Principle of work:
When need carry out glancing impact to vehicle, pull-up shift knob 1, drive button panel 14 pull-ups, infrared ray through hole 15 (totally 7) moves simultaneously, after infrared power valve 20 detects the several holes of pull-up with infrared receiving tube 21, instruction is sent to circuit board module 105, then, 105 pairs of motors 106 of circuit board module send instruction, and motor 106 beginnings are just changeed, and send action to screw thread copper sheathing 119 by speed reducer assembly 118,119 rotations make thread rod 117 carry out inside moving linearly by the screw thread transmission, with pulling brake cable pull 115, drag-line support 114 is installed on the plastic stent of car chassis and makes sliding motion, so that the automobile back wheel stress balance, brake cable pull 115 drives cable connector 113 simultaneously, cable connector 113 with tension trailing wheel brake cable pull, plays the effect of system power with being connected for automobile back wheel system power drag-line.
When infrared power valve 20 always finishes 7 holes with infrared receiving tube 21 detectings are infrared by hole 15, then wiring board command request motor 106 rotates the braking force that reply automobile back wheel brake cable pull applies 130kg, after pulling force sensor 122 detects nominal force and reaches, then feed back to circuit board module 105, circuit board module 105 promptly instructs motor 106 to quit work;
When release switch button 1, then shift knob 1 is owing to the pressure of spring 11, and shift knob returns to previous status.
When need are carried out releasing system power to vehicle, then the pull-up shift knob 1, click switching button 3 simultaneously, it is descending to drive switch slide block 19, make it push micro-switch 18, then this moment, circuit board module 105 was by arriving instruction, next should remove action, after shift knob 1 was moved the position to, slow release shift knob 1 was when infrared ray power valve 20 and infrared receiving tube 21 detect infrared by hole 15 during through 1, then circuit board module 105 order motors 106 are carried out counter-rotating, and require its pulling force to reduce to per centum of nominal value, by that analogy, when all cover in 7 holes, promptly start button when being discharged into original position, then pulling force is reduced to 5kg, and when the releasing system of execution power, other operating principles are identical with the operation of system power.
Indicator light colors: when system was in braking mode, indicator lamp 22 colors were red, showed by leaded light post 2, and when system was in disarm state, indicator lamp 22 colors were green.
When automobile is in braking mode, and storage battery does not have electricity or other reasons, when system can not remove, can be by pulling emergency unchaining drag-line 112, driving rotation pin 136 rotates emergency unchaining piece 135, screw thread copper sheathing 119 and pulling force sensor 122 are thrown off,, but reach the trailer purpose so that system's pressure becomes disarm state.

The principle of work explanation
A) tie bar space detects: adopt far-infrared sensor.In order to differentiate the pull bar travel direction, (every pair has an infrared transmitting tube and infrared receiving tube to adopt two pairs of opto-electronic pickups, LT1 and LR1 are a pair of among the figure, LT2 and LR2 are a pair of, LT1, LT2 are infrared transmitting tube, and LR1, LR2 are infrared receiving tube), the certain distance that staggers before and after two pairs of opto-electronic pickups, and two rounds are side by side.Every row has 7 holes, and shown in 8 figure: adoptor is installed on the mainboard, and power valve is installed on the platelet parallel with mainboard.Saturation conduction when adoptor receives tube-launched infrared signal, its collector voltage approaches 0V, i.e. logical zero.Do not end when adoptor receives tube-launched infrared signal, its collector voltage approaches 5V, is logical one.Microcontroller U9 is by reading in the state of two infrared receiving tube LR1 and R35, LR2 and R36, just the distance that can differentiate the pull bar travel direction and be pulled through, microcontroller U9 is Parking, moves back and stop that by the condition discrimination that reads in SW pine was stopped when SW was low level, tightly stops during for high level.
B) the U9 microcontroller receives drive plate state (tightly stop, pine stop) information by serial ports RXD, serial ports TXD, and by indication of anode light pipe and the meter lamp indication altogether of R37, R38, LED red and green color.Aerotron Q9, resistance R 39, R40, R41, electric capacity D9 module are used for providing status signal to instrument among the figure.At the pine state of stopping, LED double color luminotron green light bright (aerotron Q9 by).Tightly stopping is the Parking state, LED double color luminotron red light bright (aerotron Q9 saturation conduction).In brake process, green light bright always (aerotron Q9 ends) becomes red light bright (aerotron Q9 saturation conduction) after brake puts in place.In pine (moving back) was stopped process, red light bright always (aerotron Q9 saturation conduction) became green light bright (aerotron Q9 ends) after complete pine (moving back) is stopped.
