DETAILED DESCRIPTION

[0017] The technical scheme in the embodiment of the utility model will be described clearly and completely in connection with the drawings in the embodiment of the utility model, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0018] One embodiment of the utility model, as shown in Figure 1 And Figure 2 The bumper assembly 1 includes the bumper main body 11 and the framework 12 and the crossbeam 13 embedded in the bumper main body 11, the energy absorption box 2 is installed in the side of crossbeam 13 close to car body 4, and the quick -connection structure 3 is arranged at the junction of energy absorption box 2 and car body 4, only need to replace the damaged parts after the collision, reduce the maintenance cost and time, honeycomb structure combines multistage energy absorption design, promotes the collision safety, and the modularization design adapts to different vehicle types, and reduces the spare parts variety, reduces the maintenance cost through detachable design, and improves energy absorption efficiency.

[0019] The quick-connect structure 3 includes a slide rail 32 connected to the vehicle body 4 and a locking structure. After a collision, the damaged module can be removed by sliding. The slide rail 32 is equipped with a vehicle body reinforcement 31 connected to the energy-absorbing box 2. Guide grooves 41 are provided on the vehicle body 4 on both sides of the slide rail 32 to ensure quick alignment and installation of the energy-absorbing box. The two ends of the vehicle body reinforcement 31 near the vehicle body 4 are provided with elastic claws 33. When the bumper is installed, the energy-absorbing box and the vehicle body reinforcement move along the slide rail. At the same time, the elastic claws are subjected to downward pressure from the vehicle body. After moving into place, the elastic claws reset and spring back to clamp the side of the vehicle body.

[0020] like Figure 3 As shown, the energy-absorbing box 2 is made of honeycomb aluminum or composite materials. The inside of the energy-absorbing box 2 is filled with compressible energy-absorbing foam. The energy-absorbing box 2 is connected to the crossbeam 13 by standardized buckles or bolts and can be disassembled and replaced separately. The hexagonal honeycomb aluminum has a large energy absorption capacity and a small peak impact force. The aluminum structure can reduce weight. At the same time, due to its good thermal conductivity, it can ensure that the energy is quickly conducted to the outside in the form of heat when absorbing energy, avoiding local overheating. In addition, the mechanical properties of aluminum can remain unchanged at low temperatures, effectively ensuring that it can still function normally in harsh climates.

[0021] The energy-absorbing box 2 includes a front module 21 and a rear module 23. The front module 21 and the rear module 23 are separated by an internal partition 22. The front module is a low-intensity collision energy-absorbing structure, and the rear module is a high-intensity collision energy-absorbing structure. The rear module 23 has a crumple guide groove 231 on its side to guide the energy-absorbing box to undergo collision compression deformation, thereby reducing the collision force in the initial stage of the collision. The front module 21 can be replaced separately, and the rear module 23 is integrated with the body reinforcement 31. After a collision, the damaged part of the front module can be directly repaired, reducing maintenance costs and time.

[0022] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships, and the relative positional relationships may change when the absolute position of the described objects changes. Second, in this document, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.

[0023] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
