Description

Technical Field

[0001] This utility model relates to the field of engineering machinery parts, specifically to a handle for quickly switching blade control and an engineering machinery vehicle. Background Technology

[0002] The 3D automatic leveling system consists of a GNSS (Global Navigation Satellite System) receiver, a GNSS antenna, a radio module, an inertial navigation sensor, and a display and control terminal. In terms of installation, GNSS receivers are typically mounted on both sides of the blade, and an inertial navigation sensor is installed on the blade to measure its motion attitude and determine the real-time position coordinates of the blade tip. The difference between these coordinates and the design coordinates controls the blade's raising or lowering. When the difference is below the design surface, the blade is raised; when the difference is above the design surface, the blade is lowered. The switch controlling the automatic blade raising and lowering function is called the manual / automatic switch. In manual mode, the operator performs the blade movements; in automatic mode, the system performs the blade's operations.

[0003] However, in actual operation, there are often complex terrains and unexpected situations during construction. For example, in automatic operation mode, the shovel may get stuck on tree roots or rocks and cannot be pushed. In this case, it is necessary to switch the shovel control mode to manual mode. Then the driver can lift the shovel to allow the vehicle to pass and work. However, if the manual / automatic switch is constantly clicked to switch, there is a delay and it is not easy to operate. It will also be inconvenient in actual operation.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem in existing technologies where switching between automatic and manual modes requires continuous clicking of the manual / automatic switch, resulting in delays and inconvenience, this utility model provides a handle for quickly switching blade control. The handle for quickly switching blade control includes: a handle body and an electronic control system; the handle body includes a handle head and a handle shaft; a manual / automatic switch button is provided on the handle head, the button having a selectable first manual branch and a first automatic branch connected to the electronic control system; a quick-switch button is provided on the handle shaft, the quick-switch button being a push-button switch, having a selectable second automatic branch and a second manual branch connected to the first automatic branch, the second manual branch and the second automatic branch being connected to the electronic control system.

A manual / automatic switch button is provided on the handle head, having a first manual branch and a first automatic branch. A quick-switch button is provided on the handle body, having a second automatic branch and a second manual branch. When the first manual branch is connected to the electronic control system, the blade is in manual operation mode. When the first manual branch is disconnected and the first automatic branch is connected to the second automatic branch, the blade is in automatic operation mode. With the above configuration, this invention's handle for quickly switching blade control allows for rapid switching from automatic to manual operation mode by pressing the quick-switch button, and reverts to automatic operation mode upon releasing the quick-switch button. Operation is simple and convenient, eliminating the need for repeatedly pressing the manual / automatic switch button.

[0007] Furthermore, the handle has a front and a back side; the manual / automatic switch button is located on the front side, and the quick-switch button is located on the back side. With this arrangement, the quick-switch button is located on the back side and on the handle, allowing for convenient pressing and releasing, thus improving the user experience.

[0008] Furthermore, a one-button offset button connected to the electronic control system is provided on the handle, and the one-button offset button is arranged side by side with the manual / automatic switch button. With the above settings, after the one-button offset button is pressed, the electronic control system can automatically calculate the offset amount based on the difference between the current blade elevation and the design elevation, and fill it into the system, realizing the quick setting of the design offset amount without manual calculation, which facilitates operation.

[0009] Furthermore, an offset adjustment switch is provided on the handle head. This offset adjustment switch has selectable incremental and decremental branches that are connected to the electronic control system.

[0016] The 3D automatic leveling system consists of a GNSS receiver, GNSS antenna, radio module, inertial navigation sensor, and display and control terminal. In terms of installation, GNSS receivers are typically mounted on both sides of the blade, and inertial navigation sensors are installed on the blade to measure its motion attitude, thereby determining the real-time position coordinates of the blade tip. The difference between these coordinates and the design coordinates controls the blade's raising or lowering.

Major systems include the US GPS, Russia's GLONASS, China's BeiDou (also known as Compass), and the EU's Galileo. RTK: RTK (Real-time kinematic) carrier phase differential technology is a method for processing the carrier phase observations of two measurement stations in real time. The carrier phase data acquired by the base station is sent to the user receiver for differential calculation of coordinates. This is a new and commonly used satellite positioning measurement method that can achieve centimeter-level accuracy. GNSS signal receiver: used to receive GNSS satellite navigation signals; Inertial navigation sensor: Built-in inertial navigation module, mainly detects and measures acceleration, tilt, impact, vibration, rotation and multi-degree-of-freedom (DoF) motion. It is an important component for navigation, orientation and control of moving vehicles, and can output the motion attitude information of objects; Roll angle: A coordinate system is established with the center of the vehicle as the origin and the front-to-back direction as the Y-axis. The angle generated by the movement of the blade around the Y-axis is the roll angle. Pitch angle: A coordinate system is established with the center of the vehicle as the origin and the left and right directions as the X-axis. The angle generated by the movement of the blade around the X-axis is the pitch angle. Heading angle: A coordinate system is established with the vehicle center as the origin and the vertical upward direction as the z-axis. The angle generated by the movement of the shovel around the z-axis is the heading angle, which ranges from 0 to 360°. Offset: This is the height difference between the current location of the blade on the ground and the design surface position. By adjusting different offsets, different design surface requirements can be met.
