Preferably, the back of the bracket is fixedly provided with a reinforcing rib, and the bottom of the reinforcing rib is fixed with the top of the mounting plate.
Structural strength between the support and the mounting plate can be improved through the reinforcing ribs, and stability and impact performance of the device are improved.
Preferably, the front surface of the arc frame is provided with an outer plate, and the outer part of the outer plate is stuck with a light reflecting strip.
The road articles can be intercepted through the outer plate, the light source can be reflected through the reflecting strips, and the warning can be carried out on a vehicle driver.
Preferably, an iron wire net is fixedly arranged between the energy absorbing components.
The device can be blocked from passing through objects through the arrangement of the wire netting, so that the device has better interception performance.
In summary, the application has the following beneficial technical effects:
When the vehicle collides with the energy absorption component, the arc frame is deformed under the stress, and the arc frame adopts an arc design, so that the kinetic potential energy of the vehicle can be fully absorbed, and the safety of passengers can be better ensured and the survival probability of the passengers in the accident vehicle can be improved by absorbing most of the kinetic energy generated during the collision.
