Regarding mounting structure.

[0002]

[Prior Art]

 For example, some automatic vehicles have a structure in which a shift lever for switching operation of each range is arranged on the floor panel. Conventionally, the structure shown in FIGS. 4 and 5 is used as the structure for mounting such a shift lever. is there. In this, the shift lever plate 21 is fixed to the upper surface of the floor tunnel 20a of the floor panel 20 by bolts 22, and the shift lever assembly 23 is attached to the plate 21. Further, the floor tunnel 20a and the plate 21 are formed with holes 26 into which the fulcrums 24a of the shift lever 24 are inserted. Further, the front edge portion 21a of the shift lever plate 21 is bent in an upright shape, and the front edge portion 21a supports the control cable 27. By the way, on the upper surface of the floor panel 20, a soundproof and vibration damping sheet member 25 is laid by welding in order to absorb noise from the engine and vibration during traveling. When the seat member 25 is laid, an opening 25a is cut out at a portion where the shift lever plate 21 abuts, and the plate 21 can be directly mounted on the floor tunnel 20a in the opening 25a.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional mounting structure, the front edge portion 21a of the shift lever plate 21 that supports the control cable 27 needs to be positioned in front of the vehicle body in order to secure the stroke amount of the shift lever 24. There is a problem that the size of 21 becomes large and the opening 25a of the sheet member 25 becomes large accordingly, resulting in low effect of suppressing noise and vibration.

Here, in order to make the opening of the seat member as small as possible, for example, Japanese Utility Model Laid-Open No. 1-73084 discloses a convex portion for mounting a shift lever plate at an interval on the upper surface of a floor tunnel. A structure has been proposed in which projecting structures are provided and a damping material is laid between the projecting parts. However, with this structure, the mounting rigidity of the shift lever plate is low, and since the gap between the above-mentioned convex parts is narrow, it is difficult for the damping material to stick to it, and problems such as tearing or swelling on the convex parts tend to occur. ..

The present invention has been made in view of the above-mentioned conventional circumstances, and the opening of the sheet member can be made small without causing the problems of lowering the mounting rigidity and making it difficult for the sheet member to be attached, and as a result, noise. Another object of the present invention is to provide a shift lever plate mounting structure for an automobile, which can improve the effect of suppressing vibration.

[0006]

[Means for Solving the Problems]

 Therefore, the present invention proposes a vehicle shift system in which a soundproof and vibration damping seat member is laid on the upper surface of the floor panel, and the shift lever plate is bolted and fixed to the exposed portion of the above-mentioned floor panel cutout. In the lever plate mounting structure, a step portion is formed by bending the edge portion of the shift lever plate, and an extension portion formed by extending the cutting edge portion of the sheet member is inserted between the step portion and the floor panel. It is characterized by being placed.

[0007]

[Action]

 According to the structure for mounting the shift lever plate according to the present invention, the step portion is formed by bending the edge portion of the shift lever plate, and the extension portion of the seat member is inserted and arranged between the step portion and the floor panel. The cutting area of the sheet member can be reduced by this extension, and the effect of suppressing noise and vibration can be improved accordingly. Further, since the shift lever plate is directly bolted to the floor panel and the edge portion is bent, the rigidity of the shift lever plate itself is improved, and the rigidity is not lowered as in the above publication. Furthermore, since the sheet member has a structure in which it is extended as it is, the problem of difficulty in sticking does not occur.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are views for explaining a shift lever plate mounting structure of an automobile according to a first embodiment of the present invention. In this embodiment, a case where a shift lever of an automatic vehicle is mounted will be described as an example. In the figure, 1 is a floor panel of an automobile, and a convex floor tunnel 1a extending in the vehicle front-rear direction is formed in the center of the panel 1. A substantially elliptical shift lever mounting hole 2 is formed in the floor tunnel 1a, and a plurality of bolt holes 3 are formed in the periphery of the hole 2.

A soundproof and vibration damping sheet member 6 is laid on the upper surface of the floor panel 1. The sheet member 6 is welded to the floor panel 1 in a hot air oven. A rectangular opening 6a is formed in the shift lever mounting hole 2 portion of the seat member 6, and the peripheral edge of the hole 2 of the floor panel 1 is exposed by the opening 6a. In addition, 6b is an opening for securing the console box mounting space 4 and the inner pillar member mounting space 5.

The shift lever plate 7 of the present embodiment is arranged in the opening 6a of the seat member 6 of the floor tunnel 1a, and is fixed by tightening the bolt 8 inserted into the bolt hole 3. .. This plate 7 has a substantially rectangular plate shape, and a flange portion 7a is bent and formed at the front edge of the plate 7, and a hole 7b having the same shape as the shift lever mounting hole 2 is formed in the central portion. Has been formed.

A shift lever assembly 10 is mounted on the shift lever plate 7. In this shift lever assembly 10, a cup-shaped shift lever boot 11 is inserted and arranged in the holes 2 and 7b, and a range box 12 is arranged on the upper part of the shift lever boot 11, and the box 12 and the boot 11 are not shown. The flange is fixed together with the shift lever plate 7 to the floor tunnel 1a, and a shift lever 13 is arranged in the range box 12. The lower end portion 13a of the shift lever 13 is located inside the shift lever boot 11 and is rotatably supported by the boot 11. Further, the knob 13b connected to the upper end of the shift lever 13 projects from the range box 12.

Further, one end of an inner cable 16 of the control cable 15 is connected to a central portion of the shift lever 13, and an extension end of the cable 16 is connected to an automatic transmission of an engine. Further, the supporting portion 17a of the outer cable 17 of the control cable 15 is fixed to the flange portion 7a of the shift lever plate 7, whereby the range is switched by swinging the shift lever 13 in the front-back direction. Is configured.

A step portion 18 is bent and formed in a step shape at a front edge portion of the shift lever plate 7, and an opening of the sheet member 6 is provided in a gap between the step portion 18 and the floor tunnel 1a. An extension portion 6a 'formed by extending the front edge portion of 6a rearward is inserted and arranged, and is welded onto the floor tunnel 1a.

Next, the function and effect of this embodiment will be described. According to the mounting structure of this embodiment, since the step portion 18 is formed by bending the shift lever plate 7, the seat member 6 can be extended between the step portion 18 and the floor panel 1. As shown in FIG. 2, the conventional opening front (dashed line) position can be extended to the rear of the vehicle body, and the opening 6a of the seat member 6 can be made smaller accordingly. As a result, the effect of blocking the transmitted sound of the engine and the muffled sound at high speed can be improved, and the effect of suppressing vibration during traveling can be improved. Since it is possible to form the elongated portion 6a 'in the seat member 6, it is necessary to increase the distance between the console box mounting opening 6b of the seat member 6 and the opening 6a of the shift lever plate 7. Therefore, problems such as tearing when welding the sheet member 6 can be solved. This solves the problem that the sheet member is difficult to attach due to the short distance between the openings in the conventional structure.

Further, in this embodiment, since the shift lever plate 7 is directly bolted to the floor tunnel 1a, the rigidity is not lowered as in the above-mentioned conventional publication, and the plate 7 is not stepped. Since the portion 18 is formed by bending, the rigidity of the plate 7 itself is improved, and the supporting rigidity of the control cable 15 can be improved.

In the above embodiment, the step portion 18 is formed only on the front edge portion of the shift lever plate 7, but the present invention is not limited to this, and there are left and right side edge portions, for example. Alternatively, the rear edge portion may also be formed in a step shape. In the above embodiment, an automatic vehicle is taken as an example, but the present invention can be applied to a manual vehicle.

In the above embodiment, the shift lever plate is arranged in the opening of the seat member. However, in the present invention, the shift lever plate 7 is arranged behind the seat member 6 as shown in FIG. Applicable. In this case, the rear extension portion 6c of the seat member 6 is inserted and arranged between the step portion 18 of the shift lever plate 7 and the floor panel 1.
