Abstract

PURPOSE:To obtain a light-weight structure and improve noise insulating efficiency of a hollow pillar communicating the outside of a vehicle and an air cleaner by disposing a seat belt take-up device receiving case and an insulating plate in such a manner as to close the pillar above a draft hole and an air cleaner communication hole. CONSTITUTION:The pillar inner 12 is formed with an insertion hole 15 for a case 30 in which a seat belt take-up device 50 is received above a draft hole 14 of the pillar outer 11 and an air cleaner communication hole 16 of the pillar inner 12. An insulating plate 20 having a cutout 22 for receiving the case 30 is fixedly secured to the inner wall of the pillar outer 11 facing to the insertion hole 15, so that the case 30 inserted through the insertion hole 15 can be connected to the cutout 22. This structure causes the pillar hollow portion 13 to be closed by the case 30 and the insulating plate 20, making the insulating plate smaller and more light-weight by the amount corresponding to the cutout. Further, complete noise insulation is achieved, improving insulating efficiency of the suction air noise.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pillar structure for an automobile in which a hollow portion of the pillar communicates with the outside of the vehicle and the air cleaner side.

(Prior art) As a conventional pillar structure of an automobile, for example,
A structure as described in Japanese Patent No. 9-4816 is known.

In this conventional structure, a shielding plate with small holes bored therein was provided in the hollow portion of the pillar above the ventilation port of the pillar outer and the communication port of the pillar inner.

The small holes have functions such as draining air and paint during panel painting (electrodeposition coating), draining water to prevent rust from the panel, and ventilating the inner space from moisture.

(Problems to be Solved by the Invention) However, in such a conventional automobile pillar structure, the shielding plate is formed to have the same size as the cross-sectional area of the pillar hollow part, and the small hole is not formed. Because the hole was opened, there were problems listed below.

(b) The size of the shielding plate is large and the weight increases significantly.

(b) Air cleaner intake noise leaks through the small hole, and the sound shielding is not sufficient.

(c) When using the pillar space to drain drain water from an air conditioner or sliding roof installed on the roof side, if you stop the drain hose above the shielding plate, the water will fall onto the shielding plate. Rust occurs.

In addition, if the drain hose is to extend below the shield plate, a hole must be made in the shield plate and the drain hose must be passed through the hole, but the shield plate is provided on the closed section of the pillar. Therefore, the task is extremely difficult.

(Means for Solving the Problems) Therefore, in order to solve the above-mentioned conventional problems, in the present invention, a hollow pillar is formed in the vehicle body by a pillar outer and a pillar inner, and the hollow part of the pillar is A ventilation port opened in the pillar inner and an air cleaner communication port opened in the pillar inner communicate with the outside of the vehicle and the air cleaner side, and an insertion port is opened in the pillar inner above the ventilation port and the air cleaner communication port, and the insertion port A shielding plate having a notch for a storage case formed on the insertion opening side is installed in a substantially horizontal state inscribed in the pillar to the open cross section of the pillar, and is installed in a substantially horizontal state to accommodate a storage case for the seatbelt retractor. The case is inserted into the pillar from the insertion port and comes into contact with the notch to shield the hollow part of the pillar,
The means is attached to the pillar inner.

(Function) Therefore, in the automobile pillar structure of the present invention, the air intake noise of the air cleaner is insulated by blocking the hollow portion of the pillar with a shielding plate and a storage case.

Further, even after the pillar outer and the pillar inner are joined together, work around the shielding plate can be performed through the insertion opening of the pillar inner.

In addition, by installing the storage case (completely closing the hollow part) after the painting process, the removal of air and paint during painting can be ensured through cutouts, etc. No need to make holes.
