Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. Other embodiments, which can be obtained by one skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1 to 5, the seat surface 1 is supported by the upper left linear piston 5, the upper right linear piston 18 and the arc-shaped piston 3 at three points. The upper part of the arc-shaped piston 3 is placed in the arc-shaped guide rail 2, the arc-shaped guide rail 2 forms an angle of 120 degrees, and the arc-shaped guide rail is not continuous with a connecting point A of the upper left linear piston 5 and the seat surface 1 and is not continuous with a connecting point B of the upper right linear piston 18 and the seat surface 1 so as to maintain the stability of three-point support of the seat surface 1.
The left lower horizontal linear piston guide pipe 13 is fixedly connected with the original moving part of the left linear motor 14 to form the moving part of the left linear motor. The lower left linear piston guide 13 and the upper left linear piston are placed in the left piston guide 6, with the left hydraulic oil 28 filling the middle of the two pistons. The left linear motor 14 is horizontally arranged, receives the instruction of the electronic control unit 27, and controls the motion of the left lower horizontal straight line piston guide pipe 13, the left lower horizontal straight line piston guide pipe 13 transmits the motion to the left hydraulic oil 28, and the left hydraulic oil 28 converts the horizontal linear motion of the left lower horizontal straight line piston guide pipe 13 into the motion of the upper left linear piston 5 in the vertical direction, so that the purpose of controlling the motion of the point A on the seat is achieved, and meanwhile, the vibration and impact energy of the motor and the seat are absorbed. The left hydraulic oil 28 is sealed by a left lower seal ring 30 and a left upper seal ring 31. The lower part of the left sliding base 16 is provided with four foot supports which are arranged in the left front linear guide rail 15 and the left rear linear guide rail 17. The left front linear guide 15 and the left rear linear guide 17 form a semi-enclosed structure, so that the left sliding base 16 can only do linear motion along the guide rails. Because the point A swings up and down to bring the part to move horizontally, the design is used for releasing the degree of freedom of the left part in the horizontal direction. And the base and the parts fixed on the base can only do linear motion along the track without generating redundant uncontrollable freedom.
The right linear motor 21, the right horizontal linear piston guide pipe 20 and the like have the same structure, principle and working mode, so that the aim of controlling the motion of the point B on the seat is fulfilled, and meanwhile, the vibration and impact energy of the motor and the seat are absorbed.
The servomotor 10 is stationary. The driving gear 9 and the original rotating part of the servo motor 10 are fixedly connected into a whole to form the rotating part of the servo motor. The gear rod 11, the driven gear 8 and the arc-shaped piston guide pipe 4 are fixedly connected into a whole, are placed on the gear rod support 12 and can flexibly rotate around the axis of the driven gear 8. The lower part of the arc-shaped piston 3 is placed in the arc-shaped piston guide pipe 4. The servomotor 10, which is positioned vertically, receives commands from an electronic control unit 27, controlling the movement of the driving gear 9. The driving gear 9 transmits the rotational motion of the servo motor 10 to the driven gear 8, and drives the arc piston guide tube 4 and the arc piston 3 to rotate around the central axis of the driven gear 8.

1. the electronic control unit 27 controls the left linear motor 14 and the right linear motor 21 to reset, and controls the arc-shaped piston 3 to reset through the hydraulic oil control box 7, so that the seat surface 1 is in a horizontal position. Then the electronic control unit 27 sends an instruction to the servo motor 10, the servo motor 10 controls the arc-shaped piston 3 to be positioned in the middle of the arc-shaped guide rail 2, and then sends an instruction to the left linear motor 14 and the right linear motor 21, the speeds and the accelerations at A, B are controlled to be equal in magnitude and opposite in direction, so that the seat surface 1 does bumping motion in a vertical plane; or the electronic control unit 27 sends an instruction to the servo motor 10, the servo motor 10 controls the AOC to form an angle alpha, then the hydraulic oil control box 7 controls the hydraulic oil in the front oil pipe 25 and the rear oil pipe 26 to enter and exit, and the point A, B is matched with the movement of the point C, so that the bumping movement of the seat in the vertical plane is realized. The condition that point A, B is satisfied is that point A should be a distance R.sin β.cos α from the horizontal plane at O, and point B should be a distance-R.sin β.cos α from the horizontal plane at O, where β is a negative value when OC is below the horizontal plane at O and a positive value when OC is above the horizontal plane at O.
2. The components are reset as the above 1, then the hydraulic oil control box 7 controls beta to be a constant angle, the electronic control unit sends a command to the servo motor 10 to control the change of alpha, the distance between the control point A of the two linear motors and the horizontal plane at the O position is R.sin beta.cos alpha, and the distance between the control point B and the horizontal plane at the O position is-R.sin beta.cos alpha, thereby realizing the continuous angle rotation looking-up action of people on the seat surface 1 at any direction.
3. The left linear motor 14, the right linear motor 21, the servo motor 10 and the hydraulic oil control box 7 can be controlled in a coordinated mode to realize more movement modes. The relationship still needs to be satisfied that the distance from the point A to the horizontal plane at O is R.sin beta.cos alpha, and the distance from the point B to the horizontal plane at O is-R.sin beta.cos alpha.
As shown in fig. 3: the left linear motor 14 controls the movement of the left lower horizontal linear piston conduit 13 so that the left hydraulic oil 28 converts the horizontal linear movement of the left lower horizontal linear piston conduit 13 into a vertical linear movement of the left upper linear piston 5.
As shown in fig. 4, the hydraulic oil control box 7 controls the movement of the arc-shaped piston 3 through the front oil pipe 25 and the rear oil pipe 26, OC forms an angle β with the horizontal plane at O, and the angle β can be obtained by measuring the volume of the middle hydraulic oil 29.
As shown in fig. 5, the bottom of the left slide base 16 has four supports, which are placed in the left front linear guide 15 and the left rear linear guide 17, and limit the left slide base 16 to move only linearly along the guide.
