The beam body includes a middle section fixed between the two front anti-collision guardrail positive installation beams and two side sections located on both sides. The front anti-collision guardrail positive installation beam is made of high-strength steel plate to rebound the energy of the impacting vehicle. Compared with the original energy-absorbing box, the front anti-collision guardrail positive installation beam here is made of high-strength steel plate. Compared with the original energy-absorbing box, the energy is directly rebounded here without energy absorption.

Description

Technical Field

[0001] The present invention relates to the field of front anti-collision beam assemblies, and particularly to a rigid front anti-collision beam assembly and a vehicle. Background Art

[0002] An anti-riot interception vehicle is a new type of comprehensive interception special equipment with high mobility, high protection, high reliability, and good man-machine environment. It is mainly used in duty security tasks to efficiently intercept and quickly dispose of ramming vehicles to eliminate security threats. A front anti-collision guardrail is provided at the front end of the vehicle and is installed on the front anti-collision beam in the vehicle body structure. At present, after the front anti-collision beam is impacted, it will transmit the impact to the energy absorption box at the rear, and the energy absorption box absorbs the energy to slow down the impact. As Figure 1 shown, the front anti-collision beam 1 is connected to the energy absorption box 2, and the energy absorption box 2 is installed through the front anti-collision beam mounting plate 3. An arc-shaped corrugated protrusion is provided on one side of the energy absorption box 2 for buffering and energy absorption. However, the disadvantage of this is that the energy of the ramming vehicle is absorbed and cannot be rebounded, which easily causes injuries to the personnel in the vehicle itself. Therefore, how to transfer the collision energy to the ramming vehicle when being impacted to reduce the impact damage to itself during the interception collision is an urgent problem to be solved by those skilled in the art. Summary of the Invention

The beam body includes a middle section fixed between the two front anti-collision guardrail positive mounting beams and two side sections on both sides. The front anti-collision guardrail positive mounting beam is made of high-strength steel plate to rebound the energy of the ramming vehicle. Compared with the original energy absorption box, the front anti-collision guardrail positive mounting beam here is made of high-strength steel plate, and directly rebounds the energy instead of absorbing it.

[0005] Optionally, a front anti-collision guardrail side mounting beam for connecting the front protection guardrail is further fixed at one end of the front anti-collision guardrail positive mounting beam close to the engine compartment, and a strengthening mechanism is further provided between the front anti-collision guardrail side mounting beam and the side section. The strengthening mechanism can increase the stability of the side section and has stronger impact resistance.

[0006] Optionally, the strengthening mechanism includes a connecting beam fixed between the front anti-collision guardrail side mounting beam and the side section, and a rigid frame is formed among the connecting beam, the front anti-collision guardrail side mounting beam, the side section, and the front anti-collision guardrail positive mounting beam to achieve support and strengthening.

[0007] Optionally, the side section, the connecting beam, and the front anti-collision guardrail side mounting beam are welded and connected. It is stronger.

[0008] Optionally, a projection welding nut is fixed at the end of the side mounting beam of the front anti-collision guardrail to facilitate connection with the front anti-collision guardrail. Utilizing the original vehicle body structure, the installation is convenient.

[0009] Optionally, a nut plate is fixed on the side mounting beam of the front anti-collision guardrail, and a reinforcing plate is correspondingly fixed on the front longitudinal beam of the engine compartment. The nut plate and the reinforcing plate are connected by bolts. This increases the connection stability.

[0010] Optionally, a projection welding bolt is provided at one end of the front mounting beam of the front anti-collision guardrail close to the front anti-collision beam guardrail to facilitate connection with the front anti-collision beam guardrail. It can be installed using the original vehicle body structure, and the installation is convenient.

[0011] Optionally, a mounting plate for convenient installation is fixed at one end of the front mounting beam of the front anti-collision guardrail close to the engine compartment. It can be used for installation on the front anti-collision guardrail, and the installation is convenient.

[0012] Optionally, the front mounting beam, the middle section, and the side section of the front anti-collision guardrail are connected by welding. It is more robust.

[0013] One of the above technical solutions has the following advantages or beneficial effects:

[0014] 1. The front mounting beam of the front anti-collision guardrail that supports the beam body is made of high-strength steel plate, replacing the original energy-absorbing box to achieve rigid support.
