Description

Technical Field

[0001] This utility model belongs to the automotive field, and in particular relates to a warning light for a car rearview mirror. Background Technology

[0002] There are several areas in a car that cannot be directly or indirectly observed through the rearview mirror while driving; these are called blind spots. To improve driver safety, some cars are equipped with warning lights in the blind spots to alert drivers when changing lanes. Traditional blind spot warning lights, such as those shown in Chinese utility model patent No. CN 209756944 U, include a lamp holder and a circuit board inside the lamp holder. One side of the lamp holder has a light-transmitting surface, and the other side has a sealing adhesive. A diffusion film is adhered to the light-transmitting surface. This type of blind spot warning light is prone to water leakage at the joint between the light-transmitting surface and the lamp holder. To address this issue, the applicant previously applied for a Chinese utility model patent entitled "A Waterproof Car Blind Spot Warning Light," with authorization number CN 213019468 U. Its solution involves providing an inner flange at the lower end of an outer lens, embedding the inner flange into the lamp holder, and fixing it by laser welding. However, there are still some drawbacks: 1. Due to the thickness of the inner flange, there are problems such as long welding time and uneven welding; 2. The LED light circuit board has poor installation stability and is easy to loosen. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a car rearview mirror warning light that is easy to weld and has better stability and waterproof performance.

[0004] To solve the above problems, the technical solution adopted by the utility model includes: a base, an LED circuit board disposed in the base, and a light-transmitting mirror covering the upper end of the base. The LED circuit board is connected to a wire leading out from the wiring hole of the base. The base is characterized in that: the upper end of the base is provided with a welding plane, the lower end of the light-transmitting mirror is provided with a closed fusion thin edge corresponding to the welding plane, and both ends are provided with first positioning grooves. The base is integrally formed with a positioning buckle embedded in the first positioning groove.

[0005] The aforementioned car rearview mirror warning light is characterized in that: the cross-section of the fused thin edge is triangular.

[0006] The aforementioned car rearview mirror warning light is characterized in that: the positioning buckle has a tapered surface at the upper end and a mounting platform at the lower end.

[0007] The aforementioned car rearview mirror warning light is characterized in that: the inner cavity of the base is provided with circumferentially arranged retaining ribs, the LED light circuit board is secured to the bottom of the base by the retaining ribs, and the sides of the light-transmitting mirror are provided with positioning posts that abut against the LED light circuit board.

[0008] The aforementioned automotive rearview mirror warning light is characterized in that: a sealing ring is provided in the wiring hole of the base to seal with the wire.

[0009] The car rearview mirror warning light is characterized in that: the end of the wire is provided with a connector, and the connector is provided with symmetrical elastic buckles on both sides.

[0010] The aforementioned car rearview mirror warning light is characterized in that: a second positioning groove is provided at the end of the base.

[0011] The advantages of this utility model of car rearview mirror warning light are as follows: 1. The light-transmitting mirror is laser welded to the welding plane of the base through a closed fusion thin edge and positioned by a positioning structure, which has the advantages of short welding time, precise welding position and more uniform welding surface, thereby improving waterproof performance; 2. After the LED light circuit board is connected by the clamping rib, it is positioned by the positioning column, which can effectively prevent loosening.

[0012] The utility model will be further described below with reference to the accompanying drawings. Attached Figure Description
