Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive bumper anti-collision beam assembly. Background Technology

[0002] In the development of the automotive industry, people's high attention to vehicle safety has driven continuous innovation in bumper anti-collision beam assembly technology. Its design concept has gradually transformed from initially only meeting basic appearance protection functions to becoming a core component of vehicle collision safety. Early anti-collision beams mostly used simple steel structures, and due to the lack of precise mechanical analysis and simulation methods, the collision protection effect was poor. With the rise of computer technology, the finite element analysis method was widely used in the field of automotive engineering. Engineers were able to optimize its structure and material distribution by accurately calculating the stress distribution and deformation mode of the anti-collision beam during a collision, significantly improving its performance. At the same time, the automotive industry's urgent need for lightweighting has driven the application of new materials such as high-strength steel and aluminum alloys, which combine high strength and low weight, to anti-collision beams, achieving a balance between safety and energy saving while ensuring strength and rigidity.

[0003] Traditional automotive bumper anti-collision beam assemblies mostly employ a single rigid structure design, relying primarily on the material's inherent strength to withstand impact forces during a collision. In the event of a collision, this structure is ineffective at buffering and absorbing energy, and the impact force is rapidly transmitted to the vehicle body, increasing the risk of vehicle deformation and occupant injury. Currently, to address the lack of a buffering structure in anti-collision beams, the industry commonly employs methods such as thickening the steel plates and increasing the overall size of the anti-collision beam to improve its crashworthiness. Increasing the steel plate thickness makes the anti-collision beam more rigid, capable of withstanding greater impact forces to some extent. However, this solution has several drawbacks. On one hand, thicker and larger anti-collision beams significantly increase the vehicle's curb weight, leading to increased fuel consumption and reduced fuel economy, while also increasing carbon dioxide emissions and putting greater pressure on the environment. On the other hand, simply reinforcing the rigidity of the anti-collision beam means it cannot effectively absorb energy through structural deformation in the face of high-intensity collisions. The enormous impact force is directly transmitted to the vehicle frame, causing severe vehicle deformation and potentially even compressing the interior space. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automotive bumper anti-collision beam assembly, which aims to improve the problem that the existing automotive bumper anti-collision beam assemblies mostly adopt a single rigid structure design, mainly relying on the strength of the material itself to resist the impact force during a collision. When a vehicle collides, this structure is difficult to effectively buffer and absorb energy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automotive bumper anti-collision beam assembly, comprising a crossbeam and two fixing plates, wherein sliders are slidably connected to the left and right sides of the crossbeam, and an arc-shaped plate is fixedly connected to the adjacent side of the two sliders. A short shaft is fixedly connected to the rear side of the arc-shaped plate, and a connecting plate is slidably connected to the rear side of the short shaft.

A sleeve is fixedly connected to the outer wall of the slider, and sliders are fixedly connected to the front and rear sides of the sleeve. A sleeve is slidably connected to the outer wall of the sleeve, and a spring is fixedly connected to the inner wall of the sleeve. Holes and slots are provided on the front and rear sides of the sleeve. An installation mechanism is provided on the rear side of the crossbeam for fixed installation.

[0006] As a further description of the above technical solution:

[0007] The installation mechanism includes a first connector, which is disposed on the outer wall of the second fixing plate. A second connector is fixedly connected to the rear side of the first connector. A threaded rod is threadedly connected to the middle of the first connector. A handle is fixedly connected to the front side of the threaded rod. A first fixing block is fixedly connected to the rear side of the threaded rod. A second fixing block is fixedly connected to the outer wall of the first fixing block. A third connector is disposed on the rear side of the second connector. A hole is formed in the middle of the third connector.

[0008] As a further description of the above technical solution:

[0009] The crossbeam has a third hole in its middle, and the connecting plate has a second hole in its middle.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the second slider is slidably connected to the inner wall of the slot, and a fixing block three is fixedly connected to the rear side of the short shaft near the edge.

[0012] As a further description of the above technical solution:

[0013] The front side of the short shaft is slidably connected to the inner wall of hole three, and the rear side of the short shaft is slidably connected to the inner wall of hole two.

[0014] As a further description of the above technical solution:

[0015] The front side of the connector three is threaded with multiple bolts one near the edge, and the front side of the connector one is fixedly connected with multiple bolts two near the edge.

[0016] As a further description of the above technical solution:

[0017] The rear side of the connector three is fixedly connected to the connecting plate two, and the outer wall of the handle is fixedly connected to the anti-slip pad.

[0018] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, through the combination structure of arc plate, slider, sleeve and spring, when subjected to external impact, the arc plate drives the slider to squeeze the sleeve after being subjected to force, so that spring one and spring two intervene one after another, realizing the step-by-step absorption and buffering of the impact force, which can effectively reduce the impact force of the collision on the vehicle body and the occupants, and significantly improve the vehicle safety protection level.

[0022] 2. In this utility model, a fixing method of connecting parts engaging and threaded rod linkage is adopted. By connecting parts two and three and turning the handle to drive the threaded rod to rotate, the fixing block can engage with the hole on connecting part three, realizing the rapid and stable installation of the crossbeam and the car, greatly shortening the installation time and improving the assembly efficiency.
