[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A well-sealed automotive combination lamp includes a mounting plate 1, a waterproof mounting cover 2, and a protective lamp cover 3. The mounting plate 1 is made of high-strength ABS engineering plastic and is used for precise fixing to the vehicle body. The waterproof mounting cover 2 is fixedly connected to the top of the mounting plate 1, providing a sealed mounting cavity for the combination lamp assembly. The top of the waterproof mounting cover 2 has an inner insertion groove 4 that matches the protective lamp cover 3, enabling precise insertion of the inner side of the protective lamp cover 3. Two sets of locking mechanisms 5 are symmetrically fixedly installed on the outer side of the waterproof mounting cover 2 for fixing the protective lamp cover 3, ensuring connection stability and force balance. The outer surface of the protective lamp cover 3 has a wraparound design. The unit is integrally formed with an outer water-retaining cover 6 and a protective lamp cover 3 made of high-transmittance PC material. The surface is treated with an anti-scratch and anti-fog coating, which has excellent light transmittance, wear resistance and anti-fog effect. The outer water-retaining cover 6 and the protective lamp cover 3 are integrally formed to form a water-retaining eave structure, which can directly prevent rainwater from flowing along the surface of the lamp cover to the insertion gap. The top of the waterproof mounting cover 2 is provided with an external insertion groove 7 that is compatible with the outer water-retaining cover 6 to achieve an external sealed insertion. The top of the mounting plate 1 and the inner side of the waterproof mounting cover 2 are provided with a combined lamp assembly, which integrates multiple functions such as turn signals, brake lights and position lights. It is fixedly connected to the mounting plate 1 through a waterproof joint.

[0022] Both the inner insertion slot 4 and the outer insertion slot 7 are equipped with elastic sealing gaskets. The elastic sealing gaskets are made of aging-resistant, highly elastic silicone material, and the surface has annular anti-slip protrusions. When the protective lamp cover 3 and the outer water shield 6 are inserted into the corresponding insertion slots, the sealing gaskets are tightly attached to the slot wall and the outer wall of the lamp cover under the pressure, forming a double inner seal, which effectively prevents rainwater and dust from seeping in. The elastic sealing gaskets are fixed to the inner wall of the insertion slots with environmentally friendly adhesives to prevent them from falling off after long-term use and to facilitate later maintenance and replacement.

[0023] The locking mechanism 5 includes a rectangular shell 51, which is fixedly connected to the outer surface of the waterproof mounting cover 2 by welding. Bearing seats 52 are symmetrically installed on both sides of the inner wall of the rectangular shell 51. The bearing seats 52 are deep groove ball bearings, providing stable support for the screw and reducing rotational resistance. A screw 53 is installed in the bearing within the bearing seat 52. A driven bevel gear 54 is fixedly connected to the end of the screw 53 away from the bearing seat 52. A transverse sliding seat 55 is threaded axially onto the screw 53. The inner wall of the transverse sliding seat 55 has an internal thread adapted to the screw, and its outer wall fits against the inner wall of the rectangular shell 51. Locking rods 56 are fixedly connected to the opposite sides of the two transverse sliding seats 55. Made of stainless steel with rust-proof surface treatment, it has high strength and is not easily deformed. Guide rods 57 are fixedly connected between the two sides of the inner wall of the rectangular shell 51. The guide rods 57 are parallel to the screw 53. The transverse sliding seat 55 is slidably connected to the surface of the guide rods 57 along the axial direction to ensure smooth movement of the transverse sliding seat and avoid deviation and jamming. A rotating handle 58 is also rotatably connected to the rectangular shell 51. The outer surface of the rotating handle 58 is provided with anti-slip texture for easy gripping and force application. One end of the rotating handle 58 passes through the interior of the rectangular shell 51 and is fixedly connected to the driving bevel gear 59 that matches the driven bevel gear 54. Through the meshing transmission of the bevel gears, the conversion of rotary motion to linear motion is realized, which is labor-saving and precise in transmission.

[0024] A threaded sleeve 510 is welded to the top of the rectangular shell 51 via a bracket. The threaded sleeve 510 is perpendicular to the axis of the rotating handle 58. A locking bolt 511 is connected to the internal thread of the threaded sleeve 510. One end of the locking bolt 511 passes through the insertion hole on the outside of the rotating handle 58 and is inserted and fixed thereto. This locks the position of the rotating handle and prevents the locking mechanism from loosening due to vibrations during vehicle operation, thus achieving secondary anti-loosening. A limiting ring 512 is fixedly connected to the surface of the rotating handle 58. The limiting ring 512 is an annular protrusion structure. The limiting ring 512 is movably connected to the rectangular shell 51, limiting the axial displacement of the rotating handle and ensuring the meshing stability of the driving bevel gear 59 and the driven bevel gear 54, thus preventing transmission failure.

[0025] The waterproof mounting cover 2 has a first passage 8 on its outer side that is compatible with the horizontal sliding seat 55. The protective lamp cover 3 has a second passage 9 that communicates with the first passage 8. The second passage 9 has positioning locking holes 10 on both sides that are compatible with the locking rod 56. When locking, the horizontal sliding seat 55 moves laterally and the locking rod 56 is inserted into the positioning locking hole 11, so as to achieve a firm lock between the protective lamp cover 3 and the waterproof mounting cover 2. The positioning locking hole 11 is provided with an elastic rubber ring to enhance the fit and sealing between the locking rod 56 and the hole wall, and at the same time play a buffering and vibration damping role to further prevent vibration and loosening.

[0026] The mounting plate 1 has several through positioning holes 12, which are evenly distributed along the edge of the mounting plate. The mounting plate is fixed to the vehicle body by bolts. Anti-slip washers are provided in the positioning holes 12 to prevent the bolts from loosening.

[0027] In use, the combined lighting assembly is fixedly installed on the top of the mounting plate 1 through the waterproof connector, ensuring that the wiring is sealed. The protective lamp cover 3 is aligned with the inner insertion slot 4 of the waterproof mounting cover 2, and the outer water-blocking cover 6 is aligned with the outer insertion slot 7. It is slowly inserted to the bottom. The rotating handle 58 is held and rotated. Through the meshing of the active bevel gear 59 and the driven bevel gear 54, the screw 53 is driven to rotate. The screw 53 drives the two transverse sliding seats 55 to move in the opposite direction along the guide rod 57. The stop rod 56 is inserted into the positioning locking hole 11 to achieve a firm lock between the protective lamp cover 3 and the waterproof mounting cover 2. The locking bolt 511 in the screw sleeve 510 is tightened so that it is inserted into the insertion hole of the rotating handle 58 to complete the secondary anti-loosening.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
