JP-A-8-121441

  When a mounting part is mounted in a vehicle interior using a clip described in Japanese Patent Application Laid-Open No. 8-121441, if a load in the direction of separation acts on the mounting part in the event of a vehicle collision, the mounting part is attached to the panel. There is a possibility of jumping out of the hole and hitting a passenger in the passenger compartment.

  The above inconvenience can be avoided to some extent by increasing the engagement force of the elastic engagement piece with respect to the mounting hole of the panel, but it cannot be avoided reliably, and if the engagement force of the elastic engagement piece is increased. The mounting workability of the mounting parts will be impaired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to reliably restrict the movement of the mounting component when it is detached without impairing the mounting workability.

  In order to achieve the above object, the present invention engages the engaged portion of the mating panel by moving the engaging portion on the back surface side of the mounting component close to the front surface side of the mating panel along a predetermined mounting direction. By doing so, it is the attachment structure which attaches the said attachment component to the said other party panel, Comprising: A metal stopper bracket and a through-hole are provided.

  The stopper bracket includes a fixed portion that is fixed to the back surface side of the mounting component, a substrate portion that extends from the fixed portion in the mounting direction and protrudes to the back surface side of the mounting component, and a locking plate portion that is bent from the substrate portion. Have The through hole is formed in the mating panel corresponding to the stopper bracket.

  The locking plate part has a first locking piece and a second locking piece. The first locking piece protrudes to the one surface side of the board portion and extends in a direction close to the attachment component. The second locking piece protrudes on the other surface side of the substrate portion and extends in a direction away from the attachment component. The first locking piece and the second locking piece have a flat plate shape that is inclined with respect to the substrate portion as a whole.

  The engaging part engages with the engaged part in a state where the locking plate part is inserted through the through hole and located on the back side of the counterpart panel. The tip of the first locking piece faces the back surface of the mating panel in a state where the engaging portion and the engaged portion are engaged.

  When the load in the anti-attachment direction away from the mating panel acts on the attachment part, the engagement between the engaging part and the engaged part is released and the attachment part moves in the anti-attachment direction. The leading end abuts against the back surface of the mating panel, the locking plate portion is tilted and deformed with respect to the substrate portion by the action of the load, and the tilting deformation of the locking plate portion causes the leading end portion of the second locking piece to Abutting against the back surface, the contact of the first locking piece and the second locking piece with the back surface of the mating panel prevents movement of the mounting component in the anti-mounting direction.

  In the above configuration, when the mounting part is attached to the mating panel, the back side of the mounting part is placed opposite to the front side of the mating panel, and the stopper plate of the stopper bracket is inserted through the through hole of the mating panel. After being positioned on the back surface side, the engaging part of the attachment component is moved close to the surface side of the mating panel along the attachment direction to engage with the engaged part.

  In addition, a load in the opposite mounting direction acts on the mounting part attached to the mating panel, the engagement between the engaging portion and the engaged portion is released, and the mounting part moves in the counter mounting direction from the mating panel. Then, the tip of the first locking piece comes into contact with the back surface of the counterpart panel. When the applied load is relatively small, the contact of the tip of the first locking piece and the back surface of the mating panel prevents movement of the mounting component in the opposite mounting direction, and the mounting component is detached from the mating panel. Is prevented.

  On the other hand, if the acting load is excessive, the locking plate portion is tilted and deformed with respect to the substrate portion, and the tip portion of the second locking piece comes into contact with the back surface of the counterpart panel due to the tilting deformation of the locking plate portion, The contact of the first locking piece and the second locking piece with the back surface of the mating panel prevents movement of the mounting component in the anti-mounting direction, thereby preventing the mounting component from being detached from the mating panel.

  As described above, when the mounting component is mounted, the engaging plate is inserted into the through hole after the locking plate portion of the stopper bracket is inserted into the through hole, so that the engaging operation is inhibited by the stopper bracket. There is no problem and workability is good.

  In addition, when a load in the direction opposite to the mounting direction is applied to the mounting part attached to the mating panel, the stopper plate of the stopper bracket can reliably prevent the mounting part from being detached from the mating panel. it can.

  According to the present invention, it is possible to reliably regulate the movement of the mounting component when it is detached without impairing the mounting workability.

The panel connecting portion 5 includes a pair of outer plate portions 6 that protrude opposite to each other from the back surface of the attachment component 1, and a plate-like attachment portion (not shown) that connects intermediate portions of the outer plate portions 6. The panel connection part 5 has an H-shaped cross section as a whole, and the clip 4 is held by the plate-like attachment part. The mating panel 2 has an H-shaped engagement hole (engaged portion) 4 corresponding to the panel connecting portion 5.

  With the locking plate portion 13 of the stopper bracket 10 to be described later inserted through the through hole 19 of the mating panel 2 and positioned on the back side of the mating panel 2, the mounting component 1 is moved along the predetermined mounting direction 50 in the mating panel 2. When the engagement part 3 is inserted into the engagement hole 7 and the attachment part 1 is pressed in the attachment direction 50, the clip 4 is elastically deformed and is inserted through the engagement hole 7 to move to the mating panel 2. Engage with the peripheral edge of the engagement hole 7 on the back side. Due to the engagement between the clip 4 and the peripheral edge of the engagement hole 7, the movement of the attachment component 1 in the anti-attachment direction 51 that is separated from the counterpart panel 2 is restricted. Further, the movement of the attachment component 1 in the vertical direction and the left-right direction is restricted by the engagement between the panel connecting portion 5 and the engagement hole 7, and thereby the attachment component 1 is attached to and held by the counterpart panel 2.

  As shown in FIGS. 1 and 2, a stopper bracket 10 is provided between two adjacent engaging portions 3 on the back surface side of the attachment part 1. The stopper bracket 10 has a fixed portion 11, a substrate portion 12, and a locking plate portion 13, and is formed by punching a metal plate into an L shape and bending it.

  Two fitting holes 14 that are spaced apart in the vehicle width direction are formed in the fixed portion 11, and two columnar fitting protrusions 15 that correspond to the fitting holes 14 are formed on the back surface of the mounting part 1. Yes. By fitting the fitting hole 14 to the outer peripheral surface of the fitting protrusion 15, the fixing portion 11 is fixed to the back surface side of the attachment component 1. In addition, the method of fixing the fixing | fixed part 11 to the attachment component 1 is not limited above, For example, various methods, such as fastening and fixing with a volt | bolt, are applicable.

  The substrate portion 12 is bent from the fixed portion 11 and extends linearly in the attachment direction 50, and protrudes higher than the engagement portion 3 from the back surface of the attachment component 1. A notch groove 16 is formed on the front end side of the substrate portion 12. The notch groove 16 is U-shaped with the fixed portion 11 side as a bottom, and the locking plate portion 13 is bent at the distal end side of the notch groove 16.

  The locking plate portion 13 has a first locking piece 17 and a second locking piece 18. The first locking piece 17 is bent from the board portion 12 on both sides of the notch groove 16, protrudes to one surface side (lower surface side in the drawing) of the board portion 12, and extends in a direction close to the attachment component 1. The second locking piece 18 is a region defined by the notch groove 16, and stands up by bending the first locking piece 17 from the substrate portion 12, and is provided on the other surface side (upper surface side in the drawing). ) To extend away from the mounting part 1. That is, the first locking piece 17 and the second locking piece 18 have a flat plate shape that is inclined with respect to the substrate portion 12 as a whole.

  As shown in FIGS. 1 and 3, a rectangular through hole 19 is formed in the mating panel 2 so as to correspond to the stopper bracket 10. The width D in the vertical direction of the through hole 19 is set to be larger than the distance L1 between both ends of the locking plate portion 13 in the direction orthogonal to the substrate portion 12 (L1 <D), and the entire length of the locking plate portion 13 ( The length along the inclination direction) is set smaller than L2 (D <L2). The front end portion (lower end) of the first locking piece 17 faces the back surface of the mating panel 2 in a state where the engaging portion 3 and the engaging hole 7 are engaged. That is, in a state where the engaging portion 3 and the engaging hole 7 are engaged, the extension line 53 extending in parallel with the substrate portion 12 from the lower end of the first locking piece 17 intersects the back surface of the counterpart panel 2.

  When attaching the attachment part 1 to the mating panel 2, the back side of the attachment part 1 is disposed opposite to the front side of the mating panel 2, and the locking plate portion 13 of the stopper bracket 10 is inserted into the through hole 19 of the mating panel 2. Then, the engagement portion 3 of the attachment component 1 is moved close to the surface side of the counterpart panel 2 along the attachment direction 50 and is engaged with the engagement hole 17.

  In addition, a load in the anti-attachment direction 51 acts on the attachment part 1 at the time of a vehicle collision or the like, the engagement between the engagement portion 3 and the engagement hole 7 is released, and the attachment part 1 is removed from the counterpart panel 2 in the anti-attachment direction. When moved to 51, as shown in FIG. 4, the tip of the first locking piece 17 comes into contact with the back surface of the counterpart panel 2. When the acting load is relatively small, the movement of the attachment component 1 in the anti-attachment direction 51 is prevented by the contact between the front end portion of the first locking piece 17 and the back surface of the counterpart panel 2, and from the counterpart panel 2. The attachment part 1 is prevented from being detached.

  On the other hand, if the acting load is excessive, as shown by a two-dot chain line in FIG. 4, the locking plate portion 13 is tilted and deformed with respect to the substrate portion 12, and the second engagement is caused by the tilting deformation of the locking plate portion 13. The tip of the stop piece 18 comes into contact with the back surface of the counterpart panel 2. That is, the first locking piece 17 and the second locking piece 18 are in contact with the back surface of the mating panel 2 on both sides of the board portion 12, and the movement of the mounting component 1 in the anti-mounting direction 51 is prevented. The detachment of the mounting part 1 from the panel 2 is prevented.

  When the load is applied, a tensile force is applied to the fixed portion 11 from the substrate portion 12, but this tensile force acts on the fitting portion between the fitting hole 14 and the fitting protrusion 15 as a moment. The fitting state between the two is firmly held, and the stopper bracket 10 is not detached from the mounting part 1.

  As described above, when the mounting component 1 is attached, the engaging portion 3 is engaged with the engaging hole 7 after the locking plate portion 13 of the stopper bracket 10 is inserted into the through hole 19. Combined work is not hindered and workability is good.

  Further, when a load in the counter-mounting direction 51 is applied to the mounting part 1 attached to the mating panel 2, the mounting part 1 is detached from the mating panel 2 by the locking plate portion 13 of the stopper bracket 10. Can be reliably prevented.
