Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In a basic embodiment of the present invention, as shown in fig. 1 and 4, the present invention provides a vehicle contour display system, including a projection image display module, a projection position adjustment module, and a control module; the projection position adjusting module is internally provided with a reflector 1 capable of rotating around a rotating shaft, and the reflector 1 is suitable for reflecting the image emitted by the projection image display module to the ground around the vehicle body; the control module is electrically connected with the projection position adjusting module so as to control the rotation angle of the reflector 1; the control module is electrically connected with the projection image display module so as to control the output power of a projection light source of the projection image display module and the size and shape of a target image.

Specifically, the projection position adjusting module adjusts the projection position of the target image on the ground by adjusting the rotation angle of the reflector 1. More specifically, the mirror 1 may be connected to a driving device, and the projection position adjusting module may control the rotation angle of the mirror 1 by controlling the rotation angle of the driving device, thereby further controlling the projection position of the target image around the vehicle body. The driving device may be a stepping motor or a structure or a machine that can drive the mirror 1 to rotate by a specific angle.

The control module can adopt an existing controller which can be used for processing information and controlling the operation of each mechanism element, preferably a vehicle Body Controller (BCM), and can control the power of the laser output by the laser light source unit, namely the brightness of a target image finally irradiated to the periphery of a vehicle body. The projection position of the target image can be preset, and can be self-adaptive to be adjusted to a proper position according to the actual situation.

It should be noted that fig. 4 shows an example of a process in which an image emitted through the projection image display module is reflected to a road surface by the reflector 1 in the projection position adjustment module and a projection position of the image changes, and although the light pattern of the image shown in fig. 4 is a rectangle, the light pattern of the emitted image is not limited to the rectangle, but may be other shapes, such as a circle, a trapezoid, a triangle, and even some singular shapes, such as a skeleton pattern, which can better attract the attention of other drivers of vehicles or pedestrians, so as to make the outline showing effect more prominent; the projection of the images may be continuous, forming an integral light pattern around the vehicle body, or may be sequential dynamic images, preferably sequential dynamic images; that is, as long as the projected image can perform the outline-showing function, even if the projected image is somewhat distorted, fig. 6 shows a form of distortion of the projected image without compensation processing; as a preferred embodiment, the light pattern of the outgoing image is rectangular, and further, the brightness and the shape of the outgoing image are consistent; therefore, when the projection position adjusting module works and needs to project and move the image to a specific position, the control module can control the projection position adjusting module to adjust the projection position of the target image on the ground.

In the basic technical scheme, the control module controls the projection position adjusting module to output laser to form static images or dynamic images with different light shapes to be projected onto the ground around the vehicle body, the display position of the projection position adjusting module can be adjusted along with the width of the vehicle body, the outline showing range can be enlarged, other road users can see the outline of the vehicle more easily, the vehicle can be found in advance, and therefore the safety factor in the driving process is effectively improved; the control module can enable the projection image to move along the direction of the vehicle body by controlling the projection position adjusting module, so that the outline of the vehicle can be clearly displayed, meanwhile, the outline displaying range is enlarged, the influence of a display blind area is weakened, and the driving safety coefficient is further improved; meanwhile, the output power of the laser and the size and the shape of the target image can be controlled by controlling the projection image display module, so that the projection image is guaranteed to be always clearly visible in the moving process and cannot be distorted.

The projection image display module can adopt a multi-pixel light source, and the color, the shape and the size of a projection image emitted by the projection image display module are controlled by respectively controlling the color and the brightness of each pixel light source. In an embodiment of the present invention, as shown in fig. 3, the projection image display module includes a laser light source unit and a scanning imaging unit, and the control module is electrically connected to the laser light source unit to control the output power of the laser light source; the control module is electrically connected with the scanning imaging unit to control the size and the shape of the target image. The scanning imaging unit can adopt the existing MEMS (micro electro mechanical system) micro-mirror or DMD (digital micro-mirror), preferably, the MEMS micro-mirror, after the laser irradiates on the MEMS micro-mirror, according to different control programs, the micro-mirror adjusts the angle at high speed in the fast and slow axis directions, and the laser reflected by the MEMS micro-mirror forms images with different shapes and sizes. Specifically, the laser light source unit outputs modulated light signals according to a time sequence, the scanning imaging unit adopts a progressive scanning mode or a vector scanning mode, the control module controls the angle and the frequency of the MEMS micro-mirror, each pattern has different control programs and parameters thereof, and the different control programs comprise electric circuit control. Preferably, in order to effectively improve the light efficiency, a laser collimation unit is arranged between the laser light source unit and the scanning imaging unit, as shown in fig. 3, wherein the laser collimation unit may be an optical element capable of converging light, such as a focusing lens, a collimator, and the like.

When the projection position adjusting module works, the projection position of a target image around a vehicle body is preset, the control module controls the rotation angle of the reflector 1 to project the target image onto the corresponding projection position, or the projection position adjusting module directly projects the target image onto the ground around the vehicle; when the projection position of the target image needs to be moved, the control module calculates the angle of the reflector 1 needing to be rotated according to the position of the projection image needing to be moved, and then controls the reflector 1 to rotate to the corresponding angle, so that the movement of the projection position of the target image is realized. In the process, the control module can also calculate the output power of the light source and the size and the shape of the target image according to the projection position, so that the phenomenon of image distortion or uneven light shape of the projected image in the process of moving the projection position of the target image is prevented.

Specifically, taking the whole vehicle contour display system as an example, the position of the projected image moves along the vehicle body direction in the whole process, and moves from one position to another position, and the preset projection position refers to the another position. The control module confirms the rotation angle of the mirror 1 according to the transformation of the two positions.
