Technical Field
[0001] The invention relates to the field of vehicle identification, and in particular to a laser radar scanning column for vehicle scanning. Background Art
[0002] With the development of society, people's living standards are constantly improving, and cars have become an indispensable part of people's lives. The number of cars is increasing. People often encounter insufficient parking spaces when parking. In order to improve the utilization rate of parking spaces, people have invented parking robots. Before moving vehicles, parking robots usually need to scan vehicles and determine the size and model of vehicles, so as to move the vehicles according to the situation of the vehicles. In order to facilitate parking robots to determine vehicle information, people have invented laser radar scanning columns for vehicle scanning. With the rapid development of science and technology, the types and shapes of vehicles are increasing, and the requirements for laser radar scanning columns for vehicle scanning are also constantly increasing, resulting in the laser radar scanning columns used for vehicle scanning failing to meet people's usage requirements;
[0003] The existing laser radar scanning column for vehicle scanning has certain disadvantages when used. First, the existing laser radar scanning column for vehicle scanning is usually directly installed on the upper end of the parking robot, usually only has the function of rotation, the scanning is relatively local, and the situation of the vehicle cannot be clearly judged. Secondly, the height of the car is different, and the height of the existing laser radar scanning column for vehicle scanning is fixed. Taller vehicles will not be recognized, and the recognition accuracy is not high, which cannot meet people's needs. For this reason, we propose a laser radar scanning column for vehicle scanning. Summary of the invention
[0004] The main purpose of the present invention is to provide a laser radar scanning column for vehicle scanning, which can effectively solve the problems in the background technology.

When the sensing distance is reached, the rotary proximity switch is activated to determine the rotation angle and avoid excessive rotation of the laser scanner. The safety performance is higher, and the position of the bolt can be changed to reset the origin of the laser scanner rotation, which is convenient to adjust.
[0016] Preferably, a lifting proximity switch is fixedly installed on the outer surface of one side of the U-shaped mounting plate away from the limiting turntable near the lower end, and a proximity switch baffle is fixedly installed on the front end outer surface of the main body plate near both ends by bolts.

[0032] By means of the rotating device, the rotating motor 1 is started when in use, and the laser scanner 5 is driven to rotate through the synchronous pulley set 6, so as to adjust the angle of the laser scanner 5, so as to scan the car from different angles, and convert the 2D scanning of the laser scanner 5 into 3D scanning, so as to improve the scanning effect and better identify the vehicle information.
[0033] The lifting device includes two sets of guide rods 8, a lead screw 9 and a lifting motor 2. The lead screw 9 is located between the two sets of guide rods 8. The lifting motor 2 is fixedly mounted on the front end outer surface of the U-shaped mounting plate near the upper end. The output end of the lifting motor 2 is movably connected to the upper end of the lead screw 9.

[0037] Through the provided lifting device, when in use, the lifting motor 2 drives the lead screw 9 to rotate, so that the slider on the lead screw 9 moves, driving the U-shaped mounting plate to move, thereby changing the height of the laser scanner 5, so that the vehicle can be scanned from different heights, the scanning is more comprehensive, the recognition accuracy is higher, and it is convenient for the parking robot to transport the vehicle.
[0038] A rotary proximity switch 3 is fixedly mounted on the upper outer surface of the U-shaped mounting plate near the position of the limit turntable 4 by bolts. A plurality of groups of bolt holes are provided on the outer surface of one side of the limit turntable 4, and bolts are arranged inside the bolt holes.
[0039] When the limit turntable 4 rotates, the distance between the bolt and the rotary proximity switch 3 changes, so that the rotary proximity switch 3 is turned on or off, which makes it easier for people to understand the rotation of the laser scanner 5 and better control the rotation range of the laser scanner 5.
[0040] By setting the rotary proximity switch 3, the limit turntable 4 rotates synchronously when the laser scanner 5 rotates. When rotating, the bolt on the limit turntable 4 approaches the rotary proximity switch 3. When the sensing distance is reached, the rotary proximity switch 3 is activated to determine the rotation angle, and to avoid excessive rotation of the laser scanner 5.

The transmission belt is movably mounted on the outer surfaces of the small synchronous wheel and the transmission wheel. The output end of the rotating motor 1 is movably connected to the small synchronous wheel. A transmission shaft is arranged in the middle position of the outer surface of the transmission wheel. One end of the transmission shaft away from the transmission wheel passes through the U-shaped mounting plate and is movably connected to one end of the laser scanner 5 away from the limiting turntable 4.
[0045] It should be noted that the present invention is a laser radar scanning column for vehicle scanning. When in use, the main body plate 10 is installed on the parking robot by bolts. When in use, after the parking robot is in place, the lifting motor 2 and the rotating motor 1 are started at the same time, the rotating motor 1 rotates, and the laser scanner 5 is driven to rotate through the synchronous pulley group 6. When rotating, the laser scanner 5 scans the vehicle information. The lifting motor 2 determines that the lead screw 9 rotates, and the lead screw 9 converts the rotational motion into the main line motion, thereby driving the slider to move, driving the U-shaped mounting plate to move up and down, thereby driving the laser scanner 5 to move up and down. The lifting motor 2 and the rotating motor 1 are started at the same time as the laser scanner 5, and the laser scanner 5 itself can also rotate, so as to scan the vehicle from different angles and read the vehicle information;
[0046] Through the provided rotating device, the rotating motor 1 is started when in use, and the laser scanner 5 is driven to rotate through the synchronous pulley set 6, so as to adjust the angle of the laser scanner 5, so as to scan the car from different angles, and convert the 2D scanning of the laser scanner 5 into 3D scanning, so as to improve the scanning effect and better identify the vehicle information;
[0047] Through the provided lifting device, when in use, the lifting motor 2 drives the lead screw 9 to rotate, so that the slider on the lead screw 9 moves, driving the U-shaped mounting plate to move, thereby changing the height of the laser scanner 5, so that the vehicle can be scanned from different heights, the scanning is more comprehensive, the recognition accuracy is higher, and it is convenient for the parking robot to carry the vehicle;
[0048] By setting the rotary proximity switch 3, the limit turntable 4 rotates synchronously when the laser scanner 5 rotates. When the limit turntable 4 rotates, the bolt on the limit turntable 4 approaches the rotary proximity switch 3. When the sensing distance is reached, the rotary proximity switch 3 is activated to determine the rotation angle, and the laser scanner 5 can be prevented from rotating excessively, with higher safety performance. In addition, the position of the bolt can be changed to reset the origin of the laser scanner 5 rotation, and the adjustment is more convenient.
[0049] By setting the lifting proximity switch 7 and the proximity switch baffle 11, after the lifting device is started, the lifting proximity switch 7 moves synchronously with the U-shaped mounting plate. When the lifting proximity switch 7 passes the proximity switch baffle 11, the height of the laser scanner 5 can be judged to avoid excessive movement of the laser scanner 5. Moreover, people can replace the proximity switch baffles 11 of different specifications to change the lifting origin of the laser scanner 5. It is convenient to use, and the entire laser radar scanning column for vehicle scanning is easy to operate, and the use effect is better than the traditional method, which meets people's use requirements and is more practical.
