Technical field
The present invention relates to the control of automobile tail gate neck more particularly to contactless control tail-gate technologies.
Background technique
Whole process speed is consistent when the method for operation of traditional automobile tail gate is tail-gate operation, excessive velocities or all can slowly excessively
It brings inconvenience to using, in general, if adjusting door closing speed in door closing procedure, needs to be equipped with a set of responsible circuit system
System, then lacks that a kind of circuit structure is simple, and input cost is low at present, and is capable of the circuit of gearshift adjustment automobile power back door
Structure.
Summary of the invention
The technical problem to be solved by the present invention is to realize a kind of control circuit by electric tail gate speed Control.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of electric tail gate control circuit, circuit are equipped with
Master chip, the control signal of master chip output driving motor work, device are equipped with driving chip, the driving chip it is defeated
Enter the control signal output of end connection master chip, two output ends of the driving chip are separately connected two separate relays
The direct current of the control terminal of unit, the output end output different directions of two relay units is electrically accessed motor, described in two
The power input of relay unit, accesses the output end of half bridge chip, and the output end of half bridge chip is exported to relay
The supply voltage of different duty, the relay control output is by the modulated supply voltage of half bridge chip as electricity
Machine operating voltage.
The driving chip is Darlington driving chip, model MC1413.
The MOS half-bridge driven chip of half bridge chip, model BTN8962.
The relay is motor supply current commutation component, model ACTE3C5V01.
The movement of switch tail-gate, the master chip export the speed-regulating signal in three friction speed areas to motor, are respectively every time
The accelerating region of beginning, the at the uniform velocity area of pilot process and last deceleration area.
The present invention uses Darlington transistor, half bridge chip and relay joint driving tail door supporting rod electric machine speed regulation operation,
Circuit structure is simple, easy to popularize, and electric tail gate traffic coverage is divided into three speed areas, that is, the accelerating region started, in
Between process at the uniform velocity area, and the deceleration area of mechanism limit point will be reached, the noise that tail-gate overall operation can be made to generate, fortune
It is capable not smooth, and the damage of mechanism is preferably minimized, it ensure that the reliability that operation uses.
Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
Fig. 1 is half bridge chip connection schematic diagram；
Fig. 2 is relay drive circuit structural schematic diagram；
Fig. 3 is Darlington relay driver connection schematic diagram；
Fig. 4 is conventional full bridge circuit diagram.
Specific embodiment
Below against attached drawing, by the description of the embodiment, for example related each component of a specific embodiment of the invention
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
The controller of an electric tail gate control circuit i.e. entirety, electric tail gate have the motor of control tail-gate work, control
Device processed can control tail door supporting rod positive and negative rotation of motor, can also be needed according to different to the tail door supporting rod motor in operational process
Apply different effective voltages, the revolving speed of tail door supporting rod motor is controlled, to control the rate of tail-gate opened or closed.Pass through
Electric tail gate controls speed regulation and the switch of motor control tail-gate, so that tail-gate mechanical movement is more smoothly, mechanical damage is smaller.
Master chip be vehicle have control tail-gate function MCU, master chip have and tail-gate switch it is associated input and it is defeated
Pin out, input pin link control module, tail-gate switch key such as interior, at tail-gate, and interface tail-gate closed state
Sensor signal, output pin output motor work control signal.
It is Darlington driving chip, model MC1413 present invention employs driving chip.The input terminal of driving chip connects
The control signal output of master chip is connect, the control signal that master chip issues is received, two output ends of driving chip connect respectively
The control terminal of two separate relay units is connect, as shown in Figure 2,3, the pin 15 and 16 of driving chip connects two relay lists
The control terminal of member, is separately connected the pin 15 and 16 of driving chip after the control terminal of two relay units is in parallel with pressure stabilizing IC,
Two relays control output senses of current, so that control motor rotates and reverse operation.The output end of relay unit
The direct current of different directions is exported, two-way direct current connects connect after a resistance with resistance R15 respectively, and the resistance R15 has
Current limiting effect, the output end access master chip of resistance R15 are used as the working condition of detection motor.
PWM motor operating voltage of the output end of half bridge chip to relay output different duty.Half bridge chip uses
MOS half-bridge driven chip, model BTN8962.The output end of half bridge chip connects relay power input terminal.
The movement of switch tail-gate, the master chip export the speed-regulating signal in three friction speed areas to motor, are respectively every time
The accelerating region of beginning, the at the uniform velocity area of pilot process and last deceleration area.Half-bridge scheme adds relay to add half using Darlington
Bridge chip, circuit reliability are higher than the circuit that full-bridge chip adds 4 road MOS to form, and the defencive functions such as dead zone of half-bridge scheme are than complete
