Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In specific implementation, as shown in fig. 1-3, an intelligent cooling device for a drum brake of a commercial vehicle comprises a vehicle body A, the vehicle body is provided with a cooling component, a rainwater collector 7 and an electric control component, the cooling component comprises an electric water spraying device 1 and a water tank 4, the water tank 4 is fixedly arranged on the vehicle body A, the electric water spraying device is arranged below the vehicle body A and close to the brake, the electric water spraying device 1 is connected with the water tank 4 through a pipeline, the rainwater collector 7 is arranged at the top end of the vehicle body A, an electric valve 6 is arranged outside a water outlet 702 of the rainwater collector, and is connected with the water tank 4 through a pipeline, the electric control component comprises an electric control box 3, a display 8 and a plurality of sensors, the electric control assembly is electrically connected with the cooling assembly, the electric valve and the display.
In this embodiment, a flow guide surface 701 is disposed inside the rainwater collector 7, and a water outlet 702 of the rainwater collector 7 is disposed at a lower end of the flow guide surface.
In this embodiment, the sensor includes a laser temperature sensor 2 disposed below the vehicle body a and near the brake, a water tank water level detection sensor 5 disposed in the water tank 4, a brake pedal displacement sensor 9 disposed at the brake pedal of the vehicle body a, and a GPS sensor 10 disposed in the vehicle body a.
In this embodiment, the electrically operated valve 6 is an electrically operated three-way valve, and three ports of the electrically operated valve, a first port is communicated with the water outlet 701 of the rainwater collector 7, a second port is communicated with a pipeline communicated with the water tank 4, and a third port discharges rainwater outside the vehicle.
In this embodiment, a filtering device is disposed in the rainwater collector.
As shown in fig. 3, the control logic of the electric cabinet is as follows: the laser temperature sensor can provide temperature information of the drum brake, the brake pedal position sensor can determine whether the vehicle is in a braking state, and then the single chip microcomputer starts to time the signal. After the GPS positioning sensor determines the current position of the vehicle, the length of a downhill road in front of the vehicle can be acquired by combining a geographic information system. When the temperature of the brake is higher than a certain threshold value, the braking time is longer than a certain threshold value or the length of the downhill road is longer than a certain threshold value, the electric water spraying device can start to spray water for cooling. And conversely, when any two signals in the three input signals do not meet the water spraying condition, the electric water spraying device stops spraying water. The water level sensor of the water tank can provide water tank water level information for the single chip microcomputer, when the water level in the water tank is lower than a certain threshold value, the electric three-way valve can communicate the rainwater collector with the water tank, and when rainwater falls onto the rainwater collector, the rainwater can flow into the water tank through the filtering device and the electric three-way valve; on the contrary, the electric three-way valve can guide the rainwater in the rainwater collector to the outside of the vehicle.
The working principle and the process of the utility model are as follows:
the electric control box obtains vehicle braking time information through a brake pedal position sensor, obtains the temperature of the drum brake through a laser temperature sensor, finally determines the position of the vehicle through a GPS positioning sensor, obtains the road gradient of the current position of the vehicle by combining a geographic information system, and judges whether to start or stop water spraying and cooling through control logic in the electric control box. In addition, the rainwater collector comprises a filtering device and an electric three-way valve, and the electric cabinet judges the state of the electric three-way valve in the rainwater collector according to a water level signal output by a water level detection device in the water tank. One end of an electric three-way valve in the rainwater collector can enable rainwater to flow into the water tank, and the other end of the electric three-way valve can enable rainwater to flow out of the vehicle. And finally, displaying various signals acquired by the electric control box through the sensor to a driver through a display, wherein the signals comprise warning of too low water level of the water tank and displaying the temperature of all wheel brakes.
