The support resistance members are in an isosceles trapezoidal structure. The inclined section on one side of the support resistance member is fixedly connected to the rear end face of the anti-collision beam body, and the inclined section on the other side is fixedly connected to the side wall of the connecting column.

The buffer shell cooperates with the anti-collision beam body to form a double-layer protection. The buffer shell is first subjected to external impact and collapses to the buffer space to absorb and release part of the impact force. When it is transmitted to the connecting piece, the connecting piece with a U-shaped structure is deformed again, and the two ends of the opening are close to each other, and the impact force is released and absorbed again, and then transmitted to the anti-collision beam body for resistance, and finally transmitted to the connecting column.

The edges at both ends of the anti-collision beam body are not easily deformed and bent under impact, forming effective protection in offset collisions. They cooperate with each other to make the anti-collision performance of the front-end anti-collision assembly better, and can form effective protection for occupants and vehicles in front-end collisions.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Reference Figure 1-3 As shown, the front-end anti-collision assembly of the automobile includes an anti-collision beam main body 1, and two connecting columns 2 symmetrically arranged on the rear end face of the anti-collision beam main body 1. The two connecting columns 2 are perpendicular to the anti-collision beam main body 1. A buffer shell 3 is provided at the front end of the anti-collision beam main body 1 to surround the front end face of the anti-collision beam main body 1. The two ends inside the buffer shell 3 are fixedly connected to the two ends of the outer wall of the anti-collision beam main body 1 by bolts. A buffer space 301 is left between the inside of the buffer shell 3 and the front end face of the anti-collision beam main body 1. The buffer space 301 gives the buffer shell 3 space to collapse and deform backward to absorb and release part of the external impact force.

[0021] A plurality of connectors 4 with U-shaped cross-sections are symmetrically arranged inside the buffer space 301. The two horizontal sections of the connector 4 are fixedly connected to the rear end face of the buffer shell 3 and the front end face of the anti-collision beam body 1 respectively. The connector 4 has a U-shaped structure. When the buffer shell 3 is impacted and collapses backward, the connector 4 forms a support and resistance. When the impact force is large, the open ends of the connector 4 approach each other to produce deformation, and absorb and release part of the external impact force again, and then transmit it to the anti-collision beam body 1 for resistance and interception, and finally transmit it to the connecting column 2. It can release the external impact force layer by layer multiple times, so that its protective performance is better, and effectively reduce the damage to the occupants and the vehicle.

[0022] The supporting resistance members 5 are symmetrically arranged on both sides of the connection between the connecting column 2 and the anti-collision beam body 1. The supporting resistance members 5 are in an isosceles trapezoidal structure. The inclined section on one side of the supporting resistance member 5 is fixedly connected to the rear end face of the anti-collision beam body 1, and the inclined section on the other side is fixedly connected to the side wall of the connecting column 2. The horizontally arranged long and short sides of the supporting resistance member 5 form a triangular stable structure with the anti-collision beam body 1 and the connecting column 2. The interior of the supporting resistance member 5 is also a hollow structure. The supporting resistance member 5 makes the connection structure between the connecting column 2 and the anti-collision beam body 1 more stable, and the hollow The structure makes it more lightweight. The connecting column 2 is located at the edges of both sides of the rear end surface of the anti-collision beam main body 1. The triangular stable structure formed by the supporting resistance member 5, the connecting column 2 and the anti-collision beam main body 1, when the anti-collision beam main body 1 produces an offset collision, the supporting resistance member 5 forms a supporting resistance on the edges on both sides of the anti-collision beam main body 1, reduces the degree of backward bending on both sides of the anti-collision beam main body 1, and increases its protective performance during offset collision. Their mutual cooperation makes the anti-collision performance of the front-end anti-collision assembly better, and can effectively protect the occupants and the vehicle in a front-end collision.

[0023] The interior of the anti-collision beam main body 1 is a hollow structure, and a reinforcing component connected to the front end face and the rear end face of the anti-collision beam main body 1 is provided inside the anti-collision beam main body 1. While making the anti-collision beam main body 1 lightweight, its structural strength is improved and its ability to resist deformation is improved to effectively intercept and resist external impacts.

[0024] The connecting column 2 is a hollow structure, and collapse holes 201 are symmetrically arranged on the connecting column 2. The collapse holes 201 provide the connecting column 2 with the performance of collapsing backward to absorb and release external impact again.

The middle of both ends of the upper regular hexagonal reinforcement plate 602 is provided with a second horizontal connecting plate 605 connected to the inner wall of the anti-collision beam main body 1. The lower regular hexagonal reinforcement plate 603 is arranged at the bottom of the circular reinforcement plate 601, and the bottom end of the lower regular hexagonal reinforcement plate 603 is connected to the bottom end of the interior of the anti-collision beam main body 1. A third horizontal connecting plate 606 connected to the inner wall of the anti-collision beam main body 1 is provided in the middle of both ends of the strong plate 603. Through the cooperation of the circular reinforcing plate 601, the upper regular hexagonal reinforcing plate 602, the lower regular hexagonal reinforcing plate 603, the first horizontal connecting plate 604, the second horizontal connecting plate 605, and the third horizontal connecting plate 606, a support is formed between the front end face and the rear end face of the anti-collision beam main body 1, thereby increasing the structural strength and rigidity of the anti-collision beam main body 1 and increasing its anti-deformation performance during impact. The external impact force can be dispersed to various places through the circular reinforcing plate 601, the upper regular hexagonal reinforcing plate 602, the lower regular hexagonal reinforcing plate 603, the first horizontal connecting plate 604, the second horizontal connecting plate 605, and the third horizontal connecting plate 606 for resistance and support, thereby improving the protection performance of the anti-collision beam main body 1.
