Description

Technical Field

[0001] This utility model relates to the technical field of control handles for engineering vehicles, and in particular to a control handle for a proportional solenoid valve of an engineering vehicle. Background Technology

[0002] An engineering vehicle is a type of construction machinery that uses its own working devices to complete the leveling, excavation, and transportation of earthwork. The actions of the various working devices on the engineering vehicle are mostly driven by hydraulic cylinders. In order to facilitate the control of the hydraulic cylinders, corresponding control handles are installed in the cab of the engineering vehicle so that the operator can operate the working devices.

[0003] To achieve precise control of the hydraulic cylinder's movements, a proportional solenoid valve is typically installed in the cylinder's oil circuit. This valve is controlled by a handwheel on the control handle. However, using a traditional proportional solenoid valve handwheel to control the proportional valve can easily increase operator finger fatigue and reduce finger comfort. Utility Model Content

[0030] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0031] See Figure 1 , Figure 2 and Figure 4This utility model provides a proportional solenoid valve control handle for an engineering vehicle, including a handle body 1. The handle body 1 is provided with control buttons 2 and a handwheel 3 for controlling the proportional solenoid valve. Two control buttons 2 can be provided, and the two control buttons 2 are respectively located on the upper and lower sides of the handwheel 3. During control, the positions of the control buttons 2 are ergonomically designed for easy pressing. The two control buttons 2 can be configured with corresponding control functions according to usage requirements. Specifically, the control button 2 on the upper side of the handwheel 3 can be a parking button, and the control button 2 on the lower side can be a horn button.

[0032] The hand dial 3 includes a housing 31, a rotating base 32, a rotating body 33, and a dial body 34 mounted on the handle body 1. The housing 31 is provided with a receiving groove 311. The rotating base 32 is installed in the receiving groove 311 and is clamped between the rotating body 33 and the dial body 34, so that the rotating body 33 and the dial body 34 are rotatably connected to the rotating base 32. The dial body 34 is provided with a dial plate 341. The dial plate 341 has an arc-shaped structure, so that the side of the dial plate 341 away from the housing 31 forms an arc-shaped groove 342.

[0033] With the above structure, the dial body 34 can be rotatably connected to the rotating seat 32 through the cooperation of the housing 31, rotating seat 32, rotating body 33 and dial body 34 of the dial 3. A dial plate 341 is provided on the dial body 34 and the dial plate 341 is set into an arc-shaped structure, so that an arc-shaped groove 342 is formed on the dial plate 341. The shape of the arc-shaped groove 342 can fit the finger, so as to reduce the fatigue of the user when using the dial 3 and make the finger more comfortable when using it.

[0034] In one embodiment, see Figure 2 , Figure 3 and Figure 4 An arc-shaped limiting plate 321 is provided on the rotating seat 32, and a bushing 322 is provided on the rotating seat 32 corresponding to the axis of the arc-shaped limiting plate 321. The rotating body 33 is rotatably connected to the bushing 322.

[0035] The rotating body 33 includes a base 331, on which a rotating shaft 332 is mounted, and the rotating shaft 332 is rotatably connected to a bushing 322. In practical applications, the rotating body 33 and the rotating base 32 are rotatably connected through the cooperation of the bushing 322 on the rotating base 32 and the rotating shaft 332 on the rotating body 33, thereby allowing the dial body 34 to rotate relative to the rotating base 32 via the rotating body 33.

[0036] In one embodiment, see Figure 2 and Figure 3The arc-shaped limiting plate 321 has through grooves 323 between its two ends and the rotating seat 32. The rotating body 33 is provided with torsion springs 35, and the two ends of the torsion springs 35 pass through the through grooves 323 and are supported on both sides of the dial body 34.

[0037] The cross-section of the dial body 34 is arc-shaped, forming a concave arc surface on one side of the dial body 34 facing the housing 31. In practical applications, the through slot 323 allows the two ends of the torsion spring 35 to pass through the through slot 323 and be supported on both sides of the dial body 34. When the dial body 34 is turned, it rotates along the bushing 322 of the rotating body 33. One end of the torsion spring 35 abuts against the arc-shaped limiting plate 321, and the other end abuts against the dial body 34, allowing the torsion spring 35 to store force. When the dial body 34 is released, it returns to its original position.

[0038] In one embodiment, see Figure 2 and Figure 4 The dial body 34 is provided with a first connecting groove 343, the cross-section of the first connecting groove 343 is an arc-shaped structure, and the rotating body 33 is provided with a connecting block 333 that matches the first connecting groove 343.

[0039] The dial body 34 is provided with a limit post 344, and the rotating body 33 is provided with a limit hole 334 that matches the first limit post 344.

[0040] The dial body 34 is provided with a second connecting groove 345, which has a circular cross-section. The rotating body 33 is provided with a connecting post 335 that matches the second connecting groove 345. In practical applications, the cooperation of the first connecting groove 343 and the connecting block 333, the limiting post 344 and the limiting hole 334, and the second connecting groove 345 and the connecting post 335 can increase the connection stability between the dial body 34 and the rotating seat 32, so that when the dial body 34 is turned on, it can rotate relative to the rotating seat 32 via the rotating body 33.

[0041] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0042] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
