Description

New forms of energy four-wheel vehicle bumper Technical Field The utility model relates to the technical field of vehicle accessories, in particular to a new energy four-wheel vehicle bumper. Background The new energy four-wheel vehicle gradually occupies the main stream of market development due to the advantages of energy conservation, environmental protection, low emission and the like, meanwhile, the safety performance of the vehicle, particularly the collision safety, is taken as an important component of the passive safety system of the automobile, and the main function of the bumper is to reduce the damage of the collision to the vehicle body structure and passengers in the vehicle by absorbing and dispersing the collision energy. The bumper of traditional fuel car adopts steel or combined material structure generally, cooperates parts such as bumper and energy-absorbing box to realize energy absorption, but in actual collision process, current bumper is because its structural rigidity is great, often appears instantaneous global deformation when receiving great impact, and the energy-absorbing process is inhomogeneous, leads to energy transmission and dispersion effect limited, under this kind of circumstances, powerful impact is easily transmitted to automobile body longeron even cockpit through the bumper, increase driver and passenger's injury risk, for new energy automobile, vehicle structure and driving system overall arrangement are different than traditional car, for example, partial group battery sets up near chassis or front and back axle, this has put forward higher requirement to anticollision safety. However, in the prior art, the new energy four-wheel vehicle bumper generally uses the traditional design thought, lacks the pertinence optimization, is difficult to effectively control the deformation of the bumper when suffering from collision, is easy to locally break or wholly fail, cannot fully exert the buffering and energy absorbing effects, and can directly transmit the impact force to one side of a driver due to overlarge rigidity to cause secondary injury. Disclosure of utility model The utility model provides a new energy four-wheel vehicle bumper, which aims to solve the problem of the adaptation of the new energy four-wheel vehicle and the bumper and improve the protection capability of the bumper. The novel energy four-wheel vehicle bumper provided by the utility model adopts the following technical scheme: The utility model provides a new forms of energy four-wheel vehicle bumper, includes the bumper assembly, the bumper assembly is installed at vehicle front end and/or rear end, set up and be connected with damper on the bumper assembly, the outside parcel of bumper assembly has housing assembly, the bumper assembly is fixed connection each other with housing assembly, the bumper assembly is connected fixedly through assembly and frame and car shell. Through set up damper on the bumper assembly, can effectively absorb and disperse external impact energy when the vehicle receives the collision, show the risk that reduces the impact and directly transmit to body structure and passenger cabin, promote the passive security performance of whole car, damper's introduction makes the bumper can realize controllable deformation according to impact strength, evenly release collision energy, prevent to lead to because of local rigidity is too big whole inefficacy or secondary injury, effectively protect driver and passenger's life safety, this bumper assembly passes through assembly component and is reliably connected with frame and car shell, the stable structure can adapt to the special chassis overall arrangement of new energy vehicle and group battery and arrange the demand, the parcel has housing assembly outside the bumper assembly, effectively protect the bumper assembly from the rainwater erosion. Further, the bumper assembly includes the girder, the girder sets up along terminal surface level before the automobile body, the girder is hollow structure, be provided with at least one stiffening beam in the girder, be provided with the structural layer in the girder, the structural layer is filled in the space between girder wall and stiffening beam wall. The girder adopts hollow structure to set up at least one stiffening beam in inside, effectively promoted the bulk strength and the rigidity of bumper, when the collision takes place, stiffening beam can strengthen the bearing capacity of girder, prevent that the girder from taking place excessive deformation or fracture, thereby protect vehicle structure and passenger's safety better, the girder intussuseption is filled with the structural layer, this structural layer is located between girder wall and the stiffening beam wall, the structural layer adopts the material that energy-absorbing performance is excellent, can effectively absorb and disperse impact energy in the striking process, reduce the peak value of impact force, th
