Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile accessories, in particular to a lightweight anti-collision beam. Background Art
[0002] The anti-collision beam of a car is a device used to reduce the impact energy when the vehicle is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage to the longitudinal beam of the vehicle body caused by the impact force. In this way, it plays a protective role for the vehicle. However, even a low-speed collision can cause damage to the main beam. After the main beam is damaged, it needs to be replaced or repaired, and the repair cost is relatively high. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to address the deficiencies of the above-mentioned prior art.
[0004] Provides a lightweight anti-collision beam to avoid damage to the main beam caused by low-speed collisions and reduce maintenance costs.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a lightweight anti-collision beam, including a main beam, energy absorption boxes are provided on the same side of both ends of the main beam, and each energy absorption box is provided with a mounting plate for connecting to the vehicle body, which is characterized in that: an energy absorption layer is provided on the end face of the main beam opposite to the energy absorption box, and the energy absorption layer includes a rubber jacket, and a cavity is sealed in the rubber jacket, and the cavity is filled with a shear thickening fluid.
[0006] A further configuration of the present invention is that a shaped plastic frame is provided on the outside of the rubber jacket, the rubber jacket is adhered to the inner wall of the plastic frame, so that the rubber jacket is spread along the surface of the main beam, and the plastic frame is connected to the main beam.
[0007] A further configuration of the present invention is that the plastic frame is provided with a connecting seat, threaded holes are opened through the connecting seat and at positions corresponding to the main beam, screws for connecting the main beam and the connecting seat are provided in the threaded holes, and the screws are threadedly matched with the threaded holes.
[0008] A further configuration of the present invention is that the rubber outer sleeve is deformable.
[0009] The utility model with the above characteristics: when hit, the impact force first reaches the energy absorption layer, the plastic frame is damaged, and the shear thickening fluid in the rubber jacket quickly becomes hard to digest the external force, absorb the impact force, and reduce the damage to the main beam caused by the impact. The plastic frame can be detachably connected to the main beam through the connecting seat and can be replaced after the plastic frame is damaged. The cost of replacing the plastic frame is much less than the cost of repairing the main beam.
[0010] The beneficial effects of the utility model are: reducing the damage to the main beam caused by low-speed collision and reducing maintenance costs.
[0011] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] like Figure 1 、 Figure 2 A lightweight anti-collision beam shown includes a main beam 1, and energy absorption boxes 2 are provided on the same side of both ends of the main beam 1. Each energy absorption box 2 is provided with a mounting plate 3 for connecting to the vehicle body. An energy absorption layer 4 is provided on the end face of the main beam 1 opposite to the energy absorption box 2. The energy absorption layer 4 includes a rubber jacket, and a cavity is sealed in the rubber jacket, and the cavity is filled with a shear thickening fluid. A shaped plastic frame 5 is provided on the outside of the rubber jacket, and the rubber jacket is adhered to the inner wall of the plastic frame 5 so that the rubber jacket is spread along the surface of the main beam 1. The plastic frame 5 is connected to the main beam 1, and the plastic frame 5 is provided with a connecting seat 6. Threaded holes 7 are opened through the connecting seat 6 and the corresponding positions of the main beam 1. Screws 8 for connecting the main beam 1 and the connecting seat 6 are provided in the threaded holes 7. The screws 8 are threadedly matched with the threaded holes 7, and the rubber jacket can be deformed.
[0015] When hit, the impact force first reaches the energy-absorbing layer, and the plastic frame is damaged. The shear-thickening fluid in the rubber jacket quickly becomes hard to digest the external force, absorb the impact force, and reduce the damage to the main beam caused by the impact. The plastic frame can be detachably connected to the main beam through the connecting seat and can be replaced after the plastic frame is damaged. The cost of replacing the plastic frame is much less than the cost of repairing the main beam.
