Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle member structure, and more particularly to a vehicle member structure applied to a center member.

[0002]

2. Description of the Related Art As a conventional vehicle member structure, for example, one disclosed in Japanese Patent Laid-Open No. 55-160616 is known. In this structure, a pipe member is welded to the upper wall surface of the member, and a bracket or the like supporting the power unit is connected to the member by a bolt penetrating the pipe member. When such a structure is applied to, for example, a center member supporting a power unit, it is shown as shown in FIGS.

6 to 8, reference numeral 1 denotes a center member extending in the front-rear direction of the vehicle, and the center member 1 supports a power unit 4 via front and rear engine mounts 2 and 3. A bolt 4 connecting the engine mounts 2 and 3 to the center member 1 penetrates a pipe 5, and the pipe 5 is engaged with the center member 1 in a recess in the upper wall of the center member 1 as shown in FIG. It is fixed to the member 1 by welding. This recess is formed by drawing with a press.
FIG. 8 shows a welded state, and 6 is a weld bead. Further, a rain hose 7 for reinforcement is welded to the lower surface side of the upper wall of the center member 1.

[0004]

However, in the conventional member structure for a vehicle, the weight and cost are increased and the work such as welding is troublesome due to the following reasons. was there. That is, since the center member 1 needs to be drawn, the cost increases. Further, since the pipe 5 is placed on the curved concave portion and welded, it is difficult to position the pipe 5 with respect to the center member 1, workability is poor, and as shown in FIG. It is difficult to melt and it takes a lot of time for welding work. Furthermore, since the input to the center member 1 through the pipe 5 is received by the upper wall surface of the center member 1 which is orthogonal to this input, it is necessary to provide a rain hose 7 as a reinforcing member, which increases the weight and the cost. To do.

Therefore, an object of the present invention is to reduce the weight and cost as well as to reduce the time and effort required for processing work such as welding.

[0006]

In order to solve the above problems, the present invention provides a vehicle member structure for supporting a power unit, wherein a pair of side walls facing each other and an upper wall connecting the upper end portions of these side walls are connected to each other. And a member main body having a notch hole formed by notching the upper wall and extending in a direction opposite to the pair of side walls, and a pair of side walls having one end bent in a pipe shape. It is composed of a single plate with a width that approximately matches the distance, is inserted into the notch hole of the member main body from the other end side, and is fixed to the member main body by welding while the one end is locked to the upper ends of the pair of side walls It is characterized in that it is provided with a color.

[0007]

According to the present invention, when a vertical force is applied to the collar, the input is applied to the member main body as a parallel input to the pair of side walls. Therefore, the strength of the vehicle member structure is improved with respect to the vertical input received by the collar.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 5 are views showing an embodiment of a vehicle member structure according to the present invention. First, the configuration will be described. 1 to 5, 10 is a power unit, and the power unit 10 is supported by a vehicle member structure 12 via an engine mount 11. The vehicle member structure 12 includes a member main body 13 and a plurality of collars 14 and the like. The member body 13
A pair of side walls 13a, 13b facing each other and these side walls
It has an upper wall 13c that connects the upper end portions of 13a and 13b to each other, and has a notch hole 13d. Notch hole 13d
Is formed by cutting out the upper wall 13c and extends in the direction in which the pair of side walls 13a and 13b face each other. The collar 14 has one end 14a bent into a pipe shape, and has a pair of side walls 13a,
It is composed of a single plate having a width substantially corresponding to the separation distance of 13b. Then, as shown in FIG. 3, the collar 14 is inserted into the cutout hole 13d of the member main body 13 from the other end 14b side, and the one end 14
A is welded and fixed to the member main body 13 in a state of being locked to the upper ends of the pair of side walls 13a and 13b. Specifically, the collar 14 is welded to the side walls 13a and 13b and the upper wall 13c from the inside of the U-shaped member body 12 having an opening at the bottom.
FIG. 4 shows a welded state of the collar 14 and the upper wall 13c, and 20 in the figure is a weld bead.

On the other hand, the pipe portion 14c formed at the one end portion 14a of the collar 14 has a bolt engaging with the engine mount 11.
The engine mount 11 is supported by the member main body 13 via the collar 14 so as to penetrate therethrough. A pair of side walls 13a,
The front and rear ends of the vehicle 13b are connected to each other by a front wall 13e and a rear side wall 13f. Side wall 13
Jack-up receiving members 16 are welded to the vicinity of the vehicle front side ends of a and 13b, the front side wall 13e and the vehicle front side collar 14. The jack-up receiving member 16 is formed by welding plate members orthogonal to each other, and the bottom surface portion A where the plate members cross each other serves as a jack-up point.
18 is a reinforcing plate, 19 is a reinforcing member, and the reinforcing plate 18 and the reinforcing member 19 are welded to the side walls 13a, 13b and the upper wall 13c from the inside of the member main body 13.

According to the above configuration, the following operational effects can be obtained. Firstly, the pipe portion 14c of the collar 14 is fixed to the member main body 13 by utilizing the notch 13d formed in the upper wall 13c without drawing the upper wall 13c of the member main body 13. The cost can be reduced as compared with the conventional one that uses processing.

Secondly, the collar 14 can be positioned in each of the three-dimensional directions with respect to the member main body 13 simply by inserting the collar 14 into the cutout hole 13d of the member main body 13, so that the positioning operation can be facilitated. Third, the collar 14 is the member body 13
Since the pipe portion 14c is welded to the upper wall 13c while being inserted into the notch hole 13d, the weld bead 20 can be easily melted into the inside, and the pipe portion 14c can be inserted into the upper wall 13c.
The work of welding to can be facilitated. The pipe part 14c is placed on the upper ends of the side walls 13a and 13b, and
Since it is welded to No. 13, the strength is not inferior to that of the conventional welded pipe material placed in the recess formed by drawing.

Fourth, the engine mount 11 to the collar 14
When a vertical force is input to the member main body 13, the input is applied to the member main body 13 on the side walls 13a and 13b as an input parallel to the wall surface. Therefore, a conventional reinforcing material such as a rain hose that reinforces the member main body 13 against the vertical input received by the collar 14 can be eliminated, and the weight and cost can be reduced.

Fifth, since the rear end of the jack-up receiving member 16 on the vehicle rear side is welded to the front collar 14 of the vehicle, the collar 14 should have a stopper function for front-rear input due to road surface interference or the like. You can Sixth, color
Since 14 is also welded to the inner wall surfaces of the side walls 13a and 13b,
The collar 14 can be provided with a function as a blade that opposes the twisting input to the member main body 13.

[0014]

According to the present invention, since the collar is inserted into the notch hole formed by notching the upper wall of the member main body and welded and fixed to the member main body, the strength of the collar against the vertical input. It is possible to facilitate the welding work while improving the efficiency, reduce the weight and cost, and reduce the time and effort of the working work such as welding.
