Abstract
The utility model relates to a rear bumper technical field, concretely relates to rear bumper skeleton, be equipped with the main beam of kink, establish at the main installing support of main beam both ends side, all establish at the footboard support and two blocks of curb plates of main beam upper surface including the both ends symmetry to and establish the little installing support of several at the main beam lower surface, the cavity siphonozooid body of main beam formula structure as an organic whole. The utility model has high strength, good buffering and energy absorbing functions, simple manufacturing process and low manufacturing cost, and meets the requirement of the automobile on the strength of the bumper; as the main beam of the bumper of the basic vehicle type, in the process of designing and modifying, only the tubular body is needed to be used as the center, and the bracket is welded to the periphery of the tubular body at any angle, so that the degree of freedom is high, the main beam has good adaptability to various modified vehicles, the universality is high, and the modifying design and manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of automobile rear bumper technical field, is specifically related to a kind of automobile rear bumper skeleton.
Background technology
Existing automobile rear humper is general to adopt flat tabular main beam to be applied in the automobile rear humper, in the car conversion design, need support fixing on integral replacing main beam and the main beam, like this, basically abandoned the unit design of existing rear bumper arm, again according to the exterior design rear bumper arm of automobile rear, the remodeling cost is high.Because people improve constantly the demand of car conour, the poor defective of the structure commonality of existing automobile rear humper is more and more obvious, is not suitable for the demand for development of auto trade.In addition, existing tabular main beam also exist structural strength not, buffering energy-absorbing function can not bring into play well, and manufacturing process is complicated, the defectives such as manufacturing cost height.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of simple in structure, highly versatile is provided, the remodeling cost is low, structural strength is high, have good buffering energy-absorbing function, manufacturing process is simple, the automobile rear bumper skeleton of the advantage of low cost of manufacture.
To achieve these goals, the automobile rear bumper skeleton of the utility model design, comprise that two ends are arranged with the main beam of kink, are located at the main mounting bracket of side, main beam two ends, all are located at pedal support and two blocks of side plates of main beam upper surface, and several little mounting brackets that are located at the main beam lower surface, its special feature is that described main beam is the hollow tubular body of integral type structure.
In technique scheme, described main beam integral casting forming.
In technique scheme, described main mounting bracket is connected with the little mounting bracket that is fixed on the main beam two ends by bolt.
Main beam of the present utility model adopts integral type tubular body structure, and with respect to the flat platy structure of equal quality in the prior art, integral body has very high intensity, and tool has good buffering energy-absorbing function, satisfy automobile to the requirement of bumper strength, and manufacturing process is simple, low cost of manufacture; The utility model is as the safety lever main beam of basic vehicle, in the process that design development becomes, only need centered by tubular body, arbitrarily angled welding support can reach the purpose of remodeling around the tubular body, degree of freedom is high, various remodeling cars are had good comformability, and commonality is high, has reduced Transform Type design and cost of manufacture.
Description of drawings
Fig. 1 is integral structure scheme drawing of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is that the B-B of Fig. 1 is to cutaway view;
Fig. 4 is the automobile rear humper structural representation after the moulding of employing the utility model;
Among the figure: 1, main beam (11, kink); 2, main mounting bracket; 3, pedal support; 4, little mounting bracket; 5, side plate; 6, housing; 7, bolt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Such as Fig. 1, Fig. 2 and automobile rear bumper skeleton shown in Figure 3, comprise that two ends are arranged with the main beam 1 of kink 11, are located at the main mounting bracket 2 of side, main beam 1 two ends, all are located at pedal support 3 and two blocks of side plates 5 of main beam 1 upper surface, and several little mounting brackets 4 that are located at main beam 1 lower surface, main beam 1 is the hollow tubular body of integral type structure.Main mounting bracket 2 is connected with the little mounting bracket 4 that is fixed on main beam 1 two ends by bolt 7, and main beam 1 inblock cast is one-body molded.
Make in the utility model process, as main beam 1, the little mounting bracket 4 with various difference in functionalitys is welded on the main beam 1 again with metal circular tube, and main mounting bracket 2 is connected with little mounting bracket 4 by bolt.During use, with rear bumper arm housing 6(on the automobile rear bumper skeleton outside mask shown in Figure 1 as shown in Figure 4), the safety lever position that is installed in the automobile back gets final product, in remodeling car design process, can need only corresponding support outwards be set centered by main beam 1 according to different bumper/spoiler shapes, the cost of Transform Type design after being convenient to control; Main beam 2 adopts the tubular body structure of integral type, and it is good to have overall construction intensity, has good buffering energy-absorbing function.
