Description

Technical Field

[0001] This utility model relates to the field of automotive anti-collision beam technology, specifically an anti-collision beam for new energy vehicles. Background Technology

[0002] In the manufacturing and use of automobiles, the anti-collision beam is an essential part. When a car is involved in a traffic accident and there is a strong impact, the anti-collision beam can absorb most of the impact force and avoid transmitting the impact force to the car as much as possible. However, in the past, due to unreasonable structural design of the anti-collision beam itself, the anti-collision beam was deformed when it was impacted, which affected the deformation of the car itself.

[0003] Document CN 220947903 U discloses a reinforced automotive anti-collision beam structure, including an automotive anti-collision beam body. The main body of the anti-collision beam includes a main beam, mounting holes, and fixing blocks. The fixing blocks are welded and fixed to both ends of the inner surface of the main beam, and the mounting holes are opened inside the fixing blocks. The fixing mechanism is strengthened through design. With this structure, when the anti-collision strip is impacted, it cannot gradually weaken and reduce the impact force from the anti-collision strip itself, and easily transmits the impact force to the vehicle.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses a new energy vehicle anti-collision beam. When the anti-collision strip body is subjected to an impact force, the guide reinforcing ribs diffuse the impact force outwards, gradually weakening the impact force. The reinforcing plate can rebound against the side wall, preventing the anti-collision beam from deforming.

[0006] The technical solution of this utility model is as follows: a new energy vehicle anti-collision beam, including an anti-collision beam body, energy-absorbing boxes on both sides of the anti-collision beam body, a connecting plate at the bottom of the energy-absorbing boxes, a cavity inside the anti-collision beam body, and guide reinforcing ribs arranged at intervals on the outer surface of the anti-collision beam body. The guide reinforcing ribs are generally wavy and there are trapezoidal intervals between the guide reinforcing ribs. The anti-collision beam body is connected by a fixing structure and a connecting plate.

[0007] By adopting the above technical solution, when the car anti-collision beam is hit, the impact energy is transferred to the energy absorption box through the guide reinforcing ribs, reducing the impact force and avoiding damage to the car.

[0008] Preferably, the anti-collision beam body includes a front beam and a rear beam, with a cavity located between the front beam and the rear beam, and the ends of the front beam and the rear beam are integrally formed by welding.

[0009] By adopting the above technical solution, the cavity between the front beam and the rear beam helps to mitigate the impact force and reduce the possibility of deformation when the anti-collision beam body is hit.

[0010] Preferably, the wave-shaped guide ribs on the surface of the anti-collision beam are parallel to each other, and the guide ribs include the rib body and the sidewall located on the front beam.

[0011] By adopting the above technical solution, the guide stiffeners are parallel to each other. When the anti-collision beam is hit, the guide stiffeners can alleviate the impact force on the same surface and transfer the impact force from the stiffener body to the side wall.

[0012] Preferably, the reinforcing rib body is parallel to the rear beam, the side walls on both sides of the reinforcing rib body are inclined inward, the reinforcing rib body and the side walls are trapezoidal, and the connecting plate between the side walls is an inverted trapezoidal shape opposite to the trapezoidal shape.

[0013] By adopting the above technical solution, when the reinforcing rib body is subjected to impact force, the impact force is transmitted to the side wall, and the end of the side wall contracts inward. During the contraction, since adjacent reinforcing rib bodies share a connecting plate, the reinforcing rib bodies restrain each other, reducing the degree of inward deformation of the side wall.

[0014] Preferably, a reinforcing plate is provided at the turning point between the reinforcing rib body and the side wall, and the reinforcing plates on both sides of the reinforcing rib body are arranged opposite each other, with the reinforcing plates being arc-shaped.

[0015] By adopting the above technical solution, when the sidewalls deform inward, the contact between the reinforcing plates can have an outward rebound force, which allows the deformation of the sidewalls to recover quickly and alleviates the impact force.

[0016] Preferably, the reinforcing plates are arranged in opposite arcs, and the length of the reinforcing plates is less than the maximum deformation strength of the reinforcing rib body and the distance between the sidewall and the connecting plate, and the guide reinforcing rib and the reinforcing plate do not contact each other.

[0017] By adopting the above technical solution, when the reinforcing rib body is impacted, the sidewall retracts inward and the reinforcing rib body contracts inward. The reinforcing rib body does not contact the reinforcing plate, which allows the reinforcing plates to contact each other, causing the sidewall to rebound outward.

[0018] Preferably, the top of the energy-absorbing box is connected to the anti-collision beam body through a fixing structure. The fixing structure includes a fixing rod located at the top of the energy-absorbing box, and the end of the fixing rod is provided with a limiting end. The fixing rod is fixed by a limiting plate and the upper surface of the anti-collision beam body.

[0019] By adopting the above technical solution, the energy-absorbing box is fixed on the anti-collision beam body. When the anti-collision beam body is impacted, the impact force is absorbed into the energy-absorbing box, thus preventing the anti-collision beam from deforming.

[0020] Preferably, the reinforcing rib body, side wall, connecting plate, and reinforcing plate are integrally formed.

[0021] By adopting the above technical solutions, the overall strength of the anti-collision beam body is enhanced.

[0022] The advantages of this utility model are as follows: 1. By forming a trapezoid between the reinforcing rib body and the side wall, when the reinforcing rib body is impacted, the oblique side wall can exert an outward force on the reinforcing rib body, offsetting part of the impact force and reducing the possibility of deformation of the anti-collision beam.

[0023] 2. This utility model provides a reinforcing plate between the side wall and the connecting plate. When the reinforcing rib body is impacted, the reinforcing plate is in a relative arc shape and the reinforcing plates are in contact with each other, which can increase the outward elastic force, so that when the reinforcing plate is outward, the side wall can rebound outward as quickly as possible.

[0024] 3. When the present invention is impacted, the anti-collision beam body can transfer the impact force to the reinforcing rib body. The wave-shaped shape can increase the path length of the impact force transmission, disperse the impact force, reduce the impact force to the minimum as much as possible, and avoid deformation of the anti-collision beam.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-4As shown, the new energy vehicle anti-collision beam includes an anti-collision beam body 1, energy-absorbing boxes 8 on both sides of the anti-collision beam body 1, a connecting plate 9 at the bottom of the energy-absorbing box 8, a cavity 7 inside the anti-collision beam body 1, and guide reinforcing ribs 2 arranged at intervals on the outer surface of the anti-collision beam body 1. The guide reinforcing ribs 2 are generally wavy and have trapezoidal intervals between them. The anti-collision beam body 1 is connected to the connecting plate 203 through a fixing structure. When the vehicle anti-collision beam is hit, the impact energy is transferred to the energy-absorbing box 8 through the guide reinforcing ribs 2, reducing the impact force and avoiding damage to the vehicle.

[0032] The anti-collision beam body 1 includes a front beam 5 and a rear beam 6. A cavity 7 is located between the front beam 5 and the rear beam 6. The ends of the front beam 5 and the rear beam 6 are integrally formed by welding. The cavity 7 between the front beam 5 and the rear beam 6 helps to mitigate the impact force and reduce the possibility of deformation when the anti-collision beam body 1 is impacted.

[0033] The wave-shaped guide ribs 2 on the surface of the anti-collision beam body 1 are parallel to each other. The guide rib 201 includes the rib body 201 and the side wall located on the front beam 5. The guide ribs 2 are parallel to each other. When the anti-collision beam is hit, the guide ribs 2 can alleviate the impact force on the same surface and transfer the impact force from the rib body 201 to the side wall.

[0034] The reinforcing rib body 201 is parallel to the rear beam 6. The side walls 202 on both sides of the reinforcing rib body 201 are inclined inward. The reinforcing rib body 201 and the side walls 202 are trapezoidal. The connecting plate 203 between the side walls 202 is an inverted trapezoidal shape opposite to the trapezoidal shape. When the reinforcing rib body 201 is subjected to an impact force, the impact force is transmitted to the side wall. The end of the side wall 202 contracts inward. When it contracts, since the adjacent reinforcing rib bodies 201 share a connecting plate 203, the reinforcing rib bodies 201 restrain each other, reducing the degree of inward deformation of the side wall 202.

[0035] A reinforcing plate 4 is provided at the turning point between the reinforcing rib body 201 and the side wall 202. The reinforcing plates 4 on both sides of the reinforcing rib body 201 are arranged opposite each other. The reinforcing plates 4 are arc-shaped. When the side wall 202 deforms inward, the reinforcing plates 4 can have an outward rebound force when they come into contact with each other, so that the deformation of the side wall 202 can be quickly restored and the impact force can be relieved.

[0036] The reinforcing plates 4 are arranged in an arc shape relative to each other, and the length of the reinforcing plates 4 is less than the maximum deformation strength of the reinforcing rib body 201 and the distance between the side wall 202 and the connecting plate 203. The guide reinforcing rib 201 and the reinforcing plates 4 do not contact each other. When the reinforcing rib body 201 is impacted, the side wall 202 retracts inward and the reinforcing rib body 201 contracts inward. The reinforcing rib body 201 does not contact the reinforcing plates 4, which allows the reinforcing plates 4 to contact each other, causing the side wall 202 to rebound outward.

[0037] The top of the energy-absorbing box 8 is connected to the anti-collision beam body 1 through a fixing structure. The fixing structure includes a fixing rod 10 located at the top of the energy-absorbing box 8. The end of the fixing rod 10 is provided with a limiting end 11. The fixing rod 10 is fixed to the upper surface of the anti-collision beam body 1 through a limiting plate 12. The energy-absorbing box 8 is fixed on the anti-collision beam body. When the anti-collision beam body 1 is impacted, the impact force is absorbed into the energy-absorbing box to prevent the anti-collision beam from deforming.

[0038] The reinforcing rib body 201, side wall 202, connecting plate 203, and reinforcing plate 4 are integrally formed to enhance the overall strength of the anti-collision beam body 1.

[0039] When the anti-collision beam is impacted, the anti-collision beam body 1 is the first to be impacted. The wave-shaped guide stiffener 2 can increase the propagation path of the impact force. When the impact force is propagated radially, it can weaken the impact force. When the stiffener body 201 is impacted, the side wall 202 moves inward. At the same time, the impact between the stiffener plates 4 on the side wall 202 can cause the inward side wall 202 to rebound outward, reducing the deformation caused by the impact. The remaining impact force is transmitted to the energy absorption box 8.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
