Description

Technical Field

[0001] The utility model relates to the field of pure electric sweepers, and in particular to an intelligent speed regulating system for pure electric sweepers. Background Art

[0002] With the acceleration of urbanization, the expansion of urban area and the increase in population, the amount of urban garbage has also shown explosive growth. Against the background of the continued promotion of air pollution control around the world, new energy sanitation vehicles have become the future trend, especially the market demand for pure electric sweepers will become increasingly larger.

[0003] At present, in order to realize automatic control and reduce the operating burden of the driver, the existing pure electric sweepers are not only convenient for the driver to adjust the motor speed of the high-pressure water pump, low-pressure water pump, gear oil pump, left sweeping disc, right sweeping disc and other cleaning devices by setting different knobs, but also designed a one-key operation button on the touch screen. After the driver presses the one-key operation button, the value pointed by the knob can be automatically shielded, and the motor speed of the above-mentioned cleaning device can be directly and automatically adjusted according to the set value to the corresponding speed of different working modes. The specific working modes include cleaning mode, enhanced mode, etc.

[0004] However, when the sweeper is working, there are often vehicles or pedestrians approaching, and it is difficult for the driver to take full account of them. As a result, when the above-mentioned cleaning device performs water spraying, cleaning and other tasks, especially when the cleaning device has a high speed in the enhanced mode, it is easy to accidentally injure surrounding vehicles or pedestrians. When the driver notices that a vehicle or pedestrian is approaching, the adjustment command of the knob will be blocked when the one-touch operation button is pressed. Therefore, the driver needs to release the one-touch operation button first and then adjust the motor speed of the corresponding cleaning device through the knob to avoid accidental injury to vehicles or pedestrians. However, this is difficult for the driver who needs to drive the sweeper synchronously to do in time, resulting in the inability to adjust the motor speed of the cleaning device in time to protect the surrounding vehicles or pedestrians approaching.

[0005] The purpose of this utility model is to design an intelligent speed control system for a pure electric sweeper in view of the problems existing in the above-mentioned prior art. Utility Model Content

[0032] A plurality of special motors are connected to the main controller respectively, and the special motors are used to drive the corresponding cleaning devices to work respectively;

[0033] The main controller is used to control the first switch K1 or the second switch K2 to be closed or opened. When the main controller receives the first signal, it controls the second switch K2 to be opened and adjusts the speed of the dedicated motor through the first signal. When the main controller receives the third signal, it controls the first switch K1 to be opened and the second switch K2 to be closed, and adjusts the speed of the dedicated motor through the second signal.

[0034] Specifically, in this embodiment, the main controller is an MCU, the first switch K1 and the second switch K2 are respectively the first contactor and the second contactor, the MCU sends a closing signal to the first contactor or the second contactor to trigger the first contactor to close or the second contactor to close, the MCU sends a disconnection signal to the first contactor or the second contactor to trigger the first contactor to disconnect or the second contactor to disconnect, and the controller controls the first switch K1 and the second switch K2 to close or disconnect, which is the prior art, and can be referred to the prior application with application number CN202123431842.7 and the name of battery pack, which will not be repeated here.

[0035] The above structure cooperates with the controller through the first switch K1, the second switch K2. After the first switch K1 and the second switch K2 are closed, when the control panel sends the first signal to the main controller, the main controller disconnects the second switch K2 and adjusts the speeds of several special motors through the first signal, thereby realizing a one-key adjustment mode.
