Wherein in an embodiment, the described drive unit that automatically latches is for the drive motors that latches, latch in body 9 described in the mechanism's axis of rotation 10 that automatically latches be connected with the described drive motors that latches inserts, the body 9 that latches comprises latch front end 93 and the end 94 that latches away from the described mechanism's axis of rotation 10 that automatically latches near the described mechanism's axis of rotation 10 that automatically latches, described extension 91 for described in latch end to away from described automatically latch mechanism's axis of rotation direction extend position, described resistance revolves portion 92 for being arranged on the first lobe of the end that latches;
When the described body 9 that latches is in lockup state, described extension 91 rotates to the space between described dead bolt 4 and described locking bar upper end, and described resistance is revolved portion 92 and rotated and coordinate compress described dead bolt 4 to above described dead bolt 4;
When the described body 9 that latches is in released state, described extension 91 rotates the top to described locking bar upper end and is supported by described locking bar upper end, and described resistance is revolved portion 92 and rotated to being separated with described dead bolt 4.
The body 9 that latches controls to rotate by the mechanism's rotating shaft 10 that automatically latches, and the mechanism's rotating shaft 10 that automatically latches connects the drive motors that latches.When pressing mechanical unlock button on automatically controlled unlock button or each door trim, the drive motors that latches is rotated to the mechanism's rotating shaft that automatically latches direction 18 of unblanking by the mechanism's rotating shaft 10 that automatically the to latch body 9 that controls to latch.When the drive motors that latches does not receive unlocking signal, the body 9 that latches can be allowed to keep latching to the mechanism's rotating shaft that automatically latches under the effect of deadweight the direction force in direction 17, but, also the drive motors that latches can be allowed to remain the direction force in certain direction 17 that latches to the mechanism's rotating shaft that automatically latches, ensure automatically to latch function.
Wherein in an embodiment, when the described body 9 that latches be in released state and when described dead bolt 4 to dead bolt unblank direction rotate and pull described spring drag-line 8 to be stretched to preset length time, described dead bolt 4 coordinates with described second lobe 95;
When described dead bolt 4 rotates to dead bolt unlocking direction, described dead bolt 4 is separated with dead bolt second lobe 95.
The second lobe 95 that the present embodiment increases, make when dead bolt 4 pulls described spring drag-line 8 to be stretched to preset length, dead bolt 4 can coordinate with the second lobe 95, hold out against the second lobe 95, thus dead bolt 4 is rotated produced active force and is converted to pressure to locking bar 6 to dead bolt direction 12 of unblanking by the second lobe 95 and extension 91, thus locking bar 6 is rotated better.
Wherein in an embodiment, described locking bar 6 comprises the vertical portion 63 and horizontal part 64 that form L-type structure, the top of wherein said vertical portion 63 is described support portion 61, the bottom of described vertical portion 63 is connected with one end of described horizontal part 64, and the other end of described horizontal part 64 is as described drive division 62.

Wherein in an embodiment, an integrated torque spring on described dead bolt axis of rotation 5.
Torque spring applies the torsion in a direction 12 of unblanking to dead bolt to dead bolt axis of rotation 5, user is opened the door more convenient.Meanwhile, can ensure to pull locking bar 6 to rotate by spring drag-line 8.
Fig. 2 is the direction schematic diagram of preferred embodiment, and all directions comprise dead bolt direction 11, dead bolt direction 12, enabling direction 13, direction 14 of closing the door, locking bar latch direction 16, automatically latch direction 17, the automatically mechanism that latches of mechanism that latch of direction 15, locking bar of unblanking of unblanking that latch and to unblank direction 18.
Its enabling stroke is: during opening car door, driver presses automatically controlled unlock button (or each position passenger presses mechanical unlock button on the respective door trim) body 9 that makes to latch and turns to withstood to the mechanism that automatically latches direction 18 of unblanking by locking bar 6 under the driving of the drive unit that automatically latches, i.e. state shown in state motion to Fig. 3 as shown in Figure 1.The body 9 that now latches is in released state, and its resistance is revolved portion 92 and removed prevention behavior to dead bolt 4, makes whole door latch structure be in opening.
The body 9 that latches controls to rotate by the mechanism's rotating shaft 10 that automatically latches, and the mechanism's rotating shaft 10 that automatically latches connects motor.When pressing mechanical unlock button on automatically controlled unlock button or each door trim, the Electric Machine Control mechanism's rotating shaft 10 that automatically latches rotates to the mechanism's rotating shaft that automatically latches direction 18 of unblanking.Remain that when motor does not receive unlocking signal certain mechanism's rotating shaft that automatically latches latches the active force in direction 17, ensures automatically to latch function.
Driver or passenger apply certain enabling power to direction outside car on door trim.The dead bolt 4 be arranged on door device moves to the direction of the vehicle with car door, namely moves to enabling direction 13, and simultaneously dead bolt 4 rotates by the unblank active force in direction 12 of dead bolt, until snap close 3 is deviate from from the dead bolt skewed slot 2 dead bolt 4, and car door opening.Now dead bolt front end 41 contacts with the second lobe 95 of the body 9 that latches.Namely state shown in from state motion shown in Fig. 3 to Fig. 4.
Preferably, an integrated torque spring on dead bolt axis of rotation 5, maintains a dead bolt all the time and to unblank the active force in direction, and force value is enough large, to ensure to pull locking bar mechanism to rotate by spring drag-line to dead bolt 4.
Dead bolt 4 is unblanked while the active force effect in direction 12 rotates by dead bolt, and the stressed stretching of spring drag-line 8 and the convergent force of spring drag-line 8 increase.When dead bolt 4 turn to contact with the second lobe 95 of the body 9 that latches time, the convergent force of spring drag-line 8 just in time increases to the 1 boundary's point pulling locking bar 6 to rotate.Now the convergent force of spring drag-line 8 is just in time offset locking bar and is latched the active force in direction 16 and the support portion 61 of locking bar 6 to the reaction force of the spacing power of the extension 91 of the body 9 that latches.Hold out against the second lobe 95 completely along with dead bolt 4 is rotated further dead bolt front end 41, locking bar 6 rotates, and removes the stop bit effect for the body 9 that latches.I.e. state shown in state motion shown in Fig. 4 to Fig. 5.Meanwhile, car door opening.
Locking bar mechanism axis of rotation 7 connects locking bar motor, and locking bar motor maintains a locking bar for locking bar 6 all the time and to latch the active force in direction 16.And the reaction force that this active force adds the spacing power of upper lock rod 6 pairs of extensions 91 equals the convergent force of spring drag-line 8 when dead bolt front end 41 contacts with the second lobe 95.Thus realize: first dead bolt front end 41 heads into the body 9 that latches, and contacts with the second lobe 95, plays the position-limiting action to the body 9 that latches, and is rotated further, and pulls locking bar 6 to rotate by spring drag-line 8, removes locking bar 6 to the position-limiting action of the body 9 that latches.
To close the door stroke: during closing of the door, because door latch structure is contained in door device, door latch structure is along with moving in car door direction 14 of closing the door, move to the first trough rim 21 and knock snap close 3, because snap close 3 is fixed on fixing on body structure, the door closing force reaction force that dead bolt 4 is subject to self-fastening button 3 promotes, and dead bolt 4 rotates, and is pushed back by dead bolt 4.I.e. state shown in state motion shown in Fig. 5 to Fig. 6.
When dead bolt 4 turns to and do not have a position-limiting action to the body 9 that latches, owing to latching, body 9 turns to lockup state by the latch effect force in direction 17 of the mechanism that automatically latches.Along with dead bolt 4 is rotated further, the length of spring drag-line shortens, and convergent force diminishes gradually, when the convergent force of spring drag-line 8 be less than locking bar 6 by the locking bar of locking bar mechanism axis of rotation 7 latch the active force in direction 16 time, locking bar 6 rotates and returns to home position.I.e. state shown in state motion shown in Fig. 6 to Fig. 7.Meanwhile, closing of the door.
The relation of hour locking lever 6 each power when rotating of unblanking: the rotatory force of locking bar motor to locking bar 6 adds the convergent force (spring drag-line 8 length is greater than spring guy cable length when hour locking lever 6 of closing the door and locking it rotates) that the reaction force of upper lock rod 6 to the spacing power of the body 9 that latches equals spring drag-line 8.
The relation of each power when hour locking lever 6 of closing the door and locking it rotates: the rotatory force of locking bar motor to locking bar 6 equals the convergent force (spring drag-line 8 length is less than spring drag-line 8 length when hour locking lever 6 of unblanking rotates) of spring drag-line 8.
Because each power magnitude relationship of above two states just can realize: when unblanking dead bolt front end 41 hold out against the second lobe 95 then locking bar 6 rotate; When closing the door and locking it, dead bolt front end 41 all rotates disengaging second lobe 95, and the body 9 that latches after not having position-limiting action to the body 9 that latches rotates, and then locking bar 6 rotates, and locking bar 6 removes the position-limiting action to the body 9 that latches.
Manually and automatically latch: can manually press locking button when pressing and need not opening car door after unlock button.Locking button control motor drives locking bar 6 to rotate to an angle to locking bar direction 15 of unblanking by locking bar mechanism rotating shaft 7, removes the stop bit effect for the body 9 that latches.The body 9 that latches turns to lockup state.I.e. state shown in state motion shown in Fig. 3 to Fig. 8.
Locking bar 6 rotates back initial position.I.e. state shown in state motion shown in Fig. 8 to Fig. 7.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
