Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a front bumper inner reinforcement assembly. Background Technology

[0002] The front bumper, also known as a front bumper beam, is an important component of a car's safety system and is typically installed at the front of the vehicle. It absorbs energy during a collision, reducing injury to the vehicle body and occupants, thus improving vehicle safety and is one of the key components in a car's passive safety design.

[0003] The utility model patent with patent number CN222097590U discloses a front bumper beam connection structure and a front bumper beam, which include the following:

[0004] The front bumper beam connection structure and the front bumper beam itself lack an independent initial buffer structure during light impacts, which easily leads to direct deformation of the front bumper beam under stress and low energy absorption efficiency. At the same time, the bumper beam is a single hollow structure, which is easily crushed in one go under heavy impacts, and it lacks longitudinal protection and cannot effectively disperse lateral impact forces. In view of this, we propose a front bumper beam internal reinforcement assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a front bumper internal reinforcement assembly to solve the problems mentioned in the background art, such as the lack of an independent initial buffer structure, easy crushing under heavy impact, and lack of longitudinal protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A front bumper reinforcement assembly includes a main body, a light impact protection component for initial energy absorption is provided on the outer side of the main body, a crumple zone component for further energy absorption is provided on the inner side of the main body, and a vertical protection component for increasing the protection range is also provided on the main body. The light impact protection component includes a corrugated plate with a gap between the corrugated plate and the front end face of the main body. The crumple zone component includes a sleeve beam fitted inside the main body and several crumple blocks fixed inside the sleeve beam. The vertical protection component includes several curved plates symmetrically fixed on the top and bottom sides of the main body and two protective tubes symmetrically distributed on the top and bottom sides of the main body. The protective tubes are fixedly connected to the curved plates.

[0008] Preferably, the cross-section of the main rod is U-shaped with the opening facing backward, and a pair of connecting posts are fixed inside the main rod, with the rear end of the connecting posts connected to the vehicle body;

[0009] In this configuration, the U-shaped structure of the main rod provides installation space for internal components, and the connecting column ensures a stable connection with the vehicle body.

[0010] Preferably, a plurality of connecting plates are fixed on the rear surface of the corrugated plate, and the rear ends of the connecting plates are tightly welded to the front end surface of the main rod.

[0011] In this configuration, the connecting plate securely connects the corrugated plate to the main rod, enabling the corrugated plate to effectively absorb energy during minor impacts.

[0012] Preferably, the cross-section of the sleeve beam is U-shaped with an opening facing forward, and the front end of the sleeve beam is provided with a sleeve cavity, in which a reinforcing rib plate is fixed, and the reinforcing rib plate is in a horizontal state within the sleeve cavity;

[0013] In this configuration, the sleeve beam and the main rod form a double protection, and the reinforcing ribs enhance the strength of the sleeve cavity.

[0014] Preferably, the collapse block has a hollow cuboid structure, and a plurality of the collapse blocks are separated by the reinforcing rib in the vertical direction. The plurality of the collapse blocks are arranged at equal intervals along the length of the cavity in the horizontal direction, and a gap is left between two horizontally adjacent collapse blocks.

[0015] In this setup, the hollow cuboid collapse blocks are easily deformed to absorb energy, and the arrangement with equal spacing and gaps achieves gradual energy absorption.

[0016] Preferably, the end of the bent plate has an arc-shaped plate structure, and the beginning of the bent plate is fixed with a seat plate, which is tightly welded to the main rod body;

[0017] In this setup, the curved end of the bend plate adapts to the shape of the vehicle body, and the seat plate ensures a secure connection between the bend plate and the main rod.

[0018] Preferably, the protective tube is fixed to the front side of the bent plate, and a connecting rod is fixed between the first and last ends of the two protective tubes;

[0019] In this configuration, the connecting rod links the two protective tubes together, improving the structural stability of the longitudinal protective assembly.

[0020] Preferably, a pair of longitudinal stiffeners are fixed between the rear end faces of the two bent plates in the vertical direction, and a longitudinal connecting pipe is sandwiched between the two longitudinal stiffeners. The top and bottom ends of the longitudinal connecting pipe are respectively fixedly connected to the rear end faces of the two bent plates.

[0021] In this configuration, longitudinal stiffeners and longitudinal connecting tubes enhance the strength and stability of the longitudinal protection components, improving their ability to disperse impact forces.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. The front bumper internal reinforcement assembly, by setting a light protection component, creates a buffer gap between the corrugated plate and the main body. In the event of a light impact, the wave-shaped structure of the corrugated plate can first absorb energy through elastic deformation, reducing the direct force on the main body and improving the buffering effect of the initial impact.

[0024] 2. The front bumper internal reinforcement assembly, through the set crumple zone components, enables the sleeve beam and crumple block to cooperate to achieve graded energy absorption. The U-shaped structure of the sleeve beam and the hollow cuboid design of the crumple block can produce progressive folding deformation during heavy impact, achieving a further energy absorption effect. At the same time, the set vertical protection components make the curved plate and protective tube form a three-dimensional protective structure, which can effectively disperse the impact force, expand the protection range, and reduce the impact on the vehicle body.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5 A front bumper internal reinforcement assembly includes a main rod 100, the cross-section of which is U-shaped with an opening to the rear. A pair of connecting posts 110 are fixed inside the main rod 100, and the rear end of the connecting posts 110 is connected to the vehicle body. The U-shaped structure of the main rod 100 can provide installation space for internal components, while the connecting posts 110 achieve a stable connection with the vehicle body.

[0037] like Figures 1-3 As shown, in this utility model, a light impact protection component 200 for initial energy absorption is provided on the outer side of the main rod 100. The light impact protection component 200 includes a wave-shaped corrugated plate 210. A gap is left between the corrugated plate 210 and the front end face of the main rod 100. Several connecting plates 220 are fixed on the rear surface of the corrugated plate 210. The rear end of the connecting plates 220 is tightly welded to the front end face of the main rod 100. The wave-shaped structure of the corrugated plate 210 can absorb energy through elastic deformation during light impact. The gap between it and the main rod 100 forms a buffer space, further improving the energy absorption effect. The connecting plates 220 ensure a stable connection between the corrugated plate 210 and the main rod 100.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, specifically, a further energy-absorbing crumple assembly 300 is provided on the inner side of the main rod 100. The crumple assembly 300 includes a sleeve beam 310 sleeved on the inner side of the main rod 100 and several crumple blocks 320 fixed inside the sleeve beam 310. The cross-section of the sleeve beam 310 is U-shaped with an opening facing forward. The front end of the sleeve beam 310 is provided with a cavity 311. A reinforcing rib plate 312 is fixed in the cavity 311. The reinforcing rib plate 312 is in a horizontal state inside the cavity 311. The sleeve beam 310 is sleeved on the inner side of the main rod 100, forming a double protection structure with the main rod 100. The crumple blocks 320 can absorb energy through deformation during heavy impact, and the reinforcing rib plate 312 can enhance the structural strength of the cavity 311.

[0039] like Figure 4As shown, the collapse block 320 further has a hollow cuboid structure. Several collapse blocks 320 are separated by reinforcing ribs 312 in the vertical direction, and several collapse blocks 320 are arranged at equal intervals along the length of the cavity 311 in the horizontal direction. There is a gap between two horizontally adjacent collapse blocks 320. The hollow cuboid structure makes the collapse blocks 320 more likely to deform when subjected to impact force, thereby absorbing energy. The design of equal intervals and gaps allows the collapse blocks 320 to deform in an orderly manner and achieve gradual energy absorption.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, in addition, the main pole 100 is also provided with a vertical protection component 400 to increase the protection range. The vertical protection component 400 includes several curved plates 410 symmetrically fixed on the top and bottom sides of the main pole 100 and two protective tubes 420 symmetrically distributed on the top and bottom sides of the main pole 100. The protective tubes 420 are fixedly connected to the curved plates 410. The vertical protection component 400 can increase the longitudinal protection range of the main pole 100. The curved plates 410 and the protective tubes 420 work together to effectively disperse the lateral impact force and reduce the impact of the impact on the sides of the vehicle body.

[0041] like Figure 5 As shown, it is worth noting that the end of the curved plate 410 has an arc-shaped plate structure, and the beginning of the curved plate 410 is fixed with a seat plate 411, which is tightly welded to the main rod 100. The protective tube 420 is fixed to the front side of the curved plate 410, and a connecting rod 421 is fixed between the beginning and end of the two protective tubes 420. The arc-shaped end of the curved plate 410 can better adapt to the shape of the vehicle body and enhance the protective effect. The seat plate 411 ensures a firm connection between the curved plate 410 and the main rod 100, and the connecting rod 421 connects the two protective tubes 420 into a whole, improving the structural stability of the vertical protective assembly 400.

[0042] like Figure 5 As shown, it is worth noting that a pair of longitudinal stiffeners 430 are fixed between the rear end faces of the two curved plates 410 in the vertical direction, and a longitudinal connecting pipe 440 is sandwiched between the two longitudinal stiffeners 430. The top and bottom ends of the longitudinal connecting pipe 440 are fixedly connected to the rear end faces of the two curved plates 410, respectively. The longitudinal stiffeners 430 and the longitudinal connecting pipe 440 further enhance the structural strength and stability of the vertical protection component 400, enabling the entire vertical protection component 400 to better withstand and disperse impact forces.

[0043] In this embodiment, when the front bumper reinforcement assembly is in use, firstly, in the event of a minor impact, the impact force acts on the corrugated plate 210 of the minor impact protection component 200. The wave-shaped structure of the corrugated plate 210 undergoes elastic deformation, and the gap between it and the main body 100 forms a buffer, absorbing part of the impact energy and deforming to reduce the impact force on the main body 100. Then, if the impact force is larger, the energy is transferred to the main body 100, and the U-shaped structure of the main body 100 and the connecting column 110 will absorb part of the energy. The impact is transmitted to the vehicle body, and the crumple zone 300 starts to work. The sleeve beam 310 and the crumple block 320 absorb energy through deformation, and the reinforcing rib 312 ensures that the crumple block 320 deforms in an orderly manner. Then, when the impact force involves the upper and lower sides of the main body 100, the bending plate 410, the protective tube 420, the longitudinal rib 430 and the longitudinal connecting tube 440 of the vertical protection component 400 work together to disperse the impact force and expand the protection range. Finally, through the synergistic effect of the components, the damage to the vehicle body and the occupants from the impact is reduced.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
