The lamp housing 101 is used to mount the vehicle lamp and has a mounting hole 11. One end of the wiring inlet 1 extends into the lamp housing 101 through the mounting hole 11. The wiring outlet 2 is disposed at the other end of the wiring inlet 1. A glue injection cavity 3 is formed inside the wiring outlet 2 and the wiring inlet 1, and the glue injection cavity 3 passes through both ends of the wiring inlet 1. Multiple wiring outlet holes 4 are opened on the first side 81 of the wiring outlet 2. The wire-passing plate 5 is disposed in the glue injection cavity 3 and is perpendicularly connected to a second side 82 that is parallel to the first side 81. The wire-passing plate 5 has multiple wire-passing holes 51. Multiple vehicle lamp wiring harnesses pass through the wire-passing holes 51 from outside the lamp housing 101, bend at 90 degrees in the glue injection cavity 3, and exit through the wiring outlet holes 4. In this embodiment, the wire outlet 2, the wire inlet 1, the glue injection cavity 3, the wire outlet hole 4, and the wire threading plate 5 are integrally formed. By positioning multiple wire outlet holes 4 and multiple wire threading holes 51, the vehicle light wiring harness can pass through the wire threading hole 51, bend at a 90-degree angle in the glue injection cavity 3, and then exit through the wire outlet hole 4. This can meet the bending and sealing requirements of multiple vehicle light wiring harnesses while reducing space.

[0038] Specifically, the cable inlet 1 includes a cylindrical first outer frame 6 and an annular plate 7. The annular plate 7 is arranged around one end of the first outer frame 6, and the other end of the first outer frame 6 extends into the lamp housing 101. In this embodiment, the first outer frame 6 is cylindrical.

[0039] Specifically, the cable outlet 2 includes a multifaceted cylindrical second outer frame 8 and a cover plate 9; one end of the second outer frame 8 is connected to one end of the first outer frame 6; the cover plate 9 is movably disposed at the other end of the second outer frame 8. In this embodiment, the second outer frame 8 is a multifaceted cylinder with a set of mutually parallel surfaces, and the mutually parallel first side surface 81 and second side surface 82 on the cable outlet 2 are a set of mutually parallel surfaces of the second outer frame 8. In this embodiment, the second outer frame 8 is a rounded rectangular cylinder.

[0040] In this embodiment, one end of the second outer frame 8 is connected to one end of the first outer frame 6, the center lines of the first outer frame 6 and the second outer frame 8 coincide, and an injection cavity 3 is formed inside the first outer frame 6 and the second outer frame 8, with the injection cavity 3 connected to both ends of the first outer frame 6.

[0041] In this embodiment, multiple wire outlet holes 4 are formed on the first side 81 of the wire outlet base 2, and the wire through hole plate 5 is vertically connected to the second side 82 near the end of the first outer frame 6. In this way, the headlight wiring harness has sufficient bending space within the first outer frame 6 after passing through the wire through hole plate 5.

[0042] In this embodiment, the cover plate 9 is a bendable plug, and one side of the cover plate 9 is movably connected to one end of the second side 82. An annular support frame 20 is arranged around one end of the first outer frame 8 near the cover plate 9. A locking block 21 is provided at the upper end of the other two sides connecting the first side 81 and the second side 82 away from the second side. The cover plate 9 presses the locking block 20 to deform and then enters between the locking block 21 and the annular support frame 20, thereby achieving the fastening of the cover plate 9.

[0043] In this embodiment, two first stiffening plates 18 are symmetrically arranged within the first frame. The same end of each first stiffening plate 18 is flush with one end of the first frame, and both sides of each first stiffening plate 18 extend to connect with the inner wall of the first frame. This improves the deformation resistance of the first frame, thereby enhancing sealing stability. In this application, the other ends of the two first stiffening plates 18 abut against the first side surface 81 and the second side surface 82, respectively.

[0044] In this embodiment, a second stiffening plate 19 is provided on the outside of the second outer frame 8. One end of the second stiffening plate 19 is connected to the second outer frame 8, and the other end is connected to the annular plate 7. Four second stiffening plates 19 are arranged around the second outer frame 8, which can improve the deformation resistance of the second outer frame 8 and thus improve the sealing stability.

[0045] In this embodiment, the outer contour of the first outer frame 6 is larger than the outer contour of the second outer frame 8, the outer ring of the annular plate 7 extends outward relative to the first outer frame 6 to form a mounting portion 7171, and the inner ring of the annular plate 7 abuts against the outer contour of the second outer frame 8.

[0046] Specifically, it also includes a sealing ring 10, which is sleeved on the first outer frame 6, with one side of the sealing ring 10 abutting against the annular plate 7. In this embodiment, when the sealing wire outlet structure is installed on the vehicle lamp housing 101, the other side of the sealing ring 10 elastically abuts against the vehicle lamp housing 101, thereby improving the sealing performance of the sealing wire outlet structure installed on the vehicle lamp housing 101.

[0048] In this embodiment, there are four mounting blocks 13, which are of different shapes and are arranged around the other end of the first outer frame 6. Four mounting grooves 12 are arranged around the inner edge of the mounting hole 11. The shape of the four mounting grooves 12 is consistent with the outer contour of the four mounting blocks 13. The four mounting grooves 12 are slightly larger than the outer contour of the four mounting blocks 13, so that the four mounting blocks 13 can pass through the four mounting grooves 12 to the other side of the mounting hole 11. The first fixing block 14 and the second fixing block 15 are arranged around the side of the other side of the mounting hole 11, and one of the mounting blocks 13 is rotatably engaged between the first fixing block 14 and the second fixing block 15.

[0049] In this embodiment, an annular cavity 17 is formed on the lamp housing 101. The mounting hole 11 is located at the center of the bottom of the annular cavity 17. The first frame and the mounting block 13 pass through the mounting hole 11 and the mounting groove 12 through the annular cavity 17 to reach the other side of the lamp housing 101. The sealing ring 10 elastically abuts against the bottom of the annular cavity 17.

[0050] Specifically, it also includes a knob block 16, which is disposed outside the cable outlet 2. In this embodiment, the two knob blocks 16 are respectively disposed outside the other two sides connecting the first side 81 and the second side 82. In use, the knob block 16 is driven to rotate, thereby causing the mounting block 13 to rotate between the first fixing block 14 and the second fixing block 15, which facilitates installation.

[0051] How to use the sealed cable outlet structure of this application:

[0052] 1. Open the cover plate 9, pass multiple headlight wire harnesses through different wire holes 51 of the wire hole plate 5, then make a 90-degree bend in the glue injection cavity 3, and then exit through different wire outlet holes 4 to the outside of the sealed wire outlet structure, and then fasten the cover plate 9.

[0053] 2. Align the mounting block 13 with the mounting groove 12, pass the first frame and mounting block 13 through the mounting hole 11 and mounting groove 12 through the other side of the lamp housing 101, so that the sealing ring 10 elastically abuts against the lamp housing 101, and then drive the knob block 16 to rotate, causing the mounting block 13 to rotate and engage between the first fixing block 14 and the second fixing block 15, so as to install the sealed wire outlet structure on the lamp housing 101.

[0054] 3. Then, inject glue into the glue injection cavity 3 to seal it, thereby sealing the vehicle light wiring harness.
