Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure of an underguard which is mounted so as to cover a front lower part of a vehicle body such as a front skirt and a radiator panel and a lower part of an engine oil pan and the like in an automobile.

[0002]

[Prior art]

 The underguard of a vehicle guards the front vehicle body (front skirt, radiator panel, etc.) and the oil pan of the engine, etc., as described above, and is conventionally under the front vehicle body (eg, front end cross member). Fix the left and right mounting brackets to the lower parts of the side frames, join the front parts of the underguards to the left and right mounting brackets from below and fix them with bolts, etc. Is generally fixed to the side frame by bolting or the like (see, for example, Japanese Utility Model Laid-Open No. 58-79478 and Japanese Utility Model Laid-Open No. 1-67183). The underguard is often handled as an optional part.

[0003]

[Problems to be solved by the device]

 The purpose of the underguard is to protect the front body, oil pan, etc. as described above, but in recent years, the front end of the underguard is directed upward from the lower part of the front body to the front of the front body due to fashionability. It has come to be used to improve the appeal when viewed from the front, but when using a large underguard like this, it is necessary to make the mounting structure large and strong. There is.

In such a case, in the above-mentioned conventional underguard mounting structure, a large and strong mounting bracket is previously mounted on the lower surface of the front end cross member or the side frame for mounting the underguard which is an optional part. It must be welded and fixed, and a reinforcing means is required for the bracket fixed part, and if the underguard is not attached, it will be completely wasted and it will be negative in terms of cost and weight saving of the vehicle body. It has the problem of becoming. Furthermore, in recent years, passenger cars have been designed to lower the lower end of the front skirt on the styling as much as possible, and if a relatively large mounting bracket is projected downward from the lower front body, it is easier to land. It also has the problem of becoming.

The present invention aims to address the above-mentioned conventional problems.

[0006]

[Means for Solving the Problems]

 The present invention originally uses the left and right tie-down hooks that are firmly fixed to the lower parts of the left and right parts of the front body (for example, the left and right side frames), and for example, the left and right end parts of the mounting member made of pipe material are The tie down hook is attached and fixed, the front portion of the underguard is fixed to the attachment member, the rear portion of the underguard is fixed to the vehicle body, and the underguard is attached.

[0007]

[Action]

 As described above, by adopting the structure in which the underguard is attached to the left and right tie-down hooks that are originally firmly fixed to the left and right parts of the front body through the attachment members, the side frame, etc. No special reinforcement for mounting the underguard on the vehicle body or setting of a mounting structure such as a bracket is required. Therefore, it is possible to reduce the weight and cost of the vehicle when the underguard is not attached. When an excessive load is applied to the tie-down hook, the tie-down hook is only damaged, and the side frame and other body frame members are hardly deformed.

[0008]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, 1 is an underguard, 2 is an underguard attachment member, the attachment member 2 is made of a hollow hollow pipe material, and both ends of the attachment member 2 made of the pipe material are on the left and right sides. The left and right tie-down hooks 3 fixed to the frame are attached and fixed by attaching means described later.

As is well known in the art, the tie-down hook 3 has a tie-down hook that is attached to a wheel apron so that a U-shaped hook portion 3a projects downward from the lower end of the side frame. It is firmly fixed by a bracket (for example, see Japanese Utility Model Laid-Open No. 3-55307), and a rope or the like can be inserted and locked in the U-shaped hook portion 3a protruding downward. However, since the specific fixing structure of the tie-down hook 3 to the side frame is conventionally known as described above, illustration and detailed description thereof will be omitted.

The attachment means for attaching and fixing both ends of the attachment member 2 to the left and right tie-down hooks 3, 3 includes an outer plate 22 having one end of the rod 21 fixed by welding or the like, and the rod 21 penetrates the outer plate 22. And an inner plate 23 having a through hole 23a for connecting the outer plate 22 to the outer side of the tie-down hook 3 by penetrating the bar member 21 into the hook portion 3a of the tie-down hook 3. The inner plate 23 is joined to the inner side of the tie-down hook 3 while being inserted into the tip of the rod 21, and the tip of the rod 21 is fitted into the hollow portion from the end of the mounting member 2 made of pipe material. Then, the outer plate 22 and the inner plate 23 are fixed by tightening bolts and nuts, and the substantially U-shaped hook member 4 is passed through the fitting portion between the bar member 21 and the mounting member 2. It is fixed with a nut. In this way, the outer plate 22 and the inner plate 23 are tightened and fixed with the bolts and nuts, so that the outer plate 22 and the inner plate 23 are attached to the outer side of the tie down hook 3 while the rod 21 penetrates the hook portion 3a. By firmly pinching it from the inside, the bar 21 protruding inward from the through hole 23a of the inner plate 23 is fitted into the hollow portion from the end of the mounting member 2, and the fitting portion is fixed by the hook member 4. The attachment member 2 is firmly attached and fixed to the tie-down hook 3. In addition, the insertion hole 21a of the hook member 4 provided in the bar member 21 is configured as an elongated hole that is long in the axial direction, so that the dimensional error in the longitudinal direction of the fitting portion between the bar member 21 and the mounting member 2 is absorbed. However, instead of making the hook portion material insertion hole 21a of the bar member 21 into an elongated hole, the insertion hole 2a of the hook member 4 provided in the attachment member 2 may be formed into an elongated hole elongated in the axial direction. .

In this way, the underguard 1 is attached to the lower side of the mounting member 2 whose left and right ends are fixed to the left and right tie-down hooks 3 and 3, and the two left and right portions of the front part of the underguard 1 are clamped 5, 5. Then, the rear end of the underguard 1 is fixed to the vehicle body 6 such as a cross member or a jack-up plate by bolting or the like to firmly attach the underguard 1 to the vehicle body. It is what is done. In the vehicle with the underguard 1 thus mounted, the left and right hook members 4 for fixing the fitting portion between the bar member 21 and the mounting member 2 are used as hooks for tie-down or towing of the vehicle body. .

[0013]

[Effect of device]

 As described above, according to the present invention, the left and right tie down hooks that are originally firmly fixed to the left and right side frames are used, and the under guard is attached to the tie down hooks via the mounting members. As a result, even if a large under guard is mounted, special reinforcement for mounting the under guard on the vehicle body such as the side frame and setting of the mounting structure such as the bracket are completely unnecessary, and the under guard is not mounted. It is possible to reduce the vehicle weight and cost. Also, when the underguard is attached, it is easy to install and has versatility, so it can be widely used as a mounting structure for optional parts, and the tie-down hook is damaged even when an excessive load is input due to grounding. It also has the advantage that the skeleton members (side frames, etc.) of the vehicle body are hardly deformed only by receiving them, which can bring a great effect in practical use.
