In application, the wire harness 5 can be threaded into the accommodating gap, thereby limiting the movement range of the wire harness 5, binding the wire harness 5 to the outer casing, and reducing the shaking of the wire harness 5.
[0040] In some embodiments, please refer to Figure 3 , Figure 6 and Figure 7 A second mounting groove 17 is provided on the outer wall of the lamp housing 1 corresponding to the mounting base 11. The insertion hole 13 is located in the middle of the second mounting groove 17. A connecting plate 32 is connected to the lower end of the inner sleeve 3. In this embodiment, the connecting plate 32 and the inner sleeve 3 are integrally formed. The outer diameter of the connecting plate 32 is larger than the outer diameter of the inner sleeve 3. In application, the inner sleeve 3 is inserted into the insertion hole 13, while the connecting plate 32 is inserted into the second mounting groove 17. The connecting plate 32 is used to restrict the movement of the inner sleeve 3 into the lamp housing 1. In this embodiment, a gripping component 321 is provided on the lower end face of the connecting plate 32. The gripping component 321 is a plate body arranged longitudinally in the middle of the connecting plate 32. During assembly, the operator can rotate and move the inner sleeve 3 by gripping the gripping component 321 to install it on the outer housing.
[0041] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 9Multiple protrusions 33 are provided on the outer side wall of the inner sleeve 3, and a clearance groove 16 is provided on the side wall of the insertion hole 13 for the protrusions 33 to pass through. During assembly, the inner sleeve 3 is first inserted into the insertion hole 13 from the outside to the inside, and then the inner sleeve 3 is rotated so that the protrusions 33 and the clearance groove 16 are intersected. In this way, the protrusions 33 can be stuck on the bottom surface of the first mounting groove 12, restricting the inner sleeve 3 from moving to the outside of the lamp housing 1.
[0042] Furthermore, an elastic pad 6 is provided between the bottom of the connecting plate 32 and the second mounting groove 17. Specifically, an annular groove is provided on the upper surface of the connecting plate 32. The elastic pad 6 can be a rubber ring inserted into the annular groove. After the inner sleeve 3 is installed, the elastic pad 6 is in a compressed state. The elastic force of the elastic pad 6 drives the inner sleeve 3 to move outward, so that the protrusion 33 abuts against the bottom surface of the first mounting groove 12, so that the inner sleeve 3 and the outer sleeve are relatively fixed.
[0043] In this embodiment, a limiting part for restricting the rotation of the protrusion 33 is provided on the bottom surface of the first mounting groove 12. The limiting part includes a first protrusion 18 and a second protrusion 19. The first protrusion 18 is disposed on one side of the clearance groove 16, and the second protrusion 19 is disposed on the side of the first protrusion 18 away from the clearance groove 16. A limiting gap is provided between the first protrusion 18 and the second protrusion 19. In application, the protrusion 33 is stuck in the limiting gap, and the first protrusion 18 and the second protrusion 19 are used to restrict the rotation of the protrusion 33.
[0044] In this embodiment, the distance between the protrusion 33 and the connecting plate 32 is slightly greater than the side wall thickness of the outer shell between the first mounting groove 12 and the second mounting groove 17. The elastic pad 6 installed in the annular groove protrudes from the upper surface of the connecting plate 32. The first protrusion 18 has a guide surface 181 that is inclined downwards towards the avoidance groove 16 at one end. In application, the inner sleeve 3 is rotated towards the first protrusion 18, so that the protrusion 33 moves upward along the guide surface 181 of the first protrusion 18, passes the first protrusion 18, and enters the limiting gap. During the process, the change in the distance between the connecting plate 32 and the second mounting seat 11 can be compensated by the deformation of the elastic pad 6.
[0045] This utility model also provides a vehicle lamp that uses the above-mentioned automotive lamp bulb 4 fixing structure.
[0046] Compared with the prior art, the vehicle lamp provided by this utility model uses the above-mentioned fixing structure of the car lamp bulb 4, so that the wiring harness 5 is housed inside the lamp housing 1, thereby avoiding damage caused by friction between the wiring harness 5 and external parts, and improving the service life of the wiring harness 5. In addition, after the wiring harness 5 is housed inside the lamp housing 1, the appearance of the vehicle lamp is improved.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
