Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an automotive lighting fixture with good waterproof performance. Background Technology

[0002] Automotive headlights are a complete optoelectronic equipment system installed on automobiles to achieve functions such as lighting, signal indication, and decoration.

[0003] Most mainstream automotive lights use pre-compressed rubber sealing rings, relying on the fixed compression generated when the lamp cover and lamp housing are clamped together to achieve a seal. Rubber materials harden, crack, and permanently deform over time, their elastic recovery decreases, and the sealing performance deteriorates linearly, making it easy for external moisture to penetrate along the joint between the lamp cover and lamp housing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vehicle light with good waterproof performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waterproof vehicle light includes a lamp housing, inside which a lighting component is provided, and a lamp cover is sealed and snapped onto the lamp housing. An extension ring is provided on the side of the lamp cover adjacent to the mounting surface. Three sets of grooves are equally spaced on the outer wall of the extension ring. An airbag for sealing is fitted outside the grooves. An airflow channel for ventilation is provided inside the extension ring between two adjacent grooves. An air inlet is provided on the side of the lampshade away from the mounting surface at the corresponding airflow channel. A transition channel is provided in the extended ring between the air inlet and the adjacent groove. A sealing plug is screwed onto the lampshade at the air inlet.

[0006] In addition, a preferred structure is that the sealing plug is provided with a threaded portion, and a groove is provided on the end face of the sealing plug, with a handle provided in the groove.

[0007] Furthermore, in a preferred configuration, a sealing cavity is provided on the side of the lampshade away from the mounting surface at the sealing plug, and a threaded groove adapted to the threaded portion is provided inside the sealing cavity.

[0008] Furthermore, a preferred configuration is that, after the sealing plug is threadedly connected to the sealing cavity, the end face of the sealing plug is flush with the end face of the lampshade on the side away from the mounting surface.

[0009] Furthermore, in a preferred configuration, a slot is provided inside the lamp housing at the extension ring, and a sealing groove is provided inside the slot at the corresponding airbag.

[0010] The beneficial effects of this utility model are as follows: In this invention, a vehicle lamp is assembled by combining a lamp housing, a lamp cover, and lighting components. A groove on the lamp cover's extended ring engages with an inflatable airbag, and a sealing groove is provided at a corresponding position on the lamp housing. After the lamp cover and lamp housing are installed, the airbag is inflated, causing it to actively expand and tightly fit the sealing groove. This ensures the airtightness of the assembled lamp housing and lamp cover, preventing external moisture from entering and ensuring the waterproof performance of the vehicle lamp.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-5A waterproof vehicle light includes a lamp housing 11, an internal lighting component 13, and a lamp cover 12 sealed and snapped onto the lamp housing 11. An extension ring is provided on the side of the lamp cover 12 adjacent to the mounting surface. Three sets of grooves 122 are evenly spaced on the outer wall of the extension ring. An airbag 3 for sealing is fitted outside the grooves 122. An airflow channel 123 for ventilation is provided between two adjacent grooves 122 within the extension ring. An air inlet 121 is provided on the side of the lamp cover 12 away from the mounting surface at the corresponding airflow channel 123. A transition channel is provided between the air inlet 121 and the adjacent groove 122 within the extension ring. A sealing plug 2 is screwed onto the lamp cover 12 at the air inlet 121. The specific structure, connection method and working principle of the lamp housing 11, the lighting component 13 and the lamp shade 12 are all existing technologies that are currently publicly available on the market. The lamp shade 12 is provided with a sealing component on the side adjacent to the mounting surface and outside the extension ring. Furthermore, the outer wall of the extension ring is provided with a sealing gasket between the two adjacent airbags 3 (not shown in the figure).

[0015] The sealing plug 2 has a threaded portion, and a groove 21 is formed on the end face of the sealing plug 2, with a handle inside the groove 21. A sealing cavity is formed on the side of the lampshade 12 away from the mounting surface, located at the sealing plug 2, and a threaded groove adapted to the threaded portion is provided within the sealing cavity. When the sealing plug 2 is threadedly connected to the sealing cavity, the end face of the sealing plug 2 is flush with the end face of the lampshade 12 away from the mounting surface. A retaining groove is formed inside the lamp housing 11 at the extension ring, and a sealing groove 111 is formed within the retaining groove at the corresponding airbag 3.

[0016] In this embodiment, the extended ring of the lampshade is aligned with the annular groove inside the lamp housing 11 and inserted. Before installation, the airbag 3 should be in an uninflated or deflated state, small in size and flexible, so as to be easily inserted into the groove of the lamp housing. Then, the lampshade is pressed smoothly into the lamp housing. After the lampshade and the lamp housing are sealed and snapped together, its airbag 3 is exactly located in the corresponding sealing groove 111 area on the lamp housing.

[0017] Unscrew the sealing plug 2 screwed onto the air intake 121, and use an inflation tool to align with the air intake 121. Slowly and steadily inject air into the air intake 121 through the inflation tool. After the injected air passes through the air intake 121, it flows sequentially along the transition channel, the adjacent groove 122, and into the airbag 3. At the same time, some air will flow into the adjacent groove of the lamp housing 11 through the adjacent airflow channel 123. After all the airbags are inflated, quickly remove the inflation tool and immediately align the sealing plug 2 with the air intake 121 and tighten it to ensure that its end face is flush with the outer surface of the lamp housing. At this time, the airbag 3 remains inflated and is locked into the sealing groove 111, forming a tight seal in the sealing groove 111. The entire vehicle lamp assembly is now complete.

[0018] The inflated airbag expands and tightly fills and compresses the entire space of the sealing groove 111, forming a uniform and self-adaptive sealing ring. The expansion pressure of the airbag also strengthens the connection between the lampshade and the lamp housing.

[0019] In this invention, a vehicle lamp is assembled by combining a lamp housing, a lamp cover, and lighting components. The lamp cover extends from a ring and has a groove that engages with an inflatable airbag. A sealing groove is provided at a corresponding position on the lamp housing. After the lamp cover and lamp housing are installed, the airbag is inflated, causing it to expand actively and fit tightly against the sealing groove. This ensures the airtightness of the assembled lamp housing and lamp cover, prevents external moisture from entering, and ensures the waterproof performance of the vehicle lamp.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
