Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision beams, and more particularly to an automotive anti-collision beam structure. Background Technology

[0002] Anti-collision beams are an important component of automobiles. They mainly consist of beams and energy-absorbing boxes and are commonly used in the most prominent parts of the front and rear of a car. They can absorb energy during a collision, buffer and guide the impact force, thereby reducing the impact on the vehicle body structure, improving the safety of the engine compartment and passenger compartment, and reducing maintenance costs.

[0003] In a collision, the lateral proportion of the anti-collision beam plays a crucial role. With the improvement of vehicle safety, the lateral proportion of the anti-collision beam has gradually reached over 82%. There is an extension on the side of the energy-absorbing box, which can cope with the vehicle's offset impact. Side impacts may directly cause the beam to bend, failing to buffer the impact force in time. Side collisions may affect the front main beam of the vehicle, affecting the vehicle's safety and increasing maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automotive anti-collision beam structure to solve the problem that the anti-collision beam may bend on the side, resulting in a small absorption capacity.

[0005] Based on the technical problems existing in the background art, this utility model proposes an automotive anti-collision beam structure, including a main beam body and an energy-absorbing box. Two energy-absorbing boxes are respectively connected to the same side of both ends of the main beam body. Sub-beam bodies are provided at both ends of the main beam body. A connecting beam is connected between the sub-beam bodies and the energy-absorbing boxes to form a triangular support.

[0006] Preferably, the secondary beam and the main beam have an included angle.

[0007] Preferably, the energy-absorbing box is provided with multiple first guide slots.

[0008] Preferably, the connecting beam is provided with multiple second guide grooves.

[0009] Preferably, the cross-sections of the main beam and the secondary beam are two connected rectangular collapsible tubes, and a crescent-shaped connecting strip connects the two collapsible tubes.

[0010] Preferably, the main beam and the secondary beam are cast as a single piece.

[0011] Compared with the prior art, the automotive anti-collision beam structure proposed in this utility model adopts the above-mentioned technical solution and achieves the following technical effects:

[0012] This invention can increase the length of the anti-collision beam, thereby increasing its protection ratio for the vehicle and strengthening the protection of the vehicle's sides. This invention can also improve the compressive strength of the anti-collision beam's sides and increase the force required for the anti-collision beam to bend to the sides, thereby improving the energy absorption strength of the anti-collision beam, enhancing safety, and reducing maintenance costs.

[0016] Example

[0017] Please refer to Figures 1-2 This utility model proposes an automotive anti-collision beam structure, including a main beam 1 and energy-absorbing boxes 2. Two energy-absorbing boxes 2 are connected to the same side at both ends of the main beam 1. When a frontal or rearal collision occurs, the beam will be the first to bear the force. The beam has a certain curvature and can resist a certain deformation under pressure. At the same time, it can transmit the force to the energy-absorbing boxes 2 in a timely manner when under pressure, and the force is absorbed by the energy-absorbing boxes 2. At both ends of the main beam 1, there are secondary beams 11. The secondary beams 11 can extend the coverage of the beam and increase the coverage ratio of the beam relative to the vehicle, which can buffer offset collisions and thus protect some lights or sensors. At the same time, the secondary beams 11 and the energy-absorbing boxes 2 are connected by a connecting beam 3 to form a triangular support. The connecting beam 3 also plays the role of energy absorption and guides the force of the secondary beams 11 to the energy-absorbing boxes 2, which can improve the energy absorption strength of the secondary beams 11 and increase the energy absorption force of the entire anti-collision beam.

[0018] In specific implementation, refer to Figure 1 The sub-beam 11 has an angle with the main beam 1. On the side of the connecting beam 3 of the main beam of the car, the space is usually small. Due to the limitation of the shape of the bumper shell, its internal space is small and the curvature is large, which affects the extension of the side of the anti-collision beam. Therefore, the space is compressed by bending. At the same time, the connecting beam 3 guides and buffers, which improves the compressive strength of the sub-beam 11 and thus improves the safety performance.

[0019] In specific implementation, refer to Figure 1The energy-absorbing box 2 is provided with multiple first guide grooves 21. The energy-absorbing box 2 mainly absorbs impact force through deformation. Its guide grooves can guide the energy-absorbing box 2 to deform, while ensuring that the energy-absorbing box 2 will not break. When the energy-absorbing box 2 breaks, its energy absorption will be lost. Therefore, the deformation can be guided by setting guide grooves.

[0020] In specific implementation, refer to Figure 1 The connecting beam 3 is provided with multiple second guide grooves 31; the connecting beam 3 can improve the compressive strength of the sub-beam 11. Since the sub-beam 11 is bent at a certain angle relative to the main beam 1, it can increase the lateral protection ratio of the vehicle. However, the sub-beam 11 has poor bending resistance. The triangular support formed by the sub-beam 11 can increase the bending strength of the sub-beam 11. When the sub-beam 11 bears the force, its force will be transmitted to the connecting beam 3. The second guide grooves 31 can guide the connecting beam 3 to deform and absorb energy, and transfer the energy to the energy absorption box 2.

[0021] In specific implementation, refer to Figure 2 The main beam 1 and the secondary beam 11 have cross-sections of two connected rectangular collapsible tubes 12, and the two collapsible tubes 12 are connected by a crescent-shaped connecting strip 13. When the main beam 1 is impacted, the two collapsible tubes 12 can approach each other, and the connecting strip 13 can bend to absorb a certain amount of energy, thereby improving the compressive strength of the entire anti-collision beam.

[0022] In specific implementation, refer to Figure 1 The main beam 1 and the secondary beam 11 are cast as a single piece; this enhances the strength of the integral structure.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
