[0036] The application will be further described below in conjunction with the drawings and specific embodiments:

[0037] As shown in FIGS. 1, 2, and 3, the mounting structure of the rear anti-collision frame of the van according to the first embodiment of the application comprises a chassis 10 and a rear anti-collision frame 30. A rocker 20 is arranged at the rear end of the chassis 10. The rocker 20 is made by welding together a plurality of plates. Specifically, the rocker 20 comprises a rocker side wall 21, a rocker top wall 22, and a rocker bottom wall 23. The rocker side wall 21 extends vertically and is located at the outer side of the rocker 20. The rocker top wall 22 and the rocker bottom wall 23 are both welded to the inner side of the rocker side wall 21. The rocker top wall 22 and the rocker bottom wall 23 are offset in the height direction by a certain distance, so that the rocker 20 forms a beam extending in the width direction of the chassis 10 (i.e., the Y direction in the drawings). The rear anti-collision frame 30 comprises two brackets 301 and a cross beam 33 connected to the two brackets 301. Each bracket 301 comprises a web 31 and a connecting plate 32. The connecting plate 32 is located at the rear side of the web 31. The connecting plate 32 can be integrally formed with the web 31.

When the rear anti-collision frame 30 is installed, the connecting plate 32 is arranged between the two limiting portions 243, so that the connecting plate 32 abuts against the second connecting portion 242. Then, the first bolts pass through the web 31 and the chassis 10. Subsequently, the second bolts pass through the second connecting portion 242 and the connecting plate 32.

[0038] In the embodiment one, the supports 301 of the rear anti-collision beam 30 are fixed to the underframe 10 and the rocker 20 by the first bolts 40 and the second bolts 50 respectively, so that the rear anti-collision beam 30 is detachably connected with the underframe 10 and the rocker 20, facilitating replacement and maintenance of the rear anti-collision beam 30; the second bolt 50 connecting the support 301 with the rocker 20 is arranged in the downward groove formed by the opening of the blocking wall 211 and the connecting plate 32, and the lower edge of the blocking wall 211 is lower than the bottom of the second bolt 50, so that the blocking wall 211 shields the second bolt 50 outside, protecting the second bolt 50 from rusting, and shielding the second bolt 50, preventing the second bolt 50 from being exposed, and increasing the aesthetic appearance of the rear of the van.

[0039] The blocking wall 211 is formed by the rocker sidewall 21, that is, the second bolt 50 is shielded by the rocker sidewall 21, specifically, the outer side of the rocker bottom wall 23 is welded and fixed to the inner surface of the rocker sidewall 21, the bottom of the rocker sidewall 21 protrudes downward from the lower surface of the rocker bottom wall 23, and the part of the rocker sidewall 21 protruding from the rocker bottom wall forms the blocking wall 211.

[0040] The underframe 10 is provided with a plurality of bottom cross beams 11 arranged along the length direction of the underframe 10 (i.e. the X direction in the figure), the bottom cross beams 11 extend along the width direction of the underframe 10, and the lower part of the plurality of bottom cross beams 11 is connected with two guide rail beams 12 extending along the length direction of the underframe 10, and the top part of the web plate 31 of the two supports 301 is fixed and connected to the two guide rail beams 12 by the plurality of first bolts 40.

[0041] Referring to Figs. 4, 5, 6 and 7, the rear anti-collision frame 30 comprises two brackets 301 and a cross beam 33. The two brackets 301 are arranged in the width direction of the chassis 10. The web 31 is substantially in the shape of a triangular plate. The web 31 comprises a first edge 311 at the top thereof and extending in the length direction of the chassis, a second edge 312 extending vertically downward from the rear end of the first edge 311, and an inclined edge 313 connecting between the front end of the first edge 311 and the lower end of the second edge 312. The first edge 311 is fixedly connected to the chassis 10 by the first bolts 40, thereby fixing the bracket 301 to the chassis 10. The connecting plate 32 is bent from the second edge 312. The connecting plate 32 is perpendicular to the web 31, and the outer side of the connecting plate 32 extends vertically. The cross beam 33 extends in the width direction of the chassis 10 and is arranged across the outer side of the connecting plate 32. The cross beam 33 comprises a first connecting beam 332 and a second connecting beam 331. The cross sections of the first connecting beam 332 and the second connecting beam 331 are both in the shape of C, i.e. both are formed by bending a plate. The opening of the C-shaped first connecting beam 332 faces outward, and the opening of the C-shaped second connecting beam 331 faces inward. The first connecting beam 332 and the second connecting beam 331 are buckled to each other and fixed by welding. The first connecting beam 332 is fixedly connected to the connecting plate 32 by the bolts 36, so that the first connecting beam 332 is detachably connected to the bracket 301. A through hole 3310 is arranged on the second connecting beam 331. The through hole 3310 is opposite to the bolt 36, and the bolt 36 can pass through the through hole 3310. A reflective sticker 34 is attached to the second connecting beam 331 to cover the through hole 3310.

[0042] The cross beam 33 is connected to the bracket 301 by the bolts 36, so that the cross beam 33 can be conveniently installed to the bracket 301. When the cross beam 33 is damaged, the bolts 36 can be detached, and the cross beam 33 can be detached from the bracket 301. Therefore, only the cross beam 33 needs to be replaced, thereby reducing the maintenance cost of the rear anti-collision frame. In addition, the bolts 36 are hidden in the cross beam 33, so that the cross beam 33 does not protrude from the outer surface of the rear anti-collision frame, and the reflective sticker 34 can be flatly attached to the cross beam 33, thereby improving the appearance of the rear anti-collision frame.

[0043] The first connecting beam 332 comprises a first web 3321 and two first wing plates 3322 respectively located on the upper and lower sides of the first web 3321, and the second connecting beam 331 comprises a second web 3311 and two second wing plates 3312 respectively located on the upper and lower sides of the second web 3311. The first connecting beam 332 and the second connecting beam 331 are both selected from a plate material with a suitable thickness and are bent into a C-shaped structure in cross section. The two first wing plates 3322 are overlapped and welded with the two second wing plates 3312 respectively. In order to ensure the flatness of the outer surface of the cross beam 33, the two second wing plates 3312 can be overlapped on the outer surfaces of the two first wing plates 3322 respectively. In order to increase the strength, a reinforcing piece 35 is arranged between the first connecting beam 332 and the second connecting beam 331. The reinforcing piece 35 comprises a reinforcing plate 351 abutting against the outer side of the first web 3321 and a support plate 352. The reinforcing plate 351 is welded with the first web 3321 after abutting against the outer side of the first web 3321. The support plate 352 is perpendicular to the reinforcing plate 351. The support plate 352 and the reinforcing plate 351 can be formed by bending a plate piece. One end of the support plate 352 is connected with the reinforcing plate 351 and is arranged perpendicularly to the reinforcing plate 351. The other end of the support plate 352 is supported on the inner side of the second web 3311. The bolt 36 passes through the reinforcing plate 351, the first web 3321 and the connecting plate 32 from outside to inside. The nut 361 of the bolt 36 is pressed on the reinforcing plate 351. The nut 362 of the bolt 36 is pressed on the connecting plate 32 after being tightened. In this way, the cross beam 33 is fixed with the support 301.

[0044] The through hole 3310 is arranged on the second web 3311. The reflective sticker 34 is pasted on the outer side of the second web 3311. During installation, the reinforcing plate 351 is abutted against the inside of the first connecting beam 332. The reinforcing plate 351 is welded with the outer side of the first web 3321. The bolt passes through the first reinforcing plate 351, the first web 3321 and the connecting plate 32. The nut 362 is sleeved on the bolt 36 and is tightened. Then, the second connecting beam 331 is buckled on the first connecting beam 332. The support plate 352 is abutted against the inner side of the second connecting beam 331. The support plate 352 can be used to position the second connecting beam 331 and the first connecting beam 332. Then, the second wing plate 3312 and the first wing plate 3322 are welded and fixed. Finally, the reflective sticker 34 is pasted on the outer surface of the second web 3311. The through hole 3310 is covered with the reflective sticker 34 to shield the bolt 36. In this way, the outer surface of the cross beam 33 is flat. When the cross beam 33 needs to be disassembled, the reflective sticker 34 is torn open. The bolt 36 can be loosened by using a tool to pass through the through hole 3310. Then, the cross beam 33 is disassembled from the support 301.

[0045] The upper surface of the cross beam 33 is provided with a plurality of anti-skid bosses 3313. The anti-skid bosses 3313 on the cross beam 33 can be arranged on the upper surface of the second wing plate 3312 above the second connecting beam 331.
