[0055] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other. Example 1

[0057] Figure 1 This is a schematic structural view of the multi-degree-of-freedom adjustable steering wheel provided in this embodiment. Figure 2 For example, a structural decomposition diagram, such as Figure 2As shown, the multi-degree-of-freedom adjustable steering wheel includes a steering wheel body 35, and further includes: a top module 1, connected to the steering wheel body 35, for adjusting the steering force of the steering wheel body 35; an angle adjustment module 2, connected to the top module 1, for adjusting the steering wheel body 35's steering wheel angle; a front-to-rear adjustment module 3, connected to the adjustment module, for adjusting the front-to-rear direction of the steering wheel body 35; and a height adjustment module 4, located below the front-to-rear adjustment module 3, for adjusting the height of the steering wheel body 35.

[0058] The steering force of the steering wheel body 35 is adjusted by the top module 1, the steering wheel body 35 wheel angle is adjusted by the angle adjustment module 2, the front and rear adjustment module 3 adjusts the front and rear direction of the steering wheel body 35, and the height adjustment module 4 adjusts the height of the steering wheel body 35. This allows for multi-degree-of-freedom stepless adjustment of the steering wheel without the need for repeated disassembly and reassembly of the steering wheel body 35. It also enables quick adjustment and verification of the optimal installation position of the steering wheel in the cab of various construction machinery, reducing the waste of manpower, time, and materials.

[0059] In this embodiment, as Figure 3 As shown, the top module 1 includes: a top mounting plate 39, which is connected to the angle adjustment module 2; a torque sensor 34, which is used to detect the torque output by the steering wheel body 35; and a magnetic powder brake 36, which is mounted on the top mounting plate 39 and is used to steplessly adjust the steering force of the steering wheel body 35 according to the torque.

[0060] The magnetic powder brake 36 can be installed below the steering wheel body 35, and the torque sensor 34 can be installed between the magnetic powder brake 36 and the steering wheel body 35. After the initial adjustment and marking, the torque sensor 34 detects the torque output by the steering wheel body 35 and transmits it to the magnetic powder brake 36. The magnetic powder brake 36 then adjusts the steering force of the steering wheel body 35 steplessly according to the torque.

[0061] In this embodiment, as Figure 4As shown, the angle adjustment module 2 includes: an angle mounting plate 27, which is slidably connected to the top mounting plate 39 via an angle slider module 28; an angle sensor 30, used to detect the relative rotation angle between the top module 1 and the front and rear adjustment module 3; a fan-shaped plate 26, fixedly connected to the angle mounting plate 27, the fan-shaped plate 26 having a fan-shaped track along the fan-shaped arc, and transmission teeth being formed within the fan-shaped track; an angle motor 20, which is relatively fixed to the angle mounting plate 27 via a bracket 23; the bracket 23 is connected to the front and rear adjustment module 3; an angle driving gear 24, which is drivenly connected to the output end of the angle motor 20; an angle driven gear 19, which meshes with the angle driving gear 24; the angle driven gear 19 is drivenly connected to angle gears 21 and 25; and the angle gears 21 and 25 mesh with the transmission teeth within the fan-shaped track.

[0062] Angle motor 20 drives angle drive gear 24 to rotate, which in turn drives angle driven gear 19 to rotate. During the rotation of angle driven gear 19, angle gears 21 and 25, which are coaxially arranged, rotate. During the rotation of angle gears 21 and 25, they mesh with the track on the sector plate 26 and move along the sector track on the sector plate 26. At the same time, the end of angle mounting plate 27 away from the steering wheel body 35 can be rotatably connected to the front and rear adjustment module 3 through a pin. This allows angle mounting plate 27 to rotate around the center of the pin during the rotation of angle gears 21 and 25, thereby driving the top mounting plate 39 connected to angle mounting plate 27 to rotate synchronously. In turn, the top mounting plate 39 drives the steering wheel body 35 to rotate, realizing stepless adjustment of the steering wheel angle.

[0063] In this embodiment, as Figure 5 , 6 As shown, the front and rear adjustment module 3 includes: a front and rear mounting plate 22, which is fixedly connected to the bracket 23; a fixed mounting plate 16, which is connected to the height adjustment module 4; the fixed mounting plate 16 is slidably connected to the front and rear mounting plate 22 through a front and rear slide rail 18 and a front and rear slider module 10; and a control mechanism, which is connected between the front and rear mounting plate 22 and the fixed mounting plate 16, for controlling the reciprocating motion of the front and rear mounting plate 22 relative to the fixed mounting plate 16.

[0064] The control mechanism drives the front and rear mounting plates 22 to reciprocate relative to the fixed mounting plate 16, and then drives the angle adjustment module 2, the top module 1, and the steering wheel body 35 to reciprocate back and forth through the bracket 23, so as to realize the stepless adjustment of the steering wheel body 35 in the front and rear directions.

[0065] In this embodiment, as Figure 7 , 8As shown, the height adjustment module 4 includes: a height lead screw 15, which is fixedly connected to the fixed mounting plate 16; a turbine device 6, which is disposed on the base 9 and connected to the height lead screw 15; and a height motor 8, which is disposed on the base 9 and whose output end is connected to the turbine device 6 for transmission. The turbine device 6 is used to receive the rotational force from the output end of the height motor 8 and thereby drive the height lead screw 15 to move up and down.

[0066] The turbine device 6 can adopt an existing worm gear drive. The worm is vertically rotatably connected to the base 9. The height screw 15 is threaded inside the worm and passes through the worm. The turbine is driven by the side of the worm. One end of the turbine is driven by the output end of the height motor 8. The other end of the turbine can also be rotatably connected to a fixed rod. The fixed rod is fixedly connected to the base 9 to ensure the stability of the turbine. The height motor 8 drives the turbine to rotate, and the turbine drives the worm to rotate. During the rotation of the worm, the height screw 15 can move up and down inside the worm, which in turn drives the fixed mounting plate 16 to move up and down. Thus, the fixed mounting plate 16 drives the top module 1, the angle adjustment module 2, the front and rear adjustment module 3 and the steering wheel body 35 to move up and down, so as to realize the stepless adjustment of the steering wheel body 35 in the height direction.

[0067] In this embodiment, as Figure 9 , 10 As shown, the top mounting plate 39 is slidably connected to the angle slider module 28 via the top slide rail 38. A top slide table 37 is fixedly connected to the top mounting plate 39, and a top lead screw 31 is internally threaded onto the top slide table 37. The top lead screw 31 is rotatably connected to the angle mounting plate 27 and is driven by the top driven gear 33 and the top driving gear 32 to the output end of the top motor 29 provided on the angle mounting plate 27.

[0068] The top motor 29 drives the top drive gear 32 to rotate. When the top drive gear 32 rotates, it drives the top driven gear 33 that meshes with it to rotate, which in turn drives the top lead screw 31 to rotate. When the top lead screw 31 rotates, it can drive the front and rear slides 17 to drive the top mounting plate 39 to reciprocate relative to the angle mounting plate 27, thereby adjusting the length of the steering wheel body 35 and the angle adjustment module 2 along the disc angle direction after adjustment by the angle adjustment module 2.

[0069] In this embodiment, as Figure 7 As shown, the control mechanism includes front and rear motors 14, fixed on the fixed mounting plate 16; front and rear slides 17, fixed on the front and rear mounting plates 22; and front and rear lead screws 11, rotatably connected to the fixed mounting plate 16 and passing through the front and rear slides 17 and threadedly connected to the front and rear slides 17; the front and rear lead screws 11 are connected to the output end of the front and rear motors 14 through front and rear driving gears 13 and front and rear driven gears 12.

[0070] The front and rear motors 14 can be connected to the front and rear drive gears 13 to drive them to rotate. The front and rear drive gears 13 can mesh with the front and rear driven gears 12 to drive them to rotate. The front and rear driven gears 12 can be connected to the front and rear lead screws 11 to drive the front and rear lead screws 11 to rotate when rotating. When the front and rear lead screws 11 rotate, they drive the front and rear slides 17 to reciprocate along the front and rear slide rails 18, thereby realizing the reciprocating motion of the front and rear mounting plates 22 relative to the fixed mounting plate 16.

[0071] In this embodiment, as Figure 7 , 8 As shown, both the height lead screw 15 and the turbine device 6 are in four sets.

[0072] By setting the height lead screw 15 and the turbine device 6 into four sets and arranging them evenly above the base 9, a stable supporting force can be provided to the fixed mounting plate 16, and the fixed mounting plate 16 can be driven to move up and down stably.

[0073] In this embodiment, the output end of the height motor 8 is connected to the turbine device 6 via a synchronous belt 7; thus, multiple turbine devices 6 can be driven to operate synchronously when the height motor 8 is working.

[0074] Furthermore, in this embodiment, the device is equipped with a dedicated control unit and a set of control software. Input through the software controls the operation of each motor, thereby achieving automatic adjustment of the steering wheel's degrees of freedom. Additionally, during automatic adjustment of each degree of freedom, each motor and sensor synchronously feeds back the final coordinates to the software, providing a more intuitive reading experience. Each degree of freedom is indicated by a scale, enhancing readability. Furthermore, each motor is capable of both forward and reverse rotation. Example 2

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
