Description

Technical Field

[0001] This utility model relates to the field of automotive frame technology, and in particular to a front connecting vertical beam for improving the strength and stability of the vehicle body. Background Technology

[0002] The front connecting beam is an important structural component located at the front of the vehicle body. It is horizontally installed and firmly connects the relevant structural components on both sides of the vehicle body. Through reliable connection methods, such as welding and bolting, the left and right side components are tightly connected. It not only bears the responsibility of distributing and transmitting various loads from the front of the vehicle during vehicle operation, including collision forces and inertial forces, effectively ensuring the integrity and stability of the vehicle body structure, but also provides the mounting base for various auxiliary equipment at the front, such as headlights and bumpers, playing a key role in maintaining the overall performance and safety of the vehicle.

[0003] Off-road vehicles frequently travel on rough and uneven terrain, such as rocky roads and potholes. When driving on such terrain, the front corners of the vehicle frame are prone to collisions with rocks and other obstacles, resulting in strong impacts on the front corners and causing damage to the front of the vehicle. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art that when a vehicle is driving on a complex road with many obstacles, the front corner of the vehicle frame is prone to collision with rocks and other obstacles, resulting in strong impact force on the front corner of the vehicle and damage to the front of the vehicle. The present invention proposes a front connecting vertical beam to improve the strength and stability of the vehicle body.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a front connecting vertical beam for improving the strength and stability of a vehicle body, comprising a vertical beam body, wherein a composite impact-resistant energy-absorbing plate is fixedly installed on the outer side of the vertical beam body, the composite impact-resistant energy-absorbing plate comprising a mounting plate base layer, a honeycomb aluminum core energy-absorbing layer and a high-strength steel outer layer, wherein the honeycomb aluminum core energy-absorbing layer is fixedly bonded to the outer side of the mounting plate base layer, and the high-strength steel outer layer is fixedly bonded to the outer side of the honeycomb aluminum core energy-absorbing layer.

[0006] Preferably, the mounting plate base layer is fixedly connected to the mounting locator in a centrally symmetrical manner, and the two ends of the vertical beam body are respectively symmetrically provided with positioning grooves, and one end of the mounting locator is movably inserted through the interior of the positioning groove.

[0007] Preferably, the installation locator includes a locating block and two locating rods, one end of the locating block being movably engaged inside a locating groove, and the other ends of the two locating rods penetrating inside the other locating groove.

[0008] Preferably, the two positioning rods abut against the two ends of the inner wall of another positioning groove.

[0009] Preferably, a disc is movably sleeved at the other end of the positioning rod, and a mounting nut is threaded onto the other end of the positioning rod. The disc fits against one side of another positioning groove.

[0010] Preferably, the vertical beam body has symmetrical mounting grooves in the middle.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the base layer of the mounting plate in the composite impact-resistant energy-absorbing plate is rigidly supported and fixed to the honeycomb aluminum core energy-absorbing layer, and connected to the main body of the vertical beam. The remaining impact force is evenly transmitted to the vehicle frame, avoiding local overload. The honeycomb structure in the honeycomb aluminum core energy-absorbing layer undergoes progressive collapse under pressure. The kinetic energy is converted into deformation energy by plastic deformation such as bending and folding of the hole walls, which significantly reduces the peak impact force. The high-strength steel outer layer, as the outermost layer, withstands direct impact through high hardness and toughness. The impact force is dispersed through plastic deformation to avoid stress concentration in local areas. The impact force passes through the high-strength steel outer layer, the honeycomb aluminum core energy-absorbing layer, and the base layer of the mounting plate in sequence to form a three-level attenuation path, thereby improving the strength and stability of the vehicle body.

[0013] 2. In this utility model, by engaging one end of the positioning block with the inside of a positioning groove, and with two positioning rods abutting against the two ends of the inner wall of another positioning groove, a stable positioning structure is formed. Combined with the fastening of the disc and the mounting nut, the main body of the vertical beam is tightly connected to the composite impact-resistant energy-absorbing plate, which effectively enhances the stability of the overall structure. When subjected to impact, it can greatly reduce the risk of loosening and displacement of the plate, and ensure the integrity of the structure. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a front-end connecting vertical beam to improve the strength and stability of the vehicle body, including a vertical beam body 1. A composite impact-resistant energy-absorbing plate 2 is fixedly installed on the outer side of the vertical beam body 1. The composite impact-resistant energy-absorbing plate 2 includes a mounting plate base 21, a honeycomb aluminum core energy-absorbing layer 22, and a high-strength steel outer layer 23. The honeycomb aluminum core energy-absorbing layer 22 is fixedly bonded to the outer side of the mounting plate base 21, and the high-strength steel outer layer 23 is fixedly bonded to the outer side of the honeycomb aluminum core energy-absorbing layer 22.

[0022] The specific setup and function of this embodiment are described below. A composite impact-resistant energy-absorbing plate 2 is integrated on the outside of the main body 1 of the vertical beam. The mounting plate base 21 in the composite impact-resistant energy-absorbing plate 2 is rigidly supported and fixed to the honeycomb aluminum core energy-absorbing layer 22, and connected to the main body 1 of the vertical beam. The remaining impact force is evenly transmitted to the vehicle frame to avoid local overload. The honeycomb structure in the honeycomb aluminum core energy-absorbing layer 22 undergoes progressive collapse under pressure. The kinetic energy is converted into deformation energy by plastic deformation such as bending and folding of the hole walls, which significantly reduces the peak impact force. The high-strength steel outer layer 23, as the outermost layer, withstands direct impact through high hardness and toughness. The impact force is dispersed through plastic deformation to avoid stress concentration in local areas. The impact force passes through the high-strength steel outer layer 23, the honeycomb aluminum core energy-absorbing layer 22, and the mounting plate base 21 in sequence to form a three-level attenuation path, thereby improving the strength and stability of the vehicle body.

[0023] Example 2: Figure 1 - Figure 4As shown, the front connecting vertical beam for improving the strength and stability of the vehicle body in this utility model includes a vertical beam body 1. A composite impact-resistant energy-absorbing plate 2 is fixedly installed on the outer side of the vertical beam body 1. The composite impact-resistant energy-absorbing plate 2 includes a mounting plate base 21, a honeycomb aluminum core energy-absorbing layer 22, and a high-strength steel outer layer 23. The honeycomb aluminum core energy-absorbing layer 22 is fixedly bonded to the outer side of the mounting plate base 21, and the high-strength steel outer layer 23 is fixedly bonded to the outer side of the honeycomb aluminum core energy-absorbing layer 22. An installation locator 3 is fixedly connected to the inner side of the mounting plate base 21 in a centrally symmetrical manner. Positioning grooves 1 are symmetrically opened at both ends of the vertical beam body 1. 1. One end of the mounting positioner 3 is movably inserted through the interior of the positioning groove 11. The mounting positioner 3 includes a positioning block 31 and two positioning rods 32. One end of the positioning block 31 is movably engaged inside the interior of one positioning groove 11. The other ends of the two positioning rods 32 are inserted through the interior of another positioning groove 11. The two positioning rods 32 abut against the two ends of the inner wall of the other positioning groove 11. The other end of the positioning rods 32 is movably sleeved with a disc 33. The other end of the positioning rods 32 is threaded with a mounting nut. The disc 33 fits against one side of the other positioning groove 11. The middle of the vertical beam body 1 is symmetrically provided with mounting grooves 12.

[0024] The overall effect of this embodiment is that when installing the composite impact-resistant energy-absorbing plate 2, one end of the positioning block 31 is first engaged inside a positioning groove 11, while the two positioning rods 32 abut against the two ends of the inner wall of another positioning groove 11, forming a stable positioning structure. Then, with the tightening of the disc 33 and the mounting nut, the vertical beam body 1 is tightly connected to the composite impact-resistant energy-absorbing plate 2, which effectively enhances the stability of the overall structure. When subjected to impact, it can greatly reduce the risk of plate loosening and displacement, and ensure the structural integrity.

[0025] The usage and working principle of this device are as follows: A composite impact-resistant energy-absorbing plate 2 is integrated on the outside of the main body 1 of the vertical beam. The mounting plate base 21 in the composite impact-resistant energy-absorbing plate 2 is rigidly supported to fix the honeycomb aluminum core energy-absorbing layer 22 and connected to the main body 1 of the vertical beam. The remaining impact force is evenly transmitted to the vehicle frame to avoid local overload. When the honeycomb structure in the honeycomb aluminum core energy-absorbing layer 22 is compressed, it undergoes progressive collapse. The kinetic energy is converted into deformation energy by plastic deformation such as bending and folding of the hole wall, which significantly reduces the peak impact force. The high-strength steel outer layer 23, as the outermost layer, withstands the direct impact with high hardness and toughness. The impact force is dispersed by plastic deformation to avoid stress concentration in a local area. The impact force passes through the high-strength steel outer layer 23, the honeycomb aluminum core energy-absorbing layer 22, and the mounting plate base 21 in sequence to form a three-level attenuation path.

[0026] When installing the composite impact-resistant energy-absorbing plate 2, first, one end of the positioning block 31 is engaged inside a positioning groove 11, while the two positioning rods 32 abut against the two ends of the inner wall of another positioning groove 11, forming a stable positioning structure. Then, with the tightening of the disc 33 and the mounting nut, the vertical beam body 1 is tightly connected to the composite impact-resistant energy-absorbing plate 2.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
