Description

Technical Field

[0001] This invention relates to the field of new energy vehicle parts technology, and in particular to a novel electronically controlled slow-descent manual valve. Background Technology

[0002] Currently, most manual control valves in traditional heavy-duty vehicles adopt mechanical structures, resulting in low control precision and slow response speed. Especially in new energy electric heavy-duty vehicles, the control requirements for cylinder lifting are even higher. Existing manual control valves have a single control method, and most manual control valves only have basic air circuit opening and closing functions, which cannot achieve precise control of multiple gears. Furthermore, they are difficult to work in conjunction with the vehicle's electronic control system, which limits their application in electric vehicles. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel electrically controlled slow-descent manual valve.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel electrically controlled slow-descent manual valve includes a valve body. The valve body has a first movable chamber, a second movable chamber, and a third movable chamber for the movement of a first valve core, a second valve core, and a third valve core. A rotating bracket for mounting an adjusting component is provided on the upper surface of the valve body. A pressure plate is installed on the upper surface of the valve body, and an outer cover for covering the adjusting component is installed on the upper surface of the pressure plate.

[0006] The adjusting component includes a main lever and a PTO (Power Take-Off) device. The main lever and the PTO device are rotatably mounted on a rotating frame. A handle is fixedly connected to the main lever. The main lever is used to adjust the first valve core and the third valve core located at its bottom, and the PTO device is used to adjust the second valve core located at its bottom.

[0007] Furthermore, in a preferred configuration, the first valve core is vertically movable within the second movable cavity, and the valve body is connected to a third air passage on one side of the second movable cavity. The third air passage is provided with a third connector at the air port at the bottom of the valve body.

[0008] Furthermore, in a preferred configuration, the first valve core includes a push rod, which is disposed at the top of the second movable cavity, and the bottom of the push rod contacts the inner wall of the second movable cavity via a spring.

[0009] Furthermore, in a preferred configuration, the second valve core is vertically movable within the third movable chamber, and the valve body is connected to a fourth air passage on one side of the third movable chamber. The fourth air passage is provided with a fourth connector at the air port at the bottom of the valve body.

[0010] Furthermore, in a preferred configuration, the third valve core is vertically movable within the first movable cavity, and the valve body is connected to a second air passage on one side of the first movable cavity. The second air passage is provided with a second connector at the air port at the bottom of the valve body.

[0011] In addition, in a preferred configuration, the valve body is provided with plugs and retaining rings at the bottom of the first movable chamber, the second movable chamber, and the third movable chamber.

[0012] Furthermore, in a preferred configuration, the outer cover has a gear adjustment port for the movement of the handle, and the outer cover has a toggle port for the movement of the PTO power take-off on one side of the gear adjustment port.

[0013] In addition, a preferred structure is that the rotating frame includes rotating plates symmetrically installed on the two side walls of the top of the valve body, with a central column between the rotating plates, and the main lever and PTO power take-off rotatably mounted on the central column.

[0014] In addition, a preferred structure is that an air inlet is provided on one side of the valve body located in the second active chamber, and the air inlet is connected to the second active chamber through an air hole.

[0015] The valve body has an exhaust hole at the bottom, which is connected to a first air passage inside the valve body. The first air passage is connected to a first movable chamber and a second movable chamber.

[0016] The beneficial effects of this invention are as follows: This invention controls the first valve core, the third valve core, and the second valve core respectively through the main lever and the PTO power take-off, realizing multi-level operation such as cylinder lifting, lowering, and mid-stop. The control is precise and the response is rapid. The introduction of the PTO power take-off allows the manual control valve to be linked with the vehicle's electronic control system, expanding its application scenarios in new energy electric heavy-duty vehicles.

A handle 31 is fixedly connected to the main lever 32. The main lever 32 is used to adjust the first valve core 6 and the third valve core 8 located at its bottom, and the PTO power take-off 33 is used to adjust the second valve core 7 located at its bottom. The adjusting component 3 is used to realize multi-level adjustment.

[0031] The first valve core 6 is vertically movable within the second movable cavity 18. The valve body 1 is located on one side of the second movable cavity 18 and is connected to a third air passage 17. The third air passage 17 is located at the air port at the bottom of the valve body 1 and is equipped with a third connector 03. The first valve core 6 includes a push rod 61, which is located at the top of the second movable cavity 18. The bottom of the push rod 61 contacts the inner wall of the second movable cavity 18 through a spring 62.

[0032] In addition, the second valve core 7 is vertically movable in the third movable chamber 9, and the valve body 1 is connected to the third movable chamber 9 on one side with a fourth air passage 19. The fourth air passage 19 is provided with a fourth connector 04 at the air port at the bottom of the valve body 1. The fourth connector 04 is used to connect to the third movable chamber 9 to allow gas to flow.

[0033] Furthermore, the third valve core 8 is vertically movable within the first movable chamber 16, and the valve body 1 is connected to a second air passage 15 on one side of the first movable chamber 16. The second air passage 15 is provided with a second connector 02 at the air port at the bottom of the valve body 1, and the second air passage 15 is used for the flow of gas in the first movable chamber 16.

[0034] Meanwhile, the valve body 1 is equipped with plugs 05 and snap rings 06 at the bottom of the first movable chamber 16, the second movable chamber 18, and the third movable chamber 9.

[0035] The outer cover 2 has a gear adjustment port 21 for the movement of the handle 31, and a toggle port 22 for the movement of the PTO power take-off 33 is provided on one side of the gear adjustment port 21 on the outer cover 2. The gear adjustment port 21 is used to identify the adjustment of different gears.

[0036] Meanwhile, the rotating frame 5 includes rotating plates 51 symmetrically installed on the top two side walls of the valve body 1, with a central column 52 between the rotating plates 51.

When the handle 31 is in the middle position, it is in the middle stop state. At this time, the main lever 32 does not press down the first valve core 6 and the third valve core 8. When the handle 31 is rotated to make the main lever 32 rotate, and the third valve core 8 is pressed down during the rotation, it controls the lifting of the hydraulic cylinder and controls the opening and closing of the second air passage 15. When the main lever 32 is rotated in the opposite direction to press down the first valve core 6, it controls the lowering of the hydraulic cylinder and controls the opening and closing of the third air passage 17.

[0039] When the PTO power take-off 32 is activated, the PTO power take-off 32 presses down the second valve core 7, thereby controlling the opening and closing of the fourth air passage 19. The exhaust passage is realized through the exhaust port 11 in conjunction with the first air passage 12. The first connector 01 is the air intake source, used to input airflow.

The control is precise and the response is rapid. The introduction of the PTO power take-off 33 enables the hand control valve to be linked with the vehicle's electronic control system, expanding its application scenarios in new energy electric heavy-duty vehicles. The valve body 1 is equipped with multiple movable chambers and air passages, which are reasonably arranged and work with the plug 05 and the snap ring 06 to ensure airtightness.
