Technical Field

[0001] This utility model relates to the field of front bumpers, and more particularly to a front bumper for automobiles. Background Technology

[0002] The front bumper is located at the very front of the vehicle, below the hood, and wraps around the lower part of the front end. Specifically, it's positioned below the headlights, adjacent to the front grille, forming the visual focal point of the vehicle's front end. The front bumper typically extends to the fog light areas on both sides, forming a robust protective beam.

[0003] Functionally, the front bumper is the "first line of defense" in a vehicle collision, protecting the components inside the engine compartment and the safety of the occupants by absorbing and dispersing the impact force.

[0004] Therefore, it is necessary to provide a new type of automotive front bumper to solve the aforementioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a front bumper for automobiles.

[0006] The car front bumper provided by this utility model includes a body, a connecting frame fixed at the front end of the body, the connecting frame having a tapered structure along the direction away from the body, and a front panel fixedly connected to the end of the connecting frame away from the body. A crash plate is detachably connected to the body, and the crash plate is located at the front end of the front panel.

[0007] The anti-collision plate includes an outer protective plate, an inner protective plate, and a central plate. The outer protective plate and the inner protective plate are fixedly connected to both sides of the central plate, respectively. The interior of the central plate has a honeycomb structure, and the aperture of the honeycomb structure of the central plate gradually increases along the direction away from the outer protective plate.

[0008] Preferably, at least one connecting device is provided on both sides of the anti-collision plate, and the end of the connecting device away from the anti-collision plate is connected to the main body.

[0009] Preferably, the connecting device includes a bending plate, an insert plate, a positioning frame, and a positioning bolt. One end of the bending plate is fixed to the anti-collision plate, and the other end of the bending plate is fixedly connected to the insert plate. The positioning frame is fixed to the main body. The insert plate can be moved into the inner cavity of the positioning frame, and the size of the insert plate is adapted to the size of the inner cavity of the positioning frame. The positioning bolt is inserted into a through hole opened in the side wall of the positioning frame, and the positioning bolt is threadedly connected to the insert plate.

[0010] Preferably, a vent hole is provided at the center of the anti-collision plate, and an installation frame is fixed on the side wall of the anti-collision plate corresponding to the vent hole, and a vent fence is fixed on the installation frame.

[0011] Preferably, when there are two or more connecting devices on one side of the anti-collision plate, the spacing between the positioning frames in two adjacent connecting devices is greater than the length of the insert plate.

[0015] Compared with related technologies, the automotive front bumper provided by this utility model has the following beneficial effects:

[0016] 1. As the aperture of the honeycomb structure in the central plate gradually increases along the direction away from the outer protective plate, the small-aperture honeycomb structure has higher initial stiffness and impact resistance, which can quickly absorb impact energy in the early stage of the collision and prevent energy from being directly transferred to the inner protective plate. The large-aperture honeycomb structure continues to dissipate the remaining energy in the subsequent stage through deformation states such as bending of the hole wall, thus prolonging the collision time. Moreover, this kind of gradually changing honeycomb aperture can effectively alleviate stress concentration and improve the overall buffering effect.

[0017] 2. When installing the crash barrier, move the insert plate into the positioning frame. The insert plate is supported by the positioning frame, eliminating the need for workers to support the crash barrier and facilitating subsequent operations. Tighten the positioning bolts to connect the crash barrier to the main body. Due to its detachable design, the crash barrier can be replaced individually if it becomes deformed.

Figure 4 for Figure 3 A partial structural diagram of the structure shown; Figure 5 for Figure 1 The diagram shows the internal structure of the crash barrier.

[0026] In the specific implementation process, such as Figures 1-5 As shown, it includes a body 1, a connecting frame 2 fixed to the front end of the body 1, the connecting frame 2 having a tapered structure along the direction away from the body 1, and a front panel 3 fixedly connected to the end of the connecting frame 2 away from the body 1. A crash plate is detachably connected to the body 1, and the crash plate is located at the front end of the front panel 3.

[0027] The anti-collision plate includes an outer protective plate 4, an inner protective plate 5, and a central plate 6. The outer protective plate 4 and the inner protective plate 5 are fixedly connected to both sides of the central plate 6, respectively. The interior of the central plate 6 has a honeycomb structure, and the aperture of the honeycomb structure of the central plate 6 gradually increases in the direction away from the outer protective plate 4. Since the aperture of the honeycomb structure of the central plate 6 gradually increases in the direction away from the outer protective plate 4, the small-aperture honeycomb structure has higher initial stiffness and impact resistance, which can quickly absorb impact energy in the initial stage of collision and prevent energy from being directly transferred to the inner protective plate 5. The large-aperture honeycomb structure continues to dissipate the remaining energy in the subsequent stage through deformation states such as bending of the hole walls, prolonging the collision time. Moreover, this kind of gradually changing honeycomb aperture can effectively alleviate stress concentration and improve the overall buffering effect.

[0028] At least one connecting device is provided on both sides of the anti-collision plate, and the end of the connecting device away from the anti-collision plate is connected to the body 1;

[0029] The connecting device includes a bending plate 7, an insert plate 8, a positioning frame 9, and a positioning bolt 10. One end of the bending plate 7 is fixed to the anti-collision plate, and the other end of the bending plate 7 is fixedly connected to the insert plate 8. The positioning frame 9 is fixed to the main body 1. The insert plate 8 can be moved into the inner cavity of the positioning frame 9, and the size of the insert plate 8 is adapted to the size of the inner cavity of the positioning frame 9. The positioning bolt 10 is inserted into the through hole opened in the side wall of the positioning frame 9, and the positioning bolt 10 is threadedly connected to the insert plate 8. Through the connecting device, when installing the anti-collision plate, the insert plate 8 is moved into the positioning frame 9. The insert plate 8 is supported by the positioning frame 9, eliminating the need for workers to support the anti-collision plate, which facilitates subsequent operations. Tightening the positioning bolt 10 realizes the connection between the anti-collision plate and the main body 1. Through the detachable design, the anti-collision plate can be replaced individually after deformation.

[0030] A ventilation hole 11 is provided at the center of the anti-collision plate, and an installation frame 12 is fixed on the side wall of the anti-collision plate corresponding to the ventilation hole 11. A ventilation grille 13 is fixed on the installation frame 12.

[0031] When there are two or more connecting devices on one side of the anti-collision plate, the spacing between the positioning frames 9 in two adjacent connecting devices is greater than the length of the insert plate 8. During installation, the insert plate 8 on the middle connecting device among the multiple connecting devices is placed between the two positioning frames 9, and then the anti-collision plate is lowered so that the insert plate 8 rests on the positioning frame 9, and then the subsequent installation work is carried out.

[0032] The rear end of the anti-collision plate is fixedly connected with a plurality of horizontally arranged reinforcing ribs 14, and the top of the anti-collision plate is fixedly connected with a baffle 15. The inclined surface of the top of the connecting frame 2 has the same inclination angle as the baffle 15. The reinforced ribs 14 improve the firmness of the anti-collision plate.

[0034] The outer protective plate 4 is made of aluminum alloy, and the inner protective plate 5 is made of titanium alloy.

[0035] The working principle provided by this utility model is as follows: Since the aperture of the honeycomb structure of the central plate 6 gradually increases along the direction away from the outer protective plate 4, the small aperture honeycomb structure has higher initial stiffness and impact resistance, and quickly absorbs impact energy in the early stage of collision, preventing energy from being directly transferred to the inner protective plate 5. The large aperture honeycomb structure continues to dissipate the remaining energy in the subsequent stage through deformation states such as bending of the hole wall, prolonging the collision time. Moreover, this kind of gradually changing honeycomb aperture can effectively alleviate stress concentration and improve the overall buffering effect.
