Technical Field
[0001] This utility model relates to the field of anti-collision vehicle frame technology, specifically to an anti-collision vehicle frame for new energy vehicles. Background Technology
[0002] With the development of modern new energy technologies, new energy vehicles have gradually been accepted by the public. In the manufacturing process of new energy vehicles, the requirements for the vehicle frame are somewhat different from those for traditional vehicle frames. Due to the special nature of new energy batteries, the vehicle frame of new energy vehicles needs to have good anti-collision performance, so as to effectively protect the new energy batteries.
[0003] Currently, the structure of car anti-collision beams in daily life is too simple. However, a simple structure may lack sufficient energy absorption capacity. In the event of a high-speed impact or a severe collision, the anti-collision beam may not be able to effectively disperse the impact energy, resulting in excessive energy being transferred to the vehicle body structure or passenger compartment, increasing the risk of injury and easily causing greater damage in an accident. To address the above problems, a new energy vehicle anti-collision frame is proposed to solve the problem. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a new energy vehicle anti-collision frame, which solves the problem that the structure of current automotive anti-collision beams is too simple. However, a simple structure may lack sufficient energy absorption capacity. In the event of a high-speed impact or a severe collision, the anti-collision beam may not be able to effectively disperse the impact energy, resulting in excessive energy being transferred to the vehicle body structure or passenger compartment, increasing the risk of injury, and easily causing significant damage in the event of an accident.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a new energy vehicle anti-collision frame, comprising two longitudinal beams arranged in parallel front to back, two third crossbeams fixedly connected to the left and right sides between the two longitudinal beams, an anti-collision component fixedly installed on the right side between the two longitudinal beams, a fixing plate fixedly connected to the left end of each of the two longitudinal beams, a first energy-absorbing box fixedly connected to the upper left side of each of the two fixing plates, a second energy-absorbing box fixedly connected to the lower left side of each of the two fixing plates, an anti-collision beam fixedly connected between the two first energy-absorbing boxes, and an anti-collision post fixedly connected between the two second energy-absorbing boxes.
[0006] Preferably, two first crossbeams are fixedly connected at the middle between the two longitudinal beams, a cross beam is fixedly connected between the two first crossbeams, and second crossbeams are fixedly connected at the inclined positions on both the left and right sides between the two longitudinal beams.
[0007] Preferably, a first reinforcing rib is fixedly connected between the fixing plate and the longitudinal beam, and a second reinforcing rib is fixedly connected between the third crossbeam on the right side and the longitudinal beam.
[0008] Preferably, the anti-collision component includes a mounting plate, which is fixedly connected to the right side of the third crossbeam on the right side, and an energy-absorbing component is fixedly connected to the middle of the right side of the mounting plate.
[0009] Preferably, the right side of the mounting plate is fixedly connected to the upper and lower sides of the energy-absorbing component with support rods. There are four support rods, all of which are bent symmetrically inward with the center line of the energy-absorbing component as the axis.
[0010] Preferably, a connecting plate is fixedly connected to the right side of the four support rods, a crash plate is fixedly connected to the right side of the connecting plate, and at least five sets of damping springs are fixedly connected between the crash plate and the connecting plate.
[0011] Preferably, guide posts are fixedly connected to both the front and rear ends of the left side of the connecting plate, and the ends of the two guide posts extend into the interior of the two longitudinal beams, and the guide posts are slidably connected to the longitudinal beams.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. This utility model effectively absorbs collision energy by setting up multiple energy-absorbing structures, such as the first energy-absorbing box, the second energy-absorbing box, and the energy-absorbing component in the anti-collision assembly. During a collision, these energy-absorbing structures can disperse energy through their own deformation, reducing the energy transferred to the vehicle body and passenger compartment, and reducing the risk of injury.
[0014] 2. This utility model forms a stable frame structure by setting longitudinal beams, transverse beams, cross beams and reinforcing ribs that are interconnected. This structure can enhance the overall strength of the vehicle frame, so that it can maintain structural integrity in the event of a collision, and better protect the occupants and the new energy battery.
[0015] 3. This utility model has a guide post on the connecting plate that is slidably connected to the longitudinal beam. This guide post can guide the movement direction of the anti-collision components during a collision, making the anti-collision process more stable and improving the anti-collision effect. The damping spring between the anti-collision plate and the connecting plate can further buffer the impact force of the collision. At the moment of collision, the damping spring consumes energy through extension and contraction, reducing the impact on the frame and the interior of the vehicle. Attached Figure Description

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0022] Reference Figure 1-3 As shown, a new energy vehicle anti-collision frame includes two parallel longitudinal beams 1 arranged front to back. Two third crossbeams 4 are fixedly connected to the left and right sides between the two longitudinal beams 1. An anti-collision component 10 is fixedly installed on the right side between the two longitudinal beams 1. A fixing plate 12 is fixedly connected to the left end of each of the two longitudinal beams 1. A first energy-absorbing box 7 is fixedly connected to the upper left side of each of the two fixing plates 12. A second energy-absorbing box 9 is fixedly connected to the lower left side of each of the two fixing plates 12. An anti-collision beam 8 is fixedly connected between the two first energy-absorbing boxes 7. An anti-collision post 13 is fixedly connected between the two second energy-absorbing boxes 9.
[0023] Furthermore, two first crossbeams 2 are fixedly connected in the middle between the two longitudinal beams 1, and a cross beam 5 is fixedly connected between the two first crossbeams 2. Second crossbeams 3 are fixedly connected at the inclined positions on both the left and right sides between the two longitudinal beams 1.
[0024] Furthermore, a first reinforcing rib 6 is fixedly connected between the fixing plate 12 and the longitudinal beam 1, and a second reinforcing rib 11 is fixedly connected between the right third crossbeam 4 and the longitudinal beam 1. The addition of the first reinforcing rib 6 and the second reinforcing rib 11 improves the torsional strength and bending strength of the frame. They ensure the stability of the frame when subjected to lateral impacts and reduce the possibility of frame deformation.
[0025] Furthermore, the anti-collision component 10 includes a mounting plate 1001, which is fixedly connected to the right side of the third crossbeam 4 on the right side. An energy-absorbing component 1002 is fixedly connected to the middle of the right side of the mounting plate 1001. The arrangement of the anti-collision component 10, especially the energy-absorbing component 1002 and the support rod 1003 on its right side, can effectively absorb and disperse the impact force when the rear of the vehicle is hit. This design reduces the risk of frame damage and protects the safety of the occupants.
[0026] Furthermore, on the right side of the mounting plate 1001, support rods 1003 are fixedly connected to the upper and lower sides of the energy-absorbing component 1002. There are four support rods 1003, all of which are bent inward with the center line of the energy-absorbing component 1002 as the axis of symmetry. The inward bending of the support rods 1003 makes them easier to bend when subjected to a collision, thereby further absorbing the collision force and ensuring that the impact force can be more effectively transmitted to the energy-absorbing component 1002.
[0027] Furthermore, a connecting plate 1004 is fixedly connected to the right side of the four support rods 1003, and a crash plate 1005 is fixedly connected to the right side of the connecting plate 1004. At least five sets of damping springs 1006 are fixedly connected between the crash plate 1005 and the connecting plate 1004. The damping springs 1006 provide additional buffering between the crash plate 1005 and the connecting plate 1004. They dissipate energy through expansion and contraction deformation, further reducing the impact force transmitted to the frame and improving the crashworthiness of the frame.
[0028] Furthermore, guide posts 1007 are fixedly connected to both the front and rear ends of the left side of the connecting plate 1004. The ends of the two guide posts 1007 extend into the interior of the two longitudinal beams 1, and the guide posts 1007 are slidably connected to the longitudinal beams 1. The cooperative design of the guide posts 1007 and the connecting plate 1004 enables the anti-collision plate 1005 to move along a predetermined path when it is hit. This design not only improves the flexibility of the frame, but also ensures the stability and reliability of the anti-collision component 10 during the collision process.
[0029] Working Principle: When a collision occurs in front of the new energy vehicle, the anti-collision beam 8 and anti-collision post 13 directly bear part of the impact force. Simultaneously, the first energy-absorbing box 7 and the second energy-absorbing box 9 begin to function, absorbing the energy generated by the impact through their own deformation. When the new energy vehicle is rear-ended, the impact force acts on the anti-collision plate 1005, which transmits the force to the connecting plate 1004. The connecting plate 1004 slides along the longitudinal beam 1 via the guide post 1007, ensuring stable movement. At this time, the energy-absorbing component 1002 begins to absorb energy, reducing the impact force transmitted to the frame. The damping spring 1006 acts as a buffer between the anti-collision plate 1005 and the connecting plate 1004, further dissipating energy through its expansion and contraction deformation. The entire frame structure, including the longitudinal beam 1, cross beams, cross beams 5, and reinforcing ribs, works together to disperse the impact force throughout the frame, enhancing its impact resistance and effectively protecting the new energy battery and the safety of the occupants.
