Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp mounting structure for commercial vehicles such as passenger cars and trucks and industrial vehicles such as construction machines.

[0002]

2. Description of the Related Art Some passenger cars are equipped with a round lamp. In this case, a cylindrical concave portion is formed in a fixed portion such as a front bumper, a rear bumper, and a body,
The round lamp is inserted into the recess, and the mounting portion provided on the lamp is positioned at a predetermined position in the circumferential direction of the recess. Next, there is a configuration in which a screw (an example of a connecting member) is fastened to the mounting portion of the lamp from the back side of the fixing portion, and the lamp is mounted in the concave portion.

[0003]

As described in the prior art, when a round lamp is inserted into a cylindrical recess, the lamp may rotate inside the recess. Accordingly, when the lamp is inserted into the concave portion and the mounting portion of the lamp is positioned at a predetermined position in the circumferential direction of the concave portion (position for connecting the mounting portion of the lamp to the concave portion by the connecting member), the mounting of the lamp is performed. Since the portion is located inside the recess, it is difficult for an operator to visually check whether or not the lamp mounting portion is located at a predetermined position in the circumferential direction of the recess. Therefore, an operator must take the lamp mounting portion into a predetermined position in the circumferential direction of the concave portion while rotating the lamp inserted into the concave portion by hand, and perform an operation of tightening a screw. In this case, if the surface of the fixed portion and the surface (lens) of the lamp are set at substantially the same position (height) depending on the type of vehicle, or if the lamp is set so as to almost completely enter the inside of the concave portion, the above-described case may occur. As described above, the operation of manually rotating the lamp inserted into the concave portion by the operator becomes difficult.

At a predetermined position in the circumferential direction of the concave portion, the mounting hole for the screw is set slightly larger, and even if the mounting portion of the lamp is slightly deviated from the predetermined position in the circumferential direction of the concave portion, It is also conceivable to configure so that a screw can be fastened to the mounting portion of the above. However, with this configuration, the center of the lamp is slightly deviated from the center of the concave portion, and the mounting position of the lamp with respect to the concave portion varies. The present invention provides a lamp mounting structure in which a round lamp is inserted into a cylindrical concave portion formed in a fixing portion, and a mounting portion provided on the lamp is connected to the concave portion via a connecting member. It is an object of the present invention to provide a configuration in which a lamp can be easily positioned when the lamp is inserted into a concave portion.

[0005]

According to a first aspect of the present invention, a round lamp is inserted into a cylindrical recess formed in a fixing portion, and a mounting portion provided on the lamp is inserted into the recess. When connecting via the connecting member, the positioning portion which contacts the mounting portion of the lamp so as to be sandwiched from one side and the other along the circumference of the concave portion and determines the position of the lamp in the circumferential direction of the concave portion is formed by the concave portion. It is provided in.

According to the first aspect of the present invention, the position of the positioning portion of the concave portion corresponds to a predetermined position in the circumferential direction of the concave portion (the position for connecting the mounting portion of the lamp to the concave portion by the connecting member). By doing so, when the lamp is inserted into the concave portion, the mounting portion of the lamp is positioned between the positioning portions of the concave portion, so that the mounting portion of the lamp is positioned at a predetermined position in the circumferential direction of the concave portion. Therefore, the lamp does not rotate inside the recess. Therefore, in this state, the mounting portion of the lamp can be easily connected to the predetermined position in the circumferential direction of the concave portion by the connecting member.

According to the first aspect of the present invention, since the positioning portion of the concave portion directly acts on the mounting portion of the lamp connected to a predetermined position in the circumferential direction of the concave portion, for example, the positioning portion of the concave portion is different from the mounting portion of the lamp. The positioning of the mounting portion of the lamp at a predetermined position in the circumferential direction of the concave portion is performed with higher precision than the configuration in which the positioning portion of the concave portion acts on the lamp portion. Thus, for example, as described in the problem to be solved by the invention, the screw mounting hole is set slightly larger at a predetermined position in the circumferential direction of the concave portion, and the screw is tightened to the mounting portion of the lamp. According to the first aspect of the present invention, the mounting portion of the lamp can be accurately connected to the predetermined position in the circumferential direction of the recess by the connecting member. It is possible to avoid a state in which the center is slightly deviated and the mounting position of the lamp varies with respect to the concave portion.

[II] According to the features of the first aspect, the concave portion is provided with a guide portion for guiding the mounting portion of the lamp between the positioning portions of the concave portion when the lamp is inserted into the concave portion.
Thus, when the lamp is inserted into the recess so that the lamp mounting portion is located between the positioning portions of the concave portion, even if the mounting portion of the lamp is slightly deviated from between the positioning portions of the concave portion, the lamp can be inserted into the concave portion. With insertion, the mounting portion of the lamp is guided between the positioning portions of the concave portion by the guiding portion of the concave portion.

[III] According to the feature of the second aspect, similar to the first aspect, the "action" described in the above [I] and [II] is provided, and in addition, the following "action" is provided. "
It has. According to the feature of claim 2, the interval between the positioning portions of the concave portion is configured to be narrower toward the deeper side of the concave portion, and the lamp is mounted with the mounting portion of the lamp inserted between the positioning portions of the concave portion. As a result, the mounting portion of the lamp is pressed so as to be sandwiched by the positioning portion of the concave portion. Thereby, according to the feature of claim 2, positioning of the mounting portion of the lamp at a predetermined position in the circumferential direction of the concave portion is performed with higher accuracy.
The rattling of the lamp in the circumferential direction of the recess is suppressed by the pressing action of the positioning portion of the recess.

[IV] According to the feature of claim 3, similar to the case of claim 1 or 2, the above-mentioned [I] [II] [III]
And the following "action" in addition to the above. According to the features of claim 3,
The recess is provided with an auxiliary positioning portion that comes into contact with the recess in the radial direction and determines the position of the lamp in the radial direction of the recess, and when the lamp is inserted into the recess, the mounting portion of the lamp assists the recess. It will be in the state pressed by the positioning part. According to the third aspect of the present invention, when the mounting portion of the lamp is positioned at a predetermined position in the circumferential direction of the concave portion, the position of the mounting portion of the lamp in the radial direction of the concave portion is also positioned. Connecting the mounting portion of the lamp to a predetermined position in the circumferential direction of the concave portion by the member can be further easily performed. In this case, since the auxiliary positioning portion of the concave portion directly acts on the mounting portion of the lamp, for example, compared to a configuration in which the auxiliary positioning portion of the concave portion operates on a portion of the lamp different from the mounting portion of the lamp, the radial direction of the concave portion The position of the mounting portion of the lamp is accurately positioned. Further, rattling of the lamp in the radial direction of the concave portion is suppressed by the pressing action of the auxiliary positioning portion of the concave portion.
