Description

  The present invention relates to a bumper of a vehicle, and more particularly to a structure for attaching a bumper to a body of an automobile.

  Conventionally, a bumper retainer has been set in order to make the gap between a bumper and a lamp such as a tail lamp constant and to improve the accuracy of the gap. Such a bumper retainer can improve the accuracy of the gap between the bumper and the lamp as the relationship with the lamp is closer. For this reason, a so-called lamp-integrated bumper retainer formed integrally with the lamp is provided. Patent Document 1 discloses an example of such a lamp-integrated bumper retainer.

  As shown in FIGS. 3 to 4, the lamp-integrated bumper retainer has a clip-shaped lamp-side locking portion 101 provided integrally with the lamp L on the lower surface of the lamp L, and the lamp-side locking portion 101 and the bumper. By engaging with the bumper side locking portion 102 formed at the upper end of B, the bumper is held just below the lamp L and positioned. A plurality of sets of the lamp side locking portion 101 and the bumper side locking portion 102 are provided at substantially equal intervals. The lamp side locking portion 101 may be formed integrally with the lamp L or may be formed separately and attached to the lower portion of the lamp, but the structure is the same in either case.

  Specifically, the lamp-side locking portion 101 is connected to the upright wall 101a hanging from the lower end of the lamp, the horizontal portion 101b that extends forward from the lower end of the upright wall 101a, and the front end is inclined downward, and horizontally from the lower surface of the lamp L. The locking claw 101c protrudes toward the portion 101b. On the other hand, the bumper side locking portion 102 includes a tongue piece 102a formed at the upper end of the bumper B, and the tongue piece 102a has an engagement hole 102b near the center thereof.

When the bumper B is mounted on the body of the automobile, the tongue piece 102a is inserted into the gap between the lower surface of the lamp L and the horizontal portion 101b, and the locking claw 101c is engaged with the engagement hole 102b, thereby locking the bumper side. The portion 102 is locked to the lamp side locking portion 101, and the bumper B is positioned with respect to the lamp L. For this reason, the gap S between the bumper B and the lamp L can be kept constant.

  However, in an automobile employing such a lamp-integrated bumper retainer, the lamp cannot be removed unless the bumper is removed. This is because if the lamp is moved outwardly of the vehicle, the tongue piece 102a of the bumper side locking portion 102 abuts against the standing wall 101a of the lamp side locking portion 101, and further outward movement is restricted. This is because that.

  Therefore, when removing the lamp L for repair or the like, remove the bumper B from the vehicle in advance, or elastically deform the bumper to release the engagement between the bumper side locking portion 102 and the lamp side locking portion 101, In this state, it was necessary to remove the lamp L. In addition to being troublesome for such work, there is a risk of accidentally damaging the bumper or damaging the bumper retainer.

  The present invention has been made in view of the above problems, and an object thereof is to provide a bumper mounting structure in which a lamp can be attached and detached while the bumper is mounted on a vehicle body.

  In order to achieve the above object, the present invention provides a bumper having a lamp side locking portion provided on a lower surface of a lamp and a bumper side locking portion formed at an upper end of the bumper and detachable from the lamp side locking portion. In the mounting structure, the ramp side latching portion includes a first latching piece continuous to the ramp only in the vehicle width direction, and the bumper side latching portion is continuously provided to the bumper only in the vehicle width direction. It consists of a second locking piece that can be engaged with and disengaged from the first locking piece. From the state in which the lamp side locking part and the bumper side locking part are engaged with each other, either the front or the rear Even when sliding, these engagements are released.

  Each of the lamp side latching portion and the bumper side latching portion is mutually exclusive of either the pair of mail locking pieces projecting outward in the vehicle width direction or the pair of female locking pieces projecting inward in the vehicle width direction. It is desirable to provide.

  It is desirable that the first locking piece and the second locking piece include a positioning mechanism that can be engaged and disengaged with each other.

  The positioning mechanism preferably includes a locking hole and a locking claw that can be elastically engaged with and disengaged from the locking hole.

  According to the bumper mounting structure of the present invention, the first and second locking pieces constituting the ramp side locking portion and the bumper side locking portion are both connected to the ramp and the bumper only in the vehicle width direction. Accordingly, the first and second locking pieces can be slid in the vehicle front-rear direction, and the lamp can be detached while the bumper is mounted on the vehicle body.

  The first locking piece and the second locking piece include a positioning mechanism that can be engaged and disengaged with each other, whereby the bumper can be easily positioned with respect to the lamp.

  When the positioning mechanism includes a locking hole and a locking claw that can be elastically engaged with and disengaged from the locking hole, the first and second locking pieces can be By simply sliding in the direction, the bumper can be easily positioned relative to the ramp and released.

Is configured to be released. The lamp side locking portion 2 may be formed integrally with the lamp L or may be formed separately and attached to the lower portion of the lamp, but the structure is the same in either case.

  Such a configuration is realized by the fact that the locking pieces constituting the ramp side locking portion 2 and the bumper side locking portion 3 are both connected to the ramp and the bumper only in the vehicle width direction. That is, the first and second locking pieces are not connected to the ramp and the bumper in the vehicle front-rear direction, and the obstacles such as the standing wall 101a in the ramp-side locking portion 101 of the conventional example are not connected. Since there is no portion, it is possible to slide forward or backward relatively from the state in which the lamp side locking portion 2 and the bumper side locking portion 3 are engaged.

  More specifically, the lamp side locking portion 2 as the first locking piece has a pair of mail locking pieces 21a and 21b provided on the lower surface of the lamp L and protruding outward in the vehicle width direction. The mail locking pieces 21a and 21b are provided on the left and right standing wall portions 22a and 22b that hang from the lower surface of the lamp L, and the left and right horizontal portions 23a that are connected to the lower ends of the standing wall portions 22a and 22b and project outward in the vehicle width direction. , 23b. The left and right horizontal parts 23a, 23b are provided with locking claws 24a, 24b as positioning mechanisms at the center. The locking claws 24a and 24b are AA cross-sectional mountain-shaped claw members that protrude slightly upward from the upper surfaces of the left and right horizontal portions 23a and 23b, that is, slopes are formed in the vehicle front-rear direction. From the elasticity derived from the material, when pressed downward, it can be elastically deformed up to the same plane as the upper surfaces of the left and right horizontal portions 23a, 23b. The ends of the horizontal portions 23a and 23b are rounded at the front and rear corners in order to avoid interference with standing wall portions 32a and 32b of the bumper side locking portion 3 to be described later, that is, chamfered 25a, 25b, 25c and 25d. .

  On the other hand, the bumper side locking portion 3 as the second locking piece has a pair of female locking pieces 31a and 31b formed at the upper end of the bumper B and protruding inward in the vehicle width direction. The female locking pieces 31a and 31b are provided with left and right standing wall portions 32a and 32b that are suspended from the upper end of the bumper B, and left and right horizontal portions that are connected to the upper ends of the standing wall portions 32a and 32b and project inward in the vehicle width direction. 33a and 33b.
