[0032] The following describes the anti-collision bar assembly 1 according to an embodiment of the utility model with reference to the accompanying drawings.

[0033] like Figure 1-Figure 4 As shown, the crash bar assembly 1 according to the embodiment of the utility model includes a crash bar 100 , a channel plate 200 and a vertical connecting member 300 .

[0034] The bumper bar 100 extends horizontally. The grooved plate 200 is constructed with an upper connecting portion 210, a lower connecting portion 220 and a rear side plate portion 230 connected to the rear sides of the upper connecting portion 210 and the lower connecting portion 220, the upper connecting portion 210 is connected to the top surface of the bumper bar 100, and the lower connecting portion 220 is connected to the bottom surface of the bumper bar 100. The vertical connecting member 300 is suitable for being installed on the front connecting beams on both sides of the frame and extending downward, and the vertical connecting members 300 on both sides are arranged at intervals along the length direction of the grooved plate 200. The grooved plate 200 is installed at the bottom of the vertical connecting member 300. Among them, the rear side plate portion 230 is constructed with a wave portion 201 protruding to the rear at the connection with the vertical connecting member 300, and the width of the wave portion 201 of the upper connecting portion 210 and the lower connecting portion 220 is increased.

[0035] For example, the bumper bar 100 is formed by a hot forming stamping process, and a plurality of vertical connectors 300 are welded at intervals on the wave portion 201 of the trough plate 200. At the same time, the vertical connectors 300 are welded to the upper surface and the rear side surface of the trough plate 200, so that the connectors 300 remain fixed to the trough plate 200 and the bumper bar 100. A trapezoidal or triangular anti-collision reinforcement structure can be constructed between the wave portion 201 and the bumper bar 100, and the vertical connectors 300 can also be connected to the bumper bar 100 at the front side of the trough plate 200.

[0036] According to the bumper assembly 1 of the embodiment of the utility model, the bumper assembly 1 is connected to the grooved plate 200 through the bumper 100, the vertical connecting member 300 is connected to the grooved plate 200, and the grooved plate 200 is respectively connected to the vertical connecting member 300 and the bumper 100, so that the connection structure is more reliable. In addition, the grooved plate 200 is constructed with a wave portion 201 protruding backward at the connection of the vertical connecting plate 200, so that a triangular or trapezoidal anti-collision reinforcement structure is provided on the rear side of the bumper 100. When the bumper 100 is impacted, the impact force is first transmitted to the wave portion 201 of the grooved plate 200. After the wave portion absorbs a part of the impact force, the impact force will be transmitted to the vertical connecting member 300, thereby increasing the anti-collision performance of the bumper assembly 1. Furthermore, the grooved plate 200 is welded to the bumper bar 100 and the vertical connector 300 is welded to the grooved plate 200, thereby increasing the connection area of ​​the bumper bar 100 and reducing the thickness of the bumper bar 100 to a certain extent, which is beneficial to the lightweighting of the bumper bar assembly 1.

[0037] Therefore, the anti-collision bar assembly 1 according to the embodiment of the utility model has the advantages of reliable connection, high structural strength, strong impact resistance, etc.

[0038] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the rear side plate 230 is spaced apart from the bumper bar 100. By spacing the rear side plate 230 apart from the bumper bar 100, more deformation space can be provided during a collision, so that the bumper bar 100 can more easily absorb and disperse the collision force when it is hit, thereby reducing the impact force on the vehicle and passengers, thereby protecting the vehicle and passengers. Similarly, setting the spacing between the rear side plate 230 and the bumper bar 100 can effectively reduce the distortion and damage of the vehicle structure during a collision, reduce the impact of the accident on the vehicle, protect the main structure of the vehicle, and thus improve the overall safety of the vehicle.

[0039] In some specific embodiments of the present invention, Figure 2 As shown, the cross-section of the bumper bar 100 is constructed into a trapezoid, the front side and the rear side of the bumper bar 100 are parallel to each other, the distance between the top surface and the bottom surface of the bumper bar 100 gradually decreases from front to back, and the distance between the upper connecting part 210 and the lower connecting part 220 gradually decreases from front to back.

[0040] The cross-sectional shape of the trapezoidal structure of the anti-collision bar 100 can better fit with the groove plate 200, which is convenient for docking and fixing during installation. The distance between the top surface and the bottom surface gradually decreases from front to back, and the distance between the upper connecting part 210 and the lower connecting part 220 of the groove plate 200 gradually decreases, making installation easier and faster. At the same time, since the distance between the top surface and the bottom surface gradually decreases from front to back, the structure is more stable, which can increase the structural strength of the anti-collision bar 100 and improve the overall anti-collision ability and safety.

[0041] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the front side and the rear side of the bumper bar 100 are both constructed with reinforcement grooves 101, and the reinforcement grooves 101 extend along the length direction of the bumper bar 100. The reinforcement grooves 101 are symmetrically arranged on the left and right sides of the bumper bar 100, respectively. The arrangement of the reinforcement grooves 101 can effectively enhance the overall structural strength of the bumper bar 100, and the deformation and damage of the bumper bar assembly 1 can be reduced when the vehicle is subjected to impact force, thereby improving the anti-collision effect. At the same time, the weight-reducing grooves 101 can also absorb and disperse the impact force during a collision, reduce the damage to the vehicle caused by the impact force, play a buffering role, and improve the service life of the bumper bar 100.

[0042] In some specific embodiments of the present invention, Figure 3 As shown, the vertical connector 300 is constructed with multiple rows of mounting holes 301 along the height direction. Multiple rows of mounting holes 301 can provide a variety of different height positions for installation. The appropriate hole position can be selected for installation according to the needs, which is more flexible and convenient, adapts to the needs of different vehicle models or vehicle body structures, and improves the accuracy and stability of installation. Through the multiple rows of mounting holes 301, the height can be adjusted according to the actual situation, so that the bumper assembly 1 can reach the best position and height during installation. After selecting a suitable position for fixed installation, the connection stability between the bumper 100 and the vehicle can be enhanced, and the possibility of loosening during driving can be reduced.

[0043] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the vertical connector 300 is configured as a straight tube extending in the vertical direction. The straight tube structure can provide better strength and stability, can effectively connect different components of the bumper assembly 1, enhance the overall structural stability, and enable the bumper to better protect the vehicle and passengers during a collision. In addition, the straight tube structure can increase the overall rigidity of the vertical connector 300, making it more durable and less susceptible to external vibration and impact, thereby increasing the service life of the bumper.

[0044] In some specific embodiments of the present invention, Figure 4As shown, the cross section of the vertical connector 300 is configured as a rectangle. For example, the two sides of the vertical connector 300 are at different heights, and the cross section is in a rectangular shape. This structure can provide a stable installation plane, ensure the stable connection between the vertical connector 300 and the anti-collision bar 100 and the groove plate 200, and ensure the accuracy of the connection. At the same time, the vertical connector 300 with a rectangular structure can better resist external impact or vibration, provide uniform deformation and energy absorption in a collision, and reduce damage caused by local force.

[0045] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the side of the vertical connector 300 facing the front connecting beam is configured with an extension portion 310 extending upward, and multiple rows of mounting holes 301 are formed in the extension portion 310. The structure of the extension portion 310 allows the vertical connector 300 to extend upward toward the side of the front connecting beam, providing more space and angle options for installation, increasing the flexibility of installation, and adapting to the needs of different vehicle models and structures. At the same time, the multiple rows of mounting holes 301 on the extension portion 310 provide a variety of installation positions and height options. Through flexible installation, the bumper assembly 1 can be adjusted and positioned to meet different needs, increasing the convenience and applicability of installation.

[0046] In addition, the structure of the extension portion 310 increases the area of ​​the connection point, improves the stability and support of the connection, helps reduce looseness or shaking during driving, and increases the stability and durability of the overall structure.

[0047] In some specific embodiments of the present invention, Figure 3 As shown, a mounting notch 302 is configured at the front side of the bottom of the vertical connecting member 300 , and the top surface and the rear side surface of the anti-collision bar 100 are respectively connected to the mounting notch 302 .

[0048] The installation notch 302 structure provides a fixed connection point, so that the top surface and rear side surface of the bumper bar 100 can be accurately connected to the bottom front side of the vertical connecting member 300, thereby enhancing the stability of the connection and ensuring that the bumper bar 100 can effectively play a protective role in the event of a collision. Similarly, by installing the notch 302, the connection between the bumper bar 100 and the vertical connecting member 300 is more secure, which can effectively absorb and disperse the impact force generated during the collision, reduce the risk of vehicle damage and occupant injury, and improve driving safety.

[0049] The design of the installation notch 302 makes the installation process simpler and faster, and the installer can more easily connect the anti-collision bar 100 to the vertical connecting member 300, thereby improving installation efficiency and saving labor costs.
