Description

Technical Field

[0001] This utility model relates to the automotive field, and more specifically, to a bumper. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for vehicle safety performance, the structural design and material selection of bumpers, as an important component of the car body, are particularly important. Nowadays, with the continuous updating of materials, aluminum alloy is usually chosen as the material for making bumpers in order to reduce weight while maintaining high strength.

[0003] To increase structural strength, typical aluminum alloy bumpers incorporate a honeycomb structure within the bumper. This structure effectively absorbs and disperses impact forces during frontal collisions. However, when a car travels on uneven roads, the shock-absorbing devices between the vehicle body and the road cause the vehicle to move vertically relative to the ground. The bumpy vehicle may then collide with solid, blunt objects such as stones. This structure struggles to withstand vertical and diagonal impacts.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength aluminum alloy bumper for automobiles.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes two bumper shells, the surface of the bumper shells is provided with through holes running from front to back, the inner wall of the holes is fixedly connected with a number of horizontally arranged and vertically arranged grilles, the inner wall of the bumper shells is fixedly connected with a number of vertically arranged pillars, the pillars are hexagonal structures, the upper end of the bumper shells is fixedly connected with an upper baffle, and the lower end of the bumper shells is fixedly connected with a lower baffle.

[0007] By adopting the above technical solution, this device is an aluminum alloy automotive bumper, mainly composed of a bumper shell and several grilles installed at the center of the bumper shell. The grilles are mainly used to protect the vehicle's cooling system and airflow in the engine compartment. The grilles can prevent debris, such as dust and small stones, from entering the engine compartment, thereby avoiding damage to the engine and other critical components. Several support pillars are fixedly connected inside the bumper shell. The support pillars are hexagonal structures. Hexagons are a structure with extremely high stability because their shape and structure can balance internal forces to the maximum extent and reduce structural twisting and deformation. Upper and lower baffles are installed at the top and bottom of the bumper shell, respectively. The hexagonal support pillars can effectively resist, but their ability to withstand pressure in the diagonal upward and downward directions is greatly reduced. Therefore, the upper and lower baffles bear the impact force or pressure received at the top and bottom of the bumper shell.

[0008] The present invention is further configured such that both the upper and lower stop bars are internally equipped with several hexagonal support columns.

[0009] By adopting the above technical solution, the upper baffle uses a hexagonal support to bear the impact force received at the top, and the lower baffle uses a hexagonal support to bear the impact force received at the bottom.

[0010] The present invention is further configured such that the support column is a hollow tube.

[0011] By adopting the above technical solution, the hollow structure significantly reduces the overall weight of the bumper because it is hollow inside. When a collision occurs, the hollow structure can effectively absorb and disperse the impact force. Its structural design allows each unit to deform when impacted, thereby absorbing a large amount of energy and saving materials during the manufacturing process.

[0012] The present invention is further configured such that the hexagonal support column is a solid hexagonal column.

[0013] By adopting the above technical solutions, in vehicle collision accidents, the upper and lower parts of the bumper are often the first parts to come into contact with the colliding object. They can effectively absorb and disperse the impact force generated during the collision, reducing the risk of injury to the vehicle and passengers. In addition to absorbing energy and buffering, the upper and lower parts of the bumper also need to provide stable support for the vehicle. The solid structure, due to its sturdiness, can ensure that the bumper maintains a stable posture when the vehicle is driving and parked, preventing deformation or displacement caused by external forces.

[0014] The present invention is further configured such that the pillars are arranged in an alternating pattern.

[0015] By adopting the above technical solutions, the staggered structure can more effectively disperse and absorb external forces. Since each unit is closely connected to the surrounding units, this structural form can maintain the stability of the overall structure when subjected to external forces, reducing the risk of deformation and damage.

[0016] The present invention is further configured such that the angle at which the two sides of the bumper housing fold backward is 120 degrees.

[0017] By adopting the above technical solution, when a vehicle collides at a certain angle, the angled rear bumper design can more effectively absorb and disperse the impact force. This design allows the bumper to better adapt to collisions at different angles, reducing damage to the vehicle structure and passengers. In particular, when a vehicle is involved in a side or oblique collision, the 120-degree angled rearward angle can better disperse the impact force, reducing the direct impact of the impact force on the side of the vehicle.

[0018] In summary, this utility model has the following beneficial effects: by installing upper and lower baffles at the upper and lower ends of the bumper housing, the impact force from the bumper in the upward or downward direction is distributed. The solid hexagonal columns installed inside the upper and lower baffles distribute the damage caused by the impact, reducing damage to the vehicle. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0023] A type of high-strength aluminum alloy bumper for automobiles, such as Figure 1 As shown, a high-strength aluminum alloy bumper for automobiles includes a bumper housing 1, a plurality of grilles 11 fixedly connected to the center of the bumper housing 1, a plurality of pillars 12 fixedly connected inside the bumper housing 1, the pillars 12 having a hexagonal structure, an upper baffle 2 installed at the upper end of the bumper housing 1, a lower baffle 3 installed at the lower end of the bumper housing 1, and the angle at which the two sides of the bumper housing 1 fold backward is 120 degrees.

[0024] like Figure 2As shown, both the upper baffle 2 and the lower baffle 3 have several hexagonal support columns 21 installed inside. The support column 12 is a hollow tube, and the hexagonal support column 21 is a solid hexagonal column. The support columns 12 are arranged alternately.

[0025] This device is an aluminum alloy automotive bumper, mainly composed of a bumper housing 1 and several grilles 11 installed at the center of the bumper housing 1. The grilles 11 are mainly used to protect the vehicle's cooling system and airflow in the engine compartment. The grilles 11 can prevent debris, such as dust and small stones, from entering the engine compartment, thereby avoiding damage to the engine and other critical components. Several support pillars 12 are fixedly connected inside the bumper housing 1. The support pillars 12 have a hexagonal structure, which can maximize the balance of internal forces and reduce structural twisting and deformation. The support pillars 12 are hollow, which can save materials during the manufacturing process. In the event of a collision, the hollow structure can effectively absorb and disperse the impact force. Its structural design allows each unit to withstand the impact. The deformation during impact ensures the bumper maintains a stable posture when the vehicle is in motion or parked, preventing deformation or displacement caused by external forces. The staggered arrangement of the pillars 12 can more effectively disperse and absorb external forces. The hexagonal pillars 12 can effectively resist, but their ability to withstand pressure in the diagonal upward and downward directions is greatly reduced. Therefore, upper baffles 2 and lower baffles 3 are installed at the upper and lower ends of the bumper shell 1, respectively. The upper baffles 2 and lower baffles 3 bear the impact force or pressure received at the upper and lower ends of the bumper shell 1. The hexagonal pillars 21 installed inside the upper baffles 2 and lower baffles 3 are solid. Due to their sturdiness, the solid structure can effectively absorb and disperse the impact force generated during a collision.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
