  However, the back door often has a small space for mounting the lamp housing. Therefore, it is difficult to provide a structure for assembling the lamp housing so as not to appear in appearance. Moreover, if the shape of the lamp housing is complicated, it may be difficult to mold the lamp housing. Further, when an assembly part such as a bolt is used for the assembly, a part for attaching the assembly part to the lamp housing is required. Therefore, the lamp housing is increased in size and design, and the assembling work is complicated.

  In addition, the vehicle is frequently subjected to shock and vibration during traveling. Therefore, in the technique described in Patent Document 1, there is a possibility that the position of the vehicular lamp is shifted or detached due to the elastic member.

  In view of such problems, the present invention provides a lamp housing assembly structure that realizes a lamp housing that can be easily and firmly assembled to a back door while being firmly assembled and can be downsized without impairing design. The purpose is to do.

  In order to solve the above problems, a typical structure of a lamp housing assembly structure according to the present invention includes a back door at the rear of a vehicle and a lamp housing that accommodates the lamp and is assembled to the back door. In a lamp housing assembly structure in which the front surface of the mounting portion faces the back door and the lamp is mounted on the rear surface of the mounting portion, the bracket is composed of a long bracket and an elastic body. A fulcrum member that is rotatably supported between and attached to the front surface of the mounting portion in a seesaw shape, the fulcrum member biases the bracket, and makes one end of the bracket with the fulcrum member as a boundary contact the lamp housing, The other end is close to the back door, and the back door is bracketed when the lamp housing is pressed against the back door. And having between the stopper pushing back the other end, the one end of the bracket by sliding in a pressed against the lamp housing pressed against the direction different directions be freed and interfere locking piece.

  According to the above configuration, when the lamp housing is pressed against a predetermined position of the back door, the other end of the bracket near the back door is pushed back by the stopper. At the same time, one end of the bracket with the fulcrum member as a boundary moves away from the lamp housing that has been in contact, and approaches the back door. After that, when the lamp housing is released by sliding in a direction different from the direction in which the lamp housing is pressed against the back door, one end of the bracket tries to return toward the lamp housing again by the urging force of the fulcrum member, and interferes with the locking piece on the way. To do. Thereby, the lamp housing is assembled to the back door.

  Therefore, according to the present invention, the lamp housing can be easily assembled to the back door only by the work from the outside of the vehicle by sliding the lamp housing against the back door. Moreover, according to this invention, attachment parts, such as a volt | bolt which assemble | attaches a lamp housing to a back door, are not required. For this reason, it is not necessary to provide a part for a mounting part in the lamp housing, and the lamp housing can be reduced in size. In addition, since the member for assembling the lamp housing such as the bracket to the back door is provided on the front surface behind the rear surface of the mounting portion to which the lamp is mounted, the light emitted from the lamp is not blocked. Furthermore, since the assembly structure does not appear on the appearance, the design of the lamp housing is not impaired. In addition, since the bracket is pivotally supported at a position very close to the lamp as a lamp mounting portion, the lamp is firmly assembled and stable, and the lamp can be prevented from shaking.

  The lamp housing assembly structure further includes a water stop member made of an elastic body attached to the lamp housing, and the water stop member is pressed against a surface of the locking piece opposite to a surface that contacts one end of the bracket. Good.

  According to the above configuration, the water stop member can prevent fluid such as water from entering the gap between the lamp housing and the back door. The water stop member made of an elastic body is pressed against the locking piece when the lamp housing is assembled to the back door, and urges the locking piece toward the back door. For this reason, the locking piece is sandwiched between one end of the bracket and the water stop member and is urged from both directions, so that the lamp housing can be firmly assembled to the back door.

  The end of the locking piece may be bent toward a bracket that interferes with the locking piece. According to such a configuration, when the lamp housing assembled to the back door is slid in the direction of removing, the one end of the bracket interferes with the bent end of the locking piece. Therefore, the bracket is difficult to come off from the locking piece, and the lamp housing is hard to come off from the back door.

FIG. 3 shows a state in which the lamp housing 110 is pushed into the back door 104 in the direction indicated by the arrow 145 in FIG. 2 and then slid to the outside of the vehicle indicated by the arrow 147 in FIG. FIG. 4 shows a state in which the lamp housing 110 is subsequently released. Hereinafter, a method of assembling the lamp housing 110 in the present embodiment to the back door 104 will be described.

  As shown in FIG. 3, the back door 104 has a stopper 146 and a locking piece 150. When the lamp housing 110 is pressed from the rear to a predetermined position of the back door 104 as indicated by an arrow 145 in FIG. 2, as shown in FIG. End 126 is pushed back. At the same time, one end 124 of the bracket 120 moves away from the abutted lamp housing 110 and approaches the back door 104 as indicated by an arrow 149.

  Thereafter, the lamp housing 110 is slid to the outside of the vehicle in the direction of the arrow 147 different from the direction of the arrow 145 in FIG. When the lamp housing 110 is released as shown in FIG. 4, the bracket 120 having the other end 126 in contact with the stopper 146 is rotated by the urging force of the fulcrum member 122, so that the lamp housing 110 is a vehicle indicated by an arrow 153. Move slightly backwards. On the other hand, one end 124 of the bracket 120 tries to return toward the lamp housing 110 again by the urging force of the fulcrum member 122 as indicated by an arrow 151. On the way, one end 124 of the bracket 120 interferes with a locking piece 150 provided on the back door 104. Thereby, the lamp housing 110 is assembled to the back door 104.

  Therefore, according to the present embodiment, the lamp housing 110 is easily assembled to the back door 104 only by the work from the outside of the vehicle by sliding the lamp housing 110 against the back door 104 toward the front of the vehicle and then sliding it outward. It can be attached.

  In this embodiment, the lamp housing 110 is slid to the outside of the vehicle after being pushed in. However, the present invention is not limited to this, and the sliding direction is configured to move in any direction such as the inside, the upper side, or the lower side of the vehicle. Also good.

  Moreover, according to this embodiment, attachment parts, such as a volt | bolt which assembles the lamp housing 110 to the back door 104, are not required. Therefore, it is not necessary to provide a part for mounting parts in the lamp housing 110, and the lamp housing 110 can be downsized.

  Further, according to the present embodiment, the member for assembling the lamp housing 110 such as the bracket 120 to the back door 104 is provided on the front surface behind the rear surface of the mounting portion 130 to which the lamp 106 is attached. The light is not blocked. Furthermore, since the structure to be assembled does not appear on the appearance, the design of the lamp housing 110 is not impaired. In addition, since the bracket 120 is pivotally supported at a position very close to the lamp 106, which is the mounting portion 130 of the lamp 106, the lamp 106 is firmly assembled and stabilized, and the lamp 106 is prevented from shaking.

  As shown in FIG. 4, the end 152 of the locking piece 150 is bent toward one end 124 of the bracket 120 that interferes with the locking piece 150. Accordingly, when the lamp housing 110 assembled to the back door 104 is slid in the direction of removing, the one end 124 of the bracket 120 interferes with the bent end portion 152 of the locking piece 150. Therefore, the one end 124 of the bracket 120 is difficult to be detached from the locking piece 150, and the lamp housing 110 is difficult to be detached from the back door 104.

  As shown in FIG. 4, when the assembly is completed, one water stop member 140 is pressed against the surface of the locking piece 150 opposite to the surface contacting the one end 124 of the bracket 120, and the other stop The water member 142 is in pressure contact with the back door 104. Therefore, the water stop members 140 and 142 prevent water and other fluids from entering the gap between the lamp housing 110 and the back door 104.

  The water stop members 140 and 142 are made of an elastic body. Therefore, when the lamp housing 110 is assembled to the back door 104, the water stop member 140 is pressed against the locking piece 150 and biases the locking piece 150 toward the back door 104. Therefore, the locking piece 150 is sandwiched between the one end 124 of the bracket 120 and the water stop member 140 and is urged from both directions, so that the lamp housing 110 is firmly assembled to the back door 104.

  Here, a supplementary explanation will be given with respect to FIG. When the lamp housing 110 is released, it has already been described that the lamp housing 110 moves slightly toward the rear of the vehicle indicated by the arrow 153 because the other end 126 of the bracket 120 is in contact with the stopper 146. At this time, the lamp housing 110 also moves to the rear of the vehicle indicated by the arrow 153 by restoring the water-stop members 140 and 142 that have been in pressure contact. This is why the other end 126 of the bracket 120 is separated from the stopper 146, as shown in FIG.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns.
