Description

Technical Field

[0001] This utility model relates to the field of radar calibration technology, specifically a radar calibrator. Background Technology

[0002] Millimeter-wave radar is a type of radar that operates in the millimeter-wave band. Millimeter waves typically refer to the 30–300 GHz frequency range (wavelength 1–10 mm). Since the wavelength of millimeter waves falls between microwaves and centimeter waves, millimeter-wave radar combines some advantages of both microwave and photoelectric radar. It is commonly used in vehicle-mounted radar systems at the front end. However, after a collision, the position of these front-end radar systems tends to shift. Adjustment requires locating the centerline at the rear of the vehicle, placing a laser emitter underneath, and then, after confirming the laser emitter's position is correct, placing an ACC reflector at the front end. Simultaneously, it's crucial to ensure the tire pressure on both sides and the ground surface are aligned before further calibration can proceed. This process is cumbersome. Therefore, a radar calibration instrument is designed to address these issues. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a radar calibrator, comprising: a bottom slide rail 1, a controller and a battery installed in the center of the bottom slide rail 1, a base 2 connected to the lower ends of the left and right sides of the bottom slide rail 1, and adjusting sliders 3 inserted and connected to the lower ends of the front and rear sides of the base 2. The outer side of the adjusting sliders 3 is connected with an arc-shaped array of protrusions. A circular pad 4 is connected to the lower end of the adjusting slider 3, and the pad 4 is inserted and connected to the base 2. A handle 5 is threadedly connected to the upper end of the slider 3, and a plane bearing 6 is connected between the lower surface of the upper end of the handle 5 and the upper surface of the base 2. The left and right sides of the bottom slide rail 1... The upper end of the slider is connected to two calibration lasers 7, the laser emitting ends of the two calibration lasers 7 are vertical. The upper end of the bottom slide rail 1 is connected to the upper slide rail 8. The slider of the upper slide rail 8 is equipped with a radar position calibration laser 12. The front surface of the slider of the upper slide rail 8 is connected to a slot 9 by bolts. A calibration plate 10 is inserted and connected to the front surface of the slot 9. The lower end of the upper slide rail 8 is connected to the middle calibration laser 11. The front emission end of the middle calibration laser 11 is flat. The two calibration lasers 7, the middle calibration laser 11, and the radar position calibration laser 12 are all electrically connected to the controller and battery inside the bottom slide rail 1.

[0025] When using, park the vehicle on a flat surface. Place the bottom slide rail 1 at the front of the vehicle. Raise the radar position calibration laser 12 upwards. The radar position calibration laser 12 contains a laser rangefinder. Align the emission position of the radar position calibration laser 12 with the front-end vehicle radar. The distance between the radar and the radar position calibration laser 12 will be displayed at the top of the radar position calibration laser 12. Adjust the position of the bottom slide rail 1 according to the distance displayed on the radar position calibration laser 12. Then, adjust the position of the two side calibration lasers 7 according to the width of the vehicle. The two side calibration lasers 7 will emit vertical lasers, which will be projected on both sides of the vehicle. The operator can judge whether the position of the bottom slide rail 1 is parallel to the vehicle by the tilt angle of the laser, and thus adjust the position of the bottom slide rail 1. If the vehicle is tilted to one side, the middle calibration laser 11 will emit a horizontal laser line. Twist the handle 5 to untangle the shim 4 and the adjusting slider 3, thereby raising one side of the bottom slide rail 1 upwards so that the laser emitted by the middle calibration laser 11 is horizontal with the vehicle. Insert the calibration plate 10 into the slot 9. Then connect the vehicle to the decoder to perform calibration.

[0026] like Figure 1-4 As shown, this utility model embodiment provides an implementation method in which the laser color of the radar position calibration laser 12 is different from the laser colors of the two side calibration lasers 7 and the middle calibration laser 11.

[0027] Analysis of the above structure shows that the laser color of the radar position calibration laser 12 is different from the laser colors of the two side calibration lasers 7 and the middle calibration laser 11, which can reduce the interference of the laser colors of the two side calibration lasers 7 and the middle calibration laser 11.

[0028] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, plastic sleeves 21 are fitted on both the front and rear ends of the base 2.

[0029] Analysis of the above structure shows that the plastic sleeves 21 fitted at the front and rear ends of the base 2 can reduce the friction of the base 2.

[0030] like Figure 1-4 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, the rear end of the upper surface of the bottom slide rail 1 is marked with a length dimension mark, and the zero point of the length dimension mark is the middle of the bottom slide rail 1.

[0031] Analysis of the above structure shows that the positions of the calibration lasers 7 on both sides can be determined by the length dimension markings.

[0032] like Figure 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a positioning plate 22 is connected to the rear surface of the two calibration lasers 7, and a positioning groove is opened in the middle of the positioning plate 22.

[0033] Analysis of the above structure shows that when it is necessary to determine the position of the calibration lasers 7 on both sides, the length dimension marking can be directly seen through the positioning groove in the middle of the positioning plate 22, which facilitates positioning.

[0034] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the bottom slide rail 1 has wire grooves on the left and right sides of its lower end. The two side calibration lasers 7, the middle calibration laser 11, the radar position calibration laser 12, and the controller and battery inside the bottom slide rail 1 are all connected through spring wires.

[0035] Analysis of the above structure shows that one end of the spring wire is connected to the controller inside the bottom slide rail 1, and then passes through the wire grooves on the left and right sides of the lower end of the bottom slide rail 1. After passing through the slider, it is connected to the calibration lasers 7 on both sides. The rear ends of the middle calibration laser 11 and the radar position calibration laser 12 are directly connected to the controller inside the bottom slide rail 1 through the spring wire.

[0036] like Figure 1-5As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the lower end of the slot 9 is connected to a protrusion, and the lower rear side of the calibration plate 10 is provided with a bayonet.

[0037] Analysis of the above structure shows that after the rear end of the calibration plate 10 is inserted into the slot 9, the latch on the lower side of the rear end of the calibration plate 10 will fit inside the protrusion at the lower end of the slot 9, reducing the shaking of the calibration plate 10.
