[0025] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described below.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1 to 2This utility model provides a manual / automatic integrated lever mechanism, including a mounting frame 1, several levers 2, a rotary drive assembly 3, and a lateral drive assembly 4. The mounting plate serves as the base of the entire mechanism, used to mount the various components. The ends of the levers 2 are respectively connected to the corresponding control ports of the vehicle body multi-way valves, and the multi-way valves are operated by moving the levers 2. Each lever 2 is connected to a connecting rod assembly 5. The mounting frame 1 is provided with a mounting shaft 21, and the connecting rod assembly 5 is rotatably connected to the mounting shaft 21. The rotary drive assembly 3 is used to drive the connecting rod assembly 5 to rotate on the mounting shaft 21, and the rotary drive assembly 3 is slidably mounted on the mounting frame 1. The rotary drive assembly 3 slides along the mounting frame 1 and moves to the position of the corresponding lever 2 to drive the connecting assembly on different levers 2 to rotate, thereby controlling the corresponding lever 2. The lateral drive assembly 4 is mounted on the mounting frame 1 and connected to the rotary drive assembly 3, used to drive the rotary drive assembly 3 to slide. By setting up the transverse drive component 4 and the rotary drive component 3, when it is necessary to switch to automatic control of the joystick 2, automatic control can be achieved simply by using the transverse drive component 4 and the rotary drive component 3; when it is necessary to switch to manual operation, the transverse drive component and the rotary drive component 3 can be reset to their initial positions for manual operation.

[0028] The mounting bracket 1 is provided with a mounting shaft 21. Specifically, the mounting bracket 1 is fixedly provided with a support 24, and the mounting shaft 21 is fixedly provided on the support 24.

[0029] Reference Figure 2 Furthermore, the linkage assembly 5 includes a rotating rod 51 and a connecting rod 52. One end of the connecting rod 52 is provided with a sleeve portion 521. The sleeve portion 521 of each connecting rod 52 is fixedly sleeved on the corresponding control lever 2. The end of the connecting rod 52 away from the sleeve portion 521 is fixedly connected to the rotating rod 51. The rotating rod 51 is rotatably connected to the mounting shaft 21. When the rotating rod 51 rotates clockwise or counterclockwise, it drives the connecting rod 52 to swing up or down accordingly, thereby achieving the purpose of controlling the corresponding control lever 2.

[0030] Furthermore, the rotary drive assembly 3 includes a mounting side plate 31, a rotary motor 32, and a drive lever 33. The mounting side plate 31 is slidably connected to the mounting bracket 1, the rotary motor 32 is fixedly mounted on the mounting side plate 31, and the drive lever 33 is fixedly disposed on the output shaft of the rotary motor 32. The rotary motor 32 is used to drive the drive lever 33 to rotate. The rotation of the drive lever 33 presses the rotating rod 51 upward or downward, thereby causing the rotating rod 51 to rotate on the mounting shaft 21.

[0031] In this embodiment, the rotating rod 51 has a connecting part 511 and a toggle part 512, wherein the connecting part 511 and the toggle part 512 are integrally formed. The connecting part 511 and the toggle part 512 have a rotating hole at the connection point, and the rotating rod 51 is rotatably connected to the mounting shaft 21 through the rotating hole; the connecting part 511 is fixedly connected to the end of the connecting rod 52 away from the sleeve part 521; the toggle part 512 is disposed toward the drive lever 33. When the transverse drive assembly 4 drives the rotary drive assembly 3 to move to the corresponding rotating rod 51, the rotary motor 32 rotates clockwise or counterclockwise, causing the drive lever 33 to rotate clockwise or counterclockwise. During the rotation, the drive lever 33 pushes upward or presses downward against the toggle part 512, driving the rotating rod 51 to rotate counterclockwise or clockwise on the mounting shaft 21, thereby controlling the control lever 2 to achieve the corresponding operation. For example, when it is necessary to control the raising or lowering of the fork arm, the control rotary drive assembly 3 slides to the linkage assembly 5 connected to the corresponding control lever 2. At this time, the rotary motor 32 drives the drive lever 33 to rotate clockwise, and the drive lever 33 pushes the actuating part 512 upward, driving the linkage assembly 5 to rotate, thereby realizing the raising of the fork arm; the rotary motor 32 drives the drive lever 33 to rotate counterclockwise, and the drive lever 33 presses the actuating part 512 downward, driving the linkage assembly 5 to rotate, thereby realizing the lowering of the fork arm.

[0032] Reference Figure 1 and Figure 2 Furthermore, a photoelectric switch 6 is fixedly installed on the mounting side plate 31. The photoelectric switch 6 is used to detect whether the drive lever 33 has reset, so as to reduce the possibility of interference between the drive lever 33 and the linkage assembly 5 during the switch to manual control. Specifically, when the photoelectric switch 6 detects the drive lever 33, the drive lever 33 returns to a position that does not interfere with the linkage assembly 5. At this time, it is only necessary to control the transverse drive assembly 4 to return the rotary drive assembly 3 to the initial position to manually control the joystick 2.

[0033] The transverse drive assembly 4 is used to drive the rotary assembly to slide on the mounting bracket 1. Specifically, the transverse drive assembly 4 includes a drive motor 41, a drive screw 42, and a screw nut 43. The screw nut 43 is threadedly connected to the drive screw 42 and is fixedly mounted on the mounting side plate 31. The drive motor 41 is fixedly connected to the mounting bracket 1, and a screw mounting seat 22 is fixedly connected to the mounting bracket 1. The drive screw 42 is rotatably connected to the screw mounting seat 22, and the input end of the drive screw 42 is connected to the output shaft of the drive motor 41. The drive motor 41 rotates in both directions, causing the drive screw 42 to rotate in both directions, which causes the screw nut 43 to reciprocate along the axial direction of the drive screw 42, thereby driving the rotary drive assembly 3 to slide.

[0034] In this embodiment, a guide rail 23 is fixedly connected to the mounting bracket 1. The guide rail 23 extends axially along the drive screw 42. A slider 311 is fixedly connected to the mounting side plate 31 facing the mounting bracket 1. The slider 311 is slidably connected to the guide rail 23, thereby realizing the sliding connection between the mounting side plate 31 and the mounting bracket 1.

[0035] In this embodiment, the drive screw 42 is set as a ball screw, which has good positioning accuracy and high transmission efficiency, which is beneficial to the positioning of the rotary drive component 3.

[0036] Furthermore, in order to achieve precise positioning of the rotary drive assembly 3, a position sensor can be set on the rotary drive assembly 3. The position sensor is used to detect whether the drive lever 33 has moved accurately to the corresponding rotary rod 51, so as to ensure that the rotary drive assembly 3 can accurately move the required rotary rod 51.

[0037] By setting up the rotation drive assembly 3, the lateral drive assembly 4, and the linkage assembly 5 in coordination, the lever principle is used to rotate and push / pull, which can realize the automatic control of the joystick 2. When it is necessary to switch to manual control, it is only necessary to drive the rotation motor 32 to make the drive lever 33 rotate to the sensing area of ​​the photoelectric switch 6 (i.e., reset), and control the drive motor 41 to make the rotation drive assembly 3 return to the initial position, so as to avoid the drive lever 33 interfering with the linkage assembly 5, that is, switch to manual operation mode.
