Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a structure for attaching automotive lighting equipment to the exterior panels of the car body, and in particular, it is a simple structure suitable for attaching small and lightweight lighting equipment. This relates to the mounting structure.

[Prior Art] FIG. 2 is a rear view showing an example of a compact and lightweight automobile lamp equipped with a conventional mounting structure, and the light source is drawn perpendicular to the plane of the paper. X-X and Y-Y are orthogonal axes that are orthogonal to the optical axis. That X
-X section is shown in Figure 3, and its Y-Y section is shown in Figure 4.
As shown in the figure. However, the locations where light fixtures are attached to the exterior panels of automobiles are not necessarily flat, and often have a gentle curve. Therefore, the three orthogonal axes X, Y, and Z in the present invention are not orthogonal coordinate axes in the strict sense of three-dimensional geometry, but for convenience of explanation, the three orthogonal axes X, Y, and Z are
It means before and after.

Reference numeral 1 shown in FIG. 3 is a socket, the main body portion 1a of which is inserted into a mounting opening 3 provided in a vehicle body exterior plate 2.

Reference numeral 4 denotes a flange-shaped portion integrally formed on the socket body, which is attached in close contact with the vehicle body exterior plate 2 and supports the bowl-shaped front lens 5. 6 is a light source bulb (omitted in FIG. 4).

In order to attach the socket body part 1a to the vehicle body exterior plate, a pair of protrusions 7a and 7b facing each other in the X direction are provided as shown in FIG. The exterior plate 2 (more specifically, the edge of the opening 3) is held between them.

Of the pair of projections 7a and 7b, 7a is an elastic projection that is supported elastically, and 7b is a fixed projection that is fixedly provided. The elastic protrusion 7a
is formed at the tip of a leaf spring-like member 8 integrally molded with the socket main body 1a.

By bending the leaf spring-like member 8, the socket 1
can be easily attached to the exterior plate opening 3, and the elastic restoring force of the plate spring-like member 8 allows the attachment to be carried out without wobbling in the X direction.

[Problems to be solved by the invention] In the conventional example, as described with reference to FIG. 3, it is installed without play in the X direction, but as can be easily understood from FIG. 4, there is no elasticity in the Y direction. There is no component that automatically removes looseness.

For this reason, in current practice, the clearance between the socket body 1 and the exterior plate opening 3 is set to a slightly negative value (the tolerance is set on the side where the clearance decreases), and the clearance between the socket body 1 The sides of the parts are cut to match the actual parts and fit together. This requires a great deal of time and effort.

This idea was created in view of the above circumstances.
To provide a mounting structure that can be quickly and easily attached to a plate-like part of a vehicle body and does not cause looseness in any direction along the plate surface of the plate-like part.

[Means for Solving the Problems] The structure of the present invention created to achieve the above object includes a socket for a light source bulb that is inserted through an opening provided in a plate-shaped portion of the vehicle body, and A flange-like part that is integrally connected to the socket and attached in close contact with the outer surface of the plate-like part of the vehicle body, and a bowl-shaped lens that is attached to cover the flange-like part, and the flange of the socket A pair of protrusions for sandwiching the plate-shaped part of the vehicle body are provided between the plate-shaped part, and at least one of the pair of protrusions has a plate spring whose base part is integrally connected to the socket. In the mounting structure for an automobile lamp, which is formed at the tip of a shaped member, the direction in which the pair of projections face each other is defined as X, and the direction perpendicular to the X direction and parallel to the plate-shaped part of the vehicle body is defined as As Y, the base portion of a leaf spring-like member whose tip portion can be bent in the Y direction is integrally fixed to the socket.

[Operation] According to the above configuration, when the vicinity of the tip of the leaf spring-like member that can be bent in the Y direction is brought into contact with the plate-like part of the vehicle body, and a pressing force is applied to the abutting part by its elastic force. , the backlash in the Y direction is automatically removed.

[Embodiment] FIG. 1 is a sectional view of a vehicle lamp equipped with an embodiment of the mounting structure according to the present invention.

This embodiment is an improvement by applying the present invention to the conventional example shown in FIG. It is a part.

Next, the points different from the conventional example will be explained.

On both sides of the socket main body 1a in the Y direction,
Cuts 9 are provided from the front end side (left side in the figure), respectively, to form a leaf spring-like portion 10.

Near the front end of the socket body 1, the Y
The width dimension W in the direction is set in advance to be larger than the inner dimension in the Y direction of the opening 3 of the exterior plate. As a result, the tips of the leaf spring-like portions 10 are bent inward in the Y direction, and the elastic restoring force presses against the edge of the opening 3 to remove looseness.

[Effects of the invention] As detailed above, the automobile lamp equipped with the mounting structure according to the invention can be quickly and easily attached to the plate-like member of the vehicle body, and the above-mentioned plate-like member can be mounted quickly and easily. No play occurs in any direction along the plate surface.
