The advantages, features and methods of the invention may be understood more clearly by reference to the following detailed description of the embodiments taken in conjunction with the accompanying drawings.
The present invention provides a vehicle lamp, which is assembled on one side of a back door or a vehicle body of a vehicle.

For the reflecting bowl, the reflecting bowl of the steering lamp of the vehicle, the reflecting bowl of the fog lamp, the reflecting bowl of the brake lamp, the reflecting bowl of the hazard warning flash lamp and the reflecting bowl of the width indicating lamp share the same shell or do not share the same shell. Whether or not the two are shared in particular can be designed according to specific requirements.
The lamp in the embodiment can realize a reversing prompt function and an additional ground warning function required by regulations.
The first pattern is formed by diffusely reflecting light emitted by the LED light source of the reversing light by the reversing light reflecting structure, and the second pattern is formed by specularly reflecting light emitted by the LED light source of the warning light by the warning light reflecting structure; that is, the light receiving surface of the reversing light reflecting structure is provided with a plurality of grid-shaped reflecting surfaces; the surface of the warning lamp reflecting bowl structure for receiving light is a smooth curved surface, so that the brightness of the formed second pattern is far greater than that of the first pattern.
The cooperation of the backup lamp LED light source and the backup lamp reflecting structure realizes the backup lamp prompting function required by regulations; the cooperation of this warning light LED light source and warning light reflection configuration realizes this embodiment's newly added warning function that shines on ground.
The switching of the backup light LED light source and the warning light LED light source is realized through the control of a controller. Specifically, rear cover plate and other structures are mounted on the rear side of the shell, a control panel is mounted on the rear cover plate and is respectively connected with the reversing light LED light source and the warning light LED light source, a wire harness plug-in connector is arranged on the rear cover plate, and the wire harness plug-in connector is used for connecting the control panel with a whole vehicle wire harness to realize control signal input and whole vehicle power supply input. The assembly of the housing, the back cover plate and the control panel can be realized by referring to the assembly of related components in the prior art.
In this embodiment, the first pattern formed by diffuse reflection of the backup light reflecting structure is farther from the vehicle than the second pattern formed by specular reflection of the warning light reflecting structure. In order to achieve the effect, the control is achieved according to the included angle of the reversing light reflecting structure relative to the Y direction of the whole vehicle and the included angle of the warning light reflecting structure relative to the Y direction of the whole vehicle.
As shown in fig. 1, in this embodiment, a first backup light reflecting structure 1, a first warning light reflecting structure 2, a second warning light reflecting structure 3 and a second backup light reflecting structure 4 that are arranged along the Y direction of the whole vehicle are formed on the reflecting bowl; the warning light LED light sources comprise a first warning light LED light source 21 assembled on the first warning light reflecting structure 2 and a second warning light LED light source 31 assembled on the second warning light reflecting structure 3, and the reversing light LED light sources comprise a first reversing light LED light source 11 assembled on the first reversing light reflecting structure 1 and a second reversing light LED light source 41 assembled on the second reversing light reflecting structure 4;
in the whole car X direction, first warning light reflecting structure 2 is located behind the second warning light reflecting structure 3, first back-up light reflecting structure 1 is located before first warning light reflecting structure 2, and is located behind the second warning light reflecting structure 3, second back-up light reflecting structure 4 with first back-up light reflecting structure 1 flushes. By virtue of such an arrangement, the first pattern and the second pattern that are finally presented are located in a centered position behind the vehicle, and the first pattern is behind the second pattern.
Since the first backup light reflecting structure 1, the first warning light reflecting structure 2, the second warning light reflecting structure 3 and the second backup light reflecting structure 4 are arranged along the whole vehicle Y direction, the positions of the first backup light reflecting structure 1, the first warning light reflecting structure 2, the second warning light reflecting structure 3 and the second backup light reflecting structure 4 in the whole vehicle Z direction are flush, so that the size of the lamp in the whole vehicle Z direction can be minimized; meanwhile, the size of the lamp in the whole vehicle Y direction can be minimized by adjusting the angles of the first reversing light reflecting structure 1, the first warning light reflecting structure 2, the second warning light reflecting structure 3 and the second reversing light reflecting structure 4 relative to the whole vehicle Y direction and the reflecting surface in the surface for receiving light on the reflecting structure.
The first backup lamp reflecting structure 1, the first warning lamp reflecting structure 2, the second warning lamp reflecting structure 3 and the second backup lamp reflecting structure 4 are integrally formed.

The specific shape of the first light spot area B11 to the fourth light spot area B22 may be changed through a modeling design, and the specific shape is realized through adjusting the angles of the first warning light reflecting structure 2 and the second warning light reflecting structure 3 relative to the Y direction of the whole vehicle. In this embodiment, in order to achieve that the first light spot area B11 is closer to the vehicle than the third light spot area B21, and the second light spot area B12 is closer to the vehicle than the fourth light spot area B22, the first warning light reflecting structure 2 needs to be disposed further to the rear than the second warning light reflecting structure 3 in the X direction of the whole vehicle, that is, the lower intersection points of the left and right side reflecting portions of the first warning light reflecting structure 2 are further to the rear than the lower intersection points of the left and right side reflecting portions of the second warning light reflecting structure 3; the position relation of the lower intersection point of the first warning light reflecting structure 2 and the second warning light reflecting structure 3 on the whole vehicle coordinate axis is specifically designed according to the vehicle size parameter, the position relation is exemplified by specific vehicle data, and the lower intersection point of the first warning light reflecting structure 2 is X-10 mm, Y-19 mm and Z-0.

The first warning light reflecting structure 2 and the second warning light reflecting structure 3 realize the light distribution of the region B (namely the region corresponding to the second pattern), and the included angle (acute angle) formed by the first warning light reflecting structure 2 and the horizontal plane (the whole vehicle Y direction) is smaller than the included angle formed by the second warning light reflecting structure 3 and the horizontal plane (the whole vehicle Y direction), so that the light spots formed by the reflection of the first warning light reflecting structure 2 are closer to the vehicle; in addition, the maximum curvature of the first warning light reflecting structure 2 is smaller than the minimum curvature of the reflecting structure of the second warning light reflecting structure 3 to concentrate the light of the first warning light LED light source 21 closer to the vehicle.

The first light spot area B11 is closer to the vehicle than the third light spot area B21, and the second light spot area B12 is closer to the vehicle than the fourth light spot area B22; the first to fourth spot areas B11 to B22 collectively form the second pattern.
The light diffusely reflected by the first backup light reflecting structure 1 and the second backup light reflecting structure 2 overlaps in the area a in fig. 4, i.e. forms the first pattern.
