Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a jack mounting structure for an automobile.

(Prior Art) In automobiles, jacks are generally stored and supported in the trunk, and in this case, the above-mentioned general mounting structure is, for example,
As disclosed in Japanese Patent No. 128959, there is a structure in which a bracket for mounting and supporting a jack is attached to a floor frame forming the bottom surface of a trunk room.

(Problem to be solved by the invention) However, in this known example, since the part to which the bracket is attached has a plate structure consisting only of the floor panel, the support rigidity against vertical loads is particularly poor. Therefore, there was a problem in that the jacks were susceptible to vibrations due to vibrations during driving.

Therefore, the present invention aims to increase the supporting rigidity of a jack in which the jack is fixed to the floor panel side via a bracket.

(Means for solving the problem) In order to solve such problems, this invention
In an automobile in which a jack is stored and supported via a bracket on a floor panel constituting the bottom surface of a trunk room, a hat-shaped frame member having flanges extending on both left and right sides is attached to the lower surface side of the floor panel. The flange is arranged in abutment with the floor panel to form a closed cross section with the floor panel, and the axial end of the frame member is joined to a panel member extending in a direction substantially perpendicular to the flange. On the other hand, the bracket includes left and right flanges corresponding to the flanges of the frame member, left and right legs that extend in a direction substantially perpendicular to these flanges, and a leg that extends across the legs and extends between the flanges. The floor panel is formed into a hat-shaped cross-sectional shape with a jack mounting portion composed of planes extending substantially parallel to each other, and each flange of the floor panel is arranged to face each flange of the frame member on the upper surface side of the floor panel. is fixed with a closed cross section formed between the
Between the bracket and the panel material, a jack is placed on the jack mounting portion of the bracket, and the jack is fastened to the panel material in the axial direction of the frame member. The present invention is characterized in that a fixing member is provided to restrict expansion displacement of the jack in the plane direction of the panel material.

(Function) With this configuration, the bracket having the jack mounting portion disposed on the upper surface side of the floor panel has a flange that is attached to the floor panel with respect to the flange of the frame member disposed on the lower surface side of the floor panel. The rigidity of the floor panel is extremely high due to the closed cross section formed by the bracket on the upper surface side of the floor panel and the closed cross section formed by the frame member on the lower surface side of the floor panel.

Then, the jack is placed on the jack mounting part of the bracket having such high rigidity,
This is fastened to the panel member by the fixing member in the axial direction of the frame member (i.e., approximately horizontal direction), and the jack is fastened to the panel member in the plane direction of the panel (i.e., in the vertical direction). The vertical displacement between the bracket and the bracket is restricted.

In this case, when the jack is attached to the bracket and the bracket is expanded slightly to generate a predetermined holding force between the bracket and the fixing member to hold it, the holding force is applied to the legs of the bracket. The energy is distributed to the floor panel and frame members through the support, and together with the high rigidity structure of the bracket, high support performance can be obtained.

(Effects of the invention) Therefore, according to the vehicle jack mounting structure of the present invention, the jack is supported by the bracket which ensures high support rigidity in combination with the frame member. This reliably prevents the jack from vibrating during driving, which is the case with the low-rigidity support structure in which the bracket is supported only by the rigidity of the floor plate as in the above-mentioned known example.
