[0032] Example

[0033] like Figure 1-5As shown, a non-avoidance mechanical parking device includes a column 1, on which a lifting vehicle loading plate 2 and a lifting drive device 3 for driving the lifting vehicle loading plate 2 to slide up and down are arranged, and a non-avoidance vehicle loading plate 4 is movably arranged directly below the lifting vehicle loading plate 2. In this embodiment, there are two columns 1, and the two columns 1 are symmetrically arranged on the left and right. The left and right sides of the lifting vehicle loading plate 2 are slidably connected to the two columns 1 through slides respectively. The lifting drive device 3 includes a lifting motor and a chain. The lifting motor is arranged on the upper part of the column 1, and drives the lifting vehicle loading plate 2 to rise or fall through the chain. The chain is fixedly connected to the slide on one side of the lifting vehicle loading plate 2. The lifting drive device 3 is a prior art and is widely used in non-avoidance parking equipment. This specification will not elaborate on it in detail.

[0034] The non-avoiding vehicle loading plate 4 includes a vehicle plate body 5, a left universal wheel 6, a right universal wheel 7, a left driving wheel 8, a right driving wheel 9, a differential 10 and a translation drive motor 11. The left universal wheel 6 and the right universal wheel 7 are both located at the front of the vehicle plate body 5 and are symmetrically arranged. The left driving wheel 8 and the right driving wheel 9 are both located at the rear of the vehicle plate body 5 and are symmetrically arranged. The differential 10 is arranged on the bottom surface of the vehicle plate body 5 and is located between the left driving wheel 8 and the right driving wheel 9. The two output shafts of the differential 10 are connected to the left driving wheel 8 and the right driving wheel 9 respectively. The translation drive motor 11 is arranged on the bottom surface of the vehicle plate body 5, and its output shaft is connected to the input shaft of the differential 10. In addition, a plurality of anti-skid grooves 25 are provided on the top surface of the vehicle plate body 5, and the length direction of the anti-skid grooves 25 is arranged parallel to the width direction of the vehicle plate body 5. The vehicle plate body 5 is provided with limit plates 26 on the left side, right side and rear side of its top surface.

[0035] The non-avoidance mechanical parking equipment also includes a control system, which includes a control box 13, a wireless signal receiver 15, a remote controller 16, a laser transmitter 14, a laser receiver 17, a signal converter 18, an angle sensor 19 and a distance measuring device 20. The wireless signal receiver 15 is arranged on the front of the column 1, specifically, the wireless signal receiver 15 is located at the upper part of the column 1. The laser transmitter 14 is arranged behind the vehicle plate body 5 and outside the horizontal projection of the lifting vehicle plate 2. Specifically, the laser transmitter 14 is mounted on a fixed bracket 24, and an assembly plate is arranged at the bottom of the fixed bracket. At least two bolt holes are opened on the assembly plate, and when installed, it is fixed to the ground by bolts. The laser receiver 17 is located on the rear side of the vehicle plate body 5, and the laser receiver 17 is a grating ruler or a plurality of laser receiving heads arranged side by side. In this embodiment, the laser receiver 17 is a grating ruler. The grating ruler is also called a grating ruler displacement sensor, which is a measurement feedback device that works based on the optical principle of a grating. Grating rulers are often used in closed-loop servo systems of CNC machine tools. They can be used to detect linear displacement or angular displacement. The measured output signal is a digital pulse, which has the characteristics of large detection range, high detection accuracy and fast response speed. The middle of the laser receiver 17 is the zero point, which is set relative to the laser emitted by the laser transmitter 14. The signal converter 18, the angle sensor 19 and the distance measuring device 20 are all arranged on the vehicle plate body 5, and the signal converter 18 is connected to the laser receiver 17. The control box 13 is independently arranged, and a PLC controller 21 and a frequency converter 12 are arranged in the control box 13. The signal converter 18, the angle sensor 19, the distance measuring device 20, the wireless signal receiver 15, the frequency converter 12 and the lifting motor of the lifting drive device 3 are all connected to the PLC controller 21. The frequency converter 12 is connected to the translation drive motor 11.

[0036] Among them, the angle sensor 19 is a gyroscope or an encoder, and the distance measuring device 20 includes a magnetic block 22 arranged on the left driving wheel 8 or the right driving wheel 9 and a magnetic induction sensor 23 arranged on the vehicle board body 5. When the magnetic block 22 rotates to a certain point with the left driving wheel 8 or the right driving wheel 9, it is just arranged opposite to the magnetic induction sensor 23 and is sensed by the magnetic induction sensor 23; the magnetic induction sensor 23 is connected to the PLC controller 21. Since the outer diameter of the left driving wheel 8 or the right driving wheel 9 is fixed, the magnetic block 22 of the distance measuring device 20 is sensed once every rotation by the magnetic induction sensor 23, that is, during the movement of the vehicle board body 5, the number of rotations of the left driving wheel 8 or the right driving wheel 9 can be measured, and the measured number of rotations multiplied by the outer diameter of the driving wheel can obtain the moving distance. In this embodiment, the angle sensor 19 is a gyroscope, and the angle sensor 19 is located in the middle of the bottom surface of the vehicle board body 5, and the magnetic block 22 of the distance measuring device 20 is arranged on the left driving wheel 8.

[0037] The wireless signal receiver 15 is used to receive the first instruction and the second instruction sent by the remote controller 16. When the wireless signal receiver 15 receives the first instruction, it sends the first instruction to the PLC controller 21. After receiving the first instruction, the PLC controller 21 controls the translation drive motor 11 to rotate through the frequency converter 12. The translation drive motor 11 drives the left drive wheel 8 and the right drive wheel 9 to rotate at the same speed through the differential 10, and drives the vehicle plate body 5 to move forward; when the vehicle plate body 5 moves forward a set distance, the PLC controller 21 adjusts the rotation speed of the translation drive motor 11 through the frequency converter 12, and the translation drive motor 11 adjusts the wheel speed difference between the left drive wheel 8 and the right drive wheel 9 through the differential 10, and drives the vehicle plate body 5 to rotate. When the vehicle plate body 5 rotates 90 degrees, the PLC controller 21 adjusts the rotation speed of the translation drive motor 11 through the frequency converter 12, and the translation drive motor 11 controls the left drive wheel 8 and the right drive wheel 9 to move at the same speed through the differential 10. When the vehicle plate body 5 moves a set distance, the PLC controller 21 controls the translation drive motor 11 to stop rotating through the frequency converter 12, and controls the lifting drive device 3 to operate, driving the lifting vehicle plate 2 to descend to the ground. When the wireless signal receiver 15 receives the second instruction, the PLC controller 21 controls the lifting drive device 3 to operate, driving the lifting vehicle plate 2 to rise. When the lifting vehicle plate 2 rises to the initial position, the PLC controller 21 controls the non-avoidance vehicle plate 4 to automatically reset to the bottom of the lifting vehicle plate 2 according to the previous route. Specifically: the PLC controller 21 first controls the non-avoidance vehicle plate 4 to retreat a set distance, then controls the non-avoidance vehicle plate 4 to rotate 90 degrees, and finally controls the non-avoidance vehicle plate 4 to retreat a set distance and return to the position directly below the lifting vehicle plate 2.

[0038] Among them, the distance measuring device 20 is used to measure the distance moved by the vehicle plate body 5, the angle sensor 19 is used to measure the angle of rotation of the vehicle plate body 5, and the laser receiver 17 is used to sense whether the laser emitted by the laser transmitter 14 deviates from the zero point during the movement of the vehicle plate body 5 along the straight line direction where the laser is located. If the laser deviates from the zero point, the PLC controller 21 adjusts the rotation speed of the translation drive motor 11 through the frequency converter 12, and the translation drive motor 11 adjusts the wheel speed difference between the left drive wheel 8 and the right drive wheel 9 through the differential 10, corrects the posture of the vehicle plate body 5, so that the laser is relative to the zero point; if the laser is relative to the zero point, the left drive wheel 8 and the right drive wheel 9 keep moving forward at the same speed. When the position of the non-avoiding vehicle plate is offset, the laser point will offset from the zero point to a certain point, and the PLC controller 21 senses the position of the laser through the laser receiver 17, calculates the position of the laser and the zero point, controls the non-avoiding vehicle plate to adjust the wheel speed difference between the left drive wheel 8 and the right drive wheel 9, corrects the posture of the non-avoiding vehicle plate, and makes the laser point return to the zero point position. For example, when the laser spot deviates to the left, the deflection amount is a, and the translation drive motor 11, under the control of the inverter 12, maintains the speed V of the left drive wheel 8 through the regulation of the differential 10. 0 The speed of the right driving wheel 9 is reduced to V 1 , where V 1 =K 1 V 0 +K 2 . V 0 is the initial speed of the right driving wheel 9 before speed regulation, V 1 is the speed of the right driving wheel 9 after speed regulation, K 1 is the speed reduction coefficient, given by V 0 , the distance the laser point moves, and other factors, and is a nonlinear parameter. 2 is the compensation coefficient; K 1 and K 2 is an empirical value, which is obtained by the inventors in the process of research and experiment. Those skilled in the art can also conduct experiments according to the above formula and method to obtain the corresponding empirical value K 1 and K 2 .

[0039] The non-avoidance loading plate 4 of the present invention can automatically go out of the warehouse and return to the warehouse under the control of the control system, thereby realizing the function of the lifting loading plate 2 to store or pick up the car normally. The non-avoidance loading plate 4 automatically goes out of the warehouse and returns to the warehouse by adopting a non-contact positioning method, and does not need to lay mechanical positioning components (such as tracks) on the ground, which effectively reduces the workload and cost of equipment installation and maintenance, and can bring a better user experience.

[0040] The non-avoiding vehicle loading plate 4 of the present invention can dynamically adjust its posture in real time during the movement process to avoid deviation. The dynamic adjustment can also reduce the error in operation and improve the accuracy, while providing more possibilities for the design of such equipment. Among them, the laser emitted by the laser emitter 14 plays a precise guiding role for the non-avoiding vehicle loading plate 4, ensuring that the non-avoiding vehicle loading plate 4 moves along the straight line direction where the laser is located. If the moving direction of the non-avoiding vehicle loading plate 4 deviates from the straight line direction where the laser is located, the control system will control the non-avoiding vehicle loading plate 4 to immediately adjust its posture and return to the set moving direction.

[0041] The present invention also has the advantage of precise control. The angle sensor 19 of the control system is used to measure the rotation angle of the non-avoidance vehicle loading plate 4 to ensure that the non-avoidance vehicle loading plate 4 can accurately rotate 90 degrees. The distance measuring device 20 is used to measure the moving distance of the non-avoidance vehicle loading plate 4, so that the control system can control the non-avoidance vehicle loading plate 4 to perform the next action after the non-avoidance vehicle loading plate 4 moves a set distance, thereby realizing the functions of precise positioning and precise control.

[0042] When the present invention is used, if the user needs to take or place a vehicle on the non-avoidance vehicle loading plate 4, the user can directly drive the vehicle away from the non-avoidance vehicle loading plate 4 or drive the vehicle to the non-avoidance vehicle loading plate 4. If the user needs to take or place a vehicle on the lifting vehicle loading plate 2, the user first sends a first instruction to the wireless signal receiver 15 through the remote controller 16, so that the non-avoidance vehicle loading plate 4 is automatically released from the warehouse, and the lifting vehicle loading plate 2 is lowered to the ground; then, the user drives the vehicle away from the lifting vehicle loading plate 2 or drives the vehicle to the lifting vehicle loading plate 2; finally, the user sends a second instruction to the wireless signal receiver 15 through the remote controller 16, and the lifting vehicle loading plate 2 and the non-avoidance vehicle loading plate 4 are reset in sequence.

[0043] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
