Detailed ways

In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to FIG. 2 for details. FIG. 2 is a schematic structural diagram of the front-view camera according to the present invention. As can be seen from FIG. 2 , the front view camera includes a lens mount 101 , an imaging chip 102 , and a circuit board 103 . Moreover, the imaging chip 102 is connected to the circuit board 103 and is located in the lens holder 101; the above are all prior art, and will not be repeated here.

In the embodiment of the present invention, the front-view camera also includes a lens module installed on the lens mount 101, and the lens module includes an optical lens installed in the lens mount corresponding to the position above the imaging chip 102. The lens 100 , the prism 201 arranged above the optical lens 100 , and the light shield 204 arranged between the optical lens 100 and the prism 201 are used to prevent the light reflected by the prism 201 from interfering with each other.

Wherein, the lens module is connected to the imaging chip 102, the optical image imaged by the lens module is converted into a digital signal by the imaging chip 102, and the digital signal is transmitted to the circuit board 103.

Preferably, the front-view camera shown in FIG. 2 is used to eliminate blind spots on both sides of the front of the car. The realization principle is as follows; On the reflective surface 207 , according to the principle of light reflection, the light from the area 203 of the front left headlight is reflected to the area 205 of the optical lens 100 . Similarly, light from the area 202 of the front right headlight passes through the reflective surface 208 of the prism 201 and is reflected onto the area 206 of the optical lens 100 .

Since a light shield 204 is provided between the prism 201 and the optical lens 100 , the light reflected by the prism 201 will not interfere with each other, thereby ensuring the clarity and integrity of the imaging. Moreover, the light rays on both sides of the front of the car are reflected on the reflective surface 207 and the reflective surface 208 of the prism 201, so that the present invention changes the viewing angle of the front-view camera in the prior art, so that the two sides of the front of the car are no longer drivers. blind spots of sight.

Further, the lens module transmits the optical image of the reflected light to the imaging chip 102 . The imaging chip 102 encodes the optical image, converts it into a digital signal, and transmits the digital signal to the circuit board 103 .

A vehicle-mounted display connected to the circuit board 103 is installed at a position convenient for the driver to check in the car, more preferably, the vehicle-mounted display in the existing automobile is connected with the described circuit board 103, so that the vehicle-mounted display shows the front of the car The optical images on both sides eliminate the blind spots on both sides of the front of the car, improving the safety of drivers and reducing losses.

Further, the prism 201 is set as a triangular prism, and the apex 209 of the triangular prism 201 is mounted on the optical lens 100 through the reflector 204 adapted thereto. Of course, the conceivable deformation design is that the design of the prism 201 is not limited to a triangular prism, but can use a rectangular prism, a quadrangular prism, a pentagonal prism, etc.; The side light, according to the different prism settings, can obtain more angles of light from the car, thereby solving the visual blind spots generated by the user when driving the car. Its implementation only needs to be able to reflect the light in the required visual blind zone to the optical lens 100 . Moreover, the reflective surface 207 and the reflective surface 208 of the prism can be modified to form a reflective surface divided into three and four, so that the reflective surface can observe images in three or even four directions at the same time.

Of course, a conceivable deformation design is to use the principle of linear propagation of light and the principle of reflection and refraction of light to split the image of the camera multiple times to change the viewing angle of the original camera, so that the present invention can be applied to different occasions.

The present invention also provides a car using the above-mentioned front-view camera, and the lens mount is installed above the car license plate frame or below the car license plate frame or at the front grille of the car or at the front bumper or at the front car logo; it is conceivable What is important is that as long as the lens mount is installed at a position where the object of the present invention can be achieved, it is not limited to the above position. The car using the front-view camera eliminates the blind spots on both sides of the front of the car in the existing car technology, thereby improving driving safety, and the realization of its function does not require additional additional cameras, reducing the installation and maintenance of the car Burden, has a better market prospect.

Below in conjunction with Fig. 3, the realization of the present invention to eliminate the blind spots on both sides of the front of the vehicle will be further described. Fig. 3 is a flow chart of a preferred embodiment of the present invention to eliminate the blind spots on both sides of the front of the vehicle.

First enter step 301, prism 201 reflects the light on both sides of the front of the car to the optical lens 100, so as to obtain the imaged optical images on both sides of the front of the car; , become the visible area 203 and the visible area 202 in the present invention; the visible area 203 and the visible area 202 can eliminate the blind spots on both sides of the front of the vehicle.

Step 302, converting the optical image encoding of the lens module into a digital signal through the imaging chip 102;

Step 303, the imaging chip 102 transmits the digital signal to the circuit board 103;

Step 304 , through a vehicle-mounted display connected to the circuit board 103 , decode the digital signal to display the optical images formed on both sides of the front of the vehicle.

That is, by adopting the method of the present invention, the images on the left and right sides of the front of the car can be observed through the on-board display, thereby eliminating the blind spots of the left and right headlights in front of the car and improving the safety during driving.

In summary, the present invention utilizes the prism in the lens module to eliminate the blind spots on both sides of the front of the car, so that the user can see the images on both sides of the front of the car on the vehicle display at the same time, improving driving safety. Moreover, the present invention is easy to realize, and only needs to install one camera to realize the requirement of observing images on both sides of the front of the vehicle at the same time, greatly reduces the cost, is easy to install, and is convenient to implement.

It should be understood that the application of the present invention is not limited to the above examples, and those skilled in the art can make improvements or transformations according to the above descriptions, and all these improvements and transformations should belong to the protection scope of the appended claims of the present invention.
