Figure 2 for Figure 1 AA sectional view, which shows the cross-sectional structure of the bumper, as shown Figure 2As shown, an installation space 400 is formed between the bumper body 100 and the grille 200, and the luminous decorative strip 300 is located in the installation space 400. The luminous decorative strip 300 includes a light source 310 and a light-transmitting cover 320. The light-transmitting cover 320 is arranged around the light source 310. A part of the light-transmitting cover 320 is opposite to the flange 110 of the bumper body 100 and serves as the luminous surface 321 of the luminous decorative strip 300. The light emitted by the light source 310 is transmitted from the luminous surface 321 and is reflected by the flange 110 of the bumper body 100 to the outside and observed, thereby forming a lighting effect. Since the light-transmitting cover 320 of the luminous decorative strip 300 is completely hidden in the installation space 400 and cannot be observed, its appearance quality is low.

[0021] In some embodiments, the light source 310 may be a COB (Chip On Board) light source or a PCB (Printed Circuit Board), on which an LED lamp and electronic components (ie, a light-emitting circuit) for making the LED lamp emit light are disposed.

[0022] In some embodiments, the light-emitting decorative strip 300 may further include a decorative strip bracket 330, the light source 310 is fixed on the decorative strip bracket 330, and the decorative strip bracket 330 is fixedly connected to the bumper body 100 and / or the grille 200, and the light-transmitting cover 320 is fixedly connected to the decorative strip bracket 330, and defines a receiving chamber for receiving the light source 310 with the decorative strip bracket 330, so as to protect the light source 310. The light-transmitting cover 320 and the decorative strip bracket 330 may be bonded together by glue, and the receiving chamber is sealed to prevent the light source 310 from being affected by external moisture and the like in its normal operation. In some other embodiments, the light-transmitting cover 320 and the decorative strip bracket 330 may also be welded together.

[0023] In some embodiments, the light-transmitting cover 320 may be fixedly connected to the grille 200 (e.g., bonded), or may be formed as one piece with the grille 200, that is, the light-transmitting cover 320 is a part of the grille 200. When the light-transmitting cover 320 is a part of the grille 200, the light-transmitting cover 320 and the grille 200 may be integrally formed by two-color injection molding. During two-color injection molding, the first shot material is a light-transmitting material, such as milky white or transparent PC (polycarbonate), PMMA (polymethyl methacrylate), etc., to form the light-transmitting cover 320, and the second shot material is an opaque material, such as PC / ABS (a mixture of polycarbonate and ABS (acrylonitrile-butadiene-styrene copolymer)), to form the grille 200; the two are connected together by two-color injection molding to form a grille with a light-transmitting surface on the outer side of the side wall.

[0024] In some embodiments, the outer surface of the grille 200 may be spray-painted or electroplated to form a prefabricated pattern to make it more beautiful.

[0025] In some embodiments, the grille 200 can be connected to the bumper body 100 by snapping. The flange 110 of the bumper body 100 is arranged around the grille 200, and there is a preset gap between the grille 200, so that the light emitted from the light-emitting surface 321 can be emitted from the bumper body 100 after being reflected by the flange 110, so that it can be observed by the observer, forming a more beautiful lighting effect.

[0026] The light source 310 may be connected to a power source of the vehicle so as to be powered by the power source. The light source 310 may also be connected to an electronic control unit of the vehicle so as to realize on / off control of the light source 310 through the electronic control unit.

[0027] In some embodiments, grille 200 may be a mesh grille, a horizontal grille, a vertical grille, a closed panel grille, or any other suitable grille.
