[0020] The present application will be further described as follows in conjunction with the accompanying drawings. Figs. 1 to 5 The present application will be further described as follows in conjunction with the accompanying drawings.
[0021] A rear bumper warning light is used to be installed on the rear bumper or rear spoiler, and the corresponding light is switched through linkage with vehicle operation, for example, bright red light when braking, bright white light when reversing, and constant red light when turning on the running light, so as to enhance the transmission effect of the original vehicle light signal, and thus improve the safety of the vehicle during driving. The rear bumper warning light comprises a bottom shell 1, a connection wire harness 2, a light source plate 3, a light source plate support 4, a light uniformizing film 5, a light shielding plate 6, a light guide body 7, and a mask 8.
[0022] The bottom of the bottom shell 1 is provided with three air holes 11 and a wire hole 12 for connecting the wire harness 2, the air holes 11 are opposite to the light source plate 3 for dissipating the heat generated by the light source plate 3 during the light emitting process, and at the same time, in order to ensure the waterproof and dustproof performance, the air holes 11 are all closed by the waterproof film 9, realizing the effect of air permeability and water resistance. At the same time, two screws 13 are pre-embedded in the bottom shell 1 during the injection molding production process, which are used for connecting and fixing with the vehicle rear bumper or rear spoiler; the connecting wire harness 2 includes a power line and a control signal line, one end of which is connected with the light source plate 3, and the other end is drawn out from the bottom shell 1, the power line supplies power to the light source plate 3, and the control signal line receives the linkage signal of the vehicle operation.
[0023] The light source plate 3 is arranged between the bottom shell 1 and the light source plate support 4, and is tightly fixed on the bottom shell 1 by the light source plate support 4, and the light source plate support 4 is provided with a light uniformizing film 5. Specifically, the edge of the light source plate support 4 is provided with a plurality of limiting plates 41 bent towards the rear side, the bottom shell 1 is provided with a plurality of limiting bodies 14 for limiting the light source plate 3, and the edge of the light source plate 3 is provided with a clamping interface 31 clamped with the limiting body 14. During installation, the clamping interface 14 of the light source plate 3 is aligned with the limiting body 14 in the bottom shell 1 for clamping, and then the light source plate support 4 is pressed on the light source plate 3 and the limiting plate 41 is overlapped on the edge of the light source plate 3 for further limiting. Thus, the light source plate 3 is limited in the bottom shell 1 and the light source plate support 4 through the cooperation of the limiting body 14, the clamping interface 31 and the limiting plate 41, avoiding displacement due to bumping during driving. In addition, in order to ensure the light emitting effect, the light source plate support 4 is made of colorless transparent pc material.
[0024] The light guide body 7 is arranged between the light source plate 3 and the face cover 8, and is made of colorless transparent engineering plastic, which is used for directional light guiding of the light from the light uniformizing film 5, so that the light is more stereoscopic. The light source plate 3 and the light guide body 7 are provided with a light shielding plate 6, the light shielding plate 6 is provided with a hollow part 61 for the light to pass through, so as to shield the area outside the hollow part 61. Specifically, the light shielding plate 6 is made of black ABS material, which mainly performs directional shielding of the light, highlights the light modeling profile, and has an aesthetic effect.
[0025] In this embodiment, the light guide body 7 includes a plurality of light guide blocks 71 corresponding to the hollow parts 61 one by one, the light guide blocks 71 have the same shape as the corresponding hollow parts 61, and gaps 72 are left between the light guide blocks 71, so as to highlight the light modeling profile, and realize more rich light modeling through the combination of the light guide blocks 71.
[0026] Further, the light exit surface of the light guide block 71 is provided with a light exit body array composed of block-shaped protrusions 73, and the thickness of the light guide block 71 is largest at the vertical geometric central axis Z1 of the light guide body 7 and decreases towards both sides, so as to make the light effect more stereoscopic, increase the effective output range of light, and ensure that the light can be clearly observed at the left and right rear of the vehicle. Correspondingly, the main light transmission surface 81 of the mask 8 is adapted to the light exit surface of the light guide body 7, so that the main light transmission surface 81 is divided into left and right inclined light transmission surfaces at the vertical geometric central axis Z2 thereof.
[0027] Further, the mask 8 is made of colorless transparent material and is ultrasonically welded to the bottom shell 1, so as to one-time press and fix all the components in the interior. The welding speed is high in efficiency, and the connection seams can be waterproofed by plastic melting.
