Car grille shutter installation structure

Abstract

A grille shutter mounting structure of an automobile can ensure layout performance in a structure including an actuator for driving the shutter to open and close. A grille shutter unit (3) provided with a plurality of shutters (30) extending in the vehicle width direction is mounted on a frame-shaped guard (2), and is provided with a central portion in the width direction of the guard upper portion (21) and a shield. The central bracket (24) extending in the vertical direction is connected to the central part in the width direction of the lower part of the cover (22), and the grille shutter unit (3) is installed on the back side of the cover (2), ), an actuator (31) for driving the shutter (30) to open and close is arranged at the position on the back side of the center support (24).

Description

technical field [0001] The present invention relates to a grille shutter attachment structure of an automobile equipped with a grille shutter unit provided with a plurality of louvers extending in the vehicle width direction on a frame-shaped guard. Background technique [0002] As exemplified in Patent Document 1, a grille shutter mounting structure of an automobile includes an actuator that drives the shutter to open and close to control the introduction of outside air to the radiator according to the driving state of the vehicle. [0003] The opening and closing drive mechanism (36) including an actuator in Patent Document 1 is provided in side wall portions (43, 43) on both sides of a unit frame portion (31) included in a grille shutter unit (30) One (right side) side wall portion (43) side (refer to Patent Document 1 Figure 9 , Figure 11 ). [0004] However, in the structure in which the opening and closing drive mechanism (36) is provided on the side wall portion (...

Problems solved by technology

[0004] However, in the structure in which the opening and closing drive mechanism (36) is provided on the side wall portion (43) of the grille shutter unit (30), since it is installed on the vehicle width direction outer side with respect to the side wall portion (43), The protruding mounting flange (46) (refer to the same figure of Patent Document 1), so the opening and closing drive mechanism (36) protruding outward in the vehicle width direction than the side wall portion (43) may interfere with the side wall portion (43). ) in the vicinity of sensors and air guide members and other auxiliary equipment interfere, and on the other hand, when the opening and closing drive mechanism (36) is arranged on the inner side of the vehicle width direction than the side wall portion (43), the opening and closing The closing drive mechanism (36) will block the opening of the shield part (20), which may cause the opening area to shrink

In this structure with the opening and closing drive mechanism (36), it is easy to be restricted by the layout, so there is still room for improvement.
