This difference not only increases the installation difficulty, but also may cause the radar position to deviate due to forced installation, affecting its detection accuracy and stability. The traditional fixing method lacks flexibility, and once the fixed part and the docking hole are not matched, it often needs to be reinstalled or modified, which not only increases the installation cost, but also prolongs the installation cycle and reduces the work efficiency. Especially in the automobile after-sales market or personalized modification scene, the rapid and accurate installation of millimeter wave radar becomes a problem to be solved. SUMMARY

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figs. 1-7, the present application provides the following technical solutions: an automatic driving sound wave early warning device, comprising a millimeter wave radar 1, which is installed at the front end of a car when in use. When the car starts the automatic driving mode, the millimeter wave radar 1 will timely feed back the detected information to the automatic driving system of the car, thereby assisting the car to safely drive automatically.

[0023] One side of the millimeter wave radar 1 is provided with a docking port 2, and the back corner end of the millimeter wave radar 1 is respectively provided with a side foot 3. The other end of each side foot 3 is movably installed on the surface of a fixed sheet 4. The inside of the fixed sheet 4 is movably installed with a sliding piece 5.

[0024] One side of the sliding piece 5 is movably connected with one end of an adjusting knob 6. The adjusting knob 6 is screwed through from one end of the fixed sheet 4 into the inside of the fixed sheet 4. One side of the sliding piece 5 is connected with a pad strip 7, which is made of rubber material. The pad strip 7 is also installed in the inside of the fixed sheet 4.

[0025] Preferably, two docking blocks 31 are symmetrically and fixedly installed on the outer wall of the connecting end of the side foot 3 and the fixed sheet 4. The other end of each docking block 31 is fixedly connected with one side of the outer wall of the sliding piece 5. The side of the sliding piece 5 is a "concave" structure. The "concave" end of the sliding piece 5 is movably connected with the outer wall of the pad strip 7.

[0026] When in use, the pad strip 7 is installed between the sliding piece 5 and the fixed sheet 4, so that when the side foot 3 is subjected to a vibration force, the vibration force of the side foot 3 is transmitted to the sliding piece 5, and the pad strip 7 weakens the vibration force transmitted to the fixed sheet 4, thereby playing a role in weakening the vibration force.

[0027] The inside of the fixed sheet 4 is provided with a sliding groove 41, and the inner wall of one side of the sliding groove 41 is also provided with a center groove 42, and the inside of the sliding groove 41 movably installs the butt block 31 and the sliding piece 5, and the inside of the center groove 42 is bonded with the pad strip 7.

[0028] Specifically, when the fixed sheet 4 moves, the sliding groove 41 moves, and the sliding groove 41 moves along the transverse track of the sliding piece 5 and the butt block 31, so that the fixed sheet 4 can adjust the position at the bottom of the side foot 3.

[0029] Preferably, the side wall of the pad strip 7 in active contact with the sliding piece 5 is provided with a semicircular groove 71, one end of the adjusting knob 6 is perpendicular to the "concave" end of the sliding piece 5, and the radius of the adjusting knob 6 is matched with the internal size of the semicircular groove 71.

[0030] Specifically, when the millimeter wave radar 1 is installed on the car through the four groups of side feet 3 and fixed sheets 4, the side feet 3 and fixed sheets 4 on the transverse two sides of the millimeter wave radar 1 can play a positioning effect after being fixed, thereby preventing the millimeter wave radar 1 from shaking left and right.

[0031] Working principle, when the millimeter wave radar 1 is connected with the pre-installed mounting part at the front end of the car through the four fixed sheets 4 on the back of the millimeter wave radar 1, there may be a situation that the butt joint hole on part of the fixed sheet 4 and the corresponding butt joint hole at the front end of the car have a transverse position deviation. In view of this potential problem, the technical scheme provides the following solutions.

[0032] The specific operation is as follows: once the fixed sheet 4 with position deviation is found, the adjustment can be started. The adjustment process is through the adjusting knob 6 on the corresponding side of each fixed sheet 4. According to the specific direction and degree of the transverse position deviation, the adjusting knob 6 is operated. If adjustment is needed, the adjusting knob 6 can be smoothly moved from the inside of the fixed sheet 4 to the outside. This structural operation will loosen the side of the fixed sheet 4 to the one side of the sliding piece 5, thereby allowing the fixed sheet 4 to realize a certain degree of horizontal displacement on the side foot 3.

[0033] Through the adjustment of the structure, the fixed sheet 4 docking hole which originally can not be smoothly docked due to deviation can be easily and accurately aligned with the docking hole of the front end of the automobile. This structure not only greatly facilitates the installation process of the millimeter wave radar 1, but also reduces the repeated debugging work caused by inaccurate docking.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of the present application.
