[0002] Excavators are commonly used in infrastructure construction. Operators primarily control the excavator's operation by operating the joystick. However, in harsh or dangerous environments, such as those at high altitudes, cold temperatures, or in areas with toxic gas pollution, it's not practical for operators to operate the excavator's joystick directly from the cab.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0029] The embodiment of the present application provides a control device 100, such as Figure 1 As shown, the control device 100 includes a control valve 10 and an actuation mechanism 20 .

[0030] The control valve 10 includes a valve body 11, which is used to connect to the device to be controlled. The valve body 11 is also provided with a plurality of control buttons 12. Specifically, this embodiment is described by taking the device to be controlled as an excavator as an example. The control valve 10 is specifically a hydraulic control valve, such as Figure 3 As shown, Figure 3 This is a simplified structural cross-sectional view of an embodiment of a control valve 10. The control valve 10 includes a valve body 11, which is provided with a plurality of oil chambers 111. The plurality of oil chambers 111 are connected to the oil circuit system within the excavator through an oil inlet and an oil outlet. A valve core 13 is slidably mounted within at least some of the oil chambers 111. When the valve core 13 slides within the oil chamber 111 and changes position, the amount of oil within the plurality of oil chambers 111 and the direction of the oil circuit flow also change, thereby controlling the boom and arm of the excavator to perform corresponding actions. The specific principle by which the control valve 10 controls the excavator to perform corresponding actions through changes in its internal oil circuit can be referred to the relevant prior art and will not be described in detail here.

[0031] In order to control the movement of the valve core 13, a control button 12 is correspondingly provided above each valve core 13. Specifically, in this embodiment, Figure 2As shown, there are four control buttons 12, evenly spaced along the circumference. They are also slidably mounted on the valve body 11, with one end connected to the valve core 13 and the other end extending out of the top of the valve body 11. Therefore, simply pressing a control button 12 pushes the corresponding valve core 13 to slide, thereby controlling the excavator to perform the corresponding action.

[0032] Of course, a spring 14 is typically provided between the valve core 13 and the control button 12 to provide preload and help return the valve core 13 to its initial position. Furthermore, the excavator's oil system typically includes a pilot oil source valve and a main valve. The control valve 10 is also connected to these two valves to jointly control the excavator's movements. The specific application of the control valve 10 in an excavator can be achieved by referring to relevant existing technologies and will not be discussed in detail here.

[0033] In this application, if Figure 1 As shown, a control mechanism 20 is mounted on the valve body 11 of the control valve 10. The control mechanism 20 is used to press multiple control buttons 12 to cause the controlled device to perform corresponding actions. Specifically, in the embodiment of the present application, the control mechanism 20 mainly includes a rocker 21 and a pressing assembly 22. One end of the rocker 21 is hinged to the valve body 11, and the other end forms a handle 211.

[0034] Specifically, multiple control buttons 12 are located on the top of the valve body 11. Figure 6 One end of the rocker arm 21 is hinged to the top of the valve body 11 through a universal mechanism 23 (such as a cross hinge, a ball joint, a ball cage universal joint, etc.), so that the rocker arm 21 can tilt in different directions relative to the valve body 11. Of course, in other embodiments, if there are only two control buttons 12 arranged opposite to each other on the valve body 11, the rocker arm 21 can be set to tilt only in two directions, that is, the rocker arm 21 can be hinged to the valve body 11 through a common pin shaft. The other end of the rocker arm 21 is suspended and forms a handle 211. The staff can hold the handle 211 to drive the rocker arm 21 to tilt; Figure 3 As shown, the hand-held portion 211 can be spherical, which makes it more convenient for staff to hold and operate.

[0035] like Figure 1 As shown, the pressing assembly 22 is mounted on the rocker 21 and includes at least a plurality of automatic pressing members 221. The control mechanism 20 is further configured to have a manual mode and an automatic mode. In the manual mode, the rocker 21 can drive the pressing assembly 22 to tilt relative to the valve body 11, thereby pressing the control button 12. In the automatic mode, the plurality of automatic pressing members 221 correspond one-to-one with the plurality of control buttons 12, and the automatic pressing members 221 can automatically press the control buttons 12 by moving relative to the rocker 21.

[0036] It is understood that because the pressing assembly 22 is mounted on the rocker 21, when the rocker 21 tilts relative to the valve body 11, the pressing assembly 22 can tilt with the rocker 21, thereby pressing the corresponding control button 12. The pressing assembly 22 includes at least a plurality of automatic pressing members 221. In other words, the pressing assembly 22 can include only the plurality of automatic pressing members 221, or it can include the plurality of automatic pressing members 221 and other components.

[0037] For example, optionally, in one embodiment, the pressing assembly 22 may only include a plurality of automatic pressing members 221, and the plurality of automatic pressing members 221 are all installed on the outer periphery of the rocker 21. The number of the automatic pressing members 221 is set to be the same as the number of the control buttons 12, and the plurality of automatic pressing members 221 correspond one-to-one with the plurality of control buttons 12 in position. In manual mode, the staff member holds the handheld portion 211 of the rocker 21 and drives the rocker 21 to tilt. At this time, some of the automatic pressing members 221 approach and press the corresponding control button 12 as they tilt with the rocker 21. In automatic mode, the rocker 21 is unmanned, and at this time, a portion of the automatic pressing members 221 can be remotely controlled so that a portion of the automatic pressing members 221 moves relative to the rocker 21 and automatically presses the corresponding control button 12, thereby controlling the engineering equipment to perform the corresponding action.

[0038] For example, optionally, in another embodiment, if Figure 4 As shown, the pressing assembly 22 includes a plurality of automatic pressing members 221 and a pressing plate 222. Specifically, as shown in FIG. Figure 5 As shown, the pressure plate 222 is rotatably mounted on the rocker 21 through the bearing 24, and a plurality of through holes 2221 are provided on the pressure plate 222, and the number of through holes 2221 is the same as the number of control buttons 12. A plurality of automatic pressing members 221 are mounted on the pressure plate 222, and the plurality of automatic pressing members 221 correspond to the plurality of through holes 2221 in terms of mounting positions. The pressure plate 222 can rotate between a first position and a second position. When the pressure plate 222 is in the first position, it can be combined with Figure 4 、 Figure 5 and Figure 7 , multiple through holes 2221 correspond to multiple control buttons 12 one by one, at this time the automatic pressing member 221 can pass through the through holes 2221 and press the control button 12. When the pressure plate 222 is in the second position, it can be combined with Figure 5 and Figure 6It is understood that the multiple through holes 2221 and the multiple control buttons 12 are staggered with each other, and the specific staggered angle is not limited. For example, the specific staggered angle can be 15°, 20°, 25°, 30°, 45°, 50°, 60°, etc., that is, the plate body of the pressure plate 222 at this time covers the top of the multiple control buttons 12. When the rocker 21 tilts relative to the valve body 11, the pressure plate 222 will press some of the control buttons 12 as the rocker 21 tilts.

[0039] Therefore, in this embodiment, if the engineering equipment needs to be controlled in manual mode, the pressure plate 222 can be first rotated to the second position, and then the rocker 21 can be held and tilted in a preset direction. At this time, the pressure plate 222 will approach and press the corresponding control button 12 as the rocker 21 tilts, thereby controlling the engineering equipment to perform the corresponding action. If the engineering equipment needs to be controlled in automatic mode, the pressure plate can be first rotated to the first position, so that the multiple automatic pressing members 221, the multiple through holes 2221 and the multiple control buttons 12 correspond one to one. Then, the corresponding automatic pressing member 221 can be remotely controlled to pass through the through hole 2221 and press the control button 12 to control the engineering equipment to perform the corresponding action.

[0040] That is to say, the control device 100 provided in the present application installs the pressing component 22 on the rocker 21 so that the pressing component 22 can press the control button 12 on the valve body 11 as the rocker 21 tilts in manual mode, and the pressing component 22 includes at least a plurality of automatic pressing parts 221 that can automatically press the control button 12 when the rocker 21 is not tilted. This not only has a simple structure and is easy to produce, but also makes the control process in the automatic mode simpler and more convenient. When it is necessary to switch from automatic mode back to manual mode, there is no need to remove the automatic pressing part 221 first, which makes switching between manual mode and automatic mode very convenient.

[0041] It should be noted here that the manual mode and automatic mode of the control mechanism 20 are selected by the staff. For example, when the working environment is relatively normal, the staff can choose to directly manually operate the joystick 21, and the control mechanism 20 is in manual mode at this time; if the working environment is relatively harsh, the staff can choose to control the movement of the automatic pressing part 221 through remote control, preset control algorithms, etc. to press the control button 12.

[0042] In addition, the shape of the automatic pressing member 221 can be a block, plate or other shape, as long as it can stably press the control button 12. The automatic pressing member 221 can be driven automatically by the motor 223 directly, or by the motor 223 in conjunction with other transmission parts (such as gears, racks, screws, etc.). For example, in one embodiment, Figure 2 or Figure 4As shown, the pressing assembly 22 also includes multiple motors 223, and the multiple motors 223 are all servo linear motors 223. The multiple motors 223 are installed on the pressure plate 222, and the multiple motors 223 correspond one-to-one to the multiple through holes 2221. The multiple automatic pressing parts 221 are installed one-to-one on the multiple motors 223. In automatic mode, the motor 223 is used to drive the corresponding automatic pressing part 221 to move relative to the rocker 21. This not only has a simple structure and low cost, but also can accurately control the movement stroke of the automatic pressing part 221.

[0043] Further, such as Figure 2 or Figure 4 As shown, on the basis that multiple automatic pressing parts 221 are respectively driven by multiple motors 223, the pressing assembly 22 also includes a motor 223 mounting seat, the motor 223 mounting seat is annular and is installed on the pressure plate 222, and the motor 223 mounting seat is coaxially arranged with the rocker 21, and multiple motors 223 are installed on the motor 223 mounting seat and are evenly arranged along the circumferential direction of the rocker 21. This not only can better control the relative positions between the multiple motors 223, but also can make the installation of the multiple motors 223 more stable, and avoid the motor 223 itself from shaking and affecting the automatic pressing part 221 pressing the control button 12.

[0044] Optionally, in one embodiment, as Figure 2 As shown, the control device 100 further includes a locking mechanism 30, which is used to limit the tilting of the rocker arm 21 and / or the pressure plate 222 relative to the valve body 11 in the automatic mode. Specifically, in this embodiment, because the pressure plate 222 is mounted on the rocker arm 21 and the automatic pressing member 221 is mounted on the pressure plate 222, in the automatic mode, if the rocker arm 21 or the pressure plate 222 shakes or tilts, for example, if the rocker arm 21 shakes or tilts to a certain extent due to the vibration of the engineering equipment itself, then the rocker arm 21 or the pressure plate 222 will drive the automatic pressing member 221 to tilt or shake to a certain extent, which will cause the movement stroke of the automatic pressing member 221 to be greater than or less than the preset stroke, thereby causing the action performed by the engineering equipment to have a deviation in the movement amplitude, and failing to meet the corresponding action expectations.

[0045] Therefore, in this embodiment, by making the control device 100 also include a locking mechanism 30, the locking mechanism 30 is used to limit the tilting of the rocker arm 21 or the pressure plate 222 relative to the valve body 11 in the automatic mode, so as to avoid the rocker arm 21 or the pressure plate 222 from shaking or tilting in the automatic mode, avoid the movement of the automatic pressing member 221 from being affected, and improve the reliability of the control device 100.

[0046] It should be noted here that there can be multiple specific structural schemes for the locking mechanism 30. For example, optionally, in one embodiment, the locking mechanism 30 can include multiple top blocks, and the multiple top blocks are telescopically mounted on the top of the valve body 11, and the multiple top blocks are all located below the pressure plate 222. In automatic mode, the multiple top blocks extend and hold the pressure plate 222, so that the pressure plate 222 remains in a horizontal plane and cannot tilt relative to the valve body 11. Because the pressure plate 222 is rotatably mounted on the rocker 21 through the bearing 24, the pressure plate 222 that cannot tilt will also make the rocker 21 unable to tilt relative to the valve body 11. When it is necessary to switch to manual mode, the multiple top blocks can be controlled to retract to ensure that the pressure plate 222 can press the control button 12 as the rocker 21 tilts.

[0047] For example, in another embodiment, the locking mechanism 30 may include a fixed claw, which is a rigid part, and one end of the fixed claw is fixed relative to the valve body 11, and the other end simulates the handhold 211 of a human hand grasping the rocker 21. This can also prevent the rocker 21 from tilting relative to the valve body 11 in the automatic mode, thereby preventing the pressure plate 222 from causing the automatic pressing part 221 to tilt.

[0048] For another example, because the pressure plate 222 needs to be rotated to different positions in manual mode and automatic mode, in another embodiment, please combine Figure 2 and Figure 5 The locking mechanism 30 includes a first fixing member 31 and a second fixing member 32. The first fixing member 31 is mounted on the valve body 11. The second fixing member 32 has a first end 321 and a second end 322 opposite to each other. The first end 321 is fixed to the pressure plate 222. Thus, the second fixing member 32 can rotate with the rotation of the pressure plate 222. Figure 2 or Figure 7 As shown, when the pressure plate 222 is in the first position, the second end 322 is fixedly connected to the first fixing member 31, so that the pressure plate 222 can be restricted from tilting relative to the valve body 11, and the pressure plate 222 further restricts the rocker 21 from tilting relative to the valve body 11. Figure 6 As shown, when the pressure plate 222 is in the second position, the second end 322 is suspended in the air, so that the tilting of the rocker 21 and the pressure plate 222 is not affected in the manual mode.

[0049] It can be understood that in this embodiment, the second fixing member 32 of the locking mechanism 30 is fixed on the pressure plate 222 and rotates with the pressure plate 222. In this way, there is no need to separately control the movement of the locking mechanism 30 in order to switch modes, so that the structure of the control device 100 is simple and easy to obtain, and the locking mechanism 30 and the pressure plate 222 can be switched synchronously between manual mode and automatic mode. There is no need to remove the locking mechanism 30 when switching, and switching is very convenient.

[0050] It should be noted here that when the pressure plate 222 is in the first position, there can be multiple ways of fixing the first fixing member 31 and the second fixing member 32. For example, the second end 322 of the second fixing member 32 can be provided with a buckle, and the first fixing member 31 can be provided with a card hole. The second end 322 of the second fixing member 32 is fixed in the card hole of the first fixing member 31 by the buckle, thereby realizing a fixed connection between the first fixing member 31 and the second fixing member 32.

[0051] For another example, bolt holes are respectively provided on the first fixing member 31 and the second fixing member 32. When the pressure plate 222 is in the first position, the first fixing member 31 and the second fixing member 32 are directly fixed by bolts.

[0052] For another example, optionally, in one embodiment, if Figure 2 、 Figure 5 and Figure 7 As shown, the first fixing member 31 is connected to a first nut 33 and a second nut 34 that are spaced apart from each other, and a fitting portion 3221 is formed on the second end 322. The second fitting portion 3221 is a semi-enclosed structure. When the pressure plate 222 is in the first position, the fitting portion 3221 surrounds the outside of the first fixing member 31, and the first nut 33 and the second nut 34 jointly clamp the fitting portion 3221.

[0053] Specifically, the first fixing member 31 is cylindrical, and the mating portion 3221 of the second fixing member 32 extends in an arc, thereby forming a semi-enclosed structure. When it is necessary to switch to automatic mode, the pressure plate 222 can be rotated to the first position, at which point the mating portion 3221 just encircles the outer circumference of the first fixing member 31. Then, one of the nuts is screwed toward the other nut until the two nuts clamp the mating portion 3221. This makes the connection between the first fixing member 31 and the second fixing member 32 more stable and easier to operate. When it is necessary to switch to manual mode, one of the nuts is screwed away from the other nut, loosening the grip on the mating portion 3221, and the pressure plate 222 can be rotated to the second position.

[0054] Optionally, in one embodiment, as Figure 2 As shown, there are multiple first fixing members 31 and multiple second fixing members 32, and the multiple first fixing members 31 and the multiple second fixing members 32 are evenly arranged along the circumferential direction of the rocker 21, as shown in FIG. Figure 2 In the structural scheme shown, there are two first fixing members 31 and two second fixing members 32 respectively, and the two first fixing members 31 and the two second fixing members 32 are symmetrically arranged about the rocker 21. This can not only better limit the tilting of the rocker 21 or the pressure plate 222 in the automatic mode, but also avoid unbalanced force.

[0055] Optionally, in one embodiment, please combine Figure 4and Figure 6 The rocker 21 is provided with a first locking hole 212, the mounting base of the motor 223 is provided with a second locking hole 2241, and the locking mechanism 30 further includes a locking pin 35. When the pressure plate 222 is in the second position, the first locking hole 212 and the second locking hole 2241 are arranged opposite each other, and the locking pin 35 is inserted into the first locking hole 212 and the second locking hole 2241 in the manual mode.

[0056] Specifically, in this embodiment, because the pressure plate 222 is rotatably mounted on the rocker 21 through the bearing 24, the pressure plate 222 may automatically rotate due to the vibrating environment in the manual mode, and then the pressure plate 222 may automatically rotate to the first position in the manual mode, resulting in multiple through holes 2221 corresponding to multiple control buttons 12. At this time, no matter how the pressure plate 222 tilts, the control button 12 cannot be pressed down.

[0057] Therefore, this embodiment sets a first locking hole 212 on the rocker 21 and a second locking hole 2241 on the motor 223 mounting base (the motor 223 mounting base is installed on the pressure plate 222). When the pressure plate 222 rotates to the second position, that is, in manual mode, the first locking hole 212 and the second locking hole 2241 correspond to each other, and the locking pin 35 is inserted into the first locking hole 212 and the second locking hole 2241, so as to prevent the pressure plate 222 from rotating relative to the rocker 21.

[0058] It should be noted here that in order to prevent the locking pin 35 from being lost, the locking pin 35 can be connected to the valve body 11 of the control valve 10 through a rope, or other components (such as the valve body 11, the first fixing member 31, the second fixing member 32, the motor 223 mounting seat, etc.) are provided with a slot for preventing the locking pin 35 from being lost. In this way, the locking pin 35 can be limited to the preset slot in the automatic mode to prevent the locking pin 35 from being lost.

[0059] An embodiment of the present application also provides an engineering equipment (not shown), which can specifically be an excavator or other equipment that needs to switch between manual control and automatic control, and the engineering equipment includes a control device 100.
