Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate description of the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Examples

As shown in fig. 1 to 5, the plastic bumper with backlight of the embodiment includes: the bumper body 1 is a PP bumper body and is a non-light-transmitting bumper body, and is provided with a hollowed-out identification area 2; the light-transmitting mark 3 is matched with the hollowed-out mark area 2 in an embedding way and is a PP light-transmitting mark; the light source 4, bumper body 1, printing opacity sign 3, light source 4 set gradually, the light that light source 4 sent towards printing opacity sign 3. Through the design, the PP bumper body and the PP light-transmitting mark have good toughness, and can absorb collision energy well after low-speed collision, so that the safety of pedestrians is protected; the light-transmitting mark is matched with the hollowed-out mark area in an embedding way, so that the tightness of the hollowed-out mark area is ensured, and the light of the light source cannot be transmitted out of the gap, so that the display effect of the hollowed-out mark area is affected.

Further, the light-transmitting mark 3 is a light-transmitting mark formed by two-time injection molding. Through the design, the PP light-transmitting mark is formed by adopting a secondary injection molding process, namely, when the bumper body 1 is formed, the insert sliding block is in an ejection state, after the injection molding of the bumper body 1 is completed, the sliding block retreats, a secondary injection molding cavity is reserved, the light-transmitting PP material is injected, the mark required by the forming and the like; the benefit of the two-shot molding is that there is no gap at the interface between the two materials, and the outer surface of the bumper body 1 is a continuous smooth surface, so that the overall molding of the product is not affected.

Specifically, the light source 4 includes a mounting bracket 5 and an LED lamp bead 6 disposed in the mounting bracket 5. By such design, the purpose of irradiating light to the light-transmitting mark 3 is achieved; the LED lamp beads 6 can provide light with various colors and various brightness; and the charging percentage display of the new energy automobile can be realized by adjusting the opening and closing of each LED lamp bead 6.

Specifically, the mounting bracket 5 is fixedly connected with the light-transmitting mark 3 or the bumper body 1, and the LED lamp beads 6 are arranged between the mounting bracket 5 and the light-transmitting mark 3. By such a design, the purpose of fixing the position of the light source 4 is achieved.

Specifically, the mounting bracket 5 is detachably and fixedly connected with the light-transmitting mark 3. Through such design, if broken takes place for LED lamp pearl 6, removable fixed connection is convenient for the change of LED lamp pearl 6.

Specifically, a clamping block 7 and a bayonet 8 which are matched in a clamping manner are arranged between the mounting bracket 5 and the light-transmitting mark 3. By such design, the installation of the installation bracket 5 is convenient; as an equivalent alternative, a detachable fixing connection manner such as a threaded connection may be adopted.

Further, the bumper body 1 is provided with a license plate mounting area 9. By such a design, license plate installation of the bumper body 1 is facilitated.

Further, the bumper body 1 is provided with a headlight installation cavity 10. By such design, the installation of the headlight is facilitated.

Further, the hollowed-out identification area 2 is arranged above the license plate installation area 9. Through such design, compare in fretwork identification zone 2 setting in the below of license plate installation zone 9, fretwork identification zone 2 sets up more conspicuous in the top of license plate installation zone 9, and the display effect is better.

Further, the bumper body 1 is provided with an interface 11 or a joint block 12 for facilitating its mounting on a vehicle body. By such design, the installation and the disassembly of the bumper body 1 are facilitated.

Furthermore, a sealing ring is clamped between the light-transmitting mark 3 and the mounting bracket 5. Through such design, the whole waterproof sealing performance of the product is ensured.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
