Description

[Detailed description of the invention] Industrial application field Bumper with an opening for automobiles Conventional technology In a bumper with an opening as shown in FIG. Ribs 03 having a U-shape or V-shape are arranged horizontally.

Problems that the invention aims to solve: When a person stands in front of the bumper, the inside of the bumper, for example, the body cross member 04, passes through the gaps between the ribs 03.
etc. can be visually observed and spoil the aesthetic appearance.

Means for solving the problem: an opening formed in a plate-shaped bumper frame disposed on the outer surface of the vehicle body and communicating between the outside and the inside of the bumper frame; partitioned into a plurality of ventilation holes, and at least one rib extending along the longitudinal direction of the bumper frame, the rib extending along the vertical direction in a cross section perpendicular to the longitudinal direction. a lower surface extending from the lower end of the front surface toward the inner side of the bumper frame, an upper surface extending from the upper end of the front surface toward the inner side of the bumper frame, and an upper surface extending upward from the extending end of the upper surface. The extending length of the lower surface to the inside of the bumper frame is set shorter than the extending length of the upper surface to the inside of the bumper frame, and the extending end of the vertical portion is In the vicinity of the horizontal extension line of the lower extending end of the rib directly above or the upper edge of the opening directly above, and deviated toward the inner side of the bumper frame than the extending lower end of the rib directly above or the upper edge of the opening directly above. The extending end of the lower surface is near the extending end of the vertical part of the rib immediately below or the horizontal extension line of the lower edge of the opening immediately below, and It extends to a position offset to the outside of the bumper frame from the lower edge of the opening.

Function: Only the rib or bumper frame is visible; the inside of the bumper is not visible, and the amount of ventilation does not decrease.

Embodiment In FIGS. 1 and 2, 1 is a bumper frame, 2 is an opening of the bumper frame 1, 3 is a rib,
3a is the upper surface of the rib 3, 3b is the lower surface of the rib 3, 3c
is a vertical portion of the upper surface 3a, and 4 is a body cross member.

When the shape of the rib 3 or bumper frame 1 of the present invention is compared with that of the conventional device, it becomes as shown in FIG. 3, in which the dashed line portion is the removed rib portion and the hatched portion is added.

As shown in FIG. 1, the inside of the bumper cannot be visually seen through the gap between the ribs 3.

Effects of the invention According to the invention of the present application, the ribs arranged in the opening that communicates between the outside and the inside of the bumper frame and partitioning into a plurality of ventilation holes extend in the vertical direction in a cross section perpendicular to the longitudinal direction of the bumper frame. a lower surface that extends from the lower end of the front surface toward the inside of the bumper frame, an upper surface that extends from the upper end of the front surface toward the inside of the bumper frame, and a vertical portion that extends upward from the extending end of the upper surface. In addition, the extension length of the lower surface to the inside of the bumper frame is set shorter than the extension length of the upper surface to the inside of the bumper frame, and the extending end of the vertical part is the lower extending end of the rib directly above or Near the horizontal extension of the upper edge of the opening directly above, and extending to a position deviated inward from the bumper frame than the lower extending end of the rib directly above or the upper edge of the opening directly above, and the extending end of the lower surface is horizontally near the extending end of the vertical part of the rib directly below or the lower edge of the opening directly below, and extends to a position offset to the outside of the bumper frame from the extending end of the vertical part of the rib directly below or the lower edge of the opening directly below. As a result, a desired amount of opening is formed between the extending end of the vertical part and the extending end of the lower surface to ensure the necessary amount of ventilation into the engine compartment, while also making it possible to maintain the same shape as the bumper frame. Even if you look into the opening of the bumper frame from a position at approximately the same height, that is, from a relatively low position, the vertical part formed in the rib will reliably block the line of sight toward the engine room, making it possible to see inside the engine room. However, the appearance of the front part of the vehicle body can be improved. Further, in the configuration of the present application, since the rib is configured from a plurality of surfaces (front surface, upper surface, lower surface, and vertical portion), the strength of the entire rib is increased, and the mounting rigidity to the bumper frame is also increased.

Claims (1)

[Scope of utility model registration request] An opening formed in a plate-shaped bumper frame disposed on the outer surface of the vehicle body and communicating between the outside and the inside of the bumper frame, and an opening disposed in the opening to divide the opening into a plurality of ventilation holes. and at least one rib extending along the longitudinal direction of the bumper frame, and the rib includes a front surface extending in the vertical direction in a cross section perpendicular to the longitudinal direction, and a front surface extending from the lower end of the front surface to the above-mentioned It is comprised of a lower surface extending toward the inside of the bumper frame, an upper surface extending toward the inside of the bumper frame from the upper end of the front surface, and a vertical portion extending upward from the extending end of the upper surface. The extension length of the lower surface to the inside of the bumper frame is set shorter than the extension length of the upper surface to the inside of the bumper frame, and the extending end of the vertical portion is the lower extending end of the rib directly above. or in the vicinity of the horizontal extension line of the upper edge of the opening directly above, and extending to a position deviated inward from the bumper frame than the lower surface extension end of the rib directly above or the upper edge of the opening directly above, and The extending end is near the extending end of the vertical part of the rib immediately below or the horizontal extension line of the lower edge of the opening immediately below, and is further outside the bumper frame than the extending end of the vertical part of the rib immediately below or the lower edge of the opening immediately below. The rib structure of the bumper opening is characterized by extending to a position deviated from the center.
