Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a structure for closing a hole for draining electrodeposited liquid provided on the lower surface side of a cross member disposed on the lower surface of a vehicle bottom plate.

(Prior art and its problems) In the assembly process of the lower part of a vehicle, a cross member is spot welded to the lower surface of the floor panel that makes up the vehicle bottom plate for reinforcement, and then the floor panel and cross member are electrodeposited. Although the electrodeposition liquid is applied by dipping it into a liquid, there is a risk that the electrodeposition liquid will enter the cross member when it is immersed in the electrodeposition liquid, and the electrodeposition liquid will not come out from inside the cross member. Therefore, a hole for draining the electrodeposited liquid is formed on the underside of the cross member, but if the vehicle is left as is, mud will enter the cross member through the hole for draining the electrodeposited liquid while the vehicle is running, and rust will occur inside the cross member. This will cause this to occur.

Conventionally, in order to overcome this drawback, the holes for draining the electrodeposited liquid have been closed with plugs, but this has the problem that the need for parts increases as the plugs are required, leading to an increase in costs.

(Purpose of the invention) This invention was made to solve the above problem. By blocking the electrodeposited liquid drain hole with a spare tire, the hole on the underside of the cross member of the vehicle eliminates the need for a plug. The purpose is to provide a closing structure.

(Means for Achieving the Object) In order to achieve the above object, the structure for closing the hole on the lower surface of the cross member of the vehicle of this invention is such that a cross member is disposed on the lower surface of the floor panel of the vehicle, and the lower surface of the cross member is In a vehicle having a hole for draining electrodeposited liquid, a spare tire hanger is provided below the cross member, and the hole for draining electrodeposited liquid is connected to the spare tire supported by the spare tire hanger on the lower surface of the cross member. It is formed at the point where it touches.

(Embodiment) FIG. 1 is a perspective view showing the main parts of a vehicle that is an embodiment of this invention, and FIG. 2 is a sectional view taken along the line -- in FIG. 1.

As shown in both figures, a floor panel 1 is arranged on the bottom of the vehicle, cross members 2 are spot-welded to the lower surface of the floor panel 1, and a suitable number (two in this embodiment) are attached to the cross members 2. A hole for draining the electrodeposited liquid is formed. Further, a spare tire hanger 4 is provided below the cross member 2, and both electrodeposited liquid drain holes 3 are formed at locations where the spare tire 5 supported by the spare tire hanger 4 on the lower surface of the cross member 2 contacts. are doing. The spare tire hanger 4 is composed of a hanger body 6 formed by bending a single bar, and a stopper bar 7. The hanger body 6 includes a pair of central portions 6a that support the lower surface of the spare tire 5;
It consists of a base end 6b connected to the floor panel 1 so as to be movable up and down, and a distal end 6c provided between both central parts 6a and connected to the floor panel 1 via a connector (not shown). , the stopper bar 7 is welded to the central portion 6a. Further, rising portions 7a are provided at both ends of the stopper bar 7 to prevent the spare tire 5 from coming off from the top of the hanger body 6.

In the above configuration, with the spare tire hanger 4 rotated downward, the spare tire 5 is placed on the spare tire hanger 4, the tip 6c of the hanger main body 6 is grasped, and the spare tire hanger 4 is rotated upward. When the tip portion 6c is fixed to the floor panel 1 with a connector and the spare tire 5 is attached to the underside of the vehicle, the side surface of the spare tire 5 is pressed against the underside of the cross member 2, and the electrodeposited The drain hole 3 is covered by the spare tire 5. Therefore, even if mud is thrown up while the vehicle is running, the mud will not get into the electrodeposition liquid drain hole 3. Furthermore, since the spare tire 5 is sandwiched between the cross member 2 and the spare tire hanger 4, it does not vibrate on its own while the vehicle is running.

(Effects of the invention) As described above, according to the structure for closing the hole on the lower surface of the cross member of the vehicle of this invention, the hole for draining the electrodeposition liquid of the cross member can be closed to the spare tire supported by the spare tire hanger on the lower surface of the cross member. Since it is formed at the location where the tire contacts, the hole for draining the electrodeposited liquid can be covered by the spare tire supported by the spare tire hanger. Therefore, there is no longer a need for a plug for closing the hole for draining the electrodeposited liquid, which was conventionally required, and the number of parts can be reduced by that much, leading to cost reductions.
