groove, allowing the base plate 210 to extend in different directions and further enhancing its torsional rigidity. Two central ridges 2110 connect the outer flange 2120, dividing the groove formed therearound into multiple sections, thereby forming a plurality of first grooves 2130. The thickness of the bottom plate 210 decreases at the grooves formed around the outer flange 2120, thereby reducing weight, but at the same time reducing stiffness. The provision of central ridges 2110 thereon can compensate for the loss of stiffness at this location, thereby achieving both weight reduction and stiffness requirements. To further reduce weight, first weight-reducing holes 2150 are provided within the first grooves 2130. The thickness of the bottom plate 210 decreases at the grooves formed around the outer flange 2120. To avoid affecting the connection strength between the welding plate 220 and the column body 10, the outer flange 2120 and the welding plate 220 are preferably spaced apart.

[0042] A second groove 2140 is formed at the connection between the outer flange portion 2120 and at least one of the two middle ridges 2110, and a second weight-reducing hole 2160 is provided in the second groove 2140. In order to further reduce weight, a second weight-reducing hole 2160 is provided at the connection between the middle ridge 2110 and the outer flange portion 2120. The second weight-reducing hole 2160 is surrounded by the middle ridge 2110 and the outer flange portion 2120. The second weight-reducing hole 2160 reduces the connection area between the middle ridge 2110 and the outer flange portion 2120, and the stiffness here is reduced. Therefore, the number of the second weight-reducing holes 2160 can be adjusted according to the actual situation by weighing the stiffness and weight-reduction requirements. Preferably, second weight-reducing holes 2160 are provided at both ends of the connection between one of the middle ridges 2110 and the outer flange portion 2120.

[0043] A third weight-reducing hole 2170 passing through the middle ridges 2110 is provided at the intersection of the two middle ridges 2110. The third weight-reducing hole 2170 is provided to further reduce the weight. The two middle ridges 2110 cross at the third weight-reducing hole 2170 to extend in different directions, and the bottom plate 210 at the middle ridges 2110 is thicker. Therefore, the third weight-reducing hole 2170 will not have a significant impact on the stiffness. The weight-reducing hole can be preferentially provided here to reduce the weight of the limiter reinforcement 20.

[0044] To sum up, the limiter reinforcement 20 of the vehicle pillar 1 of the present application is provided with a welding plate 220 and a screwing plate 230 to connect to the pillar body 10. The limiter reinforcement 20 is installed by welding and screwing. The screwing plate 230 can absorb welding deviations, thereby improving assembly accuracy and reducing assembly difficulty; the screwing plate 230 and the welding plate 220 have opposite bending directions and the arrangement of multiple sub-welding plates 2220 facilitates operation and installation. The arrangement of the middle ridge 2110 and the outer flange portion 2120 helps to improve the rigidity of the limiter reinforcement 20 and the vehicle pillar 1, and the arrangement of the weight-reducing holes helps to reduce the weight of the limiter reinforcement 20.

[0045] The present application also provides a vehicle, which includes the above-mentioned vehicle pillar 1.
