[0031] Combination Figure 1-Figure 2 The embodiment of the present application provides a vehicle body, including a crossbeam assembly 100, a sill beam assembly 200, an A-pillar assembly 300 and a floor 500. The crossbeam assembly 100 is arranged along the width direction of the vehicle body, the sill beam assembly 200 is arranged along the length direction of the vehicle body, and the A-pillar assembly 300 is arranged along the height direction of the vehicle body. The crossbeam assembly 100, the sill beam assembly 200 and the A-pillar assembly 300 are vertically connected to each other.

[0032] Specifically, combined Figure 3 and Figure 4The crossbeam assembly 100 includes a crossbeam body 110, a crossbeam joint 120 and a reinforcement structure 130. The crossbeam joint 120 is arranged at the end of the crossbeam body 110. A first installation groove is formed inside the crossbeam joint 120. The reinforcement structure 130 is arranged in the first installation groove, and the reinforcement structure 130 is connected to the inner wall of the first installation groove and the crossbeam body 110; the end of the sill beam assembly 200 is connected to the crossbeam joint 120 and the reinforcement structure 130, that is, part of the sill beam assembly 200 is connected to the crossbeam joint 120, and part of the sill beam assembly 200 is connected to the reinforcement structure 130.

[0033] A vehicle body provided in an embodiment of the present application has a first installation groove formed in a cross beam joint 120, a reinforcing structure 130 is arranged in the first installation groove, and the reinforcing structure 130 is connected to the inner wall of the first installation groove, the cross beam body 110, and the threshold beam assembly 200. Therefore, the arrangement of the reinforcing structure 130 strengthens the connection strength between the cross beam joint 120 and the cross beam body 110 and the threshold beam assembly 200, and improves the stiffness and strength at the cross beam joint 120, thereby improving the stiffness and strength of the A-pillar floor area of ​​the vehicle body.

[0034] In some embodiments, the reinforcement structure 130 includes a first reinforcement plate 131, two second reinforcement plates 132, and two third reinforcement plates 133. The two second reinforcement plates 132 are disposed on both sides of the first reinforcement plate 131 along the length direction of the vehicle body, and the two third reinforcement plates 133 are disposed on both sides of the first reinforcement plate 131 along the width direction of the vehicle body. The first reinforcement plate 131 and the two second reinforcement plates 132 are connected to the cross beam joint 120, one of the third reinforcement plates 133 is connected to the cross beam body 110, and the other third reinforcement plate 133 is connected to the sill beam assembly 200, thereby realizing the connection between the reinforcement structure 130 and the cross beam assembly 100 and the sill beam assembly 200.

[0035] Of course, the third reinforcing plate 133 close to one side of the cross beam body 110 is connected to the cross beam body 110 , and the third reinforcing plate 133 close to one side of the sill beam assembly 200 is connected to the sill beam assembly 200 .

[0036] In some embodiments, in combination Figure 1-Figure 5The beam joint 120 includes a first bottom plate 121 and first side plates 122 disposed on both sides of the first bottom plate 121. The first bottom plate 121 and the two first side plates 122 form a first mounting groove. The first reinforcing plate 131 is connected to the first bottom plate 121. The two second reinforcing plates 132 are connected to the first side plates 122 on the same side. The beam body 110 includes a second bottom plate 111 and second side plates 112 disposed on both sides of the second bottom plate 111. The first bottom plate 121 is connected to the second bottom plate 111. The first side plate 122 is connected to the second side plate 112 on the same side, thereby realizing the connection between the beam body 110 and the beam joint 120, and the third reinforcing plate 133 close to the beam body 110 is connected to the second bottom plate 111.

[0037] The crossbeam body 110 is a continuous structure. The crossbeam body 110 and the crossbeam joint 120 together form a U-shaped cross-section beam. When the floor 500 is connected to the first crossbeam assembly 100, a U-shaped beam structure connecting the left and right side sill beam assemblies 200 of the vehicle body is formed, thereby improving the overall rigidity of the vehicle body.

[0038] The first reinforcing plate 131 can be connected to the first bottom plate 121 through a connecting member 140. The connecting member 140 is made of a rigid material, and the connecting component 400 is hollow inside, thereby further improving the strength and rigidity of the connection point between the chassis and the body. Specifically, the connecting member 140 can be made of a steel pipe, and the two ends of the connecting member 140 are respectively welded to the first bottom plate 121 and the first reinforcing plate 131.

[0039] Since the connecting member 140 is provided between the first reinforcing plate 131 and the first bottom plate 121, in order to ensure the connection area between the second reinforcing plate 132 and the first side plate 122, the first side plate 122 can be provided lower than the second bottom plate 111, and the first reinforcing plate 131 is also provided lower than the second bottom plate 111, and the third reinforcing plate 133 close to the beam body 110 is smoothly connected to the second bottom plate 111. Specifically, a lap plate 134 can be provided on one side of the third reinforcing plate 133 close to the beam body 110, connected to the second bottom plate 111 through the lap plate 134, and the lap plate 134 is smoothly connected to the second bottom plate 111.

[0040] In some embodiments, the sill beam assembly 200 includes a sill beam body 210 and a sill beam joint 220 disposed at the end of the sill beam, and the A-pillar assembly 300 includes an A-pillar body 310 and an A-pillar joint 320 disposed at the bottom of the A-pillar body 310. One side of the sill beam joint 220 is connected to the cross beam joint 120 and the reinforcement structure 130, and the other side is connected to the A-pillar joint 320. The sill beam joint 220 and the A-pillar joint 320 are connected to form a closed cavity. Since the closed cavity has a large strength, the strength of the A-pillar floor area can be further improved.

[0041] Specifically, the sill beam joint 220 is provided with a first connecting groove, the A-pillar joint 320 is provided with a second connecting groove, and the first connecting groove and the second connecting groove are connected to form a closed cavity.

[0042] In some embodiments, the sill beam joint 220 includes a first inner portion 221 arranged horizontally and a second inner portion 222 arranged vertically, and the first inner portion 221 is connected to the sill beam body 210; the A-pillar joint 320 includes a first outer portion 321 arranged horizontally and a second outer portion 322 arranged vertically, and the second outer portion 322 is connected to the A-pillar body 310, that is, the sill beam joint 220 and the A-pillar joint 320 are both "L"-shaped, and the first inner portion 221 is connected to the first outer portion 321, and the second inner portion 222 is connected to the second outer portion 322 to form an "L"-shaped closed cavity.

[0043] Since the sill beam joint 220 and the A-pillar joint 320 are connected to form an "L"-shaped closed cavity, the sill beam assembly 200 and the A-pillar assembly 300 are connected in both the horizontal and vertical directions, further enhancing the connection strength.

[0044] In some embodiments, a second mounting groove is further formed in the cross beam joint 120, and at least a portion of the outer surface of the threshold beam joint 220 is connected to the inner wall of the second mounting groove, that is, at least a portion of the outer surface of the threshold beam joint 220 is consistent with the shape of the inner wall of the second mounting groove to achieve the connection between the threshold beam joint 220 and the cross beam joint 120.

[0045] Specifically, the beam joint 120 further includes a first connecting plate 160 and a second connecting plate 170, wherein the first connecting plate 160 is connected to the first side plate 122 disposed outside the beam joint 120, and the second connecting plate 170 is connected to the first bottom plate 121, and the first connecting plate 160 and the second connecting plate 170 form a second mounting groove. The first connecting plate 160 can be regarded as a portion extending from the first side plate 122, and the second connecting plate 170 can be regarded as a portion extending from the first bottom plate 121, that is, the first connecting plate 160 is integrally provided with the first side plate 122, and the second connecting plate 170 is integrally provided with the first bottom plate 121.

[0046] It is conceivable that, since the first connection groove is formed on the side of the sill beam joint 220 facing the A-pillar joint, the side of the sill beam joint 220 away from the A-pillar joint has a protruding structure, and the protruding structure matches the shape of the inner wall of the second installation groove. Specifically, the side area of ​​the sill beam joint 220 away from the sill beam body 210 is connected to the first connection plate 160, the bottom area of ​​the sill beam joint 220 is connected to the second connection plate 170, and the side area of ​​the first connection groove away from the A-pillar joint 320 (i.e., the protruding surface of the sill beam joint 220) is connected to the third reinforcement plate 133 of the reinforcement structure 130.

[0047] It should be noted that in this embodiment, the connection between the cross beam joint 120 and the sill beam joint 220, between the sill beam joint 220 and the A-pillar joint 320, and between the cross beam body 110, the cross beam joint 120, the sill beam joint 220 and the reinforcement structure 130 are all welded.

[0048] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including a chassis, a connecting assembly 400 and the vehicle body described above, wherein one end of the connecting assembly 400 is connected to the chassis, and the other end passes through the bottom surface of the cross beam joint 120 and the reinforcing structure 130 in sequence to connect the chassis and the vehicle body.

[0049] In some embodiments, a plurality of connection points are provided between the chassis and the vehicle body, and a plurality of vehicle body joints 1 for connecting with the vehicle body are provided on the chassis, and a connection assembly 400 is provided corresponding to each vehicle body joint 1, and the vehicle body joint 1 is connected to the vehicle body through the connection assembly 400. The connection assembly 400 includes a suspension 410, a connection bolt 420 and a locking nut 430, and the suspension 410 is assembled on the vehicle body joint 1, and the connection bolt 420 passes through the suspension 410 from the bottom of the vehicle body joint 1 and is screwed to the vehicle body, and then is locked by the locking nut 430, thereby realizing the connection between the vehicle body and the chassis. Specifically in this embodiment, the chassis can be a sliding chassis.

[0050] Specifically, the connecting bolt 420 passes through the first bottom plate 121, the connecting member 140 and the first reinforcing plate 131 in sequence, and the locking nut 430 is arranged on the side of the first reinforcing plate 131 away from the first bottom plate 121, and locks the connecting bolt 420 to achieve the connection between the chassis and the body.

[0051] In some embodiments, a positioning bracket 150 is further provided on the side of the cross beam joint 120 to play a positioning role when the chassis is assembled with the vehicle body.

[0052] In a vehicle provided in an embodiment of the present application, one of the connection points between the chassis and the vehicle body is arranged in the A-pillar floor area of ​​the vehicle body, and the connection point is specifically located at the end of the cross beam assembly 100. Since a first installation groove is formed in the cross beam joint 120, a reinforcement structure 130 is arranged in the first installation groove, and the reinforcement structure 130 is connected to the inner wall of the first installation groove, the cross beam body 110, and the threshold beam assembly 200, the arrangement of the reinforcement structure 130 strengthens the connection strength between the cross beam joint 120 and the cross beam body 110 and the threshold beam assembly 200, and improves the rigidity and strength at the cross beam joint 120, thereby improving the rigidity and strength of the connection point, and ensuring the safety performance of the vehicle body.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
