Description

Technical Field

[0001] This utility model belongs to the field of bumper technology, and in particular relates to an anti-collision bumper component for automobiles. Background Technology

[0002] Car bumpers are important safety devices installed at the front and rear of a vehicle. Their main function is to absorb and mitigate the impact of a collision, thereby protecting the vehicle body and the safety of passengers. They are usually made of plastic, metal or composite materials. In low-speed collisions, bumpers can reduce vehicle damage, while in high-speed collisions, they work in conjunction with systems such as airbags to improve overall safety.

[0003] Existing car bumpers are mainly used to protect the vehicle itself, and their buffer area is relatively small. When a pedestrian accidentally collides with the car bumper, the pedestrian will directly contact the rigid structure of the car, increasing the risk of injury to the pedestrian in traffic accidents. To address this, we propose a car anti-collision bumper component. Utility Model Content

[0004] The purpose of this invention is to provide a car bumper assembly with a buffer mechanism. Specifically, an air pump injects air into an airbag and inflates it. During the inflating process, the airbag pushes the front panel forward and moves the arc-shaped plate three forward via a square-round sliding rod. This allows the arc-shaped plate three to slide forward before a collision, increasing the buffer area between the pedestrian and the car, absorbing or dispersing the impact force on the pedestrian, and reducing the risk of pedestrian injury in traffic accidents. This solves the problem that existing car bumpers mainly protect the vehicle itself, and their buffer area is small. When a pedestrian accidentally collides with the car bumper, the pedestrian will directly contact the rigid structure of the car, increasing the risk of pedestrian injury in traffic accidents.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a car anti-collision bumper assembly, including a buffer mechanism. The buffer area for the bumper assembly includes an arc plate one, an arc plate two is installed on the front of the arc plate one, and three square and round sliding rods are provided on the front side inside the arc plate two.

[0038] A specific application of this embodiment is as follows: In use, the arc-shaped plate 111 is first installed on the bottom front of the car using bolts. When a collision is imminent, the air pump 1131 is activated, causing it to pump air into the hose and then into the airbag 1132, causing the airbag 1132 to inflate. When the airbag 1132 inflates, it pushes the front plate 115 to slide forward, causing the first rotating rod 1161 and the second rotating rod 1162 to rotate, causing their small round blocks to slide along the inner wall of the slide rail 117. Then, the damper 118 is pulled forward, and the front plate 115 is displaced forward. 5. Pushing the rectangular slide plate 121 causes it to move forward along the inner wall of the irregular slide rail 123 via the irregular slider 122, and pushes the arc plate 1192 forward via the square and round slide rod 1191, creating a larger buffer area between the colliding object and the arc plate 111, increasing the contact area with the pedestrian, thereby effectively dispersing the impact force and reducing direct injury to the pedestrian. Furthermore, the arc plate 1192 is made of high-strength composite material, which can absorb more energy during the collision to further reduce the impact on the pedestrian and prevent direct contact between the pedestrian and the rigid structure of the car.

[0039] After prolonged use, the buffer mechanism 1 should be replaced or maintained regularly to ensure its proper functioning and prevent accidental injuries due to its failure. Rotate the threaded pin 2172 to disengage the threaded connection between the threaded pins 2172. Then, move the threaded pin 2172 upwards to pull it out from inside the convex block 211 and the pin 215, releasing the lock on 2156. Next, pull the handle 221 outwards, causing it to slide along the slide rail 222 and displace the square plate 214, pulling the pin 215 out from inside the convex block 211. This releases the pin. 215 locks the convex block 211 and the insert plate 212, then moves the arc plate 212 forward to remove the insert plate 212 from the inside of the convex block 211. Next, the buffer mechanism 1 and its internal parts are evaluated to confirm whether the buffer mechanism 1 needs to be replaced or repaired. After replacement or repair, the insert plate 212 is inserted into the convex block 211, and then the handle 221 is released so that the pin 215 is inserted into the inside of the insert plate 212 under the action of the spring 216, locking the convex block 211 and the insert plate 212. Then the threaded pin 2172 is inserted into the round hole 2171 and tightened to complete the locking of the pin 215.
