And existing Federal bumper, the main bumper/spoiler housing that leans on absorbs collision energy, and damping energy absorption performance is poor, well can not protect the life security of occupant.
Summary of the invention
In view of this, the object of this invention is to provide one and stretch out Multistage damping formula automobile bumper device in advance, to solve the function that existing Federal bumper does not have anticipation danger, crashproof preparation can not be carried out in advance and the problem such as damping energy absorption performance is poor.
The present invention stretches out Multistage damping formula automobile bumper device in advance, comprise bumper/spoiler housing, also comprise the damping oil cylinder be arranged on cross member of frame, the speed sensor of inspection vehicle wheel speed and the controller of control damping oil cylinder, described speed sensor and controller electrical connection, the piston rod end of described damping oil cylinder is provided with flexible block, and the middle part of described bumper/spoiler housing is provided with the window coordinated with flexible block;
Also comprise and be fixed on bumper/spoiler case inside and the some waveform energy-absorbing plates be arranged in juxtaposition along bumper/spoiler shell length direction.
Further, described stretch out in advance Multistage damping formula automobile bumper device also comprise be fixed on cross member of frame and with the orienting sleeve of damping oil cylinder piston rod bearing fit.
Further, described bumper/spoiler housing is connected with cross member of frame by energy-absorption box.
Further, described energy-absorption box comprises bellow-shaped shell.
Further, described energy-absorption box also comprises the damping spring be arranged in bellow-shaped shell.
Further, described energy-absorption box comprises regular hexagon shell and is arranged on the X-shaped cross board in regular hexagon shell.
Further, S shape energy-absorbing plate is provided with inside the two ends curved portions of described bumper/spoiler housing.
Beneficial effect of the present invention:
1, the present invention stretches out Multistage damping formula automobile bumper device in advance; its Negotiation speed sensor detects automobile driving speed; when automobile driving speed is in overspeed condition; the piston rod that controller just controls damping oil cylinder is in the state of stretching out; thus crashproof preparation can be carried out in advance; when colliding generation; damping oil cylinder can consume part impinges energy in advance; then in further knockout process, vehicle bumper shell consumes remaining Impact energy more further; thus better can protect the life security of occupant, impact protector performance is better.
2, the present invention stretches out Multistage damping formula automobile bumper device in advance, it has the Multistage damping parts such as damping oil cylinder, bumper/spoiler housing, waveform energy-absorbing plate, energy-absorption box, damping spring, thus form Multistage damping system, collision energy can be consumed step by step in collision process, absorption that can be larger consumes collision energy, its energy-absorbing damping power consumption process is faster more steady, better can ensure the life security of occupant.
Accompanying drawing explanation
Fig. 1 is the first structural representation that the present invention stretches out Multistage damping formula automobile bumper device in advance;
Fig. 2 is the second structural representation that the present invention stretches out Multistage damping formula automobile bumper device in advance;
Fig. 3 is the horizontal cross-sectional schematic of S shape energy-absorbing plate.
detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment stretches out Multistage damping formula automobile bumper device in advance, comprise bumper/spoiler housing 1, also comprise the damping oil cylinder 3 be arranged on cross member of frame 2, the speed sensor 4 of inspection vehicle wheel speed and the controller 5 of control damping oil cylinder, described speed sensor 4 and controller 5 are electrically connected, the piston rod end of described damping oil cylinder 3 is provided with flexible block 6, and the middle part of described bumper/spoiler housing 1 is provided with and keeps off 6 pieces of windows coordinated with elasticity;
Also comprise the some waveform energy-absorbing plates 7 being fixed on and being arranged in juxtaposition inside bumper/spoiler housing 1 and along bumper/spoiler housing 1 length direction.
In normal state, the piston rod of damping oil cylinder 3 stretches out certain distance makes flexible block 6 flush with bumper/spoiler housing 1, can not affect the outward appearance of bumper/spoiler.When speed sensor 4 detects that automobile driving speed is in overspeed condition; the piston rod that controller 5 just controls damping oil cylinder 3 is in and entirely stretches out state; thus crashproof preparation can be carried out in advance; when colliding generation; damping oil cylinder 3 can consume part impinges energy in advance; then in further knockout process, vehicle bumper shell consumes remaining Impact energy more further, thus better can protect the life security of occupant, and impact protector performance is better.
And the present embodiment Multistage damping formula automobile bumper device, it has the Multistage damping parts such as damping oil cylinder 3, bumper/spoiler housing 1, waveform energy-absorbing plate 7, thus in collision process, collision energy can be absorbed consumption step by step, it is strong that it absorbs energy-dissipating property, damping energy-absorbing can make collision process more relax step by step, better can ensure the life security of occupant.
As the improvement to the present embodiment, this stretch out in advance Multistage damping formula automobile bumper device also comprise be fixed on cross member of frame 2 and with the orienting sleeve 8 of damping oil cylinder 3 piston rod bearing fit; Orienting sleeve 8 can avoid the problems such as the piston rod of damping oil cylinder 3 deflects, the piston distortion of damping oil cylinder 3 in collision process, better can ensure that damping oil cylinder 3 normally works.
