[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application.

[0032] Embodiment 1 of the present application refers to Figures 1-5 As shown in the drawings, an automatic driving vehicle bumper is disclosed, which comprises two groups of anti-collision supports 1, a connecting beam 2, a top frame 3 and a bottom frame 4. The anti-collision support 1 comprises a support longitudinal beam 11, a support transverse beam 12, a support side beam 13 and a support rib 14. The support transverse beam 12, the support side beam 13 and the support rib 14 form a rectangular cavity 15. The rectangular cavity 15 is used to provide a forward support force for the support longitudinal beam 11 and provide additional support force for the support longitudinal beam 11. The connecting beam 2 is connected between the support longitudinal beams 11 of the two groups of anti-collision supports 1, which enhances the overall structural strength of the bumper. The top frame 3 is wrapped above the two groups of anti-collision supports 1, and the bottom frame 4 is wrapped below the two groups of anti-collision supports 1. This design makes the bumper more effectively disperse and absorb impact force when it is impacted, reduces the deformation of the vehicle itself, and the top frame 3 and the bottom frame 4 not only further enhance the overall strength of the bumper, but also provide an additional protective layer.

[0033] In some embodiments, the support cross beam 12 comprises an integrally bent cross beam body surface 121, a cross beam top surface 122 and a cross beam side surface 123; the front side of the cross beam body surface 121 is provided with a cross beam abutting surface 124 which abuts against the support longitudinal beam 11. The integrally bent structure not only enhances the structural strength of the cross beam, but also enables the cross beam to better disperse and absorb impact force when impacted. The cross beam top surface 122 and the cross beam side surface 123 together enclose a relatively closed space which provides additional support and protection for the cross beam body surface 121. When impacted, the cross beam top surface 122 and the cross beam side surface 123 can work together to prevent the cross beam body surface 121 from being excessively squeezed and deformed. Preferably, the support rib 14 comprises an integrally bent support bottom plate 141, a first support rib abutting surface 142 and a second support rib abutting surface 143, the rectangular cavity 15 is enclosed by the support bottom plate 141, the cross beam top surface 122, the cross beam side surface 123 and the support side beam 13, the first support rib abutting surface 142 is connected with the support side beam 13, and the second support rib abutting surface 143 is connected with the cross beam side surface 123. By such arrangement, the rigidity and stability of the support rib 14 are improved, and the support rib 14 can better transmit and disperse impact force when impacted.

[0034] In some embodiments, the support longitudinal beam 11 comprises an integrally bent longitudinal beam body 111, a first longitudinal beam abutting surface 112 and a second longitudinal beam abutting surface 113, the first longitudinal beam abutting surface 112 is connected with the top frame 3 and the bottom frame 4, and the second longitudinal beam abutting surface 113 is connected with the support rib 14. The connection of the first longitudinal beam abutting surface 112 with the top frame 3 and the bottom frame 4 ensures the stability of the bumper in the vertical direction, so that the bumper can more effectively disperse and transmit impact force when impacted from the front and above, thereby protecting the vehicle from damage. Preferably, the longitudinal beam body 111 is provided with a plurality of weight-reducing holes 114 which are in a triangular structure. The design of the weight-reducing holes 114 significantly reduces the weight of the longitudinal beam body 111, thereby helping to reduce the weight of the entire bumper and even the vehicle, which not only improves the electrical energy utilization efficiency of the vehicle and reduces the operating cost, but also helps to reduce carbon emissions and conforms to the current environmental protection trend of energy saving and emission reduction. Although the weight-reducing holes 114 reduce the use of materials, the triangular structure of the weight-reducing holes 114 has excellent stability in mechanics. This design can achieve effective weight reduction while ensuring structural strength. The triangular structure can disperse and resist pressure from all directions, ensuring that the bumper still has sufficient strength and rigidity when impacted.

[0035] In some embodiments, the top frame 3 includes a top main frame 31, a first top side frame 32 and a second top side frame 33 connected to both sides of the top main frame 31 respectively, and two groups of the anti-collision supports 1 abut against the first top side frame 32 and the second top side frame 33 respectively. The bottom frame 4 includes a bottom main frame 41, a first bottom side frame 42 and a second bottom side frame 43 connected to both sides of the bottom main frame 41 respectively, and two groups of the anti-collision supports 1 abut against the first bottom side frame 42 and the second bottom side frame 43 respectively. Preferably, the first top side frame 32 and the second top side frame 33 are inclined to the rear side, and the first bottom side frame 42 and the second bottom side frame 43 are inclined to the rear side. The side frames of the top frame 3 and the bottom frame 4 are inclined to the rear side, forming a triangular support structure with the anti-collision supports 1. This design is very stable in mechanics, can effectively disperse and absorb impact force from all directions, and enhances the overall structural stability of the bumper. At the same time, it can maintain the streamline design of the vehicle body.

[0036] Optionally, in some embodiments, a forwardly protruding annular anti-collision rib 5 can also be provided on the bottom main frame 41. The design of the annular anti-collision rib 5 increases the strength and rigidity of the bottom main frame 41, so that it can better resist deformation and damage when impacted. This design helps to protect important components at the bottom of the vehicle.

[0037] Optionally, in some embodiments, a spare trailer device 6 is provided on the connecting beam 2, and the annular anti-collision rib 5 is arranged in front of the trailer device 6, so that the hook of the spare trailer device 6 can rotate to extend or retract.

[0038] In summary, the bumper for an autonomous vehicle provided by the present application has the following technical effects:

[0039] 1. By designing the support cross beam 12, the support side beam 13 and the support rib 14 to enclose a rectangular cavity 15, this structure effectively provides additional support force for the support longitudinal beam 11. This design makes the bumper more effectively disperse and absorb impact force when impacted, significantly improving its structural strength and stability. At the same time, the arrangement of the connecting beam 2 further enhances the overall structure of the bumper, so that it can maintain good integrity and functionality when dealing with various impact situations;

[0040] 2. The rectangular cavity 15 structure inside the bumper and the reinforcing design of the connecting beam 2, the top frame 3 and the bottom frame 4 together form an efficient energy absorption and dispersion system. When a vehicle is involved in a collision, these structures can work together to disperse impact force to a wider area, reducing structural damage caused by excessive local stress. This design helps to protect the vehicle itself and reduces damage to the vehicle body;

[0041] 3. The addition of the top frame 3 and the bottom frame 4 not only further enhances the overall strength of the bumper, but also provides an additional layer of protection for the vehicle. These frames are able to more effectively withstand impacts from above and below, protecting critical components of the vehicle from damage;

[0042] 4. The high-strength material and optimized structural design allow for better integrity and functionality after being subjected to impacts. This helps to reduce the cost of repairs and replacements for the vehicle, improving its efficiency and economy.
