[0024] See Figure 1 and Figure 2 The preferred embodiment of the present invention provides a headlight lighting assembly, including a first connecting member 1, a second connecting member 2, an elastic positioning member 3, an elastic lifting assembly 24 and a lighting lamp 5. The lighting lamp 5 is installed on the first connecting member 1. The second connecting member 2 is provided with a fixing member 6. The fixing member 6 is used to fix the second connecting member 2 to the vehicle. The elastic lifting assembly 24 is used to adjust the connection angle between the first connecting member 1 and the second connecting member 2, so as to adjust the lighting angle of the lighting lamp 5. The elastic lifting assembly 24 is used to limit the rotation range of the first connecting member 1 to prevent the first connecting member 1 and the second connecting member 2 from separating due to excessive torque.

[0025] See Figure 3 and Figure 3Specifically, a clamping protrusion 11 is provided on the first connecting member 1, a cross rotating portion 12 is provided on the surface of the first connecting member 1 away from the clamping protrusion 11, a support ear 111 is provided on the side of the clamping protrusion 11, and a clamping groove 21 is provided on the second connecting member 2. The clamping groove 21 is used to limit the clamping protrusion 11, and the side of the clamping groove 21 is extended with a support ear groove 22 and a limiting groove 23. The support ear groove 22 is used to limit the support ear 111, and the support ear groove 22 and the limiting groove 23 are connected. A limiting plate 231 is provided on the upper edge of the limiting groove 23, and the limiting plate 231 is used to abut against the support ear 111. During assembly, first place the snap-fit protrusion 11 and the ear 111 into the snap-fit groove 21 and the ear groove 22 respectively, and align the positioning protrusion 311 with the positioning groove 112. Then, hold the cross-rotating part 12 and rotate the first connecting member 1 to rotate the ear 111 into the limiting groove 23, so that the ear 111 abuts against the limiting plate 231, thereby completing the assembly of the first connecting member 1 and the second connecting member 2.

[0026] The end face of the clamping protrusion 11 is provided with a positioning groove 112 and a plurality of tooth-connecting grooves 113, and the plurality of tooth-connecting grooves 113 surround the positioning groove 112. The bottom of the clamping groove 21 is provided with a connecting groove 211, and the elastic positioning member 3 is located in the connecting groove 211. The elastic positioning member 3 includes a positioning body 31 and an elastic member 32. The elastic member 32 is located below the positioning body 31. A positioning protrusion 311 and a plurality of tooth-connecting protrusions 312 are provided on the positioning body 31. The plurality of tooth-connecting protrusions 312 surround the positioning protrusion 311. The positioning protrusion 311 is used to connect with the positioning groove 112, and the tooth-connecting protrusion 312 is used to connect with the tooth-connecting groove 113. After the first connecting member 1 and the second connecting member 2 are assembled, the positioning protrusion 311 is connected to the positioning groove 112, and the toothed protrusion 312 is connected to the toothed groove 113. Since the elastic member 32 is located below the positioning body 31, by pressing down and rotating the lighting lamp 5, the first connecting member 1 is driven to press down and rotate, so that the positioning body 31 moves downward, and the toothed groove 113 is misaligned with the toothed protrusion 312, and the positioning protrusion 311 rotates in the positioning groove 112. When rotated to a certain angle, the toothed groove 113 is connected to the toothed protrusion 312 again. At this time, the first connecting member 1 is connected to the second connecting member 2 at another angle, so as to adjust the lighting angle of the lighting lamp 5 installed on the first connecting member 1.

[0027] See Figure 4 and Figure 5Furthermore, a limiting tube 212 is provided in the connecting groove 211. The elastic member 32 includes a first coil spring 321. The first coil spring 321 is located between the outer wall of the limiting tube 212 and the inner wall of the connecting groove 211. One axial end of the first coil spring 321 abuts against the positioning body 31. The outer wall of the positioning body 31 is provided with an annular limiting portion 313. One end of the positioning body 31 is located in the limiting tube 212. The limiting portion 313 is used to abut against the limiting tube 212. When the first connecting member 1 presses the positioning body 31 downward, the limiting portion 313 abuts against the limiting tube 212 to limit the descending height of the positioning body 31. The first coil spring 321 is compressed by the positioning body 31. When the pressure is reduced, the first coil spring 321 automatically pushes the positioning body 31 upward, so that the toothed protrusion 312 and the toothed groove 113 are reconnected.

[0028] Furthermore, a connecting column 213 is provided in the limiting tube 212, and a receiving groove 314 is provided in the positioning body 31. The connecting column 213 is located in the receiving groove 314. During the lifting and lowering process of the positioning body 31, the connecting column 213 is always located in the receiving groove 314 to prevent the positioning body 31 from shifting.

[0029] See Figure 2 In this embodiment, two lugs 111, two lug slots 22, and two limiting slots 23 are each provided. The two lug slots 22 are used to limit the two lugs 111, respectively. Limiting plates 231 are provided on the upper edges of the two limiting slots 23. When the first connector 1 and the second connector 2 are assembled, the two lugs 111 abut against the two limiting plates 231, respectively. This creates two sets of limiting structures between the first connector 1 and the second connector 2, further preventing separation and enhancing the secure connection between the two connectors.

[0030] See Figure 3 In this embodiment, notches 114 are provided on both outer sides of the two ears 111 to prevent the outer sides of the ears 111 from scraping against the inner wall of the ear slot 22 , thereby facilitating the assembly of the ears 111 and the ear slot 22 .

[0031] In other embodiments, more than two ears 111, ear slots 22, and limit slots 23 may be provided, so that more than two groups of limit structures are provided between the first connecting member 1 and the second connecting member 2 to ensure the connection strength of the first connecting member 1 and the second connecting member 2.

[0032] See Figure 2 The edges of the two limiting plates 231 near the support ear slot 22 are both chamfered to facilitate the transfer of the support ear 111 from the support ear slot 22 into the limiting slot 23, further facilitating the assembly of the first connecting member 1 and the second connecting member 2.

[0033] See Figure 1The fixing member 6 includes a rack 61 and a clamping portion 62. The clamping portion 62 is provided with a clamping hole 621 for clamping with the rack 61. By inserting the rack 61 into the clamping hole 621 and clamping the clamping hole 621 with the rack 61 at different positions, the fixing member 6 can be installed on components of different sizes.

[0034] See Figure 3 In this embodiment, two bolt holes 13 are provided on the first connecting member 1, and the lighting lamp 5 is connected to the bolt holes 13 respectively through two bolts, so that the lighting lamp 5 is fixedly installed on the first connecting member 1, and the two are firmly connected.

[0035] In other embodiments, more than two bolt holes 13 may be provided on the first connecting member 1 , and the illuminating lamp 5 may be connected to the bolt holes 13 via two or more bolts, thereby further ensuring that the illuminating lamp 5 is fixedly connected to the first connecting member 1 .

[0036] See Figure 2 and Figure 4 The elastic lifting assembly 24 is arranged in the ear groove 22, and the elastic lifting assembly 24 is used to move in the vertical direction to limit the rotation of the ear 111. When assembling the first connecting member 1 and the second connecting member 2, the first connecting member 1 is pressed downward so that the ear 111 presses the elastic lifting assembly 24 downward, and then the first connecting member 1 is rotated relative to the second connecting member 2, and the ear 111 is turned into the limiting groove 23 so that the ear 111 abuts against the limiting plate 231. At the same time, since the ear 111 is separated from the elastic lifting assembly 24, the elastic lifting assembly 24 moves upward. When the torque is too large, the first connecting member 1 rotates relative to the second connecting member 2. When the ear 111 abuts against the elastic lifting assembly 24, the rotation stops. At this time, the first connecting member 1 and the second connecting member 2 cannot be separated, thereby preventing the first connecting member 1 and the second connecting member 2 from separating when the torque is too large.

[0037] The elastic lifting assembly 24 includes a limit pin 241 and a second coil spring 242. A lifting slot 25 is provided on the second connecting member 2, which is connected to the support ear slot 22. The limit pin 241 and the second coil spring 242 are both vertically disposed within the lifting slot 25, with the second coil spring 242 located below the limit pin 241. When pressed by the support ear 111, the limit pin 241 compresses the first coil spring 242 downward. After the support ear 111 separates from the limit pin 241, the first coil spring 242 uses its elasticity to push the limit pin 241 upward, causing one end of the limit pin 241 to protrude from the lifting slot 25. This restricts the first connecting member 1 to a small rotation range, thereby preventing the first connecting member 1 from separating from the second connecting member 2.

[0038] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments.
