Abstract
The invention relates to a hand brake set for electric vehicles, in particular to a feedback regulation hand brake set for electric vehicles. The hand brake set comprises a pressure sensor disposed on a hand brake, an adder, a single-chip microcomputer, and a rotor speed measurer. The hand brake set for electric vehicles decreases wheel speed, guarantees safety driving and decreases wheel wear.
Description
Technical field
The present invention relates to a kind of battery-driven car hand brake device, especially a kind of battery-driven car hand brake device that has feedback regulation.
Background technology
The brake gear of battery-driven car mainly contains two kinds of mechanical braking brake and hand-operated brakes.There is the brake rubber block defective of wearing and tearing easily in the mechanical braking brake by the brake rubber block brake wheel.Hand-operated brake is converted to the grip of staff by pressure sensor the electric signal of brake wheel, but hand-operated brake is the process of an open loop control, at the speed of a motor vehicle right brake wheel of successor that lowered, this certainly will increase Tyte Wear, the period of service of the tire of minimizing.
Summary of the invention
Technical matters to be solved by this invention is the deficiency at the above-mentioned background technology, and the battery-driven car hand brake device is provided.
The present invention adopts following technical scheme for achieving the above object:
The battery-driven car hand brake device comprises the pressure sensor that is installed on the parking brake, adder, micro controller system, rotor speed measurement mechanism; Wherein,
Described rotor speed measurement mechanism is placed in the magnetic field range of rotor rotation generation, output termination adder first input end;
The described adder second input termination pressure sensor mouth, mouth connects micro controller system A/D port;
Described single-chip processor i/o port connects the motor power input end.
Further, the rotor speed measurement mechanism of described battery-driven car hand brake device is Hall switch sensor.
Further, the rotor speed measurement mechanism of described battery-driven car hand brake device comprises: lienar for Hall element and A and D converter, wherein, described lienar for Hall element is installed on the motor housing, lienar for Hall element mouth is connected with the A and D converter input end, and described A and D converter mouth is connected with the adder first input end.
The present invention adopts technique scheme, has following beneficial effect: manually reduce vehicle wheel rotational speed, reduced the wearing and tearing of wheel when guaranteeing safe driving.
Description of drawings
Fig. 1 is the scheme drawing of electric brake hand brake device.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
Battery-driven car hand brake device as shown in Figure 1 comprises the pressure sensor that is installed on the parking brake, adder, micro controller system, rotor speed measurement mechanism.The rotor speed measurement mechanism is placed in the magnetic field range of rotor rotation generation, output termination adder first input end.The adder second input termination pressure sensor mouth, mouth connects micro controller system A/D port.The single-chip processor i/o port connects the motor power input end.
The rotor speed measurement mechanism is Hall switch sensor; Also can be made up of lienar for Hall element and A and D converter, the lienar for Hall element is installed on the motor housing, and lienar for Hall element mouth is connected with the A and D converter input end, and the A and D converter mouth is connected with the adder first input end.
The rotor speed measurement mechanism transfers to adder after the rotor rotating speed of measuring is converted to electric signal.When the user imposed grip to pressure sensor, pressure sensor converted grip to electric signal and transfers to adder.Adder deducts difference that the grip electric signal obtains as the input of Chip Microcomputer A/D port with the rotor speed electric signal.Micro controller system is according to the be reduced instruction of motor speed of the difference of adder output.The instruction that reduces motor speed is the field voltage amplitude that reduces the motor input end.
To sum up, the present invention has considered the feedback of electronics rotor speed, in the time of in motor speed has dropped to battery-driven car safety traffic scope, adder reduces according to the difference that rotor speed electric signal, grip electric signal obtain, micro controller system reduces the instruction that this information adjustment reduces motor speed according to difference, thereby can avoid wheel consistent braking when the user imposes grip to pressure sensor, when guaranteeing safe driving, reduce the wearing and tearing of wheel.
