[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] During driving, due to the design of the vehicle body, there are always some blind spots in the visual range that the exterior rearview mirror can provide to the driver, which makes it impossible to see the vehicle in the blind spot before changing lanes. If there is a vehicle that is overtaking in the blind spot, a collision accident will occur when changing lanes. In heavy rain, fog, and dim light at night, it is even more difficult to see the vehicle behind, and changing lanes at this time faces greater danger. The development and application of corner radar is to solve the problem of blind spots in rearview mirrors.

[0004] At present, the commonly used method of fixing the corner cone is to fix the corner cone on a gantry or a manipulator for corner radar calibration. Fixing it on a gantry generally shares the gantry with other calibration targets. This method requires that the calibration distances of the two can be compatible. Fixing it on a manipulator has good compatibility, but the operation is difficult, the efficiency is low, and the price is relatively expensive, which increases the cost. Summary of the invention

At the same time, the corner cone rod can be adjusted in the horizontal position by manual adjustment, which achieves the purpose of high compatibility and flexible adjustment. The overall operation is simple, efficient, and effectively reduces costs.

[0026] At present, the commonly used method of fixing the corner cone is to fix the corner cone on a gantry or a manipulator for corner radar calibration. Fixing it on a gantry generally shares the gantry with other calibration targets. This method requires that the calibration distances of the two can be compatible. Fixing it on a manipulator has good compatibility, but the operation is difficult, the efficiency is low, and the price is relatively expensive, which increases the cost.

[0029] The servo motor 8, linear guide 4, connecting rod 6, angle cone rod 7, rotating cylinder 12 and spring blocker 13 and other components are used to realize the position adjustment of the angle cone in the X-axis, Y-axis and Z-axis directions and the rotation of the angle cone, so as to adapt to the angle radars at different positions; that is, the bottom rotating cylinder 12 is used to drive the angle cone to move to the working position, and the servo motor 8 is used to drive the entire angle cone rod 7 to move up and down to adapt to the different height positions of the angle radar. At the same time, the angle cone rod 7 can be adjusted in the horizontal position by manual adjustment, so as to achieve the purpose of high compatibility and flexible adjustment. The overall operation is simple, the work efficiency is high, and the cost is effectively reduced.

[0030] The servo motor 8 is installed on the linear guide shield 1, and the output end of the servo motor 8 is connected to the direct guide rail. The servo motor 8 drives the connecting rod 6 to move along the linear guide rail 4. The servo motor 8 provides power to the linear guide rail 4, so that the linear guide rail 4 drives the connecting rod 6 to move, so as to adjust the position of the cone in the Z-axis direction. The linear shield plays a protective role, protects the internal linear guide rail 4, and is used to install the servo motor 8.

[0031] The linear guide 4 is an existing structure. The linear guide 4 is a device used to support and guide the moving parts to make reciprocating linear motion in a given direction. The load is usually transmitted by balls. It consists of a slider, a guide rail, and a ball. The slider slides on the guide rail, and the ball rolls between the slider and the guide rail to reduce friction resistance and achieve high-precision linear motion.

[0032] The connecting rod 6 is detachably connected to the linear guide rail 4 through the first fixing lock 5, and the pyramid rod 7 is detachably connected to the connecting rod 6 through the second fixing lock 5. The pyramid rod 7 is detachably connected to the first fixing lock 5 through a screw, and the connecting rod 6 is detachably connected to the second fixing lock 5 through a screw.

[0033] By manually adjusting the position of the screw on the pyramid rod 7, the position of the pyramid rod 7 in the X-axis direction is adjusted; by manually adjusting the position of the screw on the connecting rod 6, the position of the connecting rod 6 is adjusted, and then the position of the pyramid rod 7 in the Y-axis direction is adjusted. The first fixed lock 3 and the second fixed lock 5 are used to lock the position of the connecting rod 6 and the pyramid rod 7 after adjustment to ensure the firmness of the connection.

[0034] The linear guide shield 1 is movably connected to the base shield 11, and the linear guide shield 1 is driven to rotate by the rotary cylinder 12.

[0035] The spring stopper 13 is an existing structure. The spring stopper 13 is a product specially designed for the automated conveying system. Its main function is to realize the transportation and pause control of the work fixture and the product through the action of the spring. This blocker can not only effectively control the movement of the fixture, but also reduce its impact on the blocking cylinder through the buffer device.

[0036] A cable tube 9 is provided at one end of the linear guide shield 1, and cables are provided in the cable tube 9. A cable tube fixing ring 10 is provided at the lower end of the cable tube 9, and the cable tube fixing ring 10 is located at the upper end of the base shield 11. The cable tube 9 is connected to the base shield 11 through the cable tube fixing ring 10.

[0038] Embodiment 2:

[0039] A method for using an angle radar calibration device comprises the following steps:

[0040] The linear guide shield 1 is driven to rotate by the rotating cylinder 12, and a spring stopper 13 is provided at one end of the rotating cylinder 12. The spring stopper 13 limits the rotation angle of the linear guide shield 1, thereby realizing that the pyramid mechanism rotates to a 90° position and stops; then the servo motor 8 drives the linear guide rail 4, the linear guide rail 4 drives the connecting rod 6 to move, and the connecting rod 6 drives the pyramid rod 7 to move, thereby realizing the position adjustment of the pyramid rod 7 in the Z-axis direction;

[0041] Then, by manually adjusting the fixing screws of the pyramid rod 7, the front and rear positions of the pyramid rod 7 can be adjusted, so that the position of the pyramid rod 7 in the X-axis direction can be adjusted; by manually adjusting the fixing screws on the first fixed lock buckle 3, the left and right positions of the pyramid rod 7 can be adjusted, so that the position of the pyramid rod 7 in the Y-axis direction can be adjusted; the first fixed lock buckle 3 and the second fixed lock buckle 5 are used to adjust the position of the rear locking connecting rod 6 and the pyramid rod 7 to ensure the firmness of the connection.

[0042] The purpose of setting the rotating cylinder is to drive the corner cone to extend when in use to calibrate the corner radar; after the calibration, it rotates to its original position to make room for the vehicle to drive out. During calibration, the corner cone is required to be directly opposite the corner radar position, so the angle of the rotating cylinder is limited to 90°. Finally, the position adjustment of the corner cone at the end of the corner cone rod 7 in the X-axis, Y-axis and Z-axis directions and the rotation of the corner cone are achieved, thereby adapting to corner radars in different positions.

[0043] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
