DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1-Figure 6 As shown, a headlight height adjustment structure comprises a position light 1, a headlight 2, a mounting bracket 3 and an adjusting bolt 4, the upper end of the headlight 2 is provided with a rotating pin 211, the front end of the mounting bracket 3 is buckled on the back of the position light 1 and is detachably connected to the position light 1 and covers the headlight 2 therein, and a pin hole 11 is formed between the position light 1 and the mounting bracket 3 for the rotating pin 211 to be inserted and rotatably matched therewith, the position light 1 is annular and has a light-through hole 12 in the middle for the light of the headlight 2 to pass through, the adjusting bolt 4 is rotatably penetrated on the mounting bracket 3 and the end thereof is threadedly connected and matched with the lower end of the headlight 2.

[0023] Use the position lamp 1 as the mounting base. During installation, first insert the rotating pin 211 on the upper end of the headlight 2 into the position corresponding to the pin hole 11 on the position lamp 1. Then press the front end of the mounting bracket 3 onto the back of the position lamp 1 and fix it. Finally, install it on the faucet cover together with the decorative connecting plate. The structure of the mounting bracket 3 is integrated into the overall lighting structure formed by the position lamp 1 and the headlight 2. The rotating pin 211 structure is used as a part of the structure of the headlight 2, which simplifies the number of parts, simplifies the processing technology, and effectively improves the efficiency of assembly.

[0024] Principle of headlight height adjustment: rotate the adjusting bolt 4 with the rotating pin 211 at the upper end of the headlight 2 as the rotation center, and the end of the adjusting bolt 4 cooperates with the thread at the lower end of the headlight 2 to realize the vertical flipping of the headlight 2, thereby achieving the purpose of adjusting the illumination height of the headlight 2.

[0025] like Figure 4 , Figure 5 As shown, the headlight 2 includes a lamp housing 21, a lamp shade 22 and a fixing ring 23. One side of the lamp housing 21 has a mounting opening 212, and an annular sealing groove 213 is formed along the outer periphery of the mounting opening 212. The bottom of the lamp shade 22 is circumferentially expanded, and the bottom of the lamp shade 22 is engaged with the sealing groove 213 and pressed against the sealing groove 213 to form a sealing structure to play a role in waterproofing and dustproofing the interior of the headlight. The lamp shade 22 is snap-connected with the lamp housing 21, and the fixing ring 23 is sleeved on the outside of the lamp shade 22 and buckled on the bottom of the lamp shade 22 and snap-connected with the lamp housing 21. The fixing ring 23 further improves the strength and tightness of the connection between the lamp shade 22 and the lamp housing 21.

[0026] The rotating pin 211 is located at the upper end of the lamp housing 21 and is integrally injection molded with the lamp housing 21. The interior of the lamp housing 21 is used to install the light-emitting components. The mass of the headlight 2 is mainly concentrated on the lamp housing 21. The rotating pin 211 is located at the upper end of the lamp housing 21 and is integrally injection molded with the lamp housing 21, which not only makes the height adjustment of the headlight 2 more labor-saving, but also reduces the number of matching parts and simplifies the processing technology.

[0027] like Figure 1 , Figure 6 After the headlight 2 and the position light 1 are installed together, the lampshade 22 is inserted into the light hole 12. This is used to prevent the position light 1 and the headlight 2 from occupying too much space in the vehicle, and to make the overall structure of the position light 1 and the headlight 2 more compact, thereby increasing the adjustment range of the headlight 2.

[0028] Furthermore, a main heat dissipation port 31 is provided at the rear end of the mounting bracket 3, and auxiliary heat dissipation ports 32 are symmetrically provided on both sides of the mounting bracket 3. The headlight 2 generally adopts an LED lamp, and the main heat dissipation port 31 and the auxiliary heat dissipation port 32 mainly play the role of heat dissipation of the headlight 2, and while ensuring the structural strength of the mounting bracket 3, unnecessary supporting structures are eliminated, thereby effectively reducing the mass of the mounting bracket 3.

[0029] Furthermore, if Figure 3 As shown, the back of the position lamp 1 is provided with a plurality of positioning bosses 13, and the front end of the mounting bracket 3 is provided with a plurality of limiting grooves 33 corresponding to the positioning bosses 13 for insertion. The positioning bosses 13 facilitate accurate installation of the mounting bracket 3 and the position lamp 1. After the mounting bracket 3 is installed on the faucet cover, the limiting grooves 33 limit the positioning bosses 13 to prevent the mounting bracket 3 and the position lamp 1 from being displaced during use.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
