Abstract
The utility model discloses an EPP buffering energy absorption block for a front bumper of an automobile. The EPP buffering energy absorption block comprises an energy absorption block body, wherein the whole energy absorption block body is arc-shaped and is an integral EPP cast part; positioning slots are symmetrically formed in two ends of the outer surface of the energy absorption block body; and three positioning holes fixed with the inner side of a main body of a cross beam of the bumper are formed in the middle position of the outer surface of the energy absorption block body. The EPP buffering energy absorption block is mounted on an automobile body through the positioning slots symmetrically formed in two ends of the outer surface of the energy absorption block body, and the positioning holes are fixed in the inner side of the main body of the cross beam of the bumper through screws, so that the mounting speed is increased, the structural strength is enhanced, and the stability of the energy absorption block is strengthened.
Description
Technical field
The utility model relates to a kind of EPP buffering energy-absorbing piece, is specifically related to a kind of EPP buffering energy-absorbing piece for automobile front beam.
Background technology
Bumper/spoiler is the important component part of modern automobile structure as safety device, and it can alleviate personal casualty degree and automobile damage rate effectively.Press the function of bumper/spoiler, can be divided into non-energy-absorption type and energy-absorption type.Because bumper assembly is in " low speed collision " and " pedestrian protecting " this decisive role aspect two, so it is the primary study content in domestic and international vehicle passive safety field.
Energy absorbing bumper can roughly be divided three classes by the mode difference of buffering energy-absorbing: self energy-absorption type, hydraulic pressure energy-absorption type, band air cavity type.Wherein, self this type of energy-absorbing type bumper is fairly simple, is made up of whippletree, the inboard reinforcement of whippletree and buffering energy absorbent block etc.The buffering energy-absorbing piece places between whippletree U-shaped face and the reinforcement, deforms to absorb energy when collision.Therefore, buffering energy-absorbing piece reasonable in design is most important for the performance of bumper/spoiler function of safety protection.
The utility model content
Technical problem to be solved in the utility model provides a kind of intensity height and processes the EPP buffering energy-absorbing piece that is used for automobile front beam simple, easy for installation.
For solving the problems of the technologies described above, a kind of EPP buffering energy-absorbing piece for automobile front beam of the utility model, comprise the energy absorbent block body, described energy absorbent block body integral body is arcuation, described energy absorbent block body is the unit-cast unit spare of expanded polypropylene EPP, the two ends of described this external surface of energy absorbent block are arranged with positioning groove, and the midway location place of this external surface of energy absorbent block is provided with three knock holees of fixing with bumper beam main body inboard.
For further improving the utility model steadiness and structural strength in use, the positioning groove that is symmetricly set on described this external surface of energy absorbent block two ends has four.
Above-mentioned positioning groove is oval.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is reasonable in design, and is easy for installation, is installed on the car body by the symmetrically arranged positioning groove in two ends, knock hole is fixed on bumper beam main body inboard by screw, not only improve installation rate, and increased structural strength, strengthened the stability of energy absorbent block.The utility model is the unit-cast unit spare of EPP, low processing cost, and energy-absorbing effect is good, can alleviate the car body damage.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of EPP buffering energy-absorbing piece for automobile front beam of the utility model;
Fig. 2 is the assembling scheme drawing of the utility model and bumper/spoiler.
The specific embodiment
As shown in Figure 1, a kind of EPP buffering energy-absorbing piece for automobile front beam, comprise energy absorbent block body 1, described energy absorbent block body 1 integral body is arcuation, described energy absorbent block body 1 is the unit-cast unit spare of expanded polypropylene EPP, the two ends of described energy absorbent block body 1 outside face are arranged with positioning groove 3, and the midway location place of energy absorbent block body 1 outside face is provided with three knock holees 2 that fix with bumper beam main body 4 inboards.The positioning groove 3 that is symmetricly set on described energy absorbent block body 1 outside face two ends has four.Described positioning groove 3 is oval.
The utility model when mounted, be installed on the car body 5 by the symmetrically arranged positioning groove 3 in its two ends, knock hole 2 is fixed on the inboard of bumper beam main body 4 by screw, has not only improved installation rate, and increased structural strength, strengthened the stability of energy absorbent block.Simultaneously, the utility model is the unit-cast unit spare of EPP, low processing cost, and energy-absorbing effect is good.
