Abstract
The utility model discloses a car bumper energy-absorbing device which comprises an energy-absorbing box (1), wherein one end of the energy-absorbing box (1) is melted and welded on a bumper crossbeam (2), and the other end thereof is melted and welded on a bumper mounting outer board (3), the bumper mounting outer board (3) is connected with a bumper mounting inner board (5) through a bolt (4), a longitudinal beam (7) is melted and welded on bumper mounting inner board (5), the energy-absorbing box (1) is hollow, and filler (6) is filled in the hollow cavity thereof, is foam-like or honeycomb-like or multi-cell like, and is fixed in the energy-absorbing box (1) through adhesive. The car bumper energy-absorbing device with the structure increases the energy absorption effect of the energy-absorbing box through mounting filler in the middle of a common front bumper energy-absorbing box, the filler makes the crushing of the energy-absorbing box more stable, and can be increased or decreased according to requirements for changing the crushing pressure, thereby enabling the energy-absorbing box to reach ideal energy-absorbing effect.
Description
Technical field
The utility model relates to a kind of energy absorption device, especially relates to a kind of car bumper energy absorption device.
Background technology
Important energy absorption device when car bumper energy-absorbing box is collision happens.Desirable energy-absorbing box need possess following characteristics: self fully be out of shape in the low speed collision to absorb most of collision energy, the expensive parts of protection motorcar body agent structure and chassis and electric system are not received damage; In the high-speed crash, the energy-absorbing box fully is out of shape, and absorbs more multipotency as far as possible, and the residual body in distortion back can transmit late collision load reposefully simultaneously.
Existing energy-absorbing box generally is welded into hollow structure by two metal panel beatings, distributes on two panel beatings to induce distressed structure, as: perforate, induce groove etc.; Yet in actual use, the stressed back conquassation of this kind energy-absorbing box power is inhomogeneous, and the less stable of distortion is not very good thereby cause energy-absorbing effect.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of car bumper energy absorption device at problems of the prior art, its objective is and make the energy-absorbing box when collision, produce uniform conquassation power, can transmit impact load by pulsation-free, improve the energy-absorbing effect of energy-absorbing box.
The technical solution of the utility model is that this a kind of car bumper energy absorption device comprises the energy-absorbing box, one end melting of energy-absorbing box is on bumper beam, other end melting is on the bumper mounting outside plate, bumper mounting outside plate and bumper mounting inner panel are by bolted connection together, the longeron melting is on the bumper mounting inner panel, the energy-absorbing box is a hollow structure, in its cavity weighting material is installed.
Described weighting material is spumescence or cellular or many born of the same parents shape.
Described weighting material is fixed on the adapter plate of energy-absorbing box by adhesive agent, and fills the whole cavity of full whole energy-absorbing box.
Or described weighting material by adhesive agent be fixed on the energy-absorbing box around.
A kind of car bumper energy absorption device with said structure has the following advantages:
1, this kind car bumper energy absorption device is installed weighting material in the middle of common front bumper energy-absorbing box, increase the energy-absorbing effect of energy-absorbing box, weighting material makes the conquassation of energy-absorbing box more stable, and can add and subtract the structure material of being filled as required, change conquassation power, make the energy-absorbing box reach desirable energy-absorbing effect.
2, this kind car bumper energy absorption device simple in structure, be easy to realize to have good application and popularization value.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 overlooks the partial schematic sectional view of direction for structure shown in Figure 1.
In Fig. 1～Fig. 2,1: the energy-absorbing box; 2: bumper beam; 3: the bumper mounting outside plate; 4: bolt; 5: the bumper mounting inner panel; 6: weighting material; 7: longeron.
The specific embodiment
Figure 1 shows that the structural representation of a kind of car bumper energy absorption device of the utility model, Fig. 2 overlooks the partial schematic sectional view of direction for structure shown in Figure 1, by Fig. 1 and Fig. 2 in conjunction with as can be known, this kind car bumper energy absorption device comprises energy-absorbing box 1, one end melting of energy-absorbing box 1 is on bumper beam 2, other end melting is on bumper mounting outside plate 3, bumper mounting outside plate 3 links together by bolt 4 with bumper mounting inner panel 5, longeron 7 meltings are on bumper mounting inner panel 5, energy-absorbing box 1 is a hollow structure, weighting material 6 is installed in its cavity, weighting material 6 can be foamed materials or cellular material or many born of the same parents material, and be fixed on by adhesive agent on the adapter plate of energy-absorbing box 1, and fill the whole cavity of full whole energy-absorbing box 1.
Also can be, weighting material 6 by adhesive agent be fixed on energy-absorbing box 1 around.
When vehicle collision, weighting material 6 in the front bumper energy-absorbing box 1 will improve the deformation stability of energy-absorbing box 1, simultaneously, because the conquassation effect of weighting material 6 is very desirable, and conquassation power can pass through to regulate the density change of weighting material 6, thereby realizes best energy-absorbing effect.
Claims (4)
