Problems solved by technology

[0008] In view of this, the purpose of the present invention is to provide a fuel tank assembly and a vehicle to relieve the existing fuel tank from being connected to the vehicle body only through cable ties, and there is no collision buffer between the fuel tank and the vehicle body. The technical problem that the fuel tank is easy to fall off, deform and be punctured

Embodiment 1

[0038] like figure 1 and figure 2 As shown, the fuel tank assembly provided by the embodiment of the present invention includes: a fuel tank body 1 and a cable tie 2 suspended from the fuel tank body 1, and is characterized in that both ends of the cable tie 2 are fixedly connected to the vehicle body along the traveling direction of the vehicle body A flexible device is arranged between the fuel tank body 1 and the vehicle body, and the flexible device abuts against the side wall of the fuel tank body 1 facing the traveling direction of the vehicle body, and / or, the side wall facing away from the traveling direction of the vehicle body. Wherein, both ends of the cable tie 2 are fixedly connected to the lower end of the vehicle body, and the fuel tank body 1 is located between the cable tie 2 and the vehicle body. When car body collision and speed change are considered, the force between the fuel tank body 1 and the car body is generally distributed along the longitudinal di...

Embodiment 2

[0055] The vehicle provided by the embodiment of the present invention includes: the fuel tank assembly provided by the first embodiment. Since the technical effect of the vehicle provided in this embodiment is the same as that of the fuel tank assembly provided in Embodiment 1, it will not be repeated here.

Abstract

The invention provides a fuel tank assembly and a vehicle, and relates to the technical field of motor vehicles. The fuel tank assembly comprises a fuel tank body and a cable tie suspended on the fueltank body, both ends of the cable tie are fixedly connected with a vehicle body in the traveling direction of the vehicle body, a flexible device is disposed between the fuel tank body and the vehicle body, the flexible device abuts against the side wall, facing the traveling direction of the vehicle body, of the fuel tank body and / or the side wall facing away from the traveling direction of thevehicle body, the direct collision and extrusion between the fuel tank body and the vehicle body can be eliminated, which can greatly reduce the plastic strain and the cable tie stress of the fuel tank body during the collision, when the vehicle body is under collision, thereby ensuring the collision safety of the fuel tank assembly, and the service life of the cable tie and the safety performanceof the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicles, in particular to a fuel tank assembly and a vehicle. Background technique [0002] As automobile safety is getting more and more attention, the national new car evaluation norms and related laws and regulations are becoming more and more strict. The fuel tank is an indestructible part in the collision process, and it is extremely important in the safety of automobile collisions. The consequences such as leakage and fire are unimaginable, and Due to the dense arrangement of the fuel tank itself and its surrounding pipelines, installation wiring harness, etc., it also brings difficulties to the safety protection of the fuel tank collision. The 2018 version of the China New Car Evaluation Regulations (C-NCAP) clearly stipulates that: in the traditional three major collision forms tests (50kph frontal 100% overlapping rigid barrier collision, 64kph frontal 40% overlapping deformable barrier co...
