For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Figure 1 The vehicle body side column assembly of an embodiment of the present invention is shown, and the vehicle body side column assembly can be applied to a vehicle. The vehicle can be a private vehicle, such as a sedan, SUV, MPV or pickup truck, etc.; the vehicle can also be an operating 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.

[0047] It should be noted that the up, down, front, back, left and right directions involved in the present invention refer to the direction of the vehicle in the vehicle O-XYZ coordinate system, the origin O coincides with the center of mass of the vehicle, the front end refers to the X direction parallel to the ground and pointing forward, the rear end refers to the X direction parallel to the ground and pointing backward, the left side refers to the Y direction parallel to the ground and pointing to the left side of the driver, the right side refers to the Y direction parallel to the ground and pointing to the right side of the driver, the upper end refers to the Z direction pointing upwards through the point O, and the lower end refers to the Z direction pointing downwards through the point O.

[0048] Combination Figure 1 and Figure 2 The body side pillar assembly includes a body side pillar 300 and a body side pillar reinforcement structure for reinforcing the structure of the body side pillar 300; wherein the body side pillar 300 includes a pillar 310 and an upper side beam 320 connected to the top of the pillar 310; the body side pillar reinforcement structure includes a reinforcement tube 100 and a reinforcement component 200, at least a portion of the reinforcement tube 100 is arranged in the upper side beam 320, and the reinforcement component 200 is arranged in the pillar 310.

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

[0050] The reinforcing tube 100 may be a hot-formed steel tube, and its material strength may reach 1500 MPa.

[0051] Combination Figure 3 and Figure 4 The reinforcing assembly 200 includes a reinforcing body 210, which is surrounded by a cavity 212, and the top of the reinforcing body 210 has an opening connected to the cavity 212; the bottom end of the reinforcing tube 100 is passed through the opening of the reinforcing body 210 and is connected to the reinforcing body 210.

[0052] It is understandable that, compared with a thin reinforcing plate, the reinforcing body 210 is surrounded by a cavity 212, has a higher structural strength, and can further strengthen the structural strength of the column 310. Specifically, the reinforcing body 210 is vertically arranged and includes a plurality of vertical side panels 211 connected in sequence, the plurality of side panels 211 are connected and surrounded to form a cavity 212, and the top edges of the plurality of side panels 211 are surrounded to form an opening.

[0053] It can also be understood that the reinforcement body 210 is arranged in the pillar 310 and connected to the pillar 310, at least part of the reinforcement tube 100 is arranged in the upper side beam 320, and the bottom end of the reinforcement tube 100 is penetrated through the opening at the top of the reinforcement body 210 and is connected to the reinforcement body 210, and the reinforcement tube 100 and the reinforcement body 210 are connected as a whole. In this way, the upper side beam 320 and the pillar 310 can have more structures for transmitting the force by means of the vehicle body side column reinforcement structure, so that when a certain part is subjected to force, the force can be better diffused to other structures, and the force integrity of the upper side beam 320 and the pillar 310 is improved, thereby improving the overall strength of the vehicle body side column assembly, especially the reinforcement tube 100 in the upper side beam 320 extends to the reinforcement body 210 inside the pillar 310 and is connected to the reinforcement body 210, which can reduce the risk of the upper side beam 320 being bent when the vehicle collides, and improve the reliability of the vehicle body side column.

[0054] like Figure 2 , Figure 5 and Figure 6 As shown, the column 310 includes an outer plate 311 and an inner plate 312 connected to the outer plate 311 .

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

[0056] Specifically, the front and rear edges of the outer plate 311 are both provided with flanges, and the front and rear edges of the inner plate 312 are also provided with flanges. The flange of the front edge of the outer plate 311 overlaps with the flange of the front edge of the inner plate 312 and is fixed by welding, and the flange of the rear edge of the outer plate 311 overlaps with the flange of the rear edge of the inner plate 312 and is 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] Combination Figure 5 and Figure 6 The reinforcement assembly 200 also includes a first connection unit 220 and a second connection unit 230. The reinforcement body 210 is arranged in the inner cavity of the column 310. The first connection unit 220 connects the outer plate 311 and the reinforcement body 210, and the second connection unit 230 connects the inner plate 312 and the reinforcement body 210.

[0058] It is understood that the reinforcement body 210 is disposed in the inner cavity of the pillar 310, and the outer panel 311 is connected to the reinforcement body 210 by the first connection unit 220, and the inner panel 312 is connected to the reinforcement body 210 by the second connection unit 230, so that the structural strength of the entire pillar 310 can be improved. It is also understood that the outer panel 311 and the inner panel 312 are connected to the reinforcement body 210 by means of the first connection unit 220 and the second connection unit 230, respectively, which is equivalent to further connecting the inner panel 312 and the outer panel 311 with the reinforcement assembly 200 as an intermediate component, so that the connection between the inner panel 312 and the outer panel 311 can be made more firm, thereby further improving the reliability of the pillar 310, so that if a vehicle using the above-mentioned body side column assembly collides during driving, the risk of cracking of the weld between the outer panel 311 and the inner panel 312 can be reduced.

[0059] Specifically in this embodiment, the side column of the vehicle body is the A-pillar. When encountering a 25% offset collision condition, the A-pillar can withstand the load generated when the collision occurs, thereby reducing the risk of serious damage to the A-pillar.

[0060] Combination Figure 5 and Figure 7 , defining two side panels 211 as side connecting panels 2111, the two side connecting panels 2111 are spaced apart and arranged opposite to each other along the inward and outward directions of the vehicle body side column assembly, one side connecting panel 2111 is configured to face the inner panel 312, and the other side connecting panel 2111 is configured to face the outer panel 311; one end of the first connecting unit 220 is connected to the outer panel 311, and the other end is passed through the two side connecting panels 2111.

[0061] It can be understood that the first connecting unit 220 passes through the cavity 212 of the reinforcing body 210, and the first connecting unit 220 also passes through the two side connecting plates 2111 of the reinforcing body 210. In this way, 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 panel 311 and reducing the degree of deformation of the outer panel 311.

[0062] Combination Figure 6 and Figure 7 Furthermore, one end of the second connecting unit 230 is connected to the inner plate 312 , and the other end is passed through the two side connecting plates 2111 .

[0063] It is also understandable that the second connecting unit 230 passes through the cavity 212 of the reinforcing body 210, and the second connecting unit 230 also passes through the two side connecting plates 2111 of the reinforcing body 210. In this way, 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 and reducing the degree of deformation of the inner plate 312.

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

[0065] like Figure 5 , Figure 6 As shown, as a further improvement of the above embodiment, the number of the reinforcing bodies 210 is at least two, at least two reinforcing bodies 210 are arranged in parallel along the front-to-back direction of the vehicle body side pillar, and every two adjacent reinforcing bodies 210 are connected to each other. The bottom end of the reinforcing tube 100 is inserted into the cavity 212 of any reinforcing body 210.

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

[0067] Each reinforcement body 210 is connected to the outer plate 311 by at least one first connection unit 220, and each reinforcement body 210 is also connected to the inner plate 312 by at least one second connection unit 230. In this way, when the reinforcement assembly 200 is used as an intermediate component to further connect the inner plate 312 and the outer plate 311, there are more connection points between the reinforcement assembly 200 and the inner plate 312 and the outer plate 311, 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.

[0068] Combination Figure 5 , Figure 8 and Fig. 9 In some embodiments, the reinforcing body 210 is provided with a first assembly hole 210a connected to its cavity 212, and the outer plate 311 is provided with a second assembly hole corresponding to the first assembly hole 210a. The first connecting unit 220 includes a first sleeve 221 and a first fastener 222. The first sleeve 221 is passed through the first assembly hole 210a, and one end of the first sleeve 221 is arranged toward the second assembly hole. The first fastener 222 has a first limit head 2221. The first fastener 222 passes through the second assembly hole and is passed through the first sleeve 221, and the first limit head 2221 is abutted against a side of the outer plate 311 away from the first sleeve 221.

[0069] It can be understood that the first sleeve 221 is inserted into the first assembly hole 210a of the reinforcement body 210 and penetrates the cavity 212 of the reinforcement body 210, and the first sleeve 221 is fixed to the reinforcement body 210 by welding. The first fastener 222 can pass through the second assembly hole and penetrate into the first sleeve 221, and make the first stopper 2221 abut against the side of the outer plate 311 away from the first sleeve 221, so that the reinforcement body 210 and the outer plate 311 can be connected together.

[0070] Among them, the end of the first sleeve 221 close to the outer plate 311 is defined as the first limit end 2211, the first limit end 2211 is set toward the second assembly hole and is against the outer plate 311, the first limit end 2211 and the first limit head 2221 can clamp the outer plate 311 together, which can reduce the risk of loosening of the first connecting unit 220 and the outer plate 311 and has higher reliability.

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

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

[0073] Further, the reinforcing body 210 is provided with two first assembly holes 210a, the two first assembly holes 210a are located on opposite sides of the cavity 212 of the reinforcing body 210, the second assembly hole and the two first assembly holes 210a are aligned with each other, and the first sleeve 221 is simultaneously penetrated through the two first assembly holes 210a of the reinforcing body 210. In this way, the first sleeve 221 can penetrate through the cavity 212 of the reinforcing body 210, and because the first sleeve 221 is penetrated through the two first assembly holes 210a, when the vehicle collides, the hole walls of the two first assembly holes 210a simultaneously provide support for the first connecting unit 220, thereby providing support for the outer panel 311, and the degree of deformation of the outer panel 311 can be reduced.

[0074] Combination Figure 6 , Figure 8 and Fig.10Further, the reinforcing body 210 is provided with a third assembly hole 210b communicating with the cavity 212 thereof, the inner plate 312 is provided with a fourth assembly hole corresponding to the third assembly hole 210b, the second connecting unit 230 includes a second sleeve 231 and a second fastener 232, the second sleeve 231 is passed through the third assembly hole 210b, and one end of the second sleeve 231 is arranged toward the fourth assembly hole, the second fastener 232 has a second stopper 2321, the second fastener 232 passes through the fourth assembly hole and is passed through the second sleeve 231, and the second stopper 2321 is abutted against a side of the inner plate 312 away from the second sleeve 231. In this way, the reinforcing body 210 and the inner plate 312 can be connected together.

[0075] Among them, the end of the second sleeve 231 close to the inner plate 312 is defined as the second limit end 2311, the second limit end 2311 is set toward the fourth assembly hole and against the inner plate 312, the second limit end 2311 and the second limit head 2321 can clamp the inner plate 312 together, which can reduce the risk of loosening of the second connecting unit 230 and the inner plate 312 and has higher reliability.

[0076] It should be noted that the second limiting end 2311 and the second limiting head 2321 may directly abut against the inner plate 312 , or may indirectly abut against the inner plate 312 via other intermediate components.

[0077] Specifically, the second sleeve 231 is provided with an internal thread, the second fastener 232 is a screw, and the second limiting head 2321 is the screw head of the screw.

[0078] Further, the reinforcing body 210 is provided with two third assembly holes 210b, the two third assembly holes 210b are located on opposite sides of the cavity 212 of the reinforcing body 210, the third assembly hole 210b and the two fourth assembly holes are aligned with each other, and the second sleeve 231 is simultaneously penetrated through the two third assembly holes 210b of the reinforcing body 210. In this way, the second sleeve 231 can penetrate through the cavity 212 of the reinforcing body 210, and because the second sleeve 231 is penetrated through the two third assembly holes 210b, when the vehicle collides, the hole walls of the two third assembly holes 210b simultaneously provide support for the second connection unit 230, thereby providing support for the inner plate 312, and the degree of deformation of the inner plate 312 can be reduced.

[0079] Combination Figure 5 and Figure 7 In some embodiments, the inner cavity of the reinforcing body 210 is further provided with a first reinforcing plate 400, and the first reinforcing plate 400 is arranged in contact with the outer plate 311, and one end of the first connecting unit 220 is connected to the reinforcing body 210, and the other end is passed through the outer plate 311 and the first reinforcing plate 400.

[0080] It can be understood that the first reinforcing plate 400 can be welded to the outer panel 311, and the first reinforcing plate 400 can also reinforce the structure of the outer panel 311. In addition, the first connecting unit 220 is simultaneously passed through the outer panel 311 and the first reinforcing plate 400. The outer panel 311 and the first reinforcing plate 400 are stacked to form a double-layer structure. When the vehicle collides, the risk of the first connecting unit 220 being subjected to force and tearing the outer panel 311 can be reduced.

[0081] Combination Figure 5 , Figure 7 and Fig. 9 Specifically, the first reinforcing plate 400 is provided with a fifth assembly hole 410 arranged opposite to the second assembly hole of the outer plate 311 , and the first fastener 222 passes through the second assembly hole and the fifth assembly hole 410 at the same time and is inserted into the first sleeve 221 .

[0082] Combination Figure 6 and Figure 7 Furthermore, the inner cavity of the reinforcing body 210 is also provided with a second reinforcing plate 500, and the second reinforcing plate 500 is arranged in contact with the inner plate 312, and one end of the second connecting unit 230 is passed through the reinforcing body 210, and the other end is passed through the inner plate 312 and the second reinforcing plate 500.

[0083] It can be understood that the second reinforcing plate 500 can be welded to the inner panel 312, and the second reinforcing plate 500 can also reinforce the structure of the inner panel 312. At the same time, the second connecting unit 230 is penetrated by the inner panel 312 and the second reinforcing plate 500. The inner panel 312 and the second reinforcing plate 500 are stacked to form a double-layer structure. When the vehicle collides, the risk of the second connecting unit 230 being subjected to force and tearing the inner panel 312 can be reduced.

[0084] Combination Figure 6 , Figure 7 and Fig.10 Specifically, the second reinforcing plate 500 is provided with a sixth assembly hole arranged opposite to the fourth assembly hole of the inner plate 312 , and the second fastener 232 passes through the fourth assembly hole and the sixth assembly hole at the same time and is inserted into the second sleeve 231 .

[0085] like 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 passing through it are also relatively lower, and will be closer to the tire of the vehicle. When the vehicle collides, the tire exerts 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, which can reduce the risk of the first connecting unit 220 and the second connecting unit 230 on the shorter reinforcing body 210 tearing the outer plate 311 and the inner plate 312.

[0086] like Figure 4 As shown, in some embodiments, the vehicle body side column reinforcement structure also includes a third connection unit 240, which is penetrated through the reinforcement body 210 and through the portion of the reinforcement tube 100 extending into the cavity 212, and the third connection unit 240 is used to connect the reinforcement body 210 with the reinforcement tube 100.

[0087] Specifically in this embodiment, the third connecting unit 240 is the above-mentioned first connecting unit 220. The lower end of the reinforcing tube 100 is provided with a seventh assembly hole 110 corresponding to the first assembly hole 210a. The first connecting unit 220 is passed through the seventh assembly hole 110, and the first connecting unit 220 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 with the help of the first connecting unit 220.

[0088] More specifically, the first sleeve 221 is simultaneously passed through the first assembly hole 210a of the reinforcing body 210 and the seventh assembly hole 110 of the reinforcing tube 100, and the first sleeve 221 is welded to the reinforcing body 210 and the reinforcing tube 100, and the first fastener 222 passes through the second assembly hole of the outer plate 311 and is passed into the first sleeve 221, which can achieve the effect 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 may be the above-mentioned second connecting unit 230, the reinforcing tube 100 may be provided with an eighth assembly hole corresponding to the third assembly hole 210b, the second connecting unit 230 is also passed through the eighth assembly 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 achieved with the aid of the second connecting unit 230.

[0090] It should be noted that, in other embodiments, the third connection unit 240 may also be a component used alone to connect the strong body 210 to the reinforcing tube 100 , and may not be connected to the column 310 .

[0091] The present invention further provides a vehicle, comprising the vehicle body side column assembly of the above embodiment.

[0092] Among them, the vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck; the vehicle can also be an operating 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 present invention has the above-mentioned body side pillar assembly. In the body side pillar assembly, compared with a thin reinforcement plate, the reinforcement body 210 is surrounded by a cavity 212, which has higher structural strength and can further strengthen the structural strength of the pillar 310. In addition, the reinforcement body 210 is arranged in the pillar 310 and connected to the pillar 310, at least part of the reinforcement tube 100 is arranged in the upper side beam 320, and the bottom end of the reinforcement tube 100 is passed through the opening at the top of the reinforcement body 210 and is arranged in the cavity 212 and connected to the reinforcement body 210, and the reinforcement tube 100 and the reinforcement body 210 are connected to form a whole. In this way, with the help of the body side column reinforcement structure, there are more structures for transmitting force between the upper side beam 320 and the pillar 310, so that when a certain part is subjected to force, the force can be better diffused to other structures, thereby improving the force integrity of the upper side beam 320 and the pillar 310, thereby improving the overall strength of the body side column assembly, especially the reinforcement tube 100 in the upper side beam 320 extends into the reinforcement body 210 inside the pillar 310 and is connected to the reinforcement body 210, which can reduce the risk of the upper side beam 320 being bent when the vehicle collides, thereby improving the reliability of the body side column.
