WO-2026094736-A1 - VEHICLE LIGHT FIXTURE

Abstract

Provided is a vehicle light fixture provided with a lamp body that suppresses movement of a cord arranged in a lamp chamber. The present invention includes: a housing cover made of a light-transmissive resin, attached to a front opening of a housing, and forming a lamp chamber; and a cord electrically connected to an electric device arranged in the lamp chamber. On a rear surface wall of the housing, an opening communicating with the outside, and an L-shaped or J-shaped hook provided to project toward the lamp chamber and hooking the cord, are integrally formed. The hook is provided at a position separated from the shortest path of the cord, with an insertion port of the cord set as a direction of the separation with respect to the shortest path.

Description

Vehicle lighting The present invention relates to a vehicle lighting device that uses a hook provided inside the lighting chamber to suppress the movement of a cord placed inside the chamber. Within the lamp housing of a vehicle's lighting fixture, there are wires that connect devices such as light source units and sensors, transmitting signals and power. Because the wires vibrate due to the vehicle's movement, potentially causing damage and breakage, it is desirable to secure them to prevent movement. For example, Patent Document 1 describes a design where a clamp is integrally provided at the lamp body opening to prevent the vertically extending wires from swaying from side to side. This suppresses wire movement without the need for additional fixing members. This shows the arrangement of the vehicle lighting fixture according to the first embodiment.This is a cross-sectional view along the line II-II in Figure 1.This shows the configuration of the vehicle lighting fixture in section A of Figure 1. It mainly shows the lamp body and cord. Figure 3(A) shows the front view. Figure 3(B) shows the perspective view.This shows the mold for the lamp body. It is a cross-sectional view corresponding to line II-II in Figure 1.This is an explanatory diagram illustrating the effects of this configuration. Figure 5(A) shows a conventional configuration for comparison, illustrating a lamp body without a clamp and the wiring of the cord in that lamp body. Figure 5(B) shows the lamp body of this configuration and the wiring of the cord in that lamp body.A modified example is shown. Figure 6(A) is a cross-sectional view of the modified lamp body, corresponding to Figure 2. Figure 6(B) is a cross-sectional view of the mold for the modified lamp body, corresponding to Figure 4.The lamp body and cord of the vehicle lighting device according to the second embodiment are shown. Figure 7 corresponds to Figure 3(B).This is a front view showing the lamp body and cord of a vehicle lighting device according to the second embodiment. Figure 8 corresponds to Figure 3(A).This shows the arrangement of the vehicle lighting equipment according to the third embodiment.Figure 9 shows a part of the configuration of a vehicle lighting fixture. It mainly shows the lamp body and cord. The following describes specific embodiments of the present invention with reference to the drawings. These embodiments are illustrative and not limiting to the invention; not all features or combinations thereof described in the embodiments are necessarily essential to the invention. Furthermore, in the following descriptions of embodiments and modifications, identical components are denoted by the same reference numerals, and redundant explanations are omitted as appropriate. (First Embodiment) Figure 1 shows the arrangement of a vehicle light fixture 1 according to a preferred first embodiment of the present invention. It is a rear view of a vehicle V1 equipped with the vehicle light fixture 1. The vehicle lighting unit 1 is a seamless type rear combination lamp, consisting of a tail lamp (TALE) that extends horizontally in the upper region, a pair of stop lamps (STOP) positioned in the left and right side regions below the tail lamp (TALE), and a pair of turn signal lamps (TURN) positioned below the stop lamps. It is mounted on the rear of the vehicle V1, with the light emission direction facing rearward. A seamless-type lamp is a lamp that, when two independent lamps are installed side by side, presents an appearance as a single lamp, with the seam between the two lamps being inconspicuous. The vehicle lighting unit 1 consists of a pair of outside units (OSU) arranged on the outer side in the vehicle width direction of the vehicle V1, and an inside unit (ISU) arranged in the rear trunk (RT) on the inner side in the vehicle width direction. The outside units (OSU) are equipped with a tail lamp (TALE), a stop lamp (STOP), and a turn signal lamp (TURN). The inside unit (ISU) is equipped only with a tail lamp (TALE). The taillight (TALE) is positioned in both the outside unit (OSU) and the inside unit (ISU). By positioning the outside unit (OSU) and the inside unit (ISU) close together in the left-right direction, the taillight (TALE) is configured to appear as a single, seamless, continuous lamp. The taillight (TALE) is formed in a long, straight line horizontally. The vehicle lighting unit 1 is configured to be long in the vehicle width direction by this taillight (TALE), and is installed occupying the entire length from the left end to the right end of the vehicle body. Although the vehicle light fixture 1 is installed with its light emission direction facing the rear of the vehicle V1, in the following description of the vehicle light fixture 1, the light emission direction of the vehicle light fixture 1 will be described as facing forward. The configuration of this disclosure is not limited to the rear lamps and tail lamps of this embodiment, but can also be
