[0002] The multi-degree-of-freedom motion control platform is a mechanical system that can simulate multiple degrees of freedom. It is widely used in flight simulators, driving simulators, virtual reality VR and augmented reality AR. With the continuous development of science and technology, the technology of multi-degree-of-freedom motion control platform is also constantly improving.

[0003] The three-degree-of-freedom platform without auxiliary mechanism that appeared earlier, by adding auxiliary T-type connecting rod and linear bearing mechanism with electric push rod equipped with cross bearings at both ends, forms a set of three-degree-of-freedom system that can swing freely. It solves the problem that the bearing capacity of the original three-degree-of-freedom platform is partly on the side of the electric push rod, effectively improves the service life of the electric push rod and extends the maintenance cycle of the electric push rod, and increases the stability of the overall structure. However, the three-degree-of-freedom electric push rod platform structure has problems such as poor structural stability, the electric push rod wears out after a short period of use, causing high platform noise, and even the blockage of the screw rod causing the equipment to fail to operate.

[0004] In response to the above problems, the utility model patent "A multi-automatic motion platform with translation function" with application number 202120519105.3 provides a solution. The platform includes a base plate, on which a first crank drive assembly and a second crank drive assembly are arranged relative to each other at intervals; a first platform frame is arranged at one end of the first crank drive assembly and the second crank drive assembly away from the base plate; a first joint ball is arranged at one end of the first crank drive assembly and the second crank drive assembly away from the base plate, and a first joint bearing is sleeved on the first joint ball, and a fisheye coupling is arranged at the end of the first joint bearing away from the first joint ball, a first fisheye base is arranged on the first platform frame, and the first fisheye base and the fisheye coupling are rotatably connected; a second platform frame is arranged on the first platform frame for relative sliding sliding, and a horizontal drive assembly for driving the second platform frame to slide is arranged on the first platform frame; this structure can improve the stability of the motion platform.

[0029] The linear motion component of the motion control platform in this specific implementation manner can be implemented independently or as a key component, which further limits the motion control platform described in the first specific implementation manner.

[0030] For the linear motion components of the motion control platform under this specific implementation, please refer to Figure 4 and Figure 5 As shown, it includes: a fixed long board 301, a support board frame 302, a rotating shaft 303, a traction disk 304, a power servo motor 305, a traction rope 306, a fixed support frame 307, a first guide rod 308, a second guide rod 309 and a moving seat 310. The fixed long board 301 is fixedly arranged on the upper surface of the rotating table 202, and the two sides of the fixed long board 301 are fixedly connected with the support board frame 302, and the upper end of the support board frame 302 is rotatably connected with the rotating shaft 303, and the traction disk 304 is fixedly connected to the rotating shaft 303. The power servo motor 305 is fixedly installed on the side wall of the support board frame 302, and the output shaft end of the power servo motor 305 is fixedly connected to one end of the rotating shaft 303, and the traction rope 306 is sleeved and connected between the two traction disks 304.

[0031] Through this technical solution, the power servo motor 305 can drive the rotating shaft 303 to rotate, so that the rotation of the rotating shaft 303 can drive the traction disk 304 to rotate, and then the rotation of the traction disk 304 can drive the traction rope 306 to move, thereby realizing the moving function of the traction rope 306.

[0032] Fixed brackets 307 are fixedly provided on both sides of the fixed long board 301, a first guide rod 308 is fixedly connected between the two fixed brackets 307, a second guide rod 309 is fixedly connected between the two fixed brackets 307, the two first guide rods 308 pass through both sides of the moving seat 310 and slide with the moving seat 310, the moving seat 310 is fixedly connected to the upper side of the traction rope 306, and the upper surface of the moving seat 310 is fixedly connected to the moving platform 4.

[0035] Through the technical solution, when the traction disk 304 rotates to drive the traction rope 306 to move, the movement directions of the upper and lower sides of the traction rope 306 are opposite, that is, when the upper side of the traction rope 306 moves forward, the lower side of the traction rope 306 moves reversely, so that when the motion platform 4 moves forward, the balancing slider 501 will also move in the reverse direction, so that according to the different positions of the motion platform 4, the balancing slider 501 can be synchronously moved to the reverse position, which plays a function of automatically adjusting the balancing position. The weight of the motion platform 4 is balanced by the balancing slider 501, so that the overall device is more balanced and stable during operation, and the problem that the center of gravity of the platform itself changes too much due to the movement of heavy objects to different positions is avoided.

[0036] Method 4 The following is a specific implementation of the heavy object bearing assembly of the motion control platform of the present invention.

[0037] The heavy object bearing component of the motion control platform in this specific implementation manner can be implemented independently or as a key component, which further limits the motion control platform described in the first specific implementation manner.

[0038] For the heavy object bearing assembly of the motion control platform under this specific implementation mode, please refer to Figure 6 and Figure 7 As shown, it includes: a weight bearing plate 601, a guide sleeve rod 602, a guide moving rod 603, a support spring 604, a fixed cylinder 605, a movable piston 606, a movable guide rod 607 and a self-locking portion 608, wherein a plurality of guide sleeve rods 602 are provided, and the plurality of guide sleeve rods 602 are fixedly arranged on the upper surface of the motion platform 4, and the guide moving rod 603 is slidably connected in the inner cavity of the guide sleeve rod 602, and the top end of the guide moving rod 603 is fixedly connected to the bottom surface of the weight bearing plate 601, and one end of the support spring 604 is fixedly connected to the upper surface of the motion platform 4, and the other end of the support spring 604 is fixedly connected to the bottom surface of the weight bearing plate 601; For further technical solutions, see Figure 8As shown, the fixed cylinder 605 is fixedly arranged on the upper surface of the moving platform 4, and a movable piston 606 is slidably connected in the inner cavity of the fixed cylinder 605, and one end of a movable guide rod 607 is fixedly connected to the upper surface of the movable piston 606, and the other end of the movable guide rod 607 passes through the upper wall of the inner cavity of the fixed cylinder 605 and extends outside the wall, and the top end of the movable guide rod 607 is fixedly connected to the bottom surface of the weight bearing plate 601, and a conveying hose 609 is fixedly connected to the bottom side of the inner cavity of the fixed cylinder 605.

[0039] Through the present technical solution, when it is necessary to carry heavy objects, the heavy objects to be carried can be placed on the upper surface of the heavy object carrying plate 601. Due to the weight of the heavy object itself, the heavy object carrying plate 601 will be pressed down, causing the heavy object carrying plate 601 to move downward. The downward movement of the heavy object carrying plate 601 can push the support spring 604 to contract, and at the same time, the moving guide rod 607 can be moved downward, and then the moving piston 606 can be pushed to move downward in the inner cavity of the fixed cylinder 605. At the same time, when placing heavy objects of different weights, the contraction amount of the support spring 604 will be different, so that the downward pressing distance of the moving guide rod 607 will be different. The heavier the weight of the heavy object itself, the longer the downward pressing distance of the moving guide rod 607 will be.

[0040] For specific technical solutions, please refer to Fig. 9 As shown, the self-locking part 608 includes: a moving slat 6081, a slot 6082, a guide seat 6083, a fixed shell 6084, a positioning slider 6085, a locking pin 6086, a control handle 6087 and a limit spring 6088. The moving slat 6081 is fixedly arranged on the bottom surface of the heavy object bearing plate 601, and a plurality of slots 6082 are opened on the side of the moving slat 6081. The guide seat 6083 is fixedly arranged on the motion platform 4. The motion platform 4 and the guide seat 6083 are both provided with a slot that matches the moving slat 6081. The side wall of the guide seat 6083 is fixedly connected with the fixed shell 608 4. A positioning slider 6085 is slidably connected in the inner cavity of the fixed shell 6084, one end of a locking pin 6086 is fixedly connected to the side wall of the positioning slider 6085, the other end of the locking pin 6086 extends to the slot 6082, one end of a limiting spring 6088 is fixedly connected to the other side wall of the positioning slider 6085, the other end of the limiting spring 6088 is fixedly connected to the inner cavity side wall of the fixed shell 6084, one end of a control handle 6087 is fixedly connected to one side of the positioning slider 6085, the other end of the control handle 6087 passes through the fixed shell 6084 and extends outside the wall.

[0041] Through the technical solution, when the upper surface of the heavy object bearing plate 601 carries a heavy object, the heavy object bearing plate 601 will be pressed down, and the pressing down of the heavy object bearing plate 601 can push the moving slat 6081 to be pressed down, so that the moving slat 6081 continues to move downward, and the downward movement of the moving slat 6081 will cause the locking pin 6086 to move along the slot 6082. When the moving slat 6081 stops moving downward, the locking pin 6086 will also be inserted into the slot 6082 to lock and fix the moving slat 6081. , thereby locking and fixing the weight bearing plate 601. When the weight on the weight bearing plate 601 is removed, the control handle 6087 can be manually moved to drive the positioning slider 6085 to move, thereby driving the locking pin 6086 to move, so that the locking pin 6086 is separated from the slot 6082. Since the limiting effect of the locking pin 6086 is lost, the elastic action of the support spring 604 pushes the weight bearing plate 601 to move upward, so that the weight bearing plate 601 is reset.

[0042] Method 5 The following is a specific implementation of the weight balance assembly of the motion control platform of the present invention.

[0043] The weight balancing component of the motion control platform in this specific implementation manner can be implemented independently or as a key component to further limit the motion control platform described in the first specific implementation manner.

[0044] The weight balance assembly of the motion control platform under this specific embodiment is shown in Fig.10 As shown, it includes: a counterweight shell 701, a connecting hose 702 and a cylinder 703, wherein the counterweight shell 701 is fixedly arranged on the upper surface of the balancing slider 501, and the cylinder 703 is fixedly arranged on the upper surface of the fixed bottom plate 1, and one end of the connecting hose 702 is fixedly connected to the bottom end of the inner cavity of the cylinder 703, and the other end of the connecting hose 702 extends into the inner cavity of the counterweight shell 701 and is fixedly connected to the counterweight shell 701; A piston 704 is slidably connected in the inner cavity of the cylinder 703 , a weight liquid 705 is filled at the lower side of the inner cavity of the cylinder 703 , and an upper end of the inner cavity of the cylinder 703 is fixedly connected to one end of a delivery hose 609 .

[0045] Through this technical solution, when the heavy object carrying plate 601 carries a heavy object, the weight of the heavy object itself will press down the heavy object carrying plate 601 to move, thereby pushing the moving guide rod 607 to move, and then driving the moving piston 606 to move. Since the moving piston 606 moves downward in the inner cavity of the fixed cylinder 605, the gas in the inner cavity of the fixed cylinder 605 can be output through the delivery hose 609, and then the gas enters the upper side of the inner cavity of the cylinder 703 through the delivery hose 609, so that the increase of gas makes the piston 704 in the inner cavity of the cylinder 703 The weight liquid 705 is pressed down in the cavity, so that the counterweight liquid 705 can be squeezed out and transported to the inner cavity of the counterweight shell 701 through the connecting hose 702. Since the counterweight liquid 705 enters the inner cavity of the counterweight shell 701, the weight of the counterweight shell 701 can be increased, and then the weight of the balance slider 501 can be increased, so as to achieve the function of balancing the weight of the heavy object. From the above description, it can be seen that the heavier the weight carried, the more the weight of the counterweight shell 701 increases, so as to realize the function of automatic balancing weight, avoiding the problem of center of gravity offset caused by carrying different weights.

[0046] The weight liquid 705 is a calcium chloride solution.
