[0026] See Figure 1 , during the assembly process of the through - type lamp, due to factors such as the large size of the product itself, product deformation, and dimensional chain tolerance, when the lamp cover assembly 11 is directly installed with the thick - wall light guide structure 3, the docking position 4 is as Figure 1 shown. At this time, when installing, the lamp cover assembly 11 is likely to scratch the thick - wall light guide structure 3, resulting in a poor lighting effect of the final finished lamp.

[0027] See Figures 2 to 4 , a scratch - proof structure for the thick - wall light guide of a through - type headlamp in a specific embodiment of the present utility model includes a lamp cover assembly 11, a thick - wall light guide structure 3, and a decorative cover plate 2. Among them, the decorative cover plate 2 is arranged between the lamp cover assembly 11 and the thick - wall light guide structure 3. When assembling the lamp cover assembly 11 and the thick - wall light guide structure 3, the decorative cover plate 2 is arranged along the assembly direction of the lamp cover assembly 11, so that the lamp cover assembly 11 can abut against one side of the decorative cover plate 2, and the thick - wall light guide structure 3 abuts against the other side of the decorative cover plate 2. After the lamp cover assembly 11, the decorative cover plate 2, and the thick - wall light guide structure 3 are fixed, the overall fixed installation can be achieved. And during the installation process, the direct contact between the thick - wall light guide structure 3 and the lamp cover assembly 11 can be effectively restricted via the decorative cover plate 2, avoiding damage to the light guide structure 3 caused by the lamp cover assembly 11.

[0028] Specifically, in order to avoid the contact surface between the lamp cover assembly 11 and the decorative cover plate 2 being too sharp during the installation of the lamp cover assembly 11, which may cause penetration or damage to the decorative cover plate 2. Therefore, the contact surface between the lamp cover assembly 11 and the decorative cover plate 2 is set as an arc - shaped contact surface, so as to avoid damage to the decorative cover plate 2 caused by the lamp cover assembly 11 after the two are installed and abutted.

[0029] More specifically, the lamp cover assembly 11 at least includes a first component 1111, a second component 1212, and a third component 13. Among them, the first component 1111, the second component 1212, and the third component 13 are arranged in sequence along the direction away from the thick-walled light guide structure 3, and the first component 1111, the second component 1212, and the third component 13 can be fixed by means such as snap connection or bolt connection. The decorative cover plate 2 is fixed to the lamp cover assembly 11 by means of bolt connection, and the decorative cover plate 2 and the thick-walled light guide can be installed and fixed by means such as snap connection or bonding.

[0030] In addition, the thick-walled light guide structure 3, the decorative cover plate 2, and the lamp cover assembly 11 are arranged in sequence along the light emission direction. That is, the thick-walled light guide structure 3 is arranged closest to the light source direction, and then the decorative cover plate 2 and the lamp cover assembly 11 are arranged in sequence. And the thick-walled light guide structure 3 is injection-molded from transparent PC material, so as to facilitate better light penetration through the thick-walled light guide and the lamp cover assembly 11. Therefore, by arranging the decorative cover plate 2 between the lamp cover assembly 11 and the thick-walled light guide structure 3, the decorative cover plate 2 can prevent the lamp cover assembly 11 from directly contacting the thick-walled light guide structure 3 during the assembly process, thereby causing damage to the thick-walled light guide assembly, ensuring the integrity of the overall structure and the final good lighting effect, and through the setting of the decorative cover plate 2, the aesthetics of the automotive headlamp shape is also ensured.
