[0019] The utility model is further illustrated by the following examples, but not as the limitation of the utility model. The specific experimental conditions and methods not noted in the following examples are usually the conventional means familiar to the skilled in the art.

[0020] As Figs. 1 to 3The application discloses a motor vehicle road light navigation device, which is characterized by comprising a detachable fixing frame 1, a laser projection device 2 connected to the fixing frame, and a shell, a reading module, an intelligent processing module, an output module, a signal module, a laser, a galvanometer, a lens, and a light shield selector of the laser projection device. Preferably, the lens comprises a first lens and a second lens. The fixing frame is detachably installed on a vehicle or the back of a rearview mirror. The laser projection device projects the navigation route data displayed by a navigation device to the front road surface of the motor vehicle after processing. The reading module reads the navigation route data on the navigation device through wired or wireless connection and transmits the real-time route data on the navigation device to the intelligent processing module. The intelligent processing module processes the route data on the navigation device and transmits the processed data to the laser and the light shield selector through the transmission module.

[0021] The laser generates a light beam to irradiate the first lens. Preferably, the first lens is a collimating lens, which converges the divergence angle of the light beam emitted by the laser, and the light beam passing through the first lens becomes a parallel light beam. The parallel light beam irradiates the galvanometer, which deflects the light beam to scan an image. Preferably, the galvanometer is a two-dimensional scanning galvanometer, and the parallel light forms an image through the galvanometer. The image formed by a single two-dimensional scanning galvanometer is a two-dimensional plane image, or a plurality of two-dimensional scanning galvanometers can be combined to form a three-dimensional image. The light beam forming the image irradiates the road surface through the second lens. Preferably, the second lens is one of a reflective binary diffraction surface lens, a reflective spherical mirror, a reflective Fresnel lens, a reflective aspherical mirror, a reflective free-form surface lens, or a reflective multi-combination lens group.

[0022] Since the icon projected by the laser projection device 2 on the road surface has no directivity at this time, it cannot be matched with the navigation icon on the navigation device, so a light shield selector is arranged between the laser and the first lens. When the navigation icon on the navigation device shows straight ahead, the intelligent processing module transmits the straight ahead icon data of the navigation device to the light shield selector. At this time, the light shield selector also selects a light shield with a shape of a straight ahead icon accordingly. When the navigation icon on the navigation device is a left turn or right turn icon, the light shield selector will select a left turn or right turn icon accordingly. The selection of the shape of the light shield is kept synchronized with the icon on the navigation device. Thus, when the driver drives the motor vehicle on the road surface, the driver drives according to the laser projection route icon on the road surface, avoiding the driving risk caused by the driver's eyes constantly switching between the display screen in the navigation device and the road conditions, and can drive according to the laser projection route icon on the road surface at any road section. The risk of the driver looking at the display screen in the navigation device and the road conditions is avoided, the attention of the driver is improved, the driving risk is avoided, and the driving safety and comfort are improved. At the same time, the problem of easily entering the wrong intersection and the driver making a wrong judgment at a dense and complex intersection is solved. Because the projected laser route icon is on the road surface in front of the motor vehicle, the driver can see the road conditions in front while looking at the road icon, and the safety of driving is further improved.

[0023] In some relatively dense road sections, the traffic is relatively large, and the distance between the cars is relatively short. The projected laser route icon may be projected on the front car, which may affect the driver of the front car. Therefore, the laser projection device is also provided with a laser ranging device. The laser ranging device measures the distance between the laser route icon on the road surface and the laser projection device. For convenience of statement, this distance is named as the comparison distance. When the actual distance measured by the laser ranging device is less than the comparison distance, the laser route icon has been projected on the front car. At this time, the laser projection device is closed. When the actual distance measured by the laser ranging device is equal to the comparison distance, the laser projection device is opened.

[0024] The light source generated by the laser is relatively small, and the pattern projected on the road surface is also small and not easy to see. In order to realize that a small light source can project a large pattern, the optical distance from the galvanometer to the second lens can be adjusted according to the actual needs. The optical distance is between 1-2 times the focal length of the second lens, so that the laser route icon with the desired size is obtained.

[0025] Further, when the distance measured by the laser ranging device is smaller than the comparative distance, so that the laser projection device is closed, in order to enable the driver to continuously know the road surface information in front, the fixed frame is further provided with a device frame 3, which can be placed according to the personal habits of the driver. Get rid of the conventional fixed mode that the device support is placed on the center console, and give the driver more choices.

[0026] Further, in order to further perfect the function of the utility model, the laser projection device can be further provided with a human body sensing device, and when pedestrians are sensed in front, the laser projection device is closed to avoid laser projection into the eyes.

[0027] The above is only a specific implementation of the utility model. However, the protection scope of the present application is not limited to this. Any change or simple replacement without creative labor should be covered in the protection scope of the present application.
