Description

Internal-division structural bumper

Technical Field

The utility model belongs to the technical field of bumpers, and particularly relates to an internal parting structure bumper.

Background

The front and rear ends of the automobile are provided with bumpers (bumpers), which not only have the decoration function, but also are safety devices for absorbing and buffering external impact force, protecting the automobile body and protecting the safety function of passengers.

For an automobile bumper plastic part, two parting modes of external parting and internal parting are generally adopted. For large-area back-off on two sides of all automobile bumpers, external parting can be adopted or internal parting can be adopted. The selection of the two parting modes mainly depends on the requirements of a final client automobile host factory on bumpers, and common European and American automobiles mostly adopt an inner parting technology, and daily automobiles mostly adopt outer parting. The two parting modes have the advantages that the outer parting type bumper needs to be processed for clamping wires, and the processing procedure is increased, but the cost and the technical difficulty of the outer parting type bumper are lower than those of the inner parting type bumper, and the inner parting type bumper is difficult to demold due to large-area back-off.

Detailed Description

Embodiments of the split mechanism bumper of the present utility model are further described with reference to fig. 1-5.

In the description of the present utility model, it should be noted that, for the azimuth words such as the terms "center", "transverse (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, only for convenience of describing the present utility model and simplifying the description, but do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and should not be construed as limiting the specific protection scope of the present utility model.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features. Thus, the definition of "a first", "a second" feature may explicitly or implicitly include one or more of such feature, and in the description of the present utility model, the meaning of "a number", "a number" is two or more, unless otherwise specifically defined.

The utility model provides an interior type structure bumper, includes windward portion 1 and wind-guiding portion 2, wind-guiding portion 2 is provided with two, and two wind-guiding portions 2 are located windward portion 1's both sides respectively, windward portion 1 all is provided with hem 11 with the edge of wind-guiding portion 2, windward portion 1 is connected through the fastener with the hem 11 department that wind-guiding portion 2 is close to mutually.

In this embodiment, the bumper is integrally made of plastic, and the three parts, namely, the windward part 1 and the two air guiding parts 2, are all formed by injection molding, and the three parts can be independently injection molded and connected by fasteners at a later stage, and specifically, through holes can be formed in the folded edges 11, and then the folded edges can be fixed by rivets or screws penetrating through the through holes.

In this embodiment, the windward portion 1 is a substantially flat surface, and the wind guiding portion 2 is an inclined surface, as shown in fig. 1, the wind guiding portion 2 is bent and inclined backward from the edge of the windward portion 1, and after the actual loading, the air resistance of the windward portion 1 is far greater than that of the wind guiding portion 2.

As shown in fig. 2, in this embodiment, the flanges 11 of the windward portion 1 and the air guiding portion 2 are folded back, and of course, the flanges 11 are integrally injection molded with the main body thereof.

As shown in fig. 2, the back of the windward portion 1 is preferably provided with a plurality of ribs 12.

By arranging the ribs 12, the strength of the windward part 1 can be enhanced, firstly, the overall shape of the windward part 1 can be ensured to be stable in the demolding process, and the size of the single wind guiding part 2 is far smaller than that of the windward part 1, so that the single wind guiding part is easy to demold and mold, secondly, the windward part 1 receives stronger wind pressure in the driving process, the strength of the windward part can be ensured by arranging the ribs 12, the pressure can be dispersed to all positions of the windward part 1, and the single wind guiding part 2 is obliquely arranged, has small wind pressure and is not easy to deform, so that the ribs 12 are not required to be arranged.
