Abstract
An embodiment of the invention provides an automotive rear frame assembly and an automobile applying the same, relates to automotive accessories, and solves the problem of low automotive safety due to the fact that an oil tank is prone to damage and leakage when an existing automotive rear frame assembly is subjected to rear collision. A reinforcing device is arranged and fixed on a spare tire cover to enable the spare tire cover to have a reinforcing area and a weakening area. The reinforcing area corresponds to an occupied area of the reinforcing device and an extension area of the reinforcing device facing a rear longitudinal beam, so that the reinforcing area is high in strength while the weakening area is low in strength. An oil tank is fixedly supported on the reinforcing device, corresponds to the reinforcing area in position and is close to the spare tire cover as being limited by automobile rear integral space to enable a gap between the oil tank and the spare tire cover to be small. After rear collision happens, the reinforcing area is high in strength while small in deformation, so that damage to the oil tank due to deformation of the reinforcing area is avoided, the weakening area of the spare tire cover deforms to absorb energy, the oil tank is protected effectively, and automobile safety is improved.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The automobile rear frame assembly that the embodiment of the present invention provides, the automobile rear frame assembly structural representation that Fig. 3 provides for the embodiment of the present invention, the automobile rear frame assembly simplified structure schematic diagram that Fig. 2 provides for the embodiment of the present invention.As shown in Figures 2 and 3, comprise two floor side members 21, spare wheel cover 22 and fuel tank 23, also comprise reinforcing device 24, reinforcing device 24 is fixed on spare wheel cover 22; Fuel tank 23 is fixedly supported on reinforcing device 24; Wherein, reinforcing device 24 is also for being divided into reinforcement district 221 and weakening region 222 by spare wheel cover 22; Reinforcement district 221 corresponds to region shared by reinforcing device 24 and reinforcing device 24 elongated area towards floor side member 21; Weakening region 222 is positioned at reinforcement district 221 periphery.
In the automobile rear frame assembly that the embodiment of the present invention provides, owing to being provided with reinforcing device, and reinforcing device is fixed on spare wheel cover, spare wheel cover is made to there is reinforcement district and weakening region, because reinforcement district corresponds to region shared by reinforcing device and the reinforcing device elongated area towards floor side member, make reinforcement district intensity larger, relative weakening region intensity is little, fuel tank is fixedly supported on reinforcing device, namely fuel tank position corresponds to reinforcement district, due to the restriction by automobile rear overall space, fuel tank is near spare wheel cover, make the spacing between fuel tank and spare wheel cover less, after touch generation time, the intensity large deformation of reinforcement district is small, thus avoid the damage of reinforcement district distortion to fuel tank, the weakening region distortion of spare wheel cover is made to absorb energy, effectively protect fuel tank, improve the safety of automobile.
In the automobile rear frame assembly that above-described embodiment describes, floor side member 21 can be provided with fluting 211.Fluting 211 absorbs energy for floor side member 21 in fluting 211 place crumple distortion, improves the energy-absorbing effect of floor side member 21.
In the automobile rear frame assembly that above-described embodiment describes, fluting 211 can be multiple.Multiple fluting 211 makes floor side member 21 fully absorb collision energy.
In the automobile rear frame assembly that above-described embodiment describes, the upper end perpendicular to bearing of trend that fluting 211 is positioned at floor side member 21, and along perpendicular to ground upward direction being V-structure; The weakening region of the corresponding spare wheel cover 22 in position of fluting 211.Fluting 211 is along perpendicular to ground upward direction being V-structure, then slot 211 perpendicular to the direction on ground being up big and down small structure, make floor side member 21 when fluting 211 crumple distortion absorbs collision energy, floor side member 21 is with the comparatively small end of V-structure for the center of circle upwards flip-flop movement, and the larger end of V-structure is bonded to each other with flip-flop movement simultaneously.Floor side member 21 upwards flip-flop movement can drive the spare wheel cover 22 be connected with it, the reinforcing device 24 be installed on spare wheel cover 22, fuel tank 23 upwards flip-flop movement together; make fuel tank 23 away from the structure of spare wheel cover 22 lower surface; protect fuel tank further, thus further increase vehicle safety.
The automobile rear frame assembly that above-described embodiment describes, can also comprise an after cross member 25, described after cross member 25 is fixedly connected between two floor side members 21, and is positioned at the side of weakening region 222 away from reinforcing device 24.After cross member 25, two floor side members 21 and back buffer beam 11 form a closing structure, the power stable delivery that collision is produced.
Above-described embodiment describe automobile rear frame assembly in, as shown in Figure 2, reinforcing device 24 can for two panting beams be parallel to each other, and two panting beams are parallel with floor side member 21, and between there is certain distance; Two panting beams can be equal with the distance between contiguous floor side member 21 respectively.Panting beam structure is convenient to the fixed pedestal of fuel tank 23.
By Fig. 2, the work process of the automobile rear frame assembly that above-described embodiment describes is described in detail below.
When after touch generation time, after back buffer beam 11 is out of shape absorption portion energy, energy transferring gives two floor side members 21, floor side member 21 is provided with fluting 211, floor side member 21 is made fully to absorb energy, meanwhile, back buffer beam 11 deformable squeeze rear end panel 16, makes collision energy pass to spare wheel cover 22 by rear end panel 16.Reinforcing device 24 is fixed on spare wheel cover 22, spare wheel cover 22 is made to there is reinforcement district 221 and weakening region 222, because reinforcement district 221 corresponds to region shared by reinforcing device 24 and reinforcing device 24 elongated area towards floor side member 21, make the intensity in reinforcement district 221 larger, relative weakening region 222 intensity is little, and fuel tank 23 position corresponds to reinforcement district 221, after touch generation time, reinforcement district 221 intensity large deformation is small, thus avoid reinforcement district 221 and be out of shape damage to fuel tank, and weakening region 222 intensity is little, distortion absorbs collision energy.
Wherein, when floor side member 21 absorbs energy in fluting 211 place crumple distortion, due to slot 211 along perpendicular in the upward direction of ground for V-structure, then slot 211 perpendicular to the direction on ground being up big and down small structure, make floor side member 21 when fluting 211 crumple distortion absorbs collision energy, floor side member 21 is with the comparatively small end of V-structure for the center of circle upwards flip-flop movement, and the larger end of V-structure is bonded to each other with flip-flop movement simultaneously.Floor side member 21 upwards flip-flop movement can drive the spare wheel cover 22 be connected with it, the reinforcing device 24 be installed on spare wheel cover 22, fuel tank 23 upwards flip-flop movement together, makes fuel tank 23 away from the structure of spare wheel cover 22 lower surface, thus effectively protects fuel tank.
The embodiment of the present invention also provides a kind of automobile, employs the automobile rear frame assembly that above-described embodiment describes.
