Description

  The present invention relates to a locking structure for a vehicular outfitting part, and more particularly to a locking structure suitable for locking a plurality of outfitting parts to a limited mounting part on the vehicle body side.

  Various interior and exterior products such as garnish and trim, that is, outfitting parts, are mounted on the outer surface of the body of the vehicle and the interior surface of the vehicle interior such as an automobile for the purpose of obtaining the required appearance, surface shape, and function. For example, a radiator grille, a garnish around a head lamp and a tail lamp, etc. are mounted on the outer surface of the body, and a trim or a garnish is mounted on an instrument panel or a door in the vehicle interior. These outfitting parts are often composed of resin molded products that can be obtained with a desired shape, strength, and texture at a relatively low cost, and a locking structure that uses the elasticity of the resin material is used together for the mounting. There are many cases.

  In Patent Document 1, when attaching a resin radiator grill (fitting part) to a bumper fascia (fitting part) disposed at the front part of a vehicle body, a first unit for positioning the fitting part in the vehicle longitudinal direction with respect to the attachment part. After the joint portion and the second engaging portion that locks the fitting part to the attachment site are arranged at different positions in the vehicle width direction, the first engaging portion performs positioning in the vehicle front-rear direction, and then each member The second engaging portion is engaged by utilizing the bending of. Such a locking structure has a function of temporary fixing prior to final fixing by a screwing member such as a screw, and facilitates fastening work at the time of main fixing, and after the main fixing, It has an auxiliary fixing function that prevents the shift of the parts and maintains the appearance of the mating part.

  By the way, the radiator grille is provided with openings that are divided into small areas in order to prevent the entry of foreign matter into the engine room while introducing outside air into the engine room. A honeycomb louver-like radiator grill having a forward inclination is illustrated. Such a radiator grill has a problem that the space between the radiator grille and the radiator side becomes large on the lower side due to the forward inclination, and the space inside the engine room can be seen through the radiator grille.

  Therefore, it has been studied to provide an inner cover that also serves as a rectifying member that guides the airflow to the radiator and a blindfold around the back side of the radiator grill. However, the back side of the radiator grill that requires a complicated mold Since it is practically difficult to integrally form a shape that causes an undercut on the side, the inner cover is constituted by another member (second fitting part) and is fixed to the bumper fascia together with the radiator grille. There is a need.

  However, the locking structure of the radiator grill is provided in a thin frame around the radiator grill, and it is difficult to add a locking structure of the inner cover to the back side of the radiator grill. If the seating surface is formed by closing a part of the grille opening in order to secure the installation space for the locking structure, the engine performance may be lowered.

  Therefore, a locking structure for the inner cover (second fitting part) that does not require a new installation space is required for the existing locking structure for the radiator grill (first fitting part). Such a locking structure is preferable if it can be set without changing an existing locking structure without an inner cover, and further, a radiator grill with an inner cover and a radiator grill without an inner cover according to specifications. Are set as a common locking structure for each specification.

And the frame portion 20 of the radiator grill 2 are separated from each other. Both side edges of the through hole 23 are defined by both side wall portions 21 b, and the locking pieces 21 are joined to the lower surface (back side) of the frame portion 20 of the radiator grill 2 at the base portion of the both side wall portions 21 b.

  Further, on the lower surface of the frame portion 20 adjacent to the through hole 23 of the locking piece 21, a locking claw 22 (second second) that can lock the locking hole 32 provided in the locking piece 31 of the inner cover 3. (Locking part) is projected. The locking claw 22 has a shape of three ribs oriented along the insertion direction of the locking piece 31 shown in FIG. With this configuration, it is possible to prevent sink marks at the time of molding on the design surface side of the frame portion 20 on which the locking claws 22 are projected, and to ensure strength necessary for locking.

  The locking pieces 31 of the inner cover 3 are juxtaposed along the lower edge of the inner cover 3 in correspondence with the locking pieces 21 (the locking claws 22 and the through holes 23) of the radiator grill 2. , Each projecting forward from the base portion 33 projecting further downward from the lower edge portion of the inner cover 3 toward the corresponding locking portion 22. A locking hole 32 penetrating the distal end portion in the thickness direction is formed at a flat end portion of the locking piece 31, and a rib 34 is extended rearward from the base portion 33. Thus, the base portion 33 of the locking piece 31 is reinforced.

  At the lower edge of the opening 10 of the bumper fascia 1, four attachment portions 11 are arranged side by side corresponding to the locking pieces 21 of the radiator grill 2. Each mounting portion 11 is provided so as to protrude slightly rearward from the opening 10, and a flange 11 a is erected at the edge of the mounting portion 11, and the engaging piece 21 of the radiator grill 2 is engaged through the flange 11 a. A locking hole 12 (first locking portion) that can be stopped is provided.

  When attaching the radiator grill 2 and the inner cover 3 configured as described above to the opening 10 of the bumper fascia 1, first, as shown by an arrow C in FIG. The inner cover 3 is assembled to the rear surface of the radiator grille 2 by being inserted into the through hole 23 of the grill 2 and engaging the engaging hole 32 at the tip of the engaging piece 31 with the engaging claw 22. Thereafter, as shown in FIG. 3, a fastening member such as a screw is inserted into a plurality of holes 35 provided at the peripheral edge of the inner cover 3, and is screwed and fastened to a boss 25 protruding from the rear peripheral edge of the radiator grill 2. Thus, the inner cover 3 is fixed to the radiator grill 2 and integrated.

  Next, as shown by an arrow D in FIG. 7, the locking piece 21 of the radiator grill 2 is inserted into the locking hole 12 of the bumper fascia 1, and the claw portion 21 c of the locking piece 21 is engaged with the edge of the mounting portion 11. By stopping, the radiator grill 2 and the inner cover 3 are locked to the opening 10 of the bumper fascia 1. Furthermore, the radiator grill 2 and the inner cover 3 are attached to the bumper fascia 1 by fixing the upper edge and both side edges of the radiator grill 2 to the bumper fascia 1 with a clip or a screw (not shown).

  With the above configuration, the first locking structure (locking piece 21, locking hole 12) for locking the radiator grille 2 to the bumper fascia 1, and the inner cover 3 for locking the radiator grille 2 are provided. Since the second locking structure (the locking piece 31, the locking claw 22, and the through-hole 23) is arranged in the same place, the installation space can be reduced compared to the case where these locking structures are provided separately. In addition, the respective locking structures are combined to form a reinforcing structure, and the assembling strength can be improved. In particular, due to the configuration in which the locking piece 21 of the radiator grill 2 and the locking piece 31 of the inner cover 3 are linearly arranged, the reaction force in the locking direction is increased in the direction of increasing the locking force of each other. Even when an external force due to deformation or the like is applied, a stable locking force can be obtained.

  In addition, the specification having the inner cover 3 on the back surface of the radiator grill 2 and the specification not having the inner cover 3 can use the first locking structure (the locking piece 21 and the locking hole 12) in common. Even when the inner cover 3 is added to the back surface of the radiator grill 2 due to addition or the like, there is an advantage that the original locking structure (the locking piece 21 and the locking hole 12) can be used as it is.

  Furthermore, the side wall 21b erected on both sides of the locking piece 21 not only reinforces the base of the locking piece 21, but also the side wall 21b connects the locking piece 31 of the inner cover 3 to the through hole 23. It becomes a guide for insertion, and further, the locking piece 31 of the inner cover 3 is moved straightly and engaged with the locking claw 22 in a state where the position in the vertical direction and the width direction is regulated by the side wall portion 21 b and the through hole 23. Therefore, the assembling property is good.

  In the illustrated example, the locking piece 21 of the radiator grille 2 and the locking piece 31 of the inner cover 3 are relatively small but have a crossing angle and project in the opposite direction. It can be locked with the movement to the side, and the assembling property is also good. As shown in FIG. 6, a wedge shape is formed between the rib 34 extending rearward from the base portion 33 of the locking piece 31 of the inner cover 3 and the locking piece 21 of the radiator grill 2 in accordance with the crossing angle. However, the ribs 34 may be extended further downward to be brought into contact with the locking pieces 21 of the radiator grill 2. In this case, the rib (34) serves as a support portion for the locking piece 21, which is advantageous in improving the locking force to the bumper fascia 1.

  In the above-described embodiment, the structure in which the radiator grille 2 (first fitting component) and the inner cover 3 (second fitting component) are locked to the bumper fascia 1 (attachment portion) has been described. The present invention is not limited to the embodiment, and the locking structure of the present invention can also be applied to locking other equipment parts mounted inside and outside the vehicle. Further, based on the technical idea of the present invention. It is added that various modifications and changes are possible.
