Through the cooperation of the three ball studs, the metal bracket, the metal cover, and the plastic support plate, fine-tuning of the threads enables adjustment of the installation angle of the millimeter-wave radar, i.e., the horizontal and elevation angles, thereby meeting the requirements for the horizontal and elevation coverage range of the millimeter-wave radar wave, and greatly improving the operability of correcting the radar angle.

Description

Technical Field

[0001] The present invention relates to the special field of radar adjustment brackets, in particular to an adjustable bracket for mounting a vehicle millimeter-wave radar. Background Art

[0002] With the development of society, the popularization of automobiles, and the application of new technologies, people have higher requirements for the operability and safety of automobile driving. FCW, or Forward Collision Warning, is a major highlight in the current automotive application market. Millimeter-wave radar, as a key component, provides drivers with driving safety assurance.

[0003] The forward-facing millimeter-wave radar is installed at the horizontal center of the vehicle's front end, between 500mm and 1000mm above the ground. The radar's elevation and horizontal angles must be within ±1°, and the tolerance must be within ±1°. Such high-precision installation demands extremely high precision from all components, which also creates significant cost pressures. Considering the machining and assembly tolerances of various components, conventional fixed brackets are unlikely to fully meet these installation requirements. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes an adjustable bracket for mounting a millimeter-wave radar for a vehicle.

[0005] An adjustable bracket for mounting a millimeter-wave radar for a vehicle includes a support plate for mounting the radar. A metal bracket capable of meeting the millimeter-wave radar's horizontal and elevation coverage requirements is fixed to the rear end of the support plate via a screw assembly. The screw assembly comprises three sets of ball studs, each of which is provided with a pressure spring capable of adjusting the elevation angle.

[0006] The ends of the screw groups are provided with flat washers and elastic washers, and the ends away from the flat washers and the elastic washers are provided with metal covers for fixing. The screw groups are distributed in a triangular shape.

[0007] The material of the supporting plate is plastic.

[0008] The three ball head bolts are M6 with a pitch of 1mm. The error is corrected by thread fine-tuning. The maximum adjustable angle is ±3°, and one turn of the bolt is 1°.

[0009] The beneficial effects of the present invention are as follows: through the cooperation of three ball bolts, a metal bracket, a metal cover, and a plastic support plate, the thread fine-tuning is used to realize the adjustment of the installation angle of the millimeter-wave radar, that is, the horizontal angle and the pitch angle, which meets the requirements of the horizontal angle and the pitch angle coverage range of the millimeter-wave radar wave, and greatly improves the operability of correcting the radar angle.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below.

[0017] like Figures 1 to 5 As shown, an adjustable bracket for mounting a millimeter-wave radar for a vehicle includes a support plate 3 for mounting a radar 1. The rear end surface of the support plate 3 is fixed with a metal bracket 2 that can meet the horizontal angle and pitch angle coverage requirements of the millimeter-wave radar wave by a screw group. The screw group consists of three sets of ball studs 7, and each ball stud 7 is provided with a pressure spring 4 for adjusting the pitch angle.

[0018] The support plate 3 is used to install the radar 1 through the hexagonal head bolts 5.

[0019] The present invention achieves the installation angle of the millimeter-wave radar 1, that is, the adjustment of the horizontal angle and the pitch angle, by fine-tuning the thread through the cooperation of three ball studs 7, a metal bracket 2, a metal cover 6, and a plastic support plate 3, thereby meeting the requirements for the horizontal angle and the pitch angle coverage range of the millimeter-wave radar wave, and greatly improving the operability of correcting the angle of the radar 1.

[0020] like Figure 3 As shown, the label E in the figure is the product label pasting position, the ball stud 7 at the label B in the figure is used to adjust the pitch angle of the radar 1, that is, the positive pitch angle becomes larger, and the reverse pitch angle becomes larger. The ball stud 7 at the label C in the figure is equipped with a pressure spring 4 and is a fixed position. The ball stud 7 at the label C in the figure is used to adjust the horizontal angle of the radar 1, that is, the angle of the positive rotation radar 1 is biased to the left, and the angle of the reverse rotation radar 1 is biased to the right.

[0021] The ends of the screw groups are provided with flat washers 9 and elastic washers 8, and the ends away from the flat washers 9 and the elastic washers 8 are provided with metal covers 6 for fixing. The screw groups are distributed in a triangular shape.

[0022] The material of the supporting plate 3 is plastic.

[0023] The three ball head bolts 7 are M6 with a pitch of 1 mm. The error is corrected by thread fine-tuning. The maximum adjustable angle is ±3°, and one turn of the bolt is 1°.

[0024] The method of using the present invention is as follows: the radar 1 is fixed to a plastic support plate 3 by a plum-head bolt 5, and three ball screws 7 are arranged in a triangle to connect the metal bracket 2 and the plastic support plate 3. Three metal covers 6 are twisted and riveted on the metal bracket 2 to fix the ball bolts 7. The error is corrected by fine-tuning the thread. The maximum adjustable angle is ±3°. One rotation of the bolt is equal to one pitch of 1°.

[0025] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and description merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
