Mechanism can be used to actuating door and open.Especially lock assembly 12 is activated to allow to open door.
Door expanding unit 14 and 12 cooperative cooperating of lock assembly, door expanding unit are operatively connected to car door 11.In shown reality
It applies in example, door expanding unit 14 is arranged below lock assembly 12, it should be realized that this expanding unit 14 can be at one
It is located at lock assembly 12 nearby in the neighbor configuration form of substitution or is spaced from.Lock assembly in yet other embodiments,
12 and door expanding unit 14 can be set share shell in.
As used herein, the closed position of car door 11 refers to the fully closed position of car door 11, and therefore, door is not from vehicle body
It rises half-open.The half-open position of car door 11 refers to half-open position of the door relative to vehicle body, and the degree at door and vehicle body interval is enough to allow
User inserts a finger between the trim panel and vehicle body of car door 11, so that car door 11 be allowed to be removed to car door from half-open position
Fully open position.Fully open position refers to the position for allowing user to get on the bus.In some embodiments, half-open position is by car door 11
The gap less than about 50 millimeters between bodywork surface 16 limits.In some embodiments, half-open position by car door 11 with
The gap between about 10 millimeters to about 40 millimeters between bodywork surface 16 limits.
Referring to fig. 2, lock assembly 12 includes the lock bolt 20 being set on car door 11 and fixed vehicle structure 24 is arranged in
As vehicle B column or C column on lock 22.Lock bolt 20 and lock 22 are interconnected to keep car door 11 to be in full close position.Phase
As, door expanding unit 14 includes the actuator 26 being set on car door 11 and the actuating being set on fixed vehicle structure 24
Device striker 28.In addition, in some embodiments, actuator striker 28 can be set on car door 11, and door expanding unit 14 is set
It sets on fixed vehicle structure 24.
In some embodiments for example as shown in Figure 3, actuator striker 28 and lock 22, which are connected to, common hits button
Plate 30, to improve assembling cooperation and acceptable tolerance and further reduce the cost.But in other embodiments, lock 22 and actuator
Striker 28, which can be connected to, individually hits buckle 30.Furthermore in some embodiments, actuator striker 28 be retractable into
Just it is movable into and out fixed vehicle structure 24, manually or by the electromechanical means of motor etc..
Referring now to Fig. 4, one embodiment of actuator 26 is shown.Actuator 26 includes actuator casing 32, actuating
Device lid 34 and actuator over caps 36, they are mutually permanently connected and form actuator 26.Actuator over caps 36 and actuator cap 34
Top cover opening 38 and cover gab 40 are respectively included, to receive actuator striker 28.Referring now to Fig. 5 and Fig. 6, actuator is shown
26 partial view.Fig. 5 particularly illustrates actuator casing 32 and its inside components, including the driving mechanism for actuator 26
54.Motor 42 is arranged in actuator casing 32 to drive actuator 26 to work.Especially motor 42 drives worm screw 44 to rotate, snail
Bar engages with gear train 46 and drives the gear train.In an illustrated embodiment, which includes engaged with worm screw 44
One gear 48, with 50 common rotation of the first pinion gear.First pinion gear 50 drives second gear 52 to rotate.It should be appreciated that
Driving mechanism 54 as shown in Figure 5 and as described herein is only exemplary, within the scope of the present invention it is contemplated that other drivings
Mechanism 54 configures.
Referring now to Fig. 6, actuator 26 is shown, actuator over caps 36 is removed at this time.Cam 56 is located at actuator cap
In 34 and it is connected to second gear 52, so that the rotate driving cam 56 of second gear 52 is rotated around camshaft line 58.Cam
56 include cam path 60, with cam 56 around the rotation of camshaft line 58, the cam path and actuator striker 28 cooperate with
So that door 11 is moved on to half-open position from full close position, move on to full close position from half-open position, as will be described in further detail like that.
Referring now to Fig. 7, the plan view of actuator 26 is shown, actuator over caps 36 is for the sake of clarity moved at this time
It removes.Cam path 60 includes slot entrance 62 on the periphery of cam 56 72, and slot entrance is directed at top cover opening 38 and cover gab 40.From slot
Entrance 62 rises, and cam path 60 is extended radially inwardly to camshaft line 58, then moves ahead along curve part 64, which includes in slot
Wall 66 and slot outer wall 68, herein, slot inner wall 66 is than slot outer wall 68 closer to camshaft line 58.Curve part 64 is extended in cam
Slot outlet 70 on 56 periphery 72.It is thusly-formed and designs cam path 60, so that actuator striker 28 is assemblied in slot inner wall 66
Between slot outer wall 68.In addition, reset switch 74 is interconnected with switching cam 76, switching cam is coaxial with cam 56 and therewith
Rotation.The cam 56 when car door 11 is in full close position and actuator striker 28 is shown in FIG. 7, at this time actuator striker
28 are located at reset position 78, which is the intersection point of curve part 64 Yu slot entrance 62 in some embodiments.
Referring now to Fig. 8 a-8d, by description door opening sequence or door expansion sequence.In Fig. 8 a, once receive an expansion
Signal just rotates cam 56 80 around camshaft line 58 along clockwise direction by driving mechanism 54.When cam 56 rotates, cause
Move 28 arrival curve portion 64 of device striker and against slot inner wall 66.When cam 56 just as continuing along clockwise direction in figure 8b
When 80 rotation, the car door 11 including actuator 26 is forced toward half-open position, which keeps left in figure.In Fig. 8 c,
Striker 28 shifts to the stop place 82 close to slot outlet 70.On stop place 82, actuator striker 28 is also engaged in cam
In slot 60, prevent car door 11 for example mobile to fully open position from half-open position because wind or vehicle are parked on ramp.
When car door 11 is in half-open position, user can catch or contact door along 84 (as shown in Figure 1) and operate pair
Sensor or switch 86 will force cam 56 into door releasing position as shown in figure 8d at this time, and actuator striker 28 passes through at this time
Slot outlet 70 proceeds to the free position outside cam 56.This allows car door 11 relative to 28 free movement of striker.
Referring now to Fig. 9, when cam 56 shifts to releasing position, 62 alignment actuator striker 28 of slot entrance.This allows
Actuator striker 28 shifts to reset position 78 straight across slot entrance 62, if what user sufficiently rapidly closed the door
Words.
But if the closing of car door 11 not enough rapidly carries out, then motor-driven closing is used by actuator 26.It will be referring to figure
10a-10e describes motor-driven closing.Referring to Figure 10 a, when car door 11 is not enough rapidly closed, actuator striker 28 is shifted to along convex
Secondary position 88 of the race 60 between slot entrance 62 and reset position 78, and car door 11 is in half-open position.Motor-driven closing is with convex
Around camshaft line 58,90 rotations start wheel 56 in the counterclockwise direction.When cam 56 rotates as shown in fig. lob, actuator striker 28
It is moved into auxiliary cam slot 92 towards guide card 94, which separates auxiliary cam slot 92 and curve part 64.Guide card 94 is pivotly solid
Determine to cam 56, so that guide card 94 rotates and allows around direct pivot 96 when actuator striker 28 is forced on guide card 94
Actuator striker 28 moves into curve part 64 from auxiliary cam slot 92, as shown in figure l0c.As cam 56 continues around camshaft line 58
Rotation, as shown in fig. 10d, actuator striker 28 are advanced along the slot outer wall 68 of curve part 64, and car door 11 is drawn from half-open position
To full close position.In figure 10e, cam 56 shifts to reset position, and actuator striker 28 is in reset position 78 and therefore at this time
Car door 11 is in full close position.
Door expanding unit 14 as described herein provides following operation, and car door 11 is maintained at half-open position to prevent not at this time
Careful and/or uncontrolled car door 11 shifts to fully open position, such as is parked in ramp or injustice because of fitful wind or because of vehicle
On face.
