Description
Technical Field
The invention relates to the technical field of vehicle protection devices, in particular to a vehicle and a fuel container protection frame structure thereof.
Background
The fuel tank in the vehicle is used as a fuel container, the fuel is loaded in the fuel tank as a vehicle power source, the fuel has higher heat value, and can release a large amount of energy to drive the engine to act after combustion, if the fuel tank leaks or is damaged due to external impact, the fuel in the fuel tank is easy to leak to the outside to burn or even explode, and the driving safety is seriously affected.
In the prior art, a technician can set a protective structure at the fuel tank to ensure the safety of the fuel tank; in the current regulations, it is required that the fuel tank in a vehicle is not less than 600mm from the front end of the vehicle (for a commercial passenger car with a rear engine, the front end face of the fuel tank should be located behind the front axle) and not less than 300m from the rear end of the vehicle, so that a passenger car manufacturer mostly disposes the fuel tank in the middle of the front and rear wheels, and because of the need for convenience of operation (the distance between the fuel filler opening on the side of the vehicle body and the fuel tank opening), technicians mostly will then dispose closer to the side wall, which structure enables the fuel tank to be protected by the vehicle body structure when being collided from the front and rear sides of the vehicle, but does not enable the fuel tank to be protected by the side face.
The application publication number is CN104859432A, the application publication date is 2015.08.26's chinese patent discloses a passenger car oil tank side collision protection structure, wherein including the base assembly that is used for bearing the weight of the oil tank and the welding is used for protecting the guard frame assembly of oil tank on the base assembly, and be fixed in the slide rail on the automobile body, the base assembly is the square underframe that is welded by supporting beam, and parallel arrangement has square roof-frame on square underframe, be equipped with between square roof-frame and square underframe and support underframe, four stands as supporting beam, the opposite side face that is used for installing the crashproof roof beam between every two adjacent stands has been formed, and square roof-frame and stand have formed the guard frame assembly that protects the oil tank, the welding has the reinforcing rectangular pipe that is X type cross as crashproof roof beam on its corresponding opposite faces respectively on the front of guard frame assembly, after, left and right four facades.
The intensity that these crisscross reinforcing rectangular pipes formed is higher, can receive the impact force that will receive when the oil tank side receives the collision through crisscross rectangular nest of tubes with its outside transmission, prevent that the oil tank from receiving direct striking, guaranteed the safety of oil tank, but after these reinforcing rectangular pipes are by collision deformation, because the seal structure of welding, can't dismantle the change to rectangular pipe, perhaps the rectangular pipe on a facade bumps deformation, can only change whole guard frame assembly, and maintenance is inconvenient for whole protective structure's maintenance.
Chinese patent publication number CN201410988Y, publication date 2010.2.24 discloses a truck fuel tank protection device comprising a bracket and a protection cross beam connected to the bracket as an anti-collision beam. The support comprises a set of left and right support that set up relatively, and the protection crossbeam is connected about between the support to the cross section of protection crossbeam is the cell type structure, cooperates with the turn-ups that set up on controlling two supports, and can all be provided with four bolts and carry out the spiro union in order to form the protection frame assembly that protects the fuel tank in turn-ups department every limit. But the problem that exists is that every limit of crashproof roof beam is connected with four bolts, and a large number is inconvenient for technicians to dismantle to the bolt is not directly fixed on crashproof roof beam, but relies on crashproof roof beam's turn-ups to fix on the support, offers more and bolt complex hole on the support, makes its self intensity decline, and the bolt that the spiro union is more on the side of the turn-ups complex of support and crashproof roof beam can make the support produce stress concentration's problem.
