Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted servo turntable technology, and in particular to a high-precision fine-tuning pointing device. Background Technology

[0002] With the popularization of artificial intelligence, high-precision steering devices have been introduced into the field of autonomous driving. By installing a dynamically changing steering device on the roof of the car, it is easier for the car to determine its orientation more stably. Most existing car steering devices use a rotating shaft to adjust the direction, which has low adjustment accuracy and cannot achieve fine-tuning of the car's steering. This invention uses a magnetic base to change the height of the adjustment base to change the steering direction, which can greatly improve the adjustment accuracy of vehicle steering. Summary of the Invention

[0003] The purpose of this invention is to provide a pointing device that utilizes the cooperation of multiple magnetic bases and adjustment bases to achieve automatic adjustment of the pointing direction. By adjusting the screw, the rotation of the screw causes a slight change in the height of the magnetic base, which significantly improves the accuracy.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows: a high-precision fine-tuning pointing device, including a pointing adjustment mechanism, the pointing adjustment mechanism including a mounting base plate, the mounting base plate being fixedly installed above the vehicle, a protective box being fixedly installed on the mounting base plate, a first gear rod, a second gear rod, a third gear rod, and a fourth gear rod being rotatably installed inside the protective box, a first magnetic seat being slidably installed on the first gear rod, a second magnetic seat being slidably installed on the second gear rod, a third magnetic seat being slidably installed on the third gear rod, and a fourth magnetic seat being slidably installed on the fourth gear rod, the outer sides of the first, second, third, and fourth magnetic seats are all provided with threads, the first, second, third, and fourth magnetic seats are all threadedly engaged with the protective box, and the upper surfaces of the first, second, third, and fourth magnetic seats are all spherical, and... It is ferromagnetic, and an adjusting seat is installed on the first, second, third, and fourth magnetic suction seats. Four arc grooves are provided below the adjusting seats. The first, second, third, and fourth magnetic suction seats slide in the grooves below the adjusting seats. When the adjusting seats are in the horizontal position, the counterweight iron inside the adjusting seats is directly above the first, second, third, and fourth magnetic suction seats, and is used to connect the first, second, third, and fourth magnetic suction seats. The adjusting seats are magnetically connected to the first, second, third, and fourth magnetic suction seats. A steering seat is fixedly installed on the adjusting seats, and an infrared emitter is fixedly installed on the steering seat. A reflector and a light sensor are fixedly installed on the protective box. The reflector is arranged at the front of the protective box, and the light sensor is arranged at the rear of the protective box. The reflector can reflect the light from the infrared emitter.

[0005] Furthermore, a cover is fixedly installed at the bottom of the protective box, which protects the structure inside the box.

[0006] Furthermore, a base is fixedly installed below the mounting plate, and four bases are arranged to support the pointing device.

[0007] Furthermore, a lower gear and an upper gear are fixedly installed on the first gear rod. The lower gear is located below the first gear rod, and the upper gear is located above the upper gear. A lifting cylinder is fixedly installed on the protective box. A lifting frame is fixedly installed on the telescopic end of the lifting cylinder. A lower adjusting cylinder is fixedly installed on the lifting frame. A lower adjusting rack is fixedly installed on the telescopic end of the lower adjusting cylinder. An upper adjusting cylinder is fixedly installed on the lifting frame. An upper adjusting rack is fixedly installed on the telescopic end of the upper adjusting cylinder. The lower adjusting cylinder and the lower gear form a gear and rack engagement, and the upper adjusting rack and the upper gear form a gear and rack engagement. When the lower adjusting cylinder is activated, the extension and retraction end of the lower adjusting cylinder moves, causing the lower adjusting rack to move. The lower adjusting rack then drives the lower gear to move. The second, third, and fourth gear rods are all equipped with lower gears. The movement of the lower adjusting rack causes the first and fourth gear rods to rotate in the same direction, and the second and third gear rods to rotate in the same direction, while the first and second gear rods rotate in opposite directions. This controls the first and fourth magnetic suction seats to rise simultaneously while the second and third magnetic suction seats fall, or the first and fourth magnetic suction seats to fall while the second and third magnetic suction seats rise, thus adjusting the forward and backward tilt direction. When adjusting the left and right tilt angles, the tilt angle is not the same as the left and right direction of the vehicle. Rather, it is affected by factors such as the uneven tire pressure on the left and right sides of the vehicle, resulting in one side being higher and the other lower, or the inherent height difference on the left and right sides of the road. The lifting cylinder is activated, which drives the lifting frame to rise and fall. The lifting frame drives both the lower and upper adjusting cylinders to rise. The lower adjusting rack no longer engages with the lower gear, and the upper gear engages with the upper adjusting rack. At this time, the upper adjusting cylinder works, causing the first and second gear rods to rotate in the same direction, the third and fourth gear rods to rotate in the same direction, and the first and fourth gear rods to rotate in opposite directions. This allows the left side to rise or fall simultaneously, while the right side moves in the opposite direction to the left, thus achieving the adjustment of the left and right tilt angles.

[0008] Furthermore, the protective box is equipped with a sliding groove for the lifting frame to slide on the protective box, which facilitates the simultaneous up and down movement of the lower and upper adjusting cylinders.

[0009] Furthermore, a steering motor is mounted on the steering seat, and a steering belt is fixedly mounted on the output shaft of the steering motor. The steering belt includes a pulley, which is rotatably mounted on the steering seat and fixedly connected to the infrared emitter. When the steering motor is started, it drives the steering belt to rotate, which in turn drives the pulley to rotate. The pulley then drives the infrared emitter to rotate, and the rotation of the infrared emitter finely adjusts the left and right tilt angle of the laser emission, facilitating light correction.

[0010] Furthermore, the area of ​​the light-sensing screen is larger than the area of ​​the reflector.

[0011] Furthermore, the cross-section of the slide groove below the adjusting seat is arc-shaped, and the overall shape is grid-shaped, which facilitates the sliding of the first magnetic seat, the second magnetic seat, the third magnetic seat, and the fourth magnetic seat in the groove below the adjusting seat.

[0012] The beneficial effects of this invention compared with the prior art are: (1) This invention utilizes the cooperation of multiple magnetic bases and adjustment bases to realize the automatic adjustment of the pointing direction of the pointing device. Through the adjustment of the screw, the rotation of the screw drives the magnetic base to change slightly, which significantly improves the accuracy; (2) This invention utilizes the cooperation of four gears and two adjustment racks to intelligently adjust the arrangement of the magnetic bases to raise or lower the overall height, which speeds up the adjustment efficiency without affecting the accuracy of the magnetic base.

Detailed Implementation

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example: Figures 1-6The high-precision fine-tuning pointing device shown includes a pointing adjustment mechanism. The pointing adjustment mechanism includes a mounting base plate 1, which is fixedly mounted above the vehicle. A protective box 2 is fixedly mounted on the mounting base plate 1. A first gear rod 12, a second gear rod 13, a third gear rod 14, and a fourth gear rod 15 are rotatably mounted inside the protective box 2. A first magnetic seat 5 is slidably mounted on the first gear rod 12, a second magnetic seat 6 is slidably mounted on the second gear rod 13, a third magnetic seat 7 is slidably mounted on the third gear rod 14, and a fourth magnetic seat 8 is slidably mounted on the fourth gear rod 15. The outer sides of the first magnetic seat 5, second magnetic seat 6, third magnetic seat 7, and fourth magnetic seat 8 are all threaded, forming a threaded engagement with the protective box 2. The upper surfaces of the first magnetic seat 5, second magnetic seat 6, third magnetic seat 7, and fourth magnetic seat 8 are all spherical and ferromagnetic. Adjusting seats 9 are installed on magnetic bases 6, 7, and 8. Four arc-shaped grooves are provided below the adjusting seats 9. The first magnetic base 5, second magnetic base 6, third magnetic base 7, and fourth magnetic base 8 slide within these grooves. When the adjusting seat 9 is in a horizontal position, the counterweight inside the adjusting seat 9 is positioned directly above the first magnetic base 5, second magnetic base 6, third magnetic base 7, and fourth magnetic base 8, serving to connect the first magnetic base 5, second magnetic base 6, third magnetic base 7, and fourth magnetic base 8. The magnetic base 7, the fourth magnetic base 8, and the adjusting base 9 are magnetically connected to the first magnetic base 5, the second magnetic base 6, the third magnetic base 7, and the fourth magnetic base 8. A steering base 10 is fixedly installed on the adjusting base 9, and an infrared emitter 11 is fixedly installed on the steering base 10. A reflector 27 and a light sensor 28 are fixedly installed on the protective box 2. The reflector 27 is arranged in front of the protective box 2, and the light sensor 28 is arranged in rear of the protective box 2. The reflector 27 can reflect the light from the infrared emitter 11. A fine-tuning pointing device is positioned above the vehicle for automatic navigation guidance. Infrared transmitter 11 emits infrared light, which, when reflected by reflector 27, is received by photosensitive screen 28. The photosensitive screen 28 determines the angle of offset between the plane of the adjusting seat 9 and the plane of the protective box 2 based on the sensed light signal, thus determining the directional offset. Reflection by reflector 27 increases the optical path and widens the angle, facilitating signal reception by the photosensitive screen 28. Based on the current vehicle direction of movement, the angle of the adjusting seat 9 needs to be automatically adjusted. Rotating the first gear rod 12, the second gear rod 13, the third gear rod 14, and the fourth gear rod 15 can drive the first magnetic base 5, the second magnetic base 6, the third magnetic base 7, and the fourth magnetic base 8 to rotate. While the first magnetic base 5 rotates, it will rise or fall by a certain angle. The first magnetic base 5, the second magnetic base 6, the third magnetic base 7, and the fourth magnetic base 8 adjust their heights simultaneously, thereby automatically adjusting the rotation angle of the adjusting seat 9. At the same time, the first magnetic base 5, the second magnetic base 6, the third magnetic base 7, and the fourth magnetic base 8 will also slide in the groove under the adjusting seat 9.The pitch between the first magnetic base 5 and the protective box 2 is very small, and the height of the first magnetic base 5 changes very little with each rotation, thus achieving high-precision adjustment of the pointing position.

[0022] A cover 3 is fixedly installed at the bottom of the protective box 2, and the cover 3 protects the structure inside the protective box 2.

[0023] A base 4 is fixedly installed below the mounting base 1. Four bases 4 are arranged to support the pointing device.

[0024] A lower gear 16 and an upper gear 17 are fixedly installed on the first gear rod 12. The lower gear 16 is located below the first gear rod 12, and the upper gear 17 is located above the first gear rod 12. A lifting cylinder 18 is fixedly installed on the protective box 2. A lifting frame 19 is fixedly installed on the telescopic end of the lifting cylinder 18. A lower adjusting cylinder 20 is fixedly installed on the lifting frame 19. A lower adjusting rack 21 is fixedly installed on the telescopic end of the lower adjusting cylinder 20. An upper adjusting cylinder 22 is fixedly installed on the lifting frame 19. An upper adjusting rack 23 is fixedly installed on the telescopic end of the upper adjusting cylinder 22. The lower adjusting cylinder 20 and the lower gear 16 form a gear and rack engagement, and the upper adjusting rack 23 and the upper gear 17 form a gear and rack engagement. When the lower adjusting cylinder 20 is activated, the extension and retraction end of the lower adjusting cylinder 20 moves, causing the lower adjusting rack 21 to move. The lower adjusting rack 21 then moves the lower gear 16. The second gear rod 13, the third gear rod 14, and the fourth gear rod 15 are all equipped with lower gears 16. The movement of the lower adjusting rack 21 causes the first gear rod 12 and the fourth gear rod 15 to rotate in the same direction, and the second gear rod 13 and the third gear rod 14 to rotate in the same direction. However, the rotation directions of the first gear rod 12 and the second gear rod 13 are opposite, thereby controlling the first magnetic base 5 and the fourth magnetic base 8 to rise simultaneously while the second magnetic base 6 and the third magnetic base 7 fall, or the first magnetic base 5 and the fourth magnetic base 8 to fall while the second magnetic base 6 and the third magnetic base 7 rise, thus adjusting the forward and backward tilt direction. When it is necessary to adjust the left and right tilt angles, the left and right tilt angles are not the left and right directions of the vehicle, but rather the influence of different tire pressures on the left and right sides of the vehicle, resulting in one side being higher and the other lower, or the height difference between the left and right sides of the road surface itself. The lifting cylinder 18 is activated, which drives the lifting frame 19 to rise and fall. The lifting frame 19 drives the lower adjusting cylinder 20 and the upper adjusting cylinder 22 to rise. The lower adjusting rack 21 no longer engages with the lower gear 16, and the upper gear 17 engages with the upper adjusting rack 23. At this time, the upper adjusting cylinder 22 works, which drives the first gear rod 12 and the second gear rod 13 to rotate in the same direction, the third gear rod 14 and the fourth gear rod 15 to rotate in the same direction, and the first gear rod 12 and the fourth gear rod 15 to rotate in opposite directions. Thus, the left side is adjusted to rise or fall simultaneously, while the right side is exactly opposite to the left side, thereby achieving the adjustment of the left and right tilt angles.

[0025] The protective box 2 is provided with a sliding groove for the lifting frame 19 to slide on the protective box 2, so as to facilitate the simultaneous up and down movement of the lower adjusting cylinder 20 and the upper adjusting cylinder 22.

[0026] A steering motor 24 is mounted on the steering seat 10. A steering belt 25 is fixedly mounted on the output shaft of the steering motor 24. The steering belt 25 includes a pulley 26, which is rotatably mounted on the steering seat 10 and is fixedly connected to the infrared emitter 11. When the steering motor 24 is started, it drives the steering belt 25 to rotate, which in turn drives the pulley 26 to rotate. The pulley 26 then drives the infrared emitter 11 to rotate, allowing the infrared emitter 11 to finely adjust the left and right tilt angle of the laser emission for light correction.

[0027] The area of ​​the light-sensitive screen 28 is larger than the area of ​​the reflector 27.

[0028] The cross-section of the slide groove below the adjusting seat 9 is arc-shaped, and the overall shape is grid-shaped, which facilitates the sliding of the first magnetic seat 5, the second magnetic seat 6, the third magnetic seat 7, and the fourth magnetic seat 8 in the groove below the adjusting seat 9.
