Embodiment Construction
[0032] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0033] The present invention aims at the problem that the anti-collision effect of the car door anti-collision beam is not good in the prior art, and provides a car door anti-collision beam assembly, such as Figure 1 to Figure 3 shown, including:
[0034] The first U-shaped beam 1, the middle beam 2 and the second U-shaped beam 3;
[0035] The first U-shaped beam 1 includes a bottom 4 and two end portions 5, and the two end portions 5 are provided with a first flanging structure 6;
[0036] The second U-shaped beam 3 includes a bottom 7 and two end portions 8, and the two end portions 8 are provided with a second flanging structure 9;
[0037] The first U-shaped beam 1 and the second U-shaped beam 3 are fastened and connected, and are positioned and f...

The invention provides a vehicle door anti-collision beam assembly, a vehicle door and a vehicle. The vehicle door anti-collision beam assembly comprises a first U-shaped beam, an intermediate beam and a second U-shaped beam. The first U-shaped beam comprises a base and two ends, and the two ends are provided with first edge overturning structures. The second U-shaped beam comprises a base and two ends, and the two ends are provided with second edge overturning structures. The first U-shaped beam and the second U-shaped beam are in buckled connection and are fixedly positioned through the first edge overturning structures and the second edge overturning structures. The intermediate beam is placed in an accommodating space formed after the first U-shaped beam and the second U-shaped beam are buckled, and the first U-shaped beam adheres to the inner wall of the second U-shaped beam. The part of the intermediate beam in contact with the first U-shaped beam and the first U-shaped beam jointly form an anti-collision beam bearing part, and the part of the intermediate beam in contact with the second U-shaped beam and the second U-shaped beam jointly form an anti-collision beam buffering part. According to the scheme, side collision impact energy can be absorbed in a large amount, the invasion amount is effectively reduced, and the life safety of drivers and passengers are guaranteed well.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle door anti-collision beam assembly, a vehicle door and a vehicle. Background technique [0002] In the side collision accident of the vehicle, the door anti-collision beam has played a great role in protecting the occupants, so the method of increasing the thickness and strength of the door anti-collision beam has been widely used in passenger cars. [0003] However, this type of anti-collision beam is mainly to control the amount of intrusion during the collision and provide the necessary living space for the occupants. However, it lacks the control of the peak load of the collision, and there is no effective energy-absorbing structure arranged in the door, which cannot absorb The impact energy generated, the excessive initial peak load during the collision process will still cause the occupant to bear excessive acceleration, and the seat belt has limited ability to re...
