Wherein body hinge hold-down support 1 is rigidly connected with screw rod 16, and 16 right end of screw rod is equipped with nut 13；Body hinge is consolidated
Determine bearing 1 and be automatically separated between bearing 3 first thrust bearing 2 is housed；It is automatically separated 3 and first guiding valve 6 of bearing and (passes through spiral shell
Line) rigid connection；The first prefastening force spring 4,4 right end of the first prefastening force spring and the second thrust bearing are cased with outside first guiding valve 6
14 are in contact, and left end is in contact with being automatically separated 3 inner surface of bearing, and the first prefastening force spring 4 is in compression shape after installation is complete
State；Second thrust bearing, 14 right end is contacted with 9 left side of base mandrel；The groove of first guiding valve, 6 right end and the second guiding valve 10
The boss of left end cooperates, both leave certain gap between end face, the output shaft of the second guiding valve 10 and motor rigidly connects
Connect；The inside of first guiding valve 6 is equipped with the second prefastening force spring 5, and the second prefastening force spring 5 is sleeved on outside screw rod 16, and left end passes through the 4th
Thrust bearing 17 is in contact with being automatically separated 3 inner surface of bearing, and right end is connected by the 3rd thrust bearing 15 with the left side of nut 13
Touch, nut can be moved in 6 inner horizontal of the first guiding valve, and the second prefastening force spring 5 is in compressive state after installation is complete；Outside base
Axis 8 is equipped with skewed slot and elongated slot, and skewed slot top is docked with elongated slot low order end；Be automatically separated 7 axis pins of 3 right end outer surface of bearing with
Skewed slot on base outer shaft 8 is engaged；Loaded on motor output shaft, crash sensor is installed on car rotary angle transmitter 11, is turned
The output terminal of angle transducer and crash sensor is connected with controller；Connect buzzer；Body hinge fixes branch with body hinge
Seat 1 is connected, and base 12 is fixed on vehicle body.
Since the first prefastening force spring 4 and the second prefastening force spring 5 are in compressive state after the installation is complete, first is pre-
The right end of clamp force spring 4 is the second thrust bearing 14 not being axially movable, and the left end of the first prefastening force spring 4 is to be automatically separated
Bearing, and axis pin is stopped be subject to base outer shaft skewed slot, thus 4 left end of the first prefastening force spring have promotion be automatically separated bearing to
The trend moved left；And the left end of the second prefastening force spring 5 is the 4th thrust bearing 17 that is not axially movable, the second pretightning force
The right end of spring 5 is connected by the 3rd thrust bearing 15 with nut, and nut can be moved in 6 inner horizontal of the first guiding valve,
So under the action of the second prefastening force spring 5, the 3rd thrust bearing 15 promotes to the right nut, and nut pulls car door by screw rod
Hinge hold-down support moves right, so that car door hold-down support is abutted against on the left side of the first thrust bearing 2, and first
Thrust bearing 2 can not be moved right by the stop for the right side for being automatically separated bearing, therefore the 3rd thrust bearing 15, nut, spiral shell

Carry out analysis contrast and obtain the collision information of vehicle；Judging vehicle, there occurs (when sharp impacts occur for vehicle, collided during collision
Sensor detects the collision information of vehicle, and sends to controller), controller sends what is opened and rotate counterclockwise to motor
Signal, rotates counterclockwise motor.Controller constantly gathers the angular signal of rotary angle transmitter during motor rotates,
Draw the angle that motor rotates.If it is A that elongated slot circumferential direction line of symmetry forms plane with base axis, axis pin radius is Rmm, in pin
Axis normal mounting in place under conditions of, i.e., when axis pin is located at skewed slot bottom, the angle between the axis and plane A of axis pin is α, and
The horizontal distance of axis pin axis to elongated slot low order end is Lmm, then when motor output shaft corner is α, then limit of the axis pin in skewed slot
Move right L-Rmm under system, and axis pin can align with elongated slot just at this time.When controller detects that the angle that motor rotates is lucky
When going to axis pin to align with elongated slot, i.e., when the axis of axis pin and the axis of elongated slot are in a plane, controller control motor
Stop operating.It is automatically separated horizontal restraint power between bearing and base at this time to disappear, being automatically separated bearing will be in the first pretightning force bullet

The signal of work, at this time buzzer start to prompt passenger car door can with passive open, at this time passenger can directly to
Gently car door is promoted to make its opening outside.
Only when the first crash sensor and the second crash sensor are simultaneously emitted by collision alarm, controller control motor
Rotate；When only the first crash sensor or the second crash sensor send collision alarm, controller does not control motor to rotate.It is logical
Crossing the setting can be to avoid false triggering, during such as car inspection and repair, and maintenance personal may cause crash sensor that false touch occurs so that the
One crash sensor sends collision alarm, but because the second crash sensor being now placed in driver's cabin will not send collision letter
Number, controller will not control motor to rotate；Only when vehicle entirety inertia reaches the first crash sensor and the second collision sensing
When device is simultaneously emitted by collision alarm, controller can just control motor to rotate at this time so that car door can be with passive open.
After vehicle collides, and body hinge hold-down support piece-rate system has completed work.At this time, if it is non-because
Vehicle deformation causes car door not open normally, then need to will only be automatically separated bearing in the state of motor stopping and promote pressure to the right
Contract the first prefastening force spring 4, until axis pin is moved to base outer shaft elongated slot low order end, then presses clockwise direction in Fig. 3 again
