[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0028] Example 1:

[0029] like Figures 1 to 5As shown, the die-cast front-end anti-collision beam comprises an anti-collision beam body 1, energy absorption boxes 2 are respectively provided on both sides of the anti-collision beam body 1, and each energy absorption box 2 is provided with a mounting plate 3. A trailer hook threaded sleeve 4 is provided in the anti-collision beam body 1. The anti-collision beam body 1, energy absorption box 2, mounting plate 3 and trailer hook threaded sleeve 4 are integrally formed by die-casting, thereby increasing the structural strength of the anti-collision beam. In this embodiment, the anti-collision beam body 1, energy absorption box 2, mounting plate 3 and trailer hook threaded sleeve 4 are integrated into one body by die-casting, which can eliminate the steps of welding or threaded connection, saving labor costs. At the same time, it can save the need to open molds for multiple components separately, thereby saving manufacturing costs. In addition, through the die-casting integral molding method, there is no welding point between the trailer hook threaded sleeve 4 and the anti-collision beam body 1, thereby improving the rigidity and stability of the trailer hook threaded sleeve 4.

[0030] like Figure 2 and Figure 3 As shown, the mounting plate 3 is disposed on a side away from the anti-collision beam body 1, that is, the mounting plate 3 is disposed on the side close to the vehicle body. Mounting plates 3 are respectively disposed at the upper and lower ends of the energy absorption box 2, and both the upper and lower mounting plates 3 are bent toward the side away from the energy absorption box 2. Mounting holes that mate with the vehicle body are formed on the mounting plates 3. During use, the anti-collision beam body 1 can be mounted to the front end of the vehicle body via the mounting plates 3 on the anti-collision beam body 1. During installation, bolts are passed through the mounting holes, and the mounting plates 3 are threadedly connected to the front end of the vehicle body via the bolts.

[0031] The interior of the trailer hook threaded sleeve 4 is provided with threads for cooperating with the trailer hook, that is, this embodiment does not require the addition of rivet nuts, which greatly improves the accuracy of the installation point.

[0032] In this embodiment, the anti-collision beam body 1 includes an upper connecting plate 6 and a lower connecting plate 7. A longitudinal connecting plate 13 is provided between the front and middle portions of the upper and lower connecting plates 6 and 7. The energy absorption box 2 includes a box body, which is composed of two longitudinal plates, an upper connecting plate 6 and a lower connecting plate 7. The upper and lower ends of the longitudinal plates are fixedly connected to the upper and lower connecting plates 6 and 7, respectively. A partition plate 9 is fixedly connected near the middle between the two longitudinal plates. The partition plate 9 is arranged vertically, and a plurality of transversely arranged transverse plates 8 are fixedly connected between the longitudinal plate near the side of the longitudinal connecting plate 13 and the partition plate 9. This allows the energy absorption effect and effective length of the energy absorption box 2 to be increased under the same layout environment, thereby absorbing more energy.

[0033] During processing, the upper connecting plate 6, lower connecting plate 7, longitudinal connecting plate 13, longitudinal plate, partition plate 9, and transverse plate 8 are integrally formed through die-casting, significantly improving product integration and eliminating the need for welding, saving manufacturing costs. Furthermore, the integrated manufacturing process allows for better control of product dimensions, allowing for adjustment as needed, resulting in greater flexibility. The effective length of the crash box 2 in this embodiment can reach up to 222 mm, compared to only 180 mm for conventional crash boxes.

[0034] like Figure 4 and Figure 5 As shown, the outer sides of the two energy absorption boxes 2, that is, the side away from the longitudinal connecting plate 13, are provided with a SOB guide support structure 10. The front end of the SOB guide support structure 10 is provided with a curved surface 11. The upper and lower side surfaces of the SOB guide support structure 10 are respectively the upper connecting plate 6 and the lower connecting plate 7, that is, the outer upper connecting plate 6 and the lower connecting plate 7 and the curved surface 11 constitute the SOB guide support structure 10. The SOB guide support structure 10 and the anti-collision beam body 1 are integrally formed by die-casting. The upper and lower sides of the SOB guide support structure 10 are respectively provided with collapse holes 12. The collapse holes 12 ensure the effective crushing of the part where the energy absorption box 2 is located.

[0035] like Figure 2 As shown, a plurality of reinforcing ribs 5 are provided between the longitudinal connecting plate 13 and the upper connecting plate 6 and the lower connecting plate 7. The reinforcing ribs 5 are distributed in a triangular structure between adjacent reinforcing ribs 5 and between the reinforcing ribs 5 and the upper connecting plate 6 or the lower connecting plate 7. The reinforcing ribs 5 distributed in a triangular structure increase the strength and stability of the anti-collision beam body 1.

[0036] like Figure 5 As shown, the SOB guide support structure 10 is equipped with a reinforcement mechanism comprising a reinforcement sleeve 14, one end of which is fixedly connected to the curved surface 11. A plurality of evenly distributed reinforcement ribs 15 are fixedly connected to the outer circumference of the reinforcement sleeve 14. The reinforcement ribs 15 are fixedly connected to the curved surface 11 and the inner end surfaces of the upper connecting plate 6 on the upper side or the lower connecting plate 7 on the lower side of the SOB guide support structure 10. This reinforcement mechanism increases the support strength of the SOB guide support structure 10 and effectively enhances the vehicle's ability to slide out in the Y direction perpendicular to the vehicle's forward direction under SOB (offset collision) conditions.

[0037] Example 2:

[0038] A die-cast front-end anti-collision beam, the reinforcement mechanism includes a plurality of reinforcing ribs 15, the front ends of the reinforcing ribs 15 are fixedly connected to the arcuate surface 11, and the adjacent reinforcing ribs 15 and the reinforcing ribs 15 are fixedly connected to the upper or lower end surface of the anti-collision beam body 1 in a triangular structure; the rest is the same as the first embodiment.

[0039] The fixing method of the triangular structure is more secure, thereby greatly improving the support strength of the SOB guide support structure 10 .

[0040] The utility model adopts an integrated structure instead of a traditional split structure, which improves the integration of the product, eliminates the need for welding, simplifies the processing technology, saves manufacturing costs, and at the same time, can better control the product size and greatly improve flexibility.

[0041] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
