[0048] In combination Figure 1 With Figure 2 , the body side pillar assembly comprises a body side pillar 300 and a body side pillar reinforcing structure for reinforcing the structure of the body side pillar 300; wherein the body side pillar 300 comprises a column 310 and an upper side beam 320 connected to the top end of the column 310; the body side pillar reinforcing structure comprises a reinforcing pipe 100 and a reinforcing assembly 200, at least part of the reinforcing pipe 100 is arranged in the upper side beam 320, and the reinforcing assembly 200 is arranged in the column 310.

[0049] As Figure 2 shown, it can be understood that the reinforcing assembly 200 can reinforce the structure of the column 310, and the reinforcing pipe 100 can reinforce the structure of the upper side beam 320, thereby improving the strength of the entire body side pillar.

[0050] Wherein the reinforcing pipe 100 can be a hot-formed steel pipe, and the material strength thereof can reach 1500MPa.

[0051] In combination Figure 3 With Figure 4 , the reinforcing assembly 200 comprises a reinforcing body 210, the reinforcing body 210 is surrounded to form a cavity 212, and the top end of the reinforcing body 210 has an opening communicating with the cavity 212; the bottom end of the reinforcing pipe 100 is arranged in the cavity 212 through the opening of the reinforcing body 210 and connected with the reinforcing body 210.

[0052] It can be understood that compared with a single thin reinforcing plate, the reinforcing body 210 is surrounded to form a cavity 212, and the structural strength is higher, which can further strengthen the structural strength of the column 310. Specifically, the reinforcing body 210 is vertically arranged and comprises a plurality of vertical side plates 211 connected in sequence, the plurality of side plates 211 are connected and surrounded to form the cavity 212, and the top edges of the plurality of side plates 211 are surrounded to form the opening.

[0053] In addition, it can be understood that the reinforcing body 210 is arranged in and connected with the pillar 310, at least part of the reinforcing pipe 100 is arranged in the upper side beam 320, and the bottom end of the reinforcing pipe 100 is arranged in the cavity 212 through the opening at the top of the reinforcing body 210 and connected with the reinforcing body 210, and the reinforcing pipe 100 and the reinforcing body 210 are connected as a whole. In this way, the vehicle body side column reinforcing structure can make the upper side beam 320 and the pillar 310 have more force transmission structures, so that when a certain part is subjected to force, the force can be better dispersed to other structures, improving the force integrity of the upper side beam 320 and the pillar 310, thereby improving the overall strength of the vehicle body side column assembly, and especially the reinforcing pipe 100 in the upper side beam 320 extends into the reinforcing body 210 in the pillar 310 and is connected together, which can reduce the risk of bending of the upper side beam 320 when the vehicle is in a collision, and improve the reliability of the vehicle body side column.

[0054] As shown in Figure 2 , Figure 5 and Figure 6 , the pillar 310 includes an outer plate 311 and an inner plate 312 connected with the outer plate 311.

[0055] It should be noted that the "inner" refers to the side close to the passenger cabin, and the "outer" is opposite to the "inner" and refers to the side away from the passenger cabin; the outer plate 311 and the inner plate 312 of the pillar 310 are connected together and jointly define an inner cavity.

[0056] Specifically, the front edge and the rear edge of the outer plate 311 are provided with flanges, and the front edge and the rear edge of the inner plate 312 are also provided with flanges, the flanges of the front edge of the outer plate 311 and the flanges of the front edge of the inner plate 312 are overlapped and fixed by welding, and the flanges of the rear edge of the outer plate 311 and the flanges of the rear edge of the inner plate 312 are overlapped and fixed by welding. When the outer plate 311 and the inner plate 312 are assembled, the outer plate 311 and the inner plate 312 cooperate to form a hollow structure with an inner cavity.

[0057] In combination with Figure 5 and Figure 6 , the reinforcing assembly 200 further includes a first connecting unit 220 and a second connecting unit 230, the reinforcing body 210 is arranged in the inner cavity of the pillar 310, the first connecting unit 220 connects the outer plate 311 and the reinforcing body 210, and the second connecting unit 230 connects the inner plate 312 and the reinforcing body 210.

[0058] It can be understood that the reinforcing body 210 is arranged in the inner cavity of the column 310, and the outer plate 311 and the reinforcing body 210 are connected by the first connecting unit 220, and the inner plate 312 and the reinforcing body 210 are connected by the second connecting unit 230, which can improve the structural strength of the entire column 310. In addition, it can be understood that the outer plate 311 and the inner plate 312 are connected to the reinforcing body 210 by the first connecting unit 220 and the second connecting unit 230, respectively, which is equivalent to further connecting the inner plate 312 and the outer plate 311 by taking the reinforcing assembly 200 as an intermediate component, which can make the connection between the inner plate 312 and the outer plate 311 more firm, thereby further improving the reliability of the column 310, so that if a vehicle applied with the above-mentioned body side column assembly collides during driving, the risk of cracking of the welding points between the outer plate 311 and the inner plate 312 can be reduced.

[0059] Specifically in this embodiment, the body side column is an A column, which can withstand the load generated when a collision occurs and reduce the risk of serious damage to the A column when a 25% offset collision condition is encountered.

[0060] In combination Figure 5 With Figure 7 , it is defined that two side plates 211 are side connecting plates 2111, which are spaced apart and oppositely arranged along the inner and outer directions of the body side column assembly, one of which is configured to face the inner plate 312, and the other is configured to face the outer plate 311; one end of the first connecting unit 220 is connected to the outer plate 311, and the other end penetrates the two side connecting plates 2111.

[0061] It can be understood that the first connecting unit 220 penetrates the cavity 212 of the reinforcing body 210, and the first connecting unit 220 penetrates the two side connecting plates 2111 of the reinforcing body 210 at the same time, so that when the vehicle collides, the two side connecting plates 2111 simultaneously provide support for the first connecting unit 220, thereby providing support for the outer plate 311, reducing the degree of deformation of the outer plate 311.

[0062] In combination Figure 6 With Figure 7 Further, one end of the second connecting unit 230 is connected to the inner plate 312, and the other end penetrates the two side connecting plates 2111.

[0063] It can also be understood that the second connecting unit 230 penetrates the cavity 212 of the reinforcing body 210, and the second connecting unit 230 penetrates the two side connecting plates 2111 of the reinforcing body 210 at the same time, so that when the vehicle collides, the two side plates 211 simultaneously provide support for the second connecting unit 230, thereby providing support for the inner plate 312, reducing the degree of deformation of the inner plate 312.

[0064] It should be noted that the reinforcing body 210 can be manufactured by a rolling process, and the reinforcing body 210 is made of high-strength steel, and the structural strength of the reinforcing body 210 is between 800 MPa and 1500 MPa.

[0065] As shown in Figure 5 , Figure 6 , as a further improvement of the above embodiment, the number of reinforcing bodies 210 is at least two, and at least two reinforcing bodies 210 are arranged side by side along the front-rear direction of the side column of the vehicle body, and each adjacent two reinforcing bodies 210 are connected to each other. Among them, the bottom end of the reinforcing pipe 100 is arranged in the cavity 212 of any reinforcing body 210.

[0066] It can be understood that each adjacent two reinforcing bodies 210 can be fixed together by welding or using screws. By increasing the number of reinforcing bodies 210, the structural strength of the entire reinforcing assembly 200 can be further improved.

[0067] Among them, each reinforcing body 210 is connected to the outer plate 311 by at least one first connecting unit 220, and each reinforcing body 210 is also connected to the inner plate 312 by at least one second connecting unit 230. In this way, when the reinforcing assembly 200 is used as an intermediate component to further connect the inner plate 312 and the outer plate 311, the connection points between the reinforcing assembly 200 and the inner plate 312 and the outer plate 311 are more, which can further make the connection between the inner plate 312 and the outer plate 311 more firm, thereby further improving the reliability of the column 310.

[0071] It should be noted that the first limiting end 2211 and the first limiting head 2221 can directly abut against the outer plate 311, or indirectly abut against the outer plate 311 through other intermediate members.

[0072] Wherein, the first sleeve 221 is provided with an internal thread, the first fastener 222 is a screw, and the first limiting head 2221 is a screw head of the screw.

[0080] It can be understood that the first reinforcing plate 400 can be welded on the outer plate 311, the first reinforcing plate 400 can also strengthen the structure of the outer plate 311, in addition, the first connecting unit 220 is simultaneously provided in the outer plate 311 and the first reinforcing plate 400, and the outer plate 311 and the first reinforcing plate 400 are stacked to form a double-layer structure, so that the risk of tearing the outer plate 311 by the first connecting unit 220 under stress when the vehicle collides can be reduced.

[0081] In combination with Figure 5 , Figure 7 and Figure 9 , specifically, the first reinforcing plate 400 is provided with a fifth assembly hole 410 opposite to the second assembly hole of the outer plate 311, and the first fastener 222 simultaneously passes through the second assembly hole and the fifth assembly hole 410 and is provided into the first sleeve 221.

[0082] In combination with Figure 6 and Figure 7 , further, the inner cavity of the reinforcing body 210 is also provided with a second reinforcing plate 500, the second reinforcing plate 500 is attached to the inner plate 312, one end of the second connecting unit 230 is provided in the reinforcing body 210, and the other end is provided in the inner plate 312 and the second reinforcing plate 500.

[0083] It can be understood that the second reinforcing plate 500 can be welded on the inner plate 312, the second reinforcing plate 500 can also strengthen the structure of the inner plate 312, and at the same time, the second connecting unit 230 is provided in the inner plate 312 and the second reinforcing plate 500, and the inner plate 312 and the second reinforcing plate 500 are stacked to form a double-layer structure, so that the risk of tearing the inner plate 312 by the second connecting unit 230 under stress when the vehicle collides can be reduced.

[0084] In combination with Figure 6 , Figure 7 and Figure 10 , specifically, the second reinforcing plate 500 is provided with a sixth assembly hole opposite to the fourth assembly hole of the inner plate 312, and the second fastener 232 simultaneously passes through the fourth assembly hole and the sixth assembly hole and is provided into the second sleeve 231.

[0085] As Figure 5As shown, specifically in this embodiment, there are two reinforcing bodies 210, one of which is shorter than the other. For the shorter reinforcing body 210, the positions of the first connecting unit 220 and the second connecting unit 230 are also relatively lower, closer to the vehicle's tires. When a collision occurs, the tires exert a greater force on the first connecting unit 220 and the second connecting unit 230 connected to the shorter reinforcing body 210. The first reinforcing plate 400 and the second reinforcing plate 500 cover the connection positions of the first connecting unit 220 and the second connecting unit 230 on the shorter reinforcing body 210, reducing the risk of the first connecting unit 220 and the second connecting unit 230 tearing the outer plate 311 and the inner plate 312.

[0086] like Figure 4 As shown, in some embodiments, the vehicle body side pillar reinforcement structure further includes a third connecting unit 240, which passes through the reinforcing body 210 and through the portion of the reinforcing tube 100 that extends into the cavity 212. The third connecting unit 240 is used to connect the reinforcing body 210 and the reinforcing tube 100.

[0087] Specifically, in this embodiment, the third connecting unit 240 is the first connecting unit 220 mentioned above. The lower end of the reinforcing tube 100 is provided with a seventh mounting hole 110 corresponding to the first mounting hole 210a. The first connecting unit 220 passes through the seventh mounting hole 110 and is also welded to the reinforcing tube 100. In this way, the connection between the reinforcing tube 100 and the reinforcing body 210 can be achieved by means of the first connecting unit 220.

[0088] More specifically, the first sleeve 221 is simultaneously inserted into the first mounting hole 210a of the reinforcing body 210 and the seventh mounting hole 110 of the reinforcing tube 100, and the first sleeve 221 is welded to the reinforcing body 210 and the reinforcing tube 100. The first fastener 222 passes through the second mounting hole of the outer plate 311 and is inserted into the first sleeve 221, which can achieve the function of connecting the reinforcing tube 100, the outer plate 311 and the reinforcing body 210 together.

[0089] Of course, in other embodiments, the third connecting unit 240 can be the second connecting unit 230 described above, the reinforcing tube 100 can be provided with an eighth mounting hole corresponding to the third mounting hole 210b, the second connecting unit 230 is also provided through the eighth mounting hole, and the second connecting unit 230 is also welded to the reinforcing tube 100. In this way, the connection between the reinforcing tube 100 and the reinforcing body 210 can be realized by means of the second connecting unit 230.

[0090] It should be noted that in other embodiments, the third connecting unit 240 can also be a component for connecting the reinforcing body 210 and the reinforcing pipe 100 alone, and can not be connected with the stand column 310.

[0091] The application also provides a vehicle comprising the vehicle body side stand column assembly of the above embodiments.

[0092] The vehicle can be a private car, such as a sedan, an SUV, an MPV, or a pickup truck, etc. The vehicle can also be a commercial vehicle, such as a van. The vehicle can be a gasoline 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.

[0093] The vehicle of the application has the vehicle body side stand column assembly described above. In the vehicle body side stand column assembly, compared with a thin reinforcing plate, the reinforcing body 210 is surrounded to form a cavity 212, and has higher structural strength, which can further strengthen the structural strength of the stand column 310. In addition, the reinforcing body 210 is arranged in the stand column 310 and connected with the stand column 310, at least part of the reinforcing pipe 100 is arranged in the upper side beam 320, and the bottom end of the reinforcing pipe 100 is arranged in the cavity 212 through the opening at the top of the reinforcing body 210 and connected with the reinforcing body 210, the reinforcing pipe 100 and the reinforcing body 210 are connected as a whole. In this way, the vehicle body side stand column reinforcing structure can make the upper side beam 320 and the stand column 310 have more force transmission structures, so that when a certain part is subjected to force, the force can be better dispersed to other structures, improving the force integrity of the upper side beam 320 and the stand column 310, thereby improving the overall strength of the vehicle body side stand column assembly. In particular, the reinforcing pipe 100 in the upper side beam 320 extends into the reinforcing body 210 in the stand column 310 and is connected together with the reinforcing body 210, which can reduce the risk of the upper side beam 320 being bent when the vehicle is in a collision, and improve the reliability of the vehicle body side stand column.
