Abstract

[Problem] To provide a vehicle lighting fixture and a method for assembling a vehicle lighting fixture that allows the seal material to easily maintain its annular shape within the seal groove when the projection of the lens is press-fitted into the elongated seal material placed in the annular seal groove formed in the housing, and that facilitates assembly. [Solution] The sealing material 60, which is attached to the housing 22 provided on the vehicle body, has a main body portion 64 located between both ends and arranged in an annular shape throughout the sealing groove 24, one end portion 61 located in the first communication portion 35 and the end storage space 29, and the other end portion 62 whose circumferential position in at least a part of the sealing groove is the same as that of the first communication portion.

Description

This invention relates to a vehicle lighting fixture and a method for assembling a vehicle lighting fixture. Patent Document 1 discloses a vehicle light fixture comprising a housing provided on the vehicle body, an annular seal groove formed in the housing, a long, flexible seal material detachably provided in the seal groove, and a lens detachably provided in the housing. The lens has projections (seal legs) that are inserted into the seal groove while deforming the seal material. Japanese Patent Application Publication No. 11-219603 This is a perspective view showing the left front side of a vehicle and a vehicle light fixture according to the embodiment.This is an exploded perspective view of a vehicle light fixture.This is a schematic front view of part of the housing and part of the sealing material.This is a cross-sectional view of a vehicle light fixture with the lens mounted in the housing, along the arrow 4-4 in Figure 3.This is a schematic front view of a portion of the housing after the sealant has been removed from the housing's seal groove.This is a schematic front view of part of the housing and part of the new sealing material.This is a cross-sectional view along the line 7-7 in Figure 6.This is a schematic front view of a portion of the housing and a portion of the new seal material, with the lens omitted, showing the lens projection pressed into the front surface of the seal material.This is a cross-sectional view of a vehicle light fixture with the lens mounted in the housing, along the arrow 9-9 in Figure 8.This is a schematic front view of a part of the housing and a part of the new seal material, showing the lens projection of the vehicle light fixture in the comparative example pressed into the front surface of the seal material, with the lens omitted. The vehicle lighting fixture and its assembly method according to the embodiment will be described below with reference to the attached drawings. Note that the arrows UP, FR, and LH in each drawing indicate the upper side in the vehicle's vertical direction, the front side in the vehicle's longitudinal direction, and the left side in the vehicle's lateral direction, respectively. As shown in Figure 1, vehicle lights 20 are provided at two locations on the left and right sides of the front of the vehicle body 12 of the vehicle 10 to which the vehicle lights and the assembly method of the vehicle lights of this embodiment are applied (the right-hand vehicle light 20 is not shown). The left and right vehicle lights 20 are symmetrical in shape. Therefore, the left-hand vehicle light 20 shown in Figure 1 will be described first. As shown in Figure 2, the vehicle light fixture 20 includes a housing 22 that is attached to the vehicle body. The housing 22 is a hollow member with an open front. A seal groove 24 with an annular front shape is provided on the outer circumference of the front of the housing 22. The housing 22 includes an outer peripheral wall 26 with an annular front shape that defines the entire outer peripheral edge of the seal groove 24, and an inner peripheral wall 30 with an annular front shape that defines the entire inner peripheral edge of the seal groove 24. Furthermore, as shown in Figure 3, a first weak point 27 with a smaller thickness than the surrounding area is provided on the lower right side of the outer peripheral wall 26. Also, a second weak point 31 with a smaller thickness than the surrounding area is provided on the lower right side of the inner peripheral wall 30. A part of the first weak point 27 is located directly below a part of the second weak point 31. In other words, the circumferential position of the seal groove 24 in a part of the first weak point 27 coincides with the circumferential position of a part of the second weak point 31. Furthermore, an auxiliary frame 28 is provided on the lower right side of the outer peripheral wall 26. The rear (bottom) surface 28A of the auxiliary frame 28 is closed. Additionally, the lower surface of the outer peripheral wall 26 and the inner surface and rear surface 28A of the auxiliary frame 28 form an end storage space 29 with a trapezoidal front shape. The left end surface, right end surface, and bottom surface of the end storage space 29 are closed by the auxiliary frame 28. On the inner side of the inner peripheral wall 30, a space 33 is formed for providing a ramp (not shown), etc. The lens 40, a one-piece molded product of a translucent material, comprises a lens body 42 and a projection 44. The front shape of the lens body 42 is substantially the same as the front shape of the housing 22. An annular projection 44 is provided on the rear surface of the lens body 42. The rear shape (front shape) of the projection 44 is substantially the same as the front shape of the seal groove 24 of the housing 22. Figures 1, 3, and 4 show the vehicle light fixture 20 as it appeared when the vehicle 10 was manufactured. A flexible, elongated sealing material 50 is inserted i
