Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an automotive front bumper assembly. Background Technology
[0002] Car bumpers are a primary safety component of the vehicle body, playing a crucial role in protecting the safety of drivers and occupants during a collision. Therefore, car bumpers have always been a key focus in vehicle crashworthiness design. Bumpers are installed at both the front and rear of a car, and with societal development and the increasing prevalence of automobiles, the safety and protective functions of bumpers are receiving increasing attention.
[0003] Currently, car bumpers can act as a buffer in the event of a collision, protecting the front and rear of the vehicle. However, their energy absorption effect is poor, and their protective function is also relatively weak. Utility Model Content
[0004] The purpose of this utility model is to provide a front bumper assembly for automobiles to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A front bumper assembly for automobiles includes a bumper body, an mounting groove is provided on the inner side of the bumper body, an airbag is installed in the mounting groove, a baffle is provided on one side of the airbag, side plates are connected to both ends of the bumper body through multiple buffer support members distributed at equal intervals, a protective sleeve is provided between two side plates, an anti-collision steel frame is installed inside the protective sleeve, and the protective sleeve and the baffle are connected by multiple arc-shaped spring pieces distributed at equal intervals.
[0006] Preferably, the bumper body has a U-shaped structure.
[0007] Preferably, an inflation nozzle is provided on one side of the upper surface of the airbag.
[0008] Preferably, the buffer support includes a slide rod, on which a spring is sleeved, and one end of the slide rod is fixedly connected to the side plate.
[0009] Preferably, the two end sidewalls of the bumper body are provided with a plurality of sliding cavities corresponding to the sliding rods, the end of the sliding rods extends into the inner cavity of the sliding cavity and is slidably connected thereto, and the two ends of the springs are respectively connected to the bumper body and the side plate.
[0010] Preferably, the two ends of the baffle are fixedly connected to the inner walls of both sides of the bumper body.
[0011] The automotive front bumper assembly of this utility model has the following advantages:
[0012] When a car collides, this invention causes the bumper body to deform, and the airbag to deform as well, absorbing some of the energy. Simultaneously, the bumper body exerts pressure on the spring, which in turn dissipates some of the impact force, achieving a shock absorption and cushioning effect. Furthermore, the baffle exerts pressure on the arc-shaped spring, causing it to deform to both sides, thus changing the direction of the impact force and further improving the shock absorption and cushioning effect. Therefore, this car bumper assembly achieves a three-level cushioning protection effect, exhibiting excellent impact resistance and providing effective energy absorption, shock absorption, and protection, resulting in high safety.

[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a front bumper assembly for automobiles.
[0025] like Figure 1-4As shown, this utility model discloses a front bumper assembly for automobiles, including a bumper body 1. The bumper body 1 has a U-shaped structure, and an mounting groove 10 is provided on the inner side of the bumper body 1. An airbag 2 is installed in the mounting groove 10, and a baffle 3 is provided on one side of the airbag 2. To prevent excessive cushioning pressure from damaging the internal structure of the automobile, a maximum threshold should be designed in the structure of the airbag 2. When the pressure exceeds this threshold, the airbag 2 will rupture and deflate, effectively reducing the cushioning pressure. When a collision occurs, the sealed airbag mounted on the bumper will deform, increasing the air pressure inside the airbag and preventing further deformation. The greater the energy of the collision, the greater the deformation of the sealed airbag and the greater the increase in air pressure inside. Unless the energy and intensity of the impact are extremely high, causing the air pressure inside the sealed airbag to increase to the point that the airbag cannot withstand it and ruptures, the sealed airbag can absorb energy during a collision through its own deformation and the increase in air pressure inside, thereby reducing damage to the automobile and protecting the safety of the driver and passengers. If the airbag is made of a highly malleable non-metallic material such as rubber, it can quickly return to its original shape under internal pressure after a crash. However, if the airbag is made of metallic materials such as stainless steel or carbon steel, it is difficult for it to return to its original shape under the influence of internal forces after a crash. Furthermore, using high-quality composite rubber and polymer materials increases the elasticity of the inflatable airbag, improves its anti-aging and wear resistance, and enhances its sealing performance. Therefore, the surface of airbag 2 is made of high-quality composite rubber material. An inflation nozzle 4 is located on one side of the upper surface of airbag 2, allowing for inflation of airbag 2.
[0026] The bumper body 1 has side plates 5 connected to both ends by multiple equally spaced buffer support members 6. A protective sleeve 7 is provided between the two side plates 5, and an anti-collision steel frame 8 is installed inside the protective sleeve 7. The protective sleeve 7 is connected to the baffle 3 by multiple equally spaced arc-shaped spring pieces 9. The two ends of the baffle 3 are fixedly connected to the inner walls of both sides of the bumper body 1. The buffer support 6 includes a slide rod 12, on which a spring 13 is sleeved. One end of the slide rod 12 is fixedly connected to the side plate 5. Both ends of the bumper body 1 have multiple sliding cavities 11 that correspond one-to-one with the slide rod 12. The end of the slide rod 12 extends into the inner cavity of the sliding cavity 11 and is slidably connected to it. Both ends of the spring 13 are respectively connected to the bumper body 1 and the side plate 5. Through the cooperation between the slide rod 12, the spring 13 and the sliding cavity 11, when the bumper body 1 is impacted, it will move towards the side plate 5, thereby causing the bumper body 1 to compress the spring 13. The spring 13 then dissipates part of the impact force, achieving a shock absorption effect.
[0027] The working principle of this automotive front bumper assembly is as follows: When a collision occurs, the bumper body 1 deforms, and the airbag 2 deforms to absorb some of the energy. At the same time, the bumper body 1 exerts a compressive force on the spring 13, which dissipates some of the impact force, achieving a shock absorption and buffering effect. In addition, the baffle 3 exerts a compressive force on the arc-shaped spring 9, which deforms to both sides to change the direction of the impact force, further improving the shock absorption and buffering effect. Thus, the automotive bumper assembly achieves a three-level buffer protection effect, has good impact resistance, and plays a good role in energy absorption, shock absorption, and protection, resulting in strong safety.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
