BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a license plate having a reverse alarm device, more particularly to a license plate frame comprising a reverse alarm device with reverse alarm radar and a vehicle reverse monitoring camera mechanism to improve the practicability of the product and the safety of the user when reversing a motor vehicle. 
     2. Description of the Related Art 
     As we know that when drivers reverse their motor vehicles, they usually make use of the rear mirrors on both sides of a motor vehicle for viewing. However, the rear mirror has a limited viewing angle, and there are blind spots. These blinds spots are potential dangers during the reverse of a motor vehicle. To improve such method of reversing motor vehicles by rear mirrors, there are devices having radar installed at the rear part of a car in the market, but there are still limitations by purely using reverse radar because there is limitation in searching angle and distance, and furthermore the reverse radar is generally installed on the bumper at the rear of the car, which would be easily damaged by collision. 
     In view of the shortcomings of the prior art mentioned above, which are the subjects of improvements for a long time, hence the inventor of the present invention based on years of experience accumulated from the engagement in the related industry conducted extensive research to resolve the foregoing shortcomings and invented license plate having a reverse alarm device according to the present invention. 
     SUMMARY OF THE INVENTION 
     Therefore, the primary objective of the present invention is to provide a license plate having a reverse alarm device, more particularly to a license plate frame comprising a reverse alarm device with reverse alarm radar and a vehicle reverse monitoring camera mechanism to improve the practicability of the product and the safety of the user when reversing a motor vehicle. 
     To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and its performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiment. The description is made with reference to the accompanying drawings, in which: 
     FIG. 1 shows the three-dimensional assembly structure of the present invention. 
     FIG. 2 shows the three-dimensional disassembled parts of the structure of the present invention. 
     FIG. 3 is a reference diagram showing the assembly structure of the present invention when it is in use. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to FIGS. 1 and 2. The license plate having a reverse alarm device comprises a license plate frame  1 , a reverse radar  2 , a fixed monitoring camera mechanism  3 , an adjustable monitoring camera mechanism ( 4 ) and a support module  5 ; wherein the license plate frame  1  is a whole framework having a cylindrical support  11  protruded from both lateral ends on the upper edge of the cylindrical support  11 , and the a sectional hole  12  is disposed inside the cylindrical support  11 . A hollow long groove hole  13  is disposed in the middle of the upper edge of the license plate frame  1  and the lower edge of the license plate frame  1  is a hemispherical casing  14  having a hollow space in its interior, and a circular hole groove  15  is disposed at one side of the front edge of the hemispherical casing  14  and an elliptical hole groove  16  on the other side. 
     The reverse radar  2  is installed in the hole groove  12  of the support  11  at the upper edge on both ends of the license plate frame  1 . The fixed monitoring camera mechanism  3  is installed and coupled to the hemispherical casing  14 , and the camera in the front end of the fixed monitoring camera mechanism  3  is screwed onto the circular groove  15  at a lateral side of the front edge of the hemispherical casing  14 . Such adjustable monitoring camera mechanism  4  is in cylindrical shape being installed to an elliptical hole groove  16  on the other side at he front edge of the hemispherical casing  14 . The support module  5  comprises a license plate supporting component  51  and a car body support component  52 , and the license plate support component  51  has a penetrating circular hole  53  frame on both lateral sides of the upper edge on the license plate support component  51 , and the car body support component  52  also has a penetrating circular hole on the corresponding sides of the upper edge. A plurality of mutually embedded axial holes are disposed at the bottom side, and an axle  54  passes through the axial holes and can be adjusted to shift and extend to an appropriate angle. Furthermore, the support modules  5  are on the lateral sides on the edge. each having an adjusting washer  55 ., Two screws are used to fix the license plate support component  51  and the car body support component  52 , and the support module  5  is mounted onto the license plate frame  1  by the two screws at the circular hole  53  on both lateral sides of the upper edge of the license support component  51 , so that it combines into an integral license plate having a reverse alarm device. 
     After the components are assembled as described above according to the present invention, please refer to FIG. 3 to mount the license plate  6  on the license plate frame  1  by screws. The support module  5  has an adjusting washer  55 , and the user can install the entire module of components onto the car body by adjusting or loosening the screw  56 , and then fine-tune the license plate frame  1  into an inclined angle according to the actual need. The license plate of the present invention comprises an adjustable monitoring camera mechanism  4 , which allows a larger search and monitoring range. The present invention provides a frame for mounting the license plate, and also has a reverse alarm radar and a monitoring camera mechanism for the motor vehicle reverse alarm device in order to improve the safety during the reverse of a motor vehicle and the practicability of the product. 
     In summation of the above description, the present invention herein enhances the performance than the conventional structure and further complies with the patent application requirements and is submitted to the Patent and Trademark Office for review and granting of the commensurate patent rights. 
     While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
