[ And an escape prevention clip (50) for preventing the escape of the downward detent.

The vehicle is provided with a tank body for storing fluid such as fuel, urea water, etc., and a mounting bracket 10 is provided to fix the tank body to the vehicle body.

Here, the mounting bracket 10 is provided such that the rear surface 12 is fixed to the tank body and the upper surface 16 is fastened to the vehicle body bolt 60 through the bolt 60. Thus, the tank body is fixed to the vehicle body bolt 60 So that it can be coupled to the vehicle body.

At this time, the upper surface 16 of the mounting bracket 10 is provided with a through-hole through which the body bolt 60 passes, and the first bush 20 made of a polymer compound is fitted in the through-hole.

That is, since the bolt 60 of the vehicle body is coupled to the mounting bracket 10 with the first bush 20 of elastic material interposed therebetween, the impact generated during the running of the vehicle body is directly transmitted to the mounting bracket 10 Can be prevented. Particularly, since the first bush 20 is made of a polymer compound material, the impact transmitted to the mounting bracket 10 can be damped, thereby preventing the mounting bracket 10 or the tank body from being damaged.

In the present invention, the first bush 20 is formed in a columnar shape and is provided to include the first hollow 22, and the first hollow 22 is provided so as to be fitted with the second bush 30. Here, the second bush 30 is made of a metal material so that sufficient rigidity can be secured when the body bolt 60 is coupled to the mounting bracket 10.

In the present invention, reinforcing rib portions 40 are protruded toward the inner space 18 on both side surfaces 14 of the mounting bracket 10, and are protruded from the downward point of the second bush 30.

In the reinforcing rib portion 40, a release-preventing clip 50 is seated and slidable. That is, after the maker seats the separation prevention clip 50 on the reinforcing rib portion 40, the separation prevention clip 50 is inserted into the inner space 18 of the mounting bracket 10 so as to slide along the reinforcing rib portion 40, The separation preventing clip 50 can be inserted between the second bush 30 and the reinforcing rib portion 40. [

Here, the bolt hole 52 is formed at the corresponding position of the release-preventing clip 50, so that the bolt 60 of the vehicle body is to be penetrated. The bolt hole 52 may be made of a metal material to secure rigidity.

When the separation preventing clip 50 is sandwiched between the second bush 30 and the reinforcing rib portion 40 as described above, the vehicle body side bolt 60 is fastened in the state in which the vehicle body and the mounting bracket 10 are not aligned, The second bush 30 can not be separated from the first bush 20 by the escape prevention clip 50 even if the body bolt 60 presses the second bush 30 downward.

Therefore, since the second bush 30 can be normally aligned and assembled without being separated from the first bush 20, the assembling performance between the mounting bracket 10 and the vehicle body can be effectively improved.

In order to facilitate understanding, the bolt 60 of the vehicle body is provided with a stud bolt and the mounting nut is assembled to the lower side of the body bolt 60, so that the mounting bracket 10 can be assembled to the vehicle body.

In the present invention, the mounting bracket 10 is formed to have a front opening. The reinforcing rib portion 40 extends along the front-rear direction of the mounting bracket 10, And is sandwiched between the second bush 30 and the reinforcing rib portion 40 while being guided from the front side to the rear side.

That is, when the manufacturer intends to insert the detachment prevention clip 50 into the inner space 18 of the mounting bracket 10, the detachment prevention clip 50 is seated on the reinforcing rib portion 40, The release-preventing clip 50 can be assembled.

The reinforcing rib portion 40 may extend along the front and rear directions on both side surfaces 14 of the mounting bracket 10 so as to extend over the rear surface 12 of the mounting bracket 10.

The rigidity of the mounting bracket 10 is increased by extending the reinforcing rib portion 40 from the rear face 12 and both side faces 14 of the mounting bracket 10 toward the inner space 18 as shown in FIG. The sliding of the departure prevention clip 50 can be guided.

The release-preventing clip 50 is press-molded and formed into a flat plate shape so as to be insertable into the inner space 18 of the mounting bracket 10 and has guide flanges 54 may be formed by bending.

That is, as shown in FIG. 2, the release preventing clip 50 is manufactured by performing a pressing process to form the bolt hole 52 and the guide flange 54 on the flat plate material.

Particularly, the release-preventing clip 50 has the guide flange 54 bent at the both ends thereof to be seated on the reinforcing rib portion 40 so that the release-preventing clip 50 can be attached to the mounting bracket 10 along the reinforcing rib portion 40, As shown in FIG.

Here, the guide flange 54 may be formed so as to extend while covering the inner side surface and the upper side surface of the reinforcing rib portion 40.

That is, as shown in FIG. 2, the guide flange 54 of the release-preventing clip 50 may be formed in a shape that is bent downward as it goes toward the end, and is flattened after partially returning upward.

This is to prevent the phenomenon that the release-preventing clip 50 is shaken in the left-right direction when the release-preventing clip 50 is seated on the reinforcing rib portion 40 through the guide flange 54.

Further, the guide flange 54 is projected downward from an area covering the upper surface of the reinforcing rib portion 40 to abut the upper surface of the reinforcing rib portion 40, so that when the release preventing clip 50 is detached, A separation preventing portion 56 for providing a frictional force to the upper surface of the rib portion 40 may be formed.

1 to 3, the guide flange 54 of the release-preventing clip 50 is provided with an elongated slanting extension 56 to abut the upper surface of the reinforcing rib portion 40 to provide a frictional force .

Specifically, the release preventing portion 56 is formed so that a part of the region of the guide flange 54 that covers the upper side of the reinforcing rib portion 40 is cut and bent downward, and as the front side of the mounting bracket 10, And the lowermost end thereof is in contact with the upper surface of the reinforcing rib portion 40. In this case,

3, when the separation prevention clip 50 is pulled in front of the mounting bracket 10, the lowermost end of the separation preventing portion 56 does not apply a frictional force to the reinforcing rib portion 40, The separation preventing clip 50 can be moved.

However, when the separation preventing clip 50 receives a force in a direction in which the separation preventing clip 50 is drawn out from the mounting bracket 10, the lowermost end of the separation preventing portion 56 is in contact with the upper surface of the reinforcing rib portion 40 The resisting force is generated when the escape prevention clip 50 comes out of the mounting bracket 10 because the force to fix the escape preventing clip 50 to the mounting bracket 10 is applied.

As a result, in the process of preventing the second bush 30 from being separated from the second bush 30 through the first braking clip 50, it is possible to prevent the second bush 30 from being detached together with the escape prevention clip 50 being detached from the mounting bracket 10 As a result, the durability of the mounting device for a vehicle tank can be secured.

In addition, since the separation preventing portion 56 is formed by cutting a part of the guide flange 54, it is possible to effectively prevent the separation preventing clip 50 from being detached from the mounting bracket 10 without adding a separate device .

Meanwhile, the guide flange 54 may be bent upward so that the end portions of the guide flange 54 are parallel to both side surfaces 14 of the mounting bracket 10.

Therefore, it is possible to prevent the side surfaces 14 of the mounting bracket 10 from being stuck or scratched by the guide flange 54 when the release-preventing clip 50 is seated and guided by the reinforcing rib portion 40, 10 can be improved in durability.

In addition, the release-preventing clip 50 is formed such that the front end portion 58 is bent so as to bend upward, so that when the maker pushes the release-preventing clip 50 into the inner space 18 of the mounting bracket 10, Can be prevented.

That is, the manufacturer assemble the release-preventing clip 50 by pushing the release-prevention clip 50 toward the front side of the mounting bracket 10. The release-preventing clip 50 is pressed into a flat plate shape. If the front end portion is flat, Because the contact area is small, it can cause pain in the hand.

Therefore, by forming the front end portion 58 of the release-preventing clip 50 so as to be bent upward, it is possible to sufficiently secure the portion of the maker's hand which is in contact with the hand, thereby preventing injury during assembly of the release-

The release preventing clip 50 is formed such that the rear end portion 59 is bent downward so that when the release preventing clip 50 is inserted into the inner space 18 of the mounting bracket 10, The rear end portion 59 of the mounting bracket 50 abuts against the rear surface 12 of the mounting bracket 10 and is stopped.

That is, when the release-preventing clip 50 is inserted into the mounting bracket 10 by the manufacturer, it is important that the through-hole of the mounting bracket 10 and the bolt hole 52 of the release-preventing clip 50 are aligned.

Thus, the rear end portion 59 of the release-preventing clip 50 is bent downward to secure an area in contact with the rear surface 12 of the mounting bracket 10, It can serve as a stopper to be completed.

Here, it is preferable that the rear end portion 59 of the departure prevention clip 50 is bent downward because it may interfere with the second bush 30 during the assembling process when it is bent upward.

According to the mounting apparatus for a vehicle tank having the above-described structure, even if the bolts of the vehicle body are attempted to be tightened while the mounting brackets are not properly aligned during the process of joining the tank body to the vehicle body, It is possible to prevent the bushes from being detached from the mounting brackets, thereby improving the durability and assemblability of the products.
