[0021] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

[0022] refer to Figure 1 、 Figure 2 、 Figure 3 A thin-walled automobile lamp includes a shell 1, a translucent lampshade 4, and a light-emitting component 5. The translucent lampshade 4 is covered on the reflective cavity 101. The edge of the translucent lampshade 4 is detachably connected to the shell 1. Preferably, the connection between the edge of the translucent lampshade 4 and the shell 1 can be a bolt connection or a snap connection.

[0023] A reflective cavity 101 is defined in the side wall of the housing 1. A mounting hole 2 is formed through the inner wall of the reflective cavity 101. The mounting hole 2 comprises a coaxially arranged connecting hole 21 and a sliding hole 22. The connecting hole 21 is a threaded hole. The opening of the sliding hole 22 extends through the inner wall of the reflective cavity 101. The connecting hole 21 extends to the outer wall of the housing 1. A protective cover 3 is movably sleeved on the inner wall of the sliding hole 22. The outer wall of the protective cover 3 covers the inner wall of the connecting hole 21, thereby protecting the inner wall of the connecting hole 21. The outer wall of the protective cover 3 covering the inner wall of the connecting hole 21 effectively prevents dust and other foreign matter from entering the threads within the connecting hole 21, ensuring smooth installation of the first light source 51 and improving the service life and installation safety of the vehicle lamp.

[0024] The light-emitting assembly 5 includes three first light sources 51 and several second light sources 52. Each first light source 51 is detachably connected to the outer shell 1. The light-emitting end of each first light source 51 is directed toward the translucent lampshade 4. The bottom inner wall of the reflective cavity 101 is formed with several concave cavities 102. Each second light source 52 is positioned and installed on each concave cavity 102. The light-emitting end of each second light source 52 is directed toward the translucent lampshade 4.

[0025] The first light source 51 is provided with a mounting sleeve 6, which is socketed with the protective sleeve 3. The outer wall of the mounting sleeve 6 is provided with a connecting ring 601. During the installation of the first light source 51 in the outer shell 1, the mounting sleeve 6 is inserted into the protective sleeve 3, so that the end face of the connecting ring 601 abuts against the side wall of the protective sleeve 3. The inner wall of the side of the protective sleeve 3 extending into the reflection cavity 101 is provided with a retaining ring 301. The end of the mounting sleeve 6 inserted into the protective sleeve 3 abuts against the opposite side of the retaining ring 301. The protective sleeve 3 will slide with the movement of the first light source 51, thereby exposing the inner wall of the connecting hole 21, so that the connecting ring 601 is threadedly connected to the connecting hole 21.

[0026] Two guide rods 302 are symmetrically provided on the side outer wall of the protective sleeve 3 extending into the reflective cavity 101. A guide hole 9 is formed through the inner wall of the reflective cavity 101, through which the guide rods 302 are slidably connected. A limit slot 10 is defined in the inner wall of the guide hole 9, and the opening of the limit slot 10 extends through the outer wall of the housing 1. A limit member 7 is detachably connected to the guide rod 302, which is slidably connected to the limit slot 10. This ensures that the protective sleeve 3 can stably translate and slide along its axial direction within the sliding hole 22, preventing the protective sleeve 3 from rotating within the sliding hole 22 due to external forces. A protective cover 602 is provided on the outer wall of the mounting sleeve 6. When the connecting ring 601 is threadedly connected to the connecting hole 21, the protective cover 602 contacts and engages with the opposite side of the housing 1, covering the opening of the limit slot 10.

[0027] A magnetic block 8 is provided on the inner wall of the limiting groove 10. The limiting member 7 is made of magnetic material. The magnetic force between the limiting member 7 and the magnetic block 8 is a repulsive force, which makes the protective cover 3 tend to extend outward. When the first light source 51 is disassembled from the outer shell 1, under the action of the magnetic force between the limiting member 7 and the magnetic block 8, the protective cover 3 is reset and translated so that the outer wall of the protective cover 3 covers the inner wall of the connecting hole 21.

[0028] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
