Abstract
Description
Technical Field
[0001] This utility model relates to the field of bumpers, specifically a high-strength vehicle bumper anti-collision structure. Background Technology
[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear of the vehicle. Many years ago, car bumpers were made by stamping steel plates into channel steel and riveting or welding them to the longitudinal beams of the chassis, leaving a large gap between them and the car body, which looked very unsightly. With the development of the automotive industry and the extensive use of engineering plastics in the automotive industry, car bumpers, as an important safety device, have also embarked on a path of innovation. Today's car bumpers, in addition to maintaining their original protective function, also strive for harmony and unity with the car body design and pursue lightweight design.
[0003] Chinese Patent No. CN218858349U discloses a high-strength vehicle bumper anti-collision structure. When the anti-collision beam is impacted by an external force, it will drive the second hinge seat to move towards the load-bearing beam. This will push the first hinge seat to move through the force transmission structure, causing the rectangular slider to slide on the outer edge of the positioning slide rod. This will cause the pressure spring to deform and contract under pressure. The deformation and contraction of the pressure spring can absorb and buffer the impact of the external force. After the impact of the external force disappears, the rectangular slider can be pushed back to its original position under the elastic force of the pressure spring. Thus, the anti-collision beam is reset through the first hinge seat, the force transmission structure, and the second hinge seat. This technology is reusable and has strong practicality.
[0004] However, the patent has the following defects: when converting the impact force into a lateral impact force, it only uses a single pressure spring for buffering, lacking a mechanism that can buffer the impact force both laterally and longitudinally, and lacking an elastic support component in the lateral buffering, which causes the pressure spring to only buffer the impact force once, resulting in poor buffering effect. Utility Model Content
[0005] This utility model aims to provide a high-strength vehicle bumper anti-collision structure, mainly to solve the technical problems of existing technology that lack a mechanism capable of lateral and longitudinal buffering of impact force, and lack of adding elastic support components in lateral buffering, resulting in the pressure spring only being able to buffer the impact force once, thus causing poor buffering effect.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A high-strength vehicle bumper anti-collision structure includes an anti-collision beam with a mounting groove on its front side and an outer plate on its front side. It also includes a longitudinal buffer mechanism, a support member, a lateral buffer mechanism, a rotating member, and an elastic support member. Several longitudinal buffer mechanisms are provided, slidably mounted on the rear side of the anti-collision beam, with one end of each mechanism penetrating the inner wall of the mounting groove and extending into the groove. The support member is located outside the longitudinal buffer mechanisms, and the lateral sliding mechanism is slidably mounted on the support member. The rear side of the outer plate is fixedly connected to one end of each longitudinal buffer mechanism. The rotating member is rotatably mounted between the outer plate and the lateral buffer mechanism. The elastic support member is sleeved on the outside of adjacent support members and fixedly connected between adjacent lateral buffer mechanisms.
[0008] The working principle and beneficial effects of this utility model:
[0009] 1. Working Principle: The outer panel is connected to the longitudinal buffer mechanism. When the outer panel is impacted and moves towards the front of the anti-collision beam, it causes the longitudinal buffer mechanism to stretch and move towards the rear of the anti-collision beam, thus providing longitudinal buffering of the impact force on the outer panel. At the same time, the movement of the outer panel causes the rotating parts to expand to both sides of the longitudinal buffer mechanism, which in turn causes the rotating parts to stretch the transverse buffer mechanism. Simultaneously, the transverse buffer mechanism moves on the support members, providing transverse buffering of the impact force on the outer panel. Due to the change in the position of the adjacent transverse buffer mechanisms, combined with the support of the elastic support members, the impact force on the transverse buffer mechanisms is buffered, thereby further buffering the impact force and increasing the impact resistance of the anti-collision beam and the outer panel.
[0010] 2. Beneficial effects:
[0011] (1) As described in the prior art (CN218858349U), when the anti-collision beam is impacted by an external force, it will drive the second hinge seat to move toward the load-bearing beam, thereby pushing the first hinge seat to move through the force transmission structure. This causes the rectangular slider to slide on the outer edge of the positioning slide rod, and the pressure spring to deform and contract under pressure. The deformation and contraction of the pressure spring can play an energy absorption and buffering role against the impact of the external force. After the impact of the external force disappears, the rectangular slider can be pushed back to its original position under the elastic force of the pressure spring. Thus, the anti-collision beam is reset through the first hinge seat, the force transmission structure, and the second hinge seat. This technology is conducive to repeated use and has strong practicality. However, when this prior art converts the impact force into a lateral impact force, it only... The previous method relied solely on a single compression spring for cushioning, lacking mechanisms for both lateral and longitudinal impact buffering. Furthermore, the absence of elastic supports in the lateral buffering resulted in the compression spring only providing single-stage cushioning, leading to poor buffering effectiveness. This solution utilizes a first tension spring to provide longitudinal cushioning of the outer plate upon impact. Simultaneously, a support plate causes the second tension spring to extend as the outer plate approaches the front of the anti-collision beam upon impact, thus providing lateral cushioning. The change in the position of adjacent sliders, combined with the support spring's support, further buffers the impact force on the sliders, thereby increasing the impact resistance of the anti-collision beam and outer plate.
[0012] Preferably, the longitudinal buffer mechanism includes a movable rod, a connecting plate, a first tension spring, and a connecting block. One end of the movable rod slides through the rear side of the anti-collision beam and the inner wall of the mounting groove. One end of the movable rod is fixedly connected to the connecting plate, and the other end is fixedly connected to the connecting block. A first tension spring is sleeved on the outer side of the movable rod. One end of the first tension spring is fixedly connected to the front side of the connecting plate, and the other end is fixedly connected to the rear side of the anti-collision beam. When the outer plate is impacted, the outer plate moves towards the front side of the anti-collision beam. At this time, the outer plate drives the support rod to move, the support rod drives the connecting block to move, and thus the connecting block drives the movable rod to move. In turn, the movable rod drives the connecting plate to move, and the connecting plate drives the first tension spring to stretch, so that the outer plate can be longitudinally buffered when subjected to impact force.
[0013] Preferably, it also includes support rods, one end of which is fixedly connected to one side of the connecting block, and one end of several support rods is fixedly connected to the rear side of the outer plate; through the support rods, the outer plate can be connected to the connecting block, so that when the outer plate moves, it can drive the connecting block to move.
[0014] Preferably, the support includes connecting rods and limiting plates. There are two connecting rods, one end of which is fixedly connected to both sides of the longitudinal buffer mechanism, and the other end of which is fixedly connected to the limiting plate. One end of each connecting rod is fixedly connected to both sides of the connecting block. The connecting rods can guide the transverse buffer mechanism.
[0015] Preferably, the lateral buffer mechanism includes a slider and a second tension spring. There are two sliders, which are slidably connected to the outer walls of two connecting rods. The outer walls of the connecting rods are fitted with second tension springs. One end of the second tension spring is fixedly connected to one side of the slider, and the other end is fixedly connected to the outer side of the longitudinal buffer mechanism. The other ends of the two second tension springs are fixedly connected to both sides of the connecting block. When the slider drives the second tension springs to stretch, the impact force is laterally buffered.
[0016] Preferably, the rotating component includes a connecting seat, a support plate, and a mounting seat. The rear side of the connecting seat is fixedly connected to the front side of the transverse buffer mechanism. The support plate is rotatably connected inside the connecting seat. The mounting seat is rotatably sleeved at one end of the support plate. The front side of the mounting seat is fixedly connected to the rear side of the outer plate. The rear side of the connecting seat is fixedly connected to the front side of the slider. The inner side of the outer plate drives the mounting seat to move. The mounting seat drives the support plate to move. The support plate drives the connecting seat to move. Thus, the connecting seat drives the slider to move outward on the connecting rod. At this time, the support plate expands towards the front side of the anti-collision beam between the connecting seat and the mounting seat.
[0017] Preferably, the elastic support includes a support spring, which is sleeved on the outside of an adjacent support and its two ends are respectively fixedly connected to one side of an adjacent transverse buffer mechanism. The support spring is also sleeved on the outside of an adjacent support rod and its two ends are respectively fixedly connected to one side of an adjacent slider. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-5 As shown, the system includes a crash beam 1 with a mounting groove 2 on its front side and an outer plate 8 on its front side. It also includes a longitudinal buffer mechanism, a support component, a transverse buffer mechanism, a rotating component, and an elastic support component. Several longitudinal buffer mechanisms are provided, slidably mounted on the rear side of the crash beam 1. One end of each longitudinal buffer mechanism penetrates the inner wall of the mounting groove 2 and extends into the groove. Each longitudinal buffer mechanism includes a moving rod 3, a connecting plate 4, a first tension spring 5, and a connecting block 6. One end of the moving rod 3 slidably penetrates the rear side of the crash beam 1 and the inner wall of the mounting groove 2. One end of the moving rod 3 is fixedly connected to the connecting plate 4, and the other end is fixedly connected to the connecting block. 6. A first tension spring 5 is sleeved on the outside of the movable rod 3. One end of the first tension spring 5 is fixedly connected to the front side of the connecting plate 4, and the other end is fixedly connected to the rear side of the anti-collision beam 1. It also includes a support rod 7. One end of the support rod 7 is fixedly connected to one side of the connecting block 6. Several support rods 7 are fixedly connected to the rear side of the outer plate 8. When the outer plate 8 is impacted, the outer plate 8 moves towards the front side of the anti-collision beam 1. At this time, the outer plate 8 drives the support rod 7 to move, the support rod 7 drives the connecting block 6 to move, and thus the connecting block 6 drives the movable rod 3 to move. In turn, the movable rod 3 drives the connecting plate 4 to move, and the connecting plate 4 drives the first tension spring 5 to stretch, so that the outer plate 8 can be longitudinally buffered when subjected to impact force.
[0026] The support component is located outside the longitudinal buffer mechanism. The support component includes connecting rods 9 and limiting plates 10. Two connecting rods 9 are provided, with one end fixedly connected to both sides of the longitudinal buffer mechanism, and the other end fixedly connected to the limiting plate 10. A transverse sliding mechanism is slidably mounted on the support component. The rear side of the outer plate 8 is fixedly connected to one end of several longitudinal buffer mechanisms. The transverse buffer mechanism includes sliders 11 and second tension springs 12. Two sliders 11 are provided, each slidably connected to the outer wall of one of the connecting rods 9. The outer wall of the connecting rods 9 is fitted with a second tension spring 12, one end of which is fixedly connected to one side of the slider 11, and the other end is fixedly connected to the outside of the longitudinal buffer mechanism. A rotating component is rotatably mounted on the outer plate 8 and the transverse sliding mechanism. Between the buffer mechanisms, the rotating parts include a connecting seat 13, a support plate 14, and a mounting seat 15. The rear side of the connecting seat 13 is fixedly connected to the front side of the transverse buffer mechanism. The support plate 14 is rotatably connected inside the connecting seat 13. The mounting seat 15 is rotatably sleeved on one end of the support plate 14. The front side of the mounting seat 15 is fixedly connected to the rear side of the outer plate 8. The inner side of the outer plate 8 drives the mounting seat 15 to move. The mounting seat 15 drives the support plate 14 to move. The support plate 14 drives the connecting seat 13 to move. Thus, the connecting seat 13 drives the slider 11 to move outward on the connecting rod 9 towards the connecting block 6. At this time, the support plate 14 expands towards the front side of the anti-collision beam 1 between the connecting seat 13 and the mounting seat 15. The slider 11 drives the second tension spring 12 to stretch, thereby providing transverse buffering of the impact force.
[0027] The elastic support is sleeved on the outside of the adjacent support and is fixedly connected between the adjacent transverse buffer mechanisms. The elastic support includes a support spring 16, which is sleeved on the outside of the support and its two ends are fixedly connected to one side of the adjacent transverse buffer mechanism. As the position of the adjacent slider 11 changes, the adjacent slider 11 causes the support spring 16 to compress, thereby buffering the impact force on the slider 11, thereby further buffering the impact force and increasing the impact resistance of the anti-collision beam 1 and the outer plate 8.
[0028] As described above, the specific implementation of this utility model is as follows: When the outer plate 8 is impacted, the outer plate 8 moves towards the front side of the anti-collision beam 1. At this time, the outer plate 8 drives the support rod 7 to move, the support rod 7 drives the connecting block 6 to move, and the connecting block 6 drives the moving rod 3 to move. In turn, the moving rod 3 drives the connecting plate 4 to move, and the connecting plate 4 drives the first tension spring 5 to stretch, so that the outer plate 8 can be longitudinally buffered when subjected to impact force. At the same time, the inner side of the outer plate 8 drives the mounting seat 15 to move, the mounting seat 15 drives the support plate 14 to move, and the support plate 14 drives the connecting seat... 13 moves, thereby connecting seat 13 drives slider 11 to move outward on connecting rod 9 towards connecting block 6. At this time, support plate 14 expands towards the front of anti-collision beam 1 between connecting seat 13 and mounting seat 15. Slider 11 drives second tension spring 12 to stretch, thereby buffering the impact force laterally. Then, due to the change in position of adjacent slider 11, adjacent slider 11 drives support spring 16 to compress, thereby buffering the impact force on slider 11, thereby further buffering the impact force, thereby increasing the impact resistance of anti-collision beam 1 and outer plate 8.
[0029] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
