[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Reference Figure 1-4As shown, the impact-resistant front-end collision protection assembly for automobiles includes a collision beam body 1 and connecting arms 2 symmetrically arranged on both sides of the rear end face of the collision beam body 1. The connecting arms 2 have crumple zones 201. The connecting arms 2 are fixed to the vehicle by bolts, and are welded to the collision beam body 1. The crumple zones 201 guide the crumple direction of the connecting arms 2, causing the collision beam body 1 and connecting arms 2 to crumple rearward during a collision to absorb and mitigate external impact forces. A collision box 3 is symmetrically arranged on the front end face of the collision beam body 1, and the two ends of the rear end face of the collision box 3 are symmetrically arranged with tops of the collision beam body 1. The connecting part 301 is fixedly connected to the end and the bottom. The connecting part 301 is detachably connected to the anti-collision beam body 1 by bolts. The anti-collision box 3 first resists and absorbs the external impact, and then transmits it to the anti-collision beam body 1 to resist and absorb the external impact, so as to improve its impact resistance performance. In low-speed collisions, the anti-collision box 3 can resist without affecting the anti-collision beam body 1. Only the anti-collision box 3 needs to be replaced. Vertical plates 302 are horizontally arranged between the inner walls on both sides of the anti-collision box 3. The vertical plates 302 increase the structural strength and stability of the two side walls of the anti-collision box 3, improve the deformation resistance of the anti-collision box 3, and enhance its protective performance.

[0020] A reinforcing plate 4 is provided between the two connecting arms 2, behind the collapse hole 201. The reinforcing plate 4 improves the overall integrity between the two connecting arms 2 and makes the structure more stable. A support energy-absorbing component is provided between the front end face of the reinforcing plate 4 and the rear end face of the anti-collision beam body 1. The support energy-absorbing component includes a first support plate 501, a second support plate 502, a third support plate 503, a fourth support plate 504, and a support column 505. The first support plate 501, the second support plate 502, the third support plate 503, and the fourth support plate 504 have a circular cross-section. The first support plate 501, the second support plate 502, the third support plate 503, and the fourth support plate 504 are located on the same central axis. The support column 505 is arranged in a ring around the adjacent first support plate 501, the second support plate 502, the third support plate 503, and the fourth support plate 504. Between 504, at least one crumple zone 506 is annularly formed on the outer surface of the support column 505 to support the energy-absorbing component and the reinforcing plate, further increasing the structural stability and impact resistance of the anti-collision beam body 1. When an external impact is transmitted to the anti-collision beam body 1, it is resisted and supported by the energy-absorbing component and the reinforcing plate. When the anti-collision beam body 1 collapses backward, the impact force is sequentially transmitted to the first support plate 501, the second support plate 502, the third support plate 503, the fourth support plate 504 and its adjacent support column 505. The support column 505 resists and absorbs the impact force layer by layer through the crumple zone 506, so that the external impact is weakened layer by layer. They work together to effectively mitigate the external impact, making the front anti-collision assembly more impact-resistant and protective, and effectively protecting the safety of the occupants in a frontal collision.

[0021] Preferably, the first support plate 501 is fixedly connected to the rear end face of the anti-collision beam body 1, the fourth support plate 504 is fixedly connected to the front end face of the reinforcing plate 4, the second support plate 502 is located behind the first support plate 501, the third support plate 503 is located in front of the fourth support plate 504, and the first support plate 501 and the fourth support plate 504 are fixedly connected to the anti-collision beam body 1 and the reinforcing plate 4 by bolts.

[0022] Preferably, a buffer device is provided between the anti-collision beam body 1 and the reinforcing plate 4, inside the first support plate 501, second support plate 502, third support plate 503, and fourth support plate 504.

The buffer device is located inside them and is on the same central axis. One end of the buffer device is fixedly connected to the rear end face of the anti-collision beam body 1, and the other end is fixedly connected to the reinforcing plate 4. When the anti-collision beam body 1 collapses backward, it works together with the energy-absorbing support components to mitigate and absorb external impact forces. The locking device limits the rebound of the buffer device.

[0023] Preferably, the buffer device includes a pressure block 601, a guide rod 602, a guide cylinder 603, and a buffer spring 604. The pressure block 601 is fixedly connected to the rear end face of the anti-collision beam body 1, and the guide cylinder 603 is fixedly connected to the front end face of the reinforcing plate 4. One end of the guide rod 602 is fixedly connected to the rear end face of the pressure block 601, and the other end extends into the guide cylinder 603 and can slide inside the guide cylinder 603. The buffer spring 604 is sleeved on the guide rod 602 outside the guide cylinder 603. One end of the buffer spring 604 abuts against the pressure block 601, and the other end abuts against the front end face of the guide cylinder 603. When the anti-collision beam body 1 collapses, it drives the pressure block 601 to move towards one end of the guide cylinder 603, and drives the guide rod 602 to slide into the guide cylinder 603. The pressure block 601 compresses the buffer spring 604 to mitigate and absorb external impact.

[0024] Preferably, the locking device includes a first mounting plate 701, a limiting plate 702, a second mounting plate 703, a sleeve 704, a locking rod 705, a slider 706, a spring 707, and a limiting block 708. The first mounting plate 701 is disposed on the rear end face of the pressure block 601. The limiting plates 702 are symmetrically disposed on both sides of the rear end face of the pressure block 601. The second mounting plates 703 are symmetrically disposed on both sides of the guide cylinder 603. The rear end face of the limiting plate 702 penetrates through the second mounting plate 703 and extends to the rear of the second mounting plate 703. The sleeve 705... 4. A locking rod 705 is movably disposed inside a sleeve 704, located on the front end face of the second mounting plate 703. The locking rod 705 extends through the sleeve 704 on both sides to the outside of the sleeve 704. A slider 706 and a spring 707 are disposed on the locking rod 705 inside the sleeve 704. The slider 706 is slidably connected to the inner wall of the sleeve 704. One end of the spring 707 abuts against the slider 706, and the other end abuts against the inner wall of the sleeve 704. A limiting plate 702 is positioned near the locking rod 705, evenly spaced from front to back. A locking groove 709, matching the locking rod 705, is provided. A limiting block 708 is located on the side of the locking rod 705 outside the sleeve 704, away from the locking groove. One side of the locking rod 705 abuts against the limiting plate 702. Simultaneously, the slider 706 compresses the spring 707, causing it to elastically deform. The locking rod 705, under the reverse force of the spring 707, abuts against the side wall of the limiting plate 702, generating a certain amount of damping. The first mounting plate 701 moves with the pressure block 601. During buffering, the limiting plate 702... One end of the guide cylinder 603 moves horizontally until the locking groove 709 corresponds to the locking rod 705. The directional force of the spring 707 drives the slider 706 and the locking rod 705 to move horizontally to one side of the locking groove 709, and the locking rod 705 enters the locking groove 709 to form a lock, thereby restricting the reset of the pressure block 601. The limiting block 708 is used for manual separation of the locking rod 705 from the locking groove 709 during later maintenance. The locking groove 709, which is designed layer by layer, can form a lock at different positions according to the magnitude of the external impact force.
