Specific embodiment
In conjunction with accompanying drawing, the present invention is described further.
Referring to Fig. 1 and Fig. 2, the present invention devises a kind of pedestrian protecting active arrangements for automotive doors brakes, including：Spacing
Arm, stop, connecting bracket, motor and brake unit it is characterised in that：Brake unit 3 side be fixedly arranged above drive
Galvanic electricity machine 4, the lower section of motor 4 is provided with fixing device for installing 7 and stopper 6, and fixing device for installing is fixed on brake unit 3
The same side on, stopper 6 is fixed on position limit arm, and the opposite side of brake unit 3 is fixed with stop 2, stop 2 with spacing
The generation spacing torque that matches of arm 1, the other end of position limit arm 1 is fixed with connecting bracket 5.
In the present invention, brake unit 3 includes：Brake unit housing 3-6, driving cam 3-5, activation lever 3-1, brake block
3-3 and back-moving spring 3-4, activation lever 3-1 is fixed on the both sides within brake unit housing 3-6, the central authorities of activation lever 3-1
It is fixed with contiguous block 3-2, brake unit housing 3-6 central authorities position on the lower side is then run through in one end of position limit arm 1, and the two of this end
Side is connected with brake block 3-3 respectively, and brake block 3-3 is then fixed on the lower section of activation lever 3-1, the upper end of activation lever 3-3
Fix with the 3--5 both sides phase of driving cam respectively, the lower end of activation lever 3-3 is then solid with the two ends phase of back-moving spring 3-4 respectively
Fixed, the central authorities of described driving cam 3-5 are fixed on the top of brake unit housing 3-6.
In the present invention, position limit arm 1 runs through the lower section positioned at contiguous block 3-2 for the position of brake unit housing 3-6.
In the present invention, the lower section of brake unit housing 3-6 position is run through in the position of back-moving spring 3-4 positioned at position limit arm 1.
Installing hole is offered on brake unit housing 3-6 between driving cam 3-5 and contiguous block 3-2 in the present invention.
Another installing hole is offered on brake unit housing 3-6 below back-moving spring 3-4 in the present invention.
In the present invention, motor 4 is Worm-gear type DC micromotor.
A kind of active arrangements for automotive doors braking method of pedestrian protecting is it is characterised in that be braked using following steps：
Step 1：Vehicle reversing radar signal is monitored to surrounding and monitoring signals is delivered to ECU control unit；
Step 2：ECU control unit research and application signal, and analysis result is converted into electric signal transmission to motor；
Step 3：Motor receives the signal of telecommunication of step 2, and the signal of telecommunication is judged：
A. positive rotaring signal：Motor is rotated forward, and drives driving cam to control activation lever, amplification power, locking car door
Open；
B. reverse signal：Motor is inverted, and drives driving cam to control activation lever, cancels active force, back-moving spring
Promote activation lever to reset, make the normal folding of car door.
The present invention increased a set of brake unit 3 in car door, after the automobile that can be detected using vehicle reversing radar
The signal that sidepiece has pedestrian or the close situation of vehicle and sends, and this signal is transferred to braking dress by ECU control system
Put 3, make motor 4 in brake unit 3 drive driving cam 3-5, and pass through activation lever 3-1 amplification power, to
The match two sides of position limit arm 1 of work of stop 2 are braked, and moment increases the unlatching of enabling resistance locking car door,
Thus avoiding the generation of accident, the present invention is made to have active defense function.
For the service life protecting motor and extend the present invention, after triggering braking, drive within the default time
There is power-off in motor 4, the system self-locking of the present invention simultaneously keeps on-position.
After radar for backing car detects outside pedestrian or vehicle leaves, ECU control system sends action command again, drives
Motor 4 inverts, and driving cam 3-5 is unclamped, and removes brake force, then motor 4 loss protecting, and back-moving spring 3-4 will drive
Lever 3-1 springs back to initial position, and car door just can be normally-open, and keeps original car door opening constant with closing performance.
Present invention narrow space in car door, using lever principle, using Worm-gear type DC micromotor with regard to energy
Produce enough clamping forces and carry out locking position limit arm 1 to brake the unlatching of car door, response time of the present invention is fast, can be in signal simultaneously
The moment sending just produces braking action, and back-moving spring 3-4 ensure that the normally-open, and not of car door when not needing to brake
The service life of car door limiter can be affected.The work of simultaneous brake 3, independent of stop 2, does not interfere with stop 2
Normal work, does not have any impact to the spacing performance of car door.
And the position that in the present invention, brake block 3-3 clamps position limit arm 1 is not the normal function surface of position limit arm 1, therefore
The normal work and use life-span of position limit arm 1 will not be affected because of brake wear, be also not result in stop 2 and position limit arm 1
Abnormal sound is produced during relative motion.
The brake unit of the present invention and stop cooperating, do not have any impact to conventional limit function and life-span,
And brake device structure is compact, fringe cost is not high, reliable, and working service is convenient, does not have after assembling with stop cooperation
There is special mounting to require, only need to incoming control signal when car load assembles, and can carry out when position limit arm designs suitably adding
Long.
