Abstract

[0002] With the development of construction machinery, electric loaders are increasingly widely used in agricultural machinery, construction machinery, and related fields, leading to higher demands for their expanded functionality. Currently, the speed of the hydraulic pump in electric loader control systems is controlled by a joystick, which is not adjustable, making precise operation difficult for users. Furthermore, since electric loaders are powered by electric motors, they offer greater scalability compared to traditional internal combustion engines. For example, the "kinetic energy recovery" function, which effectively reduces braking system losses in vehicles, is widely used in the automotive industry. However, loaders differ from passenger cars in their application; in addition to driving, they also perform operational tasks. Therefore, there is a need to design a new control system for electric loaders that can broaden their application range and improve their maneuverability and comfort. Utility Model Content

[0017] Please refer to the examples. Figure 1 , Figure 1 The diagram shown is a schematic diagram of an electric loader control system provided in an embodiment of this application.
[0018] An electric loader control system includes: an accelerator pedal for user operation to trigger the electric loader to move; a kinetic energy recovery mode switch for triggering the electric loader to decelerate; a high-speed oil pump switch for triggering the oil pump to run at a preset maximum speed when closed by user operation; and an oil pump operating mode switch for automatically controlling the oil pump to run at a user-defined speed.
[0019] like Figure 1 As shown, the new control system of the electric loader includes the following components: travel motor controller K01, oil pump motor controller K02, travel motor K03, throttle pedal K04, kinetic energy recovery mode switch K05, oil pump motor K06, potentiometer K07, oil pump high-speed switch K08, and oil pump working mode switch K09.
[0020] In some embodiments of this utility model, the above-mentioned electric loader control system further includes: an oil pump motor for driving the oil pump to run; and an oil pump motor controller for controlling the oil pump motor to start or stop.
[0021] In some embodiments of this utility model, the above-mentioned electric loader control system further includes: a handle; the input of the high-speed oil pump switch is connected to the output of the handle, allowing the user to manually operate and control the high-speed oil pump switch to open or close; the output of the high-speed oil pump switch is connected to the input of the oil pump motor controller, so as to control the oil pump motor to drive the oil pump to run at the preset maximum speed through the oil pump motor controller.
[0022] In some embodiments of this utility model, the above-mentioned electric loader control system further includes: a potentiometer for controlling the operating speed of the oil pump; the output of the oil pump operating mode switch is connected to the input of the oil pump motor controller, so as to drive the potentiometer to control the operating speed of the oil pump through the oil pump motor controller.
[0023] In some embodiments of this utility model, the high-speed switch of the oil pump and the working mode switch of the oil pump are connected in parallel.
[0024] In some embodiments of this utility model, the above-mentioned electric loader control system further includes: a travel motor for driving the electric loader to travel; a travel motor controller for controlling the start or stop of the travel motor; the output of the throttle pedal is connected to the input of the travel motor controller to control the travel of the electric loader; and the output of the kinetic energy recovery mode switch is connected to the input of the travel motor controller to reduce the power input to the travel motor controller by the throttle pedal.
[0025] In some embodiments of this utility model, the aforementioned walking motor controller is connected to the kinetic energy recovery mode switch so that when the kinetic energy recovery mode switch is off, the input power of the accelerator pedal is reduced by a first parameter value, and when the kinetic energy recovery mode switch is closed, the input power of the accelerator pedal is reduced by a second parameter value.
[0026] In some embodiments of this utility model, the first parameter value is 70%; the second parameter value is 30%.
[0027] When the oil pump operating mode switch K09 is open, the user operates the handle, and the oil pump high-speed switch K08 is closed. The input terminal of the oil pump high-speed switch K08 is connected to the first power supply, and the corresponding pin of the oil pump motor controller K02 receives a high-level signal from the first power supply. The oil pump motor K06 then operates at the set maximum speed. When the oil pump operating mode switch K09 is closed, the input terminal of the oil pump operating mode switch K09 is connected to the second power supply, and the corresponding pin of the oil pump motor controller K02 receives a high-level signal from the second power supply. At this time, the oil pump high-speed switch K08 is disabled, and the speed of the oil pump motor K06 is controlled by the potentiometer K07. The user can adjust the speed of the oil pump motor according to the working conditions.
[0028] When the kinetic energy recovery mode switch K05 is open, the travel motor controller K01 reduces the voltage value input to the travel motor controller via the accelerator pedal K04. For example, the travel motor controller K01 recovers 70% of the power of the travel motor K03 (the specific value can be changed by adjusting the parameters of the corresponding travel motor controller). The input terminal of the kinetic energy recovery mode switch K05 is connected to a third power source. When the kinetic energy recovery mode switch K05 is closed, after receiving the trigger signal from the third power source, the travel motor controller K01 reduces the voltage value input to the travel motor controller via the accelerator pedal K04. For example, the travel motor controller K01 recovers 30% of the power of the travel motor K03 (the specific value can be changed by adjusting the parameters of the corresponding travel motor controller).
[0029] In summary, the electric loader control system provided in this application includes: a throttle pedal for user operation to trigger the electric loader to move; a kinetic energy recovery mode switch to trigger deceleration of the electric loader; a high-speed oil pump switch to trigger the oil pump to run at a preset maximum speed when closed by user operation; and an oil pump operating mode switch to automatically control the oil pump to run at a user-defined speed.
