Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] Example 1

[0039] This embodiment introduces a noise optimization control system for the actuator of a sanitation vehicle, which includes: a hydraulic control circuit, a pneumatic control circuit, and a controller;

[0040] The hydraulic control circuit includes: a hydraulic oil tank 1, a main directional valve 2, an actuating cylinder 3, and an oil pump 4; the first working port A and the second working port B of the main directional valve 2 are respectively connected to the rodless chamber port and the rod chamber port of the actuating cylinder 3; the oil inlet P of the main directional valve 2 is connected to the oil outlet port of the oil pump 4; and the oil return port T of the main directional valve 2 is connected to the hydraulic oil tank 1.

[0041] The pneumatic control circuit includes: an air source 5, a first reversing valve 6, a second reversing valve 7, a reversing cylinder 8, and a first buffer assembly; the air source 5 is connected to the rodless chamber port and the rod chamber port of the reversing cylinder 8 through a first air passage 9 and a second air passage 10 respectively; the first reversing valve 6 and the second reversing valve 7 are respectively disposed on the first air passage 9 and the second air passage 10; the controller is electrically connected to the control terminals of the first reversing valve 6 and the second reversing valve 7 respectively;

[0042] In operation, the reversing cylinder 8 controls the main reversing valve 2 to switch its working port by extending or retracting its action, thereby controlling the extension or retraction of the actuating cylinder 8; wherein, the first buffer component is provided on the reversing cylinder 8 to reduce the speed at which the reversing cylinder 8 pushes the valve stem inside the main reversing valve 2 to switch its working port.

[0043] It is worth noting that the aforementioned reversing cylinder 8 and the main reversing valve 2 are integrally configured, that is, the piston rod of the reversing cylinder 8 is connected to the valve rod in the main reversing valve 2, thereby enabling the reversing cylinder 8 to push the inner valve rod in the main reversing valve 2 to switch the working port.

[0044] In practical application, when the actuator (i.e., the hydraulic cylinder 3) needs to extend, the controller receives an extension control command from the human-machine interface unit (such as a button, touchscreen, etc.). Then, the controller controls the first directional valve 6 to switch to the working position according to the command, allowing compressed air from the air source 5 to enter the rodless chamber of the directional cylinder 8 through the first air passage 9 (after damping adjustment of the first air passage damper). Simultaneously, the air in the rod chamber of the directional cylinder 8 is discharged to the atmosphere through the second air passage 10 (after damping adjustment of the second air passage damper). Then, the directional cylinder 8 extends due to the increased air pressure in the rodless chamber, and its extended end pushes the inner valve stem of the main directional valve 2 to move, switching the working port of the main directional valve 2 to the first working port A. Finally, the hydraulic oil supplied by the oil pump 4 enters the rodless chamber of the hydraulic cylinder 3 through the oil inlet P of the main directional valve 2, pushing the cylinder to extend.

[0045] When the actuator needs to retract, the controller receives a retraction control command from the human-machine interface unit. Then, the controller controls the second directional valve 7 to switch to the working position according to the corresponding command, allowing compressed air from the air source 5 through the second air passage 10 (after damping adjustment of the second air passage by the first buffer assembly) into the rod chamber of the directional cylinder 8. Simultaneously, the air in the rodless chamber of the directional cylinder 8 is discharged to the atmosphere through the first air passage 9 (after damping adjustment of the first air passage damping). Then, the directional cylinder 8 retracts due to the increased air pressure in the rod chamber, pushing the inner valve stem of the main directional valve 2 to move, switching the working port of the main directional valve 2 to the second working port B. Finally, the hydraulic oil supplied by the oil pump 4 enters the rod chamber of the actuating cylinder 3 through the oil inlet P of the main directional valve 2, pushing the cylinder to retract. Simultaneously, the hydraulic oil in the rodless chamber of the actuating cylinder 3 flows back to the hydraulic oil tank 1 through the oil return port T of the main directional valve 2.

[0046] Example 2

[0047] Referring to Figure 1, based on Embodiment 1, this embodiment also has the following design.

[0048] The noise optimization control system for the sanitation vehicle actuator includes a first buffer component and a second buffer component.

[0049] The first buffer assembly includes a first air path damper 11 and a second air path damper 12. The first air path damper 11 is installed in the rodless chamber air port of the reversing cylinder 8, and the second air path damper 12 is installed in the rod chamber air port of the reversing cylinder 8.

[0050] Specifically, when the reversing cylinder 8 needs to extend (i.e., the rodless chamber is inflated), the first air path damper 11 restricts the rapid flow of air, making the extension of the reversing cylinder 8 smoother and slower. At the same time, the second air path damper 12 also restricts the slow discharge of air from the rod chamber of the reversing cylinder 8 to the atmosphere. When the reversing cylinder 8 needs to retract (i.e., the rod chamber is inflated), the second air path damper 12 also restricts the rapid flow of air, ensuring that the retraction action is also smooth and slow. At the same time, the first air path damper 11 also restricts the slow discharge of air from the rodless chamber of the reversing cylinder 8 to the atmosphere.

[0051] The second buffer assembly includes a third air path damper 13 and a fourth air path damper 14. The third air path damper 13 is installed at the first exhaust port corresponding to the first reversing valve 6, and the fourth air path damper 14 is installed at the second exhaust port corresponding to the second reversing valve 7.

[0052] In practical applications, the first and second buffer components, when used in combination, effectively reduce the impact noise of the sanitation vehicle's actuator during operation, as detailed below:

[0053] The actuator extension process: Based on the actuator extension control command output by the human-machine interface unit, the controller controls the first directional valve 6 to switch to the working position (i.e., the electromagnet YV1 of the first directional valve 6 is energized). This allows compressed air to enter the rodless chamber of the directional cylinder 8 from the working position of the first directional valve 6 via the first air path damper 11. Simultaneously, the air in the rod chamber of the directional cylinder 8 is discharged to the atmosphere via the second air path damper 12 and the fourth air path damper 14. Then, driven by the gas, the directional cylinder 8 moves the inner valve stem of the main directional valve 2 until it switches to the first working port A. The actuating cylinder 3 then extends, meaning the corresponding actuator completes the extension action.

[0054] Actuator retraction process: Based on the actuator retraction control command output by the human-machine interface unit, the controller controls the second directional valve 7 to switch to the working position (i.e., the electromagnet YV2 of the second directional valve 7 is energized). This allows compressed air to enter the rod chamber of the directional cylinder 8 from the working position of the second directional valve 7 via the second air path damper 12. Simultaneously, the air in the rodless chamber of the directional cylinder 8 is discharged to the atmosphere via the first air path damper 11 and the third air path damper 13. Then, driven by the gas, the directional cylinder 8 moves the inner valve stem of the main directional valve 2 until it switches to the second working port B. The actuating cylinder 3 then retracts, meaning the corresponding actuator completes its retraction action.

[0055] In this embodiment, the first reversing valve 6 and the second reversing valve 7 are two-position, two-way solenoid valves. The first reversing valve 6 and the second reversing valve 7 can be integrated into the electrically controlled multi-way valve or exist independently. Furthermore, the first reversing valve 6 and the second reversing valve 7 can be components or exist independently according to layout requirements.

[0056] This embodiment, through the combined action of the first and second buffer components, enables the system to significantly reduce noise generated during action switching and air pressure changes, while also reducing impact and wear on the system. This not only improves the stability and reliability of the system but also makes the sanitation vehicle quieter and more environmentally friendly when performing its tasks.

[0057] Furthermore, the orifice diameters of the first air path damper 11, the second air path damper 12, the third air path damper 13, and the fourth air path damper 14 can be adaptively determined according to the control requirements of the actuating cylinder 3.

[0058] It is worth noting that the noise optimization control system for the sanitation vehicle actuator in this embodiment further includes a first proximity switch 15 and a second proximity switch 16. The control terminals of the first proximity switch 15 and the second proximity switch 16 are electrically connected to the controller, respectively, for detecting the position of the hydraulic cylinder 3 and outputting the corresponding position detection data to the controller. The position detection data includes: the extension position data detected by the first proximity switch 15 and the retraction position data detected by the second proximity switch 16. Furthermore, the controller also controls the first reversing valve 6 or the second reversing valve 7 to switch from the working position to the normal position based on the position detection data.

[0059] In practical applications, when the actuator needs to extend, the controller energizes the electromagnet YV1 of the first directional valve 6, allowing compressed air to enter the rodless chamber of the directional cylinder 8. This pushes the directional cylinder to extend and causes the main directional valve 2 to switch its working position, thereby driving the actuating cylinder 3 to extend. When the actuating cylinder 3 extends to its normal position, the first proximity switch detects the extension completion data and sends it to the controller. Based on the received extension completion data, the controller de-energizes the electromagnet YV1 of the first directional valve 6, causing the first directional valve to switch back to its normal position. At this time, the compressed air is discharged into the atmosphere through the first air path damper 11 (which slows down the exhaust speed and reduces noise) and the third air path damper 13 (which further controls the exhaust flow).

[0060] Correspondingly, when the actuator needs to retract, the controller energizes the electromagnet YV2 of the second directional valve 7, allowing compressed air to enter the rod chamber of the directional cylinder 8. This pushes the directional cylinder to retract and causes the main directional valve 2 to switch its working position, thereby driving the actuating cylinder 3 to retract. When the actuating cylinder 3 retracts to its final position, the second proximity switch detects the retraction completion data and sends it to the controller. Based on the received retraction completion data, the controller de-energizes the electromagnet YV2 of the second directional valve 7, causing the second directional valve to switch back to its normal position. At this time, the compressed air is discharged to the atmosphere through the second air circuit damper 12 (which slows down the exhaust speed and reduces noise) and the fourth air circuit damper 14 (which further controls the exhaust flow).

[0061] In summary, this embodiment, through the precise detection of the proximity switch, allows the controller to accurately determine the position of the hydraulic cylinder 3, thereby achieving precise control of the directional valve. Simultaneously, the air path damping in the first and second buffer components effectively slows down the flow speed of compressed air, reducing noise generated during operation switching and air pressure changes. Furthermore, the introduction of the proximity switch not only improves the system's control accuracy but also enhances its safety. For example, if the hydraulic cylinder 3 has not reached the designated position, the controller will not erroneously switch the directional valve, preventing potential system damage or safety accidents.
