Description

Technical Field

[0001] The utility model relates to the technical field of automobile longitudinal beams, in particular to an impact-resistant automobile longitudinal beam which is easy to install. Background Art

[0002] With the continuous development of the automotive industry, cars are playing an increasingly important role in people's daily lives and transportation. At the same time, demands for vehicle safety and assembly convenience are also increasing. As a key component in the vehicle chassis structure, the performance and installation method of the longitudinal beam directly affect the overall safety of the vehicle, as well as the efficiency of production and maintenance.

[0003] In existing technology, when a car crashes, the longitudinal beams are required to withstand tremendous impact forces from all directions. Typically, after being subjected to the impact, the longitudinal beams directly transfer most of the force to other parts of the car body. This can cause the longitudinal beams themselves to severely deform or even break, making them unable to effectively support the car body and protect the safety of the passengers. Furthermore, the passengers in the car are subjected to greater impact forces, increasing the risk of injury. Utility Model Content

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: an impact-resistant automobile longitudinal beam that is easy to install, comprising: a transverse support rod, the two sides of the transverse support rod are fixedly connected to the beam body, the outer side of the beam body is fixedly connected to an arc-shaped protective plate, and the top of the beam body is fixedly connected to a top protective plate; a connecting component, the outer side of the connecting component is rotatably connected to the outer side of the beam body; a buffer component, the outer side of the buffer component is fixedly connected to the inner side of the beam body, and the buffer components are linearly arranged along the inner wall of the beam body. When an external force impacts the longitudinal beam due to a collision of the car or other circumstances, the arc-shaped protective plate, as the outermost protective structure of the longitudinal beam, first bears the impact force from the outside. The arc-shaped design of the arc-shaped protective plate can disperse the impact force to a certain extent, so that it will not be concentrated on a certain point, thereby reducing the local impact pressure. At the same time, the top protective plate will also share part of the impact force from above, and together with the arc-shaped protective plate, it constitutes a preliminary protection for the beam body.

[0005] The buffer component includes a reinforcement plate, the outer side of which is fixedly connected to a fixed column. The top of the inner wall of the fixed column is fixedly connected to a compression spring. The bottom end of the compression spring is fixedly connected to a sliding rod. The top end of the sliding rod is fixedly connected to an arc-shaped support plate. When the impact force is transmitted to the beam body and acts on the buffer component, the impact force compresses the arc-shaped support plate. When the arc-shaped support plate is compressed, it pushes the sliding rod fixedly connected to its top end to slide upward along the inner wall of the fixed column.

[0006] Preferably, the outer side of the reinforcing plate is fixedly connected to the inner wall of the beam body, and the reinforcing plate is linearly arranged along the inner wall of the beam body. The inner wall of the beam body is fixedly connected to the bottom of the fixed column, and the fixed column is linearly arranged along the inner wall of the beam body. In the process of the sliding rod sliding upward, the compression spring will be compressed, thereby converting the energy carried by the impact force into its own elastic potential energy for storage, thereby achieving the absorption of the impact force energy.

[0007] Preferably, the outer wall of the sliding rod is slidably connected to the inner wall of the fixed column, and both sides of the arc-shaped support plate are fixedly connected to the inner wall of the beam body. The arrangement of the reinforcing plate and the arc-shaped support plate can enhance the structural strength of the beam body.

[0008] Preferably, the connecting component includes a plug-in plate, the outer side of which is fixedly connected to a mounting plate, and the inner wall of which is slidably connected to a sliding block via a sliding groove. When installing the longitudinal beam, the installer can use the mounting plate in the connecting component to preliminarily fix the entire longitudinal beam to the corresponding position on the vehicle chassis. The mounting plate is then fastened to the vehicle chassis through the mounting holes on the mounting plate.

[0009] Preferably, the outer side of the sliding block is rotatably connected to the outer side of the beam body, and the outer side of the beam body is plugged into the inner side of the plug board. The installer manually pushes the beam body and adjusts the deflection position of the beam body relative to the plug board through the sliding block. When the position of the beam body is relative to the position of the plug board, the beam body can be inserted into the plug board.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. This utility model incorporates a buffer component. When an impact force is transmitted to the beam and acts on the buffer component, the impact force compresses the curved support plate. This pressure pushes the sliding rod, fixed to its top end, upward along the inner wall of the fixed column. As the sliding rod slides upward, the compression spring is compressed, converting the energy carried by the impact force into its own elastic potential energy for storage, thereby absorbing the impact energy and achieving a buffering effect.

[0012] 2. By providing connecting components, the present invention allows installers to initially secure the entire longitudinal beam to the corresponding position on the vehicle chassis using the mounting plate. Installers then manually push the beam and use a sliding block to adjust the beam's deflection relative to the plug-in plate. When the beam's position aligns with the plug-in plate, the beam can be inserted into the plug-in plate. Once the beam is securely inserted, the plug-in plate can be bolted to the beam, making installation of the vehicle's longitudinal beam easier and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0020] Example: See Figure 1 - Figure 5 The utility model provides a technical solution: an impact-resistant automobile longitudinal beam that is easy to install, comprising:

[0021] Transverse support rod 1, both sides of the transverse support rod 1 are fixedly connected with beam body 2, the outer side of beam body 2 is fixedly connected with arc-shaped protective plate 3, and the top of beam body 2 is fixedly connected with top protective plate 4. The longitudinal beam is composed of transverse support rod 1 and beam body 2 and other components. When the car collides and other situations cause external forces to impact the longitudinal beam, the arc-shaped protective plate 3, as the outermost protective structure of the longitudinal beam, first bears the impact force from the outside. The arc-shaped design of the arc-shaped protective plate 3 can disperse the impact force to a certain extent, so that it will not be concentrated on a certain point, thereby reducing the local impact pressure. At the same time, the top protective plate 4 will also share part of the impact force from above, and together with the arc-shaped protective plate 3, it constitutes the initial protection for the beam body 2, preventing the beam body 2 from being directly subjected to excessive impact force and causing serious deformation or damage;

[0022] Buffer component 6, the outer side of the buffer component 6 is fixedly connected to the inner side of the beam body 2, and the buffer component 6 is linearly arranged along the inner wall of the beam body 2, the buffer component 6 includes a reinforcing plate 61, the outer side of the reinforcing plate 61 is fixedly connected to a fixing column 62, the top of the inner wall of the fixing column 62 is fixedly connected to a compression spring 64, the bottom end of the compression spring 64 is fixedly connected to a sliding rod 63, and the top end of the sliding rod 63 is fixedly connected to an arc-shaped support plate 65, the outer side of the reinforcing plate 61 is fixedly connected to the inner wall of the beam body 2, and the reinforcing plate 61 is linearly arranged along the inner wall of the beam body 2, the inner wall of the beam body 2 is fixedly connected to the bottom of the fixing column 62, and the fixing column 62 is linearly arranged along the inner wall of the beam body 2, the outer wall of the sliding rod 63 is slidably connected to the inner wall of the fixing column 62, and the two sides of the arc-shaped support plate 65 are fixedly connected to the inner wall of the beam body 2. When the impact force is transmitted to the beam body 2 and acts on the buffer component 6, the impact force will compress the arc-shaped support plate 65. When the arc-shaped support plate 65 is subjected to pressure, it pushes the sliding rod 63 fixedly connected to its top end to slide upward along the inner wall of the fixed column 62. During the upward sliding process of the sliding rod 63, the compression spring 64 is compressed, thereby converting the energy carried by the impact force into its own elastic potential energy for storage, thereby absorbing the energy of the impact force and achieving a buffering effect. Among them, the arrangement of the reinforcing plate 61 and the arc-shaped support plate 65 can enhance the structural strength of the beam body 2. Moreover, because the multiple buffer components 6 are linearly arranged along the inner wall of the beam body 2, the numerous buffer components 6 work simultaneously, which can evenly disperse the impact force at various locations on the inner wall of the beam body 2, avoiding excessive deformation or damage of the beam body 2 due to excessive local force, and further enhancing the overall impact resistance of the longitudinal beam.

[0023] The connecting component 5, the outer side of the connecting component 5 is rotatably connected to the outer side of the beam body 2; the connecting component 5 includes a plug-in plate 51, the outer side of the plug-in plate 51 is fixedly connected to the mounting plate 52, the inner wall of the plug-in plate 51 is slidably connected to the sliding block 54 through the slide groove 53, the outer side of the sliding block 54 is rotatably connected to the outer side of the beam body 2, and the outer side of the beam body 2 is plugged into the inner side of the plug-in plate 51. When installing the longitudinal beam, the installer can use the mounting plate 52 in the connecting component 5 to preliminarily fix the entire longitudinal beam to the corresponding position of the automobile chassis. The mounting plate 52 is fastened to the automobile chassis through the mounting holes on the mounting plate 52. The installer then manually pushes the beam body 2 and adjusts the deflection position of the beam body 2 relative to the plug-in plate 51 through the sliding block 54. When the position of the beam body 2 is relative to the position of the plug-in plate 51, the beam body 2 can be inserted into the plug-in plate 51. At this time, the sliding block 54 slides in the slide groove 53 as the beam body 2 moves. After the beam body 2 is inserted, the plug-in plate 51 and the beam body 2 can be fixed by bolts, which helps the installer to complete the installation of the automobile longitudinal beam more easily and efficiently.

[0024] Working principle:

[0025] During use, the longitudinal beam is composed of transverse support rods 1 and a beam body 2. When an external force impacts the longitudinal beam, such as in a vehicle collision, the curved protective plate 3, acting as the outermost protective structure of the longitudinal beam, is the first to withstand the external impact force. The curved design of the curved protective plate 3 disperses the impact force to a certain extent, preventing it from being concentrated at a single point, thereby reducing the local impact pressure. Simultaneously, the top guard plate 4 also shares some of the impact force from above, and together with the curved protective plate 3, provides initial protection for the beam body 2, preventing the beam body 2 from being directly subjected to excessive impact forces and causing serious deformation or damage.

[0026] When the impact force is transmitted to the beam body 2 and acts on the buffer component 6, the impact force compresses the arc-shaped support plate 65. Under pressure, the arc-shaped support plate 65 pushes the sliding rod 63 fixedly connected to its top end to slide upward along the inner wall of the fixed column 62. As the sliding rod 63 slides upward, the compression spring 64 is compressed, thereby converting the energy carried by the impact force into its own elastic potential energy for storage, thereby absorbing the energy of the impact force and achieving a buffering effect. The provision of the reinforcing plate 61 and the arc-shaped support plate 65 can enhance the structural strength of the beam body 2.

[0027] Moreover, since a plurality of buffer components 6 are arranged linearly along the inner wall of the beam body 2, and a large number of buffer components 6 work simultaneously, the impact force can be evenly dispersed at various positions of the inner wall of the beam body 2, thereby avoiding excessive deformation or damage of the beam body 2 due to excessive local force, and further enhancing the overall impact resistance of the longitudinal beam.

[0028] When installing the longitudinal beam, the installer can use the mounting plate 52 in the connecting component 5 to initially fix the entire longitudinal beam to the corresponding position on the vehicle chassis. The mounting plate 52 is fastened to the vehicle chassis through the mounting holes on the mounting plate 52. The installer then manually pushes the beam body 2 and uses the sliding block 54 to adjust the deflection position of the beam body 2 relative to the plug-in plate 51. When the position of the beam body 2 is relative to the position of the plug-in plate 51, the beam body 2 can be inserted into the plug-in plate 51. At this time, the sliding block 54 slides within the chute 53 as the beam body 2 moves. After the beam body 2 is inserted, the plug-in plate 51 can be fixed to the beam body 2 using bolts, which helps the installer complete the installation of the vehicle longitudinal beam more easily and efficiently.
