Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a vehicle lamp with high sealing performance. Background Art

[0002] Halogen bulbs are simply called halogen bulbs or halogen lamps, also known as tungsten halogen bulbs and quartz bulbs. They are a variant of incandescent lamps. The principle is to inject halogen gas such as iodine or bromine into the bulb. Under high temperature, the sublimated tungsten filament reacts chemically with the halogen. The cooled tungsten will re-solidify on the tungsten filament, forming a balanced cycle, which prevents the tungsten filament from breaking prematurely. Therefore, halogen bulbs are longer-lived than incandescent lamps. The biggest difference between halogen bulbs and other incandescent lamps is that the glass shell of the halogen lamp is filled with some halogen element gas (usually iodine or bromine).

[0003] A Chinese patent with announcement number CN209658135U discloses a fixing structure for an automotive halogen lamp. It is equipped with a movable cavity, a partition, two movable springs and two latches inside a connecting base, so that the latches can move left and right inside the movable cavity through the elastic force of the movable springs. Sliders are provided at the top and bottom of the latches, and a slide groove is provided inside the connecting base. The slide groove is movably connected to the slider, so that the latches can slide left and right inside the slide groove through the slider, making the movement of the latch more stable. At the same time, the movement of the latches is limited to prevent them from falling off.

[0004] The above solution uses the elastic force of a movable spring to insert the slider into the slot to limit the connection base. Although this facilitates the disassembly and assembly of the connection base and the mounting base, the mounting base has a large cavity, and a gap still exists between the connection base and the mounting base after installation. External dust and debris can enter, affecting the electrical connection of the connection base and thus shortening the service life of the headlight. To address this problem, we provide a headlight with high sealing performance to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-3 As shown, the utility model provides a technical solution: a vehicle lamp with high sealing performance, comprising a plug-in 1, a bulb 6 and a limiting component.

[0027] A connecting plate 2 is fixedly connected to the plug-in 1, a connecting seat 4 is fixedly connected to the connecting plate 2, a first sealing plate 3 is fixedly connected to the connecting plate 2, and the connecting seat 4 is located inside the first sealing plate 3. When the plug-in 1 is installed, the first sealing plate 3 will be released from the installation surface, thereby improving the sealing of the headlight after installation. An electrode seat 11 is embedded in the connecting seat 4, and a through hole 5 is opened on the upper surface of the connecting seat 4.

[0028] A lamp holder 7 is installed on the bulb 6. The bottom end of the lamp holder 7 passes through the through hole 5 and contacts the electrode holder 11. There is a metal sheet at the bottom end of the lamp holder 7. The metal sheet and the electrode holder 11 are released to complete the electrical connection between the plug-in 1 and the filament in the bulb 6. A second sealing plate 8 is fixedly connected to the lamp holder 7, and the second sealing plate 8 abuts against the upper surface of the connecting seat 4. A positioning pin 10 is fixedly connected to the connecting seat 4. A positioning hole 9 is opened on the second sealing plate 8, and the second sealing plate 8 is inserted into the positioning pin 10 through the positioning hole 9.

[0029] When the bulb 6 is installed, the lamp holder 7 extends through the through hole 5 into the interior of the connecting base 4, and the second sealing plate 8 covers the connecting base 4, thereby blocking the connection between the lamp holder 7 and the connecting base 4, thereby preventing external debris from entering the connecting base 4.

[0030] The limiting component includes a locking piece installed on the lamp holder 7 and a snap-fit ​​piece installed in the connecting seat 4. The lamp holder 7 is limited by the locking piece being longitudinally inserted into the snap-fit ​​piece, and the locking piece is released from the limit with the snap-fit ​​piece by rotating in the connecting seat 4.

[0031] The locking member includes a control ring 14 fixedly connected to the lamp holder 7, and a movable groove 15 in a circumferential array is provided on the control ring 14. A connecting rod 16 is slidably connected in the movable groove 15. One end of the connecting rod 16 is fixedly connected to a hemispherical block 17, and the hemispherical block 17 is located outside the control ring 14.
